NEUROSCIENCE OF GOALS 2
Abstract
The ways that people set, pursue, and eventually succeed or fail in accomplishing their
goals are central issues for consulting psychology. Goals and behavior change have
long been the subject of empirical investigation in psychology, and have been adopted
with enthusiasm by the cognitive and social neurosciences in the last few decades.
Though relatively new, neuroscientific discoveries have substantially furthered the
scientific understanding of goals and behavior change. This article reviews the
emerging brain science on goals and behavior change, with particular emphasis on its
relevance to consulting psychology. I begin by articulating a framework that parses
behavior change into two dimensions, one motivational (the will) and the other cognitive
(the way). A notable feature of complex behaviors is that they typically require both.
Accordingly, I review neuroscience studies on cognitive factors, such as executive
function, and motivational factors, such as reward learning and self-relevance, that
contribute to goal attainment. Each section concludes with a summary of the practical
lessons learned from neuroscience that are relevant to consulting psychology.

NEUROSCIENCE OF GOALS 3
Setting goals is easy; achieving them is hard. Why? This question has long stumped
humanity and will certainly not be answered in this article. A full explanation of why it is
hard to accomplish a goal or change old habits may never be possible. However, all
hope is not lost. Research at the interface of neuroscience and psychology has made
significant strides in uncovering the machinery behind goal pursuit. This knowledge, in
turn, provides clues about the various ways that behavior change can go wrong and
how to improve it. In this article, I present a brain-based framework for understanding
how goal pursuit works and how to facilitate behavior change. Along the way, I highlight
specific and practical lessons learned that are relevant to the science and practice of
consulting psychology.
Goals and the Four Types of Behavior
What do I mean by goals? Colloquially, a goal is any desired outcome that wouldn’t
otherwise happen without some kind of intervention. In other words, a goal is a detour
from the path of least resistance. Formally, a goal is a desired future state (an end)
coupled with a set of antecedent acts that promote the attainment of that end state
(means; see Kruglanski, Shah, Fishbach, Friedman, Chun, & Sleeth-Keppler, 2002 for a
summary). I present the informal definition first because it captures something that is
missing from the formal one: a sense of what people actually mean by the word “goals”
and how we use them. Technically, according to the formal definition, going out with
friends to celebrate someone’s birthday is goal; it is an imagined end state and one
must deploy various means to make it happen. But most people wouldn’t think of
NEUROSCIENCE OF GOALS 4
planning to go to a party later tonight as a goal. In practice, we set goals in cases where
we need to do something that hasn’t happened yet and isn’t likely to happen on its own.
The difference between the two definitions of goals highlights an important aspect of
goals and the way it is often overlooked. Goals are usually things we want but have
difficulty achieving even when we know they are achievable. Otherwise, we wouldn’t
need a goal in the first place. That sense of struggle is also captured in the term
behavior change, which I use interchangeably with goal pursuit here. It’s not engaging
in behavior, per se, but rather new behavior that is hard. To pursue what most people
call a goal involves doing something different than what has been done before. For
example, a primary incentive underlying achievement motivation (i.e., the need for
achievement) is to demonstrate one’s capability to perform well on a new or challenging
task (McClelland, 1985).
To understand why new behavior is so hard, it’s useful to think about two dimensions
that give rise to behaviors. The first dimension captures the skills, capacities, and
knowledge required to engage in a behavior. This includes mapping out the steps to
take and having the skill to execute an action, as well as related cognitive processes
such as attentional focus, inhibitory control, and working memory capacity. Because it
reflects the means used to achieve a goal, I refer to the first dimension as the way. The
second dimension captures the desire for and importance of a behavior. This includes
wanting to achieve a goal and prioritizing it over other goals, as well as related
motivational processes such as volition, intention, and the nature and strength of the
NEUROSCIENCE OF GOALS 5
drive for achievement. Because it relates to the motivation to engage in a behavior, I
refer to the second dimension as the will.
As shown in Figure 1, these two dimensions give rise to four broad types of action.
Complex-Routine behavior, in the top-left quadrant, requires some level of skill or
knowledge but little motivation. Habitual behaviors reside in this quadrant: they can be
quite complex yet are often triggered by external cues without motivation. For example,
many drivers have piloted their car somewhere familiar, such as a child’s school,
without thinking and despite an intention to go elsewhere. Indeed, a hallmark of habitual
behavior is engaging in it even (or especially) in the absence of a conscious goal to do
so (Wood & Neal, 2007). Simple-Routine behavior, in the bottom-left quadrant, requires
little skill and motivation. For example, walking, eating, and other behaviors related to
primary rewards reside in this quadrant. These behaviors are so easy and effortless that
we hardly think of them as goals at all. Because they are located in the same place on
the horizontal axis and on different places on the vertical axis, the key difference
between the first two types of behaviors is the level of skill they require. Simple-Novel
behavior, in the bottom-right quadrant, requires high motivation but low skill to
accomplish. Simple but new (and at times unpleasant) tasks such as changing a diaper
belong in this quadrant. The most interesting kind of behavior is in the fourth quadrant:
Complex-Novel behavior that requires high skill and high motivation. The goals that
people care about most reside there.
NEUROSCIENCE OF GOALS 6
Figure 1. Behavior can be divided into four broad categories defined by the level of motivation they
demand (horizontal axis) and the level of skill or ability they require (vertical axis). Behavior change
typically involves moving from left-to-right, from bottom-to-top, or both. Moving from left-to-right increases
the motivational demand (why) of an action, whereas moving from bottom-to-top increases the skill level
(how). It is useful to identify the vector of change required during goal pursuit and to target motivational
(horizontal) and cognitive (vertical) processes as necessary.
Differences between adjacent quadrants within this space are instructive. The key
distinction between a rote, unpleasant task (bottom-right) and a complex, hard one (top-
right) is skill- and knowledge-oriented. Changing one diaper doesn’t take much ability,
but building a machine to do the task for you would require decades of schooling. Both
require high levels of motivation. The lesson is that moving up and down in this space is
a matter of skill-building. In contrast, the distinction between a complex task that
happens easily (top-left) and one that requires effort (top-right) is motivational. Driving to
your child’s school is easy because you’ve done it so many times that it has become a
matter of habit. In contrast, driving for the first time in a new country relies on the same
NEUROSCIENCE OF GOALS 7
skillset but feels much harder because it forces you to focus and apply the driving and
navigation skills you already have. As you do it more it becomes easier, of course, but
you can still do it on the first attempt as long as you try hard enough. Moving from left to
right in this space, therefore, is a matter of effort more than one of skill or knowledge.
Once a person possesses the capacity and knowledge to accomplish a difficult task, the
missing piece is motivation.
Lessons learned for consulting psychology
In light of this framework, the first step to facilitating behavior change is to diagnose the
source of the difficulty. Consultants and coaches can do foundational work with their
clients early in the behavior change process to pinpoint the nature of the behavior
change and identify how the new behavior is different from old patterns. The first step to
helping a client with behavior change can involve answering these questions:
• Does the client already have the skills required for the new task?
• Is the barrier to change a lack of a way or a lack of a will?
• Is the person trying to move up, to the right, or both on the axes in Figure 1?
Once the most relevant dimension of change is identified, the second step is to drill
down to learn more about the specific nature of the motivation or skills/capacities that
will be the target. For example, consider the questions:
• If motivation, is the client lacking motivation to approach a desirable outcome or
to avoid an undesirable one (e.g., Berkman & Lieberman, 2010)?
NEUROSCIENCE OF GOALS 8
• If motivation, is the client generally unmotivated, or highly motivated to a different
goal besides than the behavior change goal?
• If skills, are they related to interpersonal abilities (e.g., empathy and perspective
taking) or executive functioning (e.g., inhibition and attentional control)?
• If skills, is it possible that the client already possesses the skills but is stuck in a
closed mindset and overly focused on one aspect of the behavior, such that a
broadening of perspective might open new avenues for progress using other
skills?
The relevant neuroscience will be quite different depending on the answer to these
questions. In the following sections, I summarize the neuroscientific literatures on the
will and the way with an emphasis on practical lessons for consulting psychology.
The neuroscience of the “way”: Executive function and cognitive control
Research on “the way” of goals and behavior change has mostly focused on constructs
such as attention, working memory, inhibitory control, and planning – collectively known
as executive function. A great deal of knowledge has been gained from neuroscientific
studies about executive function, mostly about the neural systems and circuits that
implement executive function (sometimes referred to as the task-positive network; Fox
et al., 2005), and also about how disruptions to those circuits can cause alternately
specific or broad impairment depending on the precise location and nature of the
damage (Alvarez & Emory, 2006; Stuss & Knight, 2012). Recent work has even begun
to explore the bidirectional relationship between central and peripheral nervous system
NEUROSCIENCE OF GOALS 9
functioning in the context of goals, such as how activation of the sympathetic nervous
system and hypothalamic-pituitary-adrenal axis during stress can influence executive
function (Roos et al., 2017). Together, imaging and lesion studies have illuminated
many of the mechanistic elements and processes involved in complex goal pursuit
(Stuss, 2011). This information, in turn, contains some important lessons for consulting
psychology about the capabilities and limits of executive function that are directly
relevant to goals.
Despite substantial progress in knowledge of how executive function operate at the
level of the brain, there is only sparse neuroscience research about how executive
function might be improved. What little research there is suggests that executive
function is more fixed than malleable by intervention, but there are some hints that
targeted improvement might be possible. In this section, I review recent neuroscientific
studies on executive function with respect to three questions that are pertinent to goals
and behavior change: What is the nature of executive function? Is executive function a
limited resource? And can executive function be improved with practice?
What is the nature of executive function?
Executive function refers to a suite of higher-level cognitive skills and capacities that
generally promote successful human functioning. Attention, task switching, working
memory, and inhibitory control are usually described as executive functions, though
there is debate about the precise definition of the term (Banich, 2009). Executive
function involves some degree of updating information, shifting focus between targets or
NEUROSCIENCE OF GOALS 10
mental sets, and inhibiting irrelevant or distracting information (Miyake, Friedman,
Emerson, Witzki, Howerter, & Wager, 2000). Rather than enter that debate, I will
describe broad features of executive function that are shared across most definitions.
These features are useful for providing clarity and context for the subsequent questions
regarding the limits and improvability of executive functions.

cortex (LPFC) and the ventrolateral prefrontal cortex (VLPFC), premotor cortex (pMC) and motor cortex
(MC), and the temporalparietal junction (TPJ) and supramarginal gyrus (SMG). Top Right: Medial view
featuring the dorsal anterior cingulate cortex (dACC) and ventral striatum (vS), and the dorsomedial
(dmPFC), medial (mPFC) and ventromedial (vmPFC) aspects of the prefrontal cortex. Bottom Right:

Executive function has three characteristic features: it is effortful, operates consciously,
and engaged in service of novel goals as opposed to rote or overlearned ones (e.g.,
Miyake & Friedman, 2012). Effortful means that they feel hard and must be completed
serially. In fact, emerging evidence suggests that one function of the dorsal anterior
NEUROSCIENCE OF GOALS 11
cingulate cortex (dACC; Figure 2), among several others, is to efficiently allocate
cognitive resources by tracking the amount of mental work a task will require (Shenhav,
Cohen, & Botvinick, 2016). For example, activity in the dACC scales with the upcoming
demand for control and also the potential payoff of that control (Kouneiher, Charron, &
Koechlin, 2009). It appears that the brain has dedicated regions not only to executing
control but also allocating that control to various tasks.

Executive function is conscious, which means that it occurs within awareness and
requires conscious attention. People know when they are engaging in executive
function because it becomes the center of attention in a given moment. A classic
example of executive function is mental math, such as multiplying 13 by 17. In contrast
NEUROSCIENCE OF GOALS 12
to things such as breathing or adding 1+1, you know when it happens because it
occupies all of your attention, and it is generally voluntary. The steps involved in solving
that problem recruit a host of executive functions surrounding attention: focusing
attention on the appropriate column, swapping information in and out of attention, and
restricting attention to the desired part of the operation to the exclusion of others. These
short-term memory and attentional processes are supported by complex interactions
among lateral prefrontal and parietal cortices including aspects of all three frontal gyri,
the superior frontal sulcus and precentral gyrus, and the supramarginal gyrus and
temporalparietal junction (Figure 2; Nee, Brown, Askren, Berman, Demiralp, Krawitz, &
Jonides, 2012). The role of these regions is not just to maintain information, but also to
disengage attention from irrelevant or previously-relevant information as appropriate to
the task (Shipstead, Harrison, & Engle, 2016). The importance of redirecting attention
underscores the limited-capacity nature of working memory and executive function more
generally. Extensive cognitive processes and neural resources are dedicated to gating
which information enjoys the focus of attention and which must be ignored. In this way,
executive function generally, and attention specifically, play a key role in how open or
closed we are to new ideas and perspectives during goal setting and goal striving.
In addition to feeling effortful and occupying conscious attention, a third characteristic
property of executive function is that it specializes in novel tasks. It enables humans to
do things that we’ve never done before. In fact, the basic role of the entire prefrontal
cortex has been described broadly as coordinating behavior to achieve novel goals
(Miller & Cohen, 2001). The ability of our prefrontal cortex to plan and execute novel
NEUROSCIENCE OF GOALS 13
behaviors is one of the defining characteristics of humans and one that sets us apart
from nearly all other animals. However, this ability is not unlimited. In light of the limited
capacity of attention and working memory, the prefrontal cortex has a second function
that is nearly as critical: to learn to automate novel behaviors to the point that they no
longer take up precious space in consciousness. Research on this process of habit
formation shows that as a particular behavior in a particular behavior is repeatedly
rewarded, the systems that control it shift from the dorsomedial to the ventral and
dorsolateral aspects of the striatum (Figure 2; Yin, Mulcare, Kilario, Clouse, Holloway,
Davis, et al., 2009). This shift is in part supported by the differential connectivity in these
parts of the striatum, with the dorsomedial more strongly connected to the prefrontal
and parietal cortices (involved in attention and working memory) and the other two parts
of the striatum more strongly connected to the sensory and motor cortices (Liljeholm &
O’Doherty, 2012). That the process of routinizing behavior has a robust pathway
embedded within some of the oldest structures in the brain speaks to the evolutionary
importance of offloading effortful mental activities from the cortex as early and efficiently
as possible. Thus, these regions are key for habit formation.
Is executive function a limited resource?
The answer to this question is both yes and no. Many readers will be familiar with the
concept of ego depletion, or the idea that the “active self” that implements executive
functions draws upon a finite resource that exhausts over time with repeated use, not
unlike a fuel tank (Baumeister, Bratlavsky, Muraven, & Tice, 1998). Though there are
literally hundreds of published studies showing the effect (Hagger, Wood, Stiff, &
NEUROSCIENCE OF GOALS 14
Chatzisarants, 2010), it is likely that many of those studies are false positives or
unreliable (Hagger, Chatzisarantis, Alberts, Anggono, Batailler, Birt, et al., 2016). A
large, highly powered, preregistered study recently failed to replicate the ego depletion
effect (Lurquin, Michaelson, Barker, Gustavson, von Bastian, Carruth, et al., 2016), and
a meta-analysis uncovered evidence of publication bias in the ego depletion field such
that studies finding the effect are much more likely to appear in print than those that do
not (Carter & McCullough, 2014).
On a deeper level, there is strong counter-evidence to the basic ego depletion effect, for
example that taking a short break, watching a fun film clip, or even smoking a cigarette
can reverse the effect (see Inzlicht & Berkman, 2015 for a summary). Active-self
processes such as executive function are unlikely to draw upon a limited physiological
resource if simple psychological manipulations can replenish it. Even more suggestive,
there is strong physiological evidence that the neuronal processes involved in executive
function demand no more energy than simpler functions or even than the brain at rest
(see Kurzban, 2010, for a review). There is simply no special physiological resource for
executive function to deplete. The bottom line is that people get tired when they work
hard – which is nothing new – but that, contrary to popular belief about ego depletion,
that sense of fatigue is mostly psychological and can be short circuited by a short rest
and a variety of positive experiences.
But what about the experience of depletion? Everyone has the intuition that some
mental activities – certainly including executive function – feel hard and seem to drain
NEUROSCIENCE OF GOALS 15
our energy. The answer may be found by adjusting our understanding what exactly the
limited resource is. The original formulation of ego depletion hypothesized a
physiological resource, likely centered in the brain. That prediction is no longer tenable
given the data. Newer models focus on the contributions of psychological and
motivational factors to depletion instead beyond strictly physiological ones. For
example, a shift in priorities from effortful, obligation-based, and prevention-focused
“have-to” goals to enjoyable, desire-based, promotion-focused “want-to” goals could
explain the decline in performance on tough cognitive tasks (Inzlicht, Schmeichel, &
Macrae, 2014); perhaps the “resource” is prioritization. Another possibility is that
depletion results from an interaction between psychological processes, such as
perceptions of upcoming task demands and available resources, and physiological
factors including the peripheral nervous system, hormones, and afferent inputs (Evans,
Boggero, & Segerstrom, 2016).
A psychological model that fits particularly well with the characterization of executive
function above focuses on its opportunity cost (Kurzban, Duckworth, Kable, & Myers,
2013). Because we can only focus our executive function capacity on one task at a
time, then any time we engage in one executive function task we are likely forgoing
others. The cost of what we’re giving up is reflected in the sense of effort that comes
along with executive function. The feeling of depletion, therefore, reflects the tipping
point when the cost of putting off alternative tasks begins to outweigh the benefit of
continuing on the current course of action (Berkman, Kahn, & Livingston, 2016).
NEUROSCIENCE OF GOALS 16
The evidence at this point indicates that executive function is limited in terms of
bandwidth – how much can be done or stored or attended to in a given moment – but
not in terms of duration in the ego depletion sense. That limit stems directly from the
properties of the executive function system: the facts that only a small amount of
information can be consciously accessible and operated upon in a given moment
(Unsworth, Fukuda, Awh, & Vogel, 2015), and that we actively track the processing
costs of potential cognitive operations with respect to ongoing goals (Westbrook &
Braver, 2015). For precisely this reason, executive function was likened by the
mathematician and philosopher Alfred North Whitehead to cavalry in an army,
“Operations of thought are like cavalry charges in a battle – they are strictly limited in
number, they require fresh horses, and must only be made at decisive moments.” (pp.
61; Whitehead, 1911).
Can executive function be improved with practice?
There is naturally great interest in the question of whether executive function can be
improved, expanded, or strengthened with practice given its bandwidth limitations.
Study of this kind of “brain training” is an active research area and a controversial one.
Some researchers make claims about the ability to improve executive function with
training (Jaeggi, Buschkuehl, Jonides, & Shah, 2011), though these claims have been
tempered by compelling counter-evidence (Redick, Shipstead, Harrison, Hicks, Fried,
Hambrick, et al., 2013). A fair characterization of the research to date is that people can
certainly improve on a given executive function task with practice, but there is no
NEUROSCIENCE OF GOALS 17
evidence that practice generalizes to other, even closely related tasks, and task-specific
improvements are unlikely to endure over time (Berkman, 2016).
The core issue in executive function training is transfer, or whether the improvements
on a training task generalize to other tasks. In some theories such as the Strength
Model, on which the ego depletion hypothesis is based, executive function is a common
resource that is shared across many discrete capacities (e.g., working memory and self-
control), so expanding that common resource should improve a range of executive
abilities (Muraven, 2010). However, counter-evidence to ego depletion specifically and
the Strength Model generally have raised the question about whether a common
underlying resource even exists (Inzlicht et al., 2014). A recent meta-analysis of studies
attempting to train one form of executive function, self-control, revealed a negligible
transfer effect (Inzlicht & Berkman, 2015). Additionally, at least two highly-powered
studies have failed to find generalizable training effects on executive function despite
showing practice effects on the training task (Miles, Sheeran, Baird, Macdonald, Webb,
& Harris, in press; Redick et al., 2013).
What is happening? Neuroscientific investigations provide some clues. A series of
training studies on inhibitory control, an executive function involving the prevention of
ongoing or prepotent behavior, found that performance on an inhibitory control task
improves with practice and does not transfer to other tasks. Interestingly, to the degree
that performance on the training task improved, activity in the lateral prefrontal regions
and dACC that is associated with successful inhibitory control shifted earlier in time,
NEUROSCIENCE OF GOALS 18
peaking in anticipation of the need for control (Beauchamp, Kahn, & Berkman, 2016;
Berkman, Kahn, & Merchant, 2014). This effect can be characterized as a reactive-to-
proactive shift in the neural activation involved in inhibitory control, and is akin to gently
applying a car’s brakes when a light turns yellow instead of slamming on the brakes
only upon a red light.
The observed shift in brain activity from later to earlier in time fits well with the general
characteristics of executive function described earlier. Inhibitory control feels hard and
occupies attention, so it is beneficial to the individual to automate the operation when
possible. With enough practice and exposure, the habit learning system discovers
regularities in the environment that allow the need for inhibitory control to be anticipated
using contextual cues. Just as the frequent association of a yellow light with a red light
teaches experienced drivers to automatically move their foot to the brake when seeing a
yellow, so too do participants in inhibitory control training studies learn the specific task
cues that anticipate the need for control. This cue-learning effect in training occurs
automatically (Lenartowicz, Verbruggen, Logan, & Poldrack, 2011), suggesting that
performance improvements during inhibitory control training studies are a result of the
transfer of at least some effortful behavior to the habit system. Habits increase
efficiency during goal striving.
This habit learning process also explains the lack of transfer to new tasks. The
advantages of executive function are mirrored in the limitations of the habit learning
system. Specifically, while executive function evolved to deal with novel challenges,
NEUROSCIENCE OF GOALS 19
habit learning evolved for routine ones. Habits create efficiency by shrinking the range
of responses in a situation down to one behavior. By function, they forestall new and
creative behaviors in that situation. Habitual behaviors are triggered by specific
contextual cues, which is why habits do not require vigilant and costly monitoring; that
work is offloaded to more efficient stimulus-response mappings. The tradeoff is that
habitual behaviors are necessarily tied to a particular context. If the cues that had been
associated with a response change, then the habitual response will no longer emerge.
For example, the ease of slowing on a yellow would be lost if the cue that preceded a
red light suddenly became blue instead. In the case of executive function, training
doesn’t transfer to new contexts (or tasks) because the cues are different. The brain
treats the tests of transfer as novel tasks, which is exactly what executive function
evolved to deal with in the first place.
Lessons learned from neuroscience about “the way”
The neuroscience literature on executive function offers some practical if not entirely
hopeful advice about the “way” of behavior change. The first lesson is that executive
function feels hard for a reason. It is a serial process, so the sense of effort that
accompanies executive function is a signal that working on a difficult task necessarily
means losing out on other opportunities. In other words, effort reflects an opportunity
cost. In this view, effort also signals one’s internal priorities; the more important the
alternatives are, the harder a focal task will feel. The inverse is also true: a given task
will feel relatively easy when it is more important to a person than the alternative
NEUROSCIENCE OF GOALS 20
choices. Consultants and coaches can work with clients to reflect on their priorities and
make them explicit, which can explain why some goals feel harder than others.
The mental processes related to the “way” operate sequentially, not in parallel.
Executive functions can only be performed one at a time, so the most important ones
should come first even if executive processing will not exhaust over time with use.
Based on the portrait of executive function drawn here, the factors that influence the
capacity for executive function most directly are other concurrent cognitive operations
and the relative importance of the task compared to other possibilities. Together, this
suggests that it is optimal to carve out dedicated, distraction-free time to work on
important novel tasks and challenges (Berkman & Rock, 2014). Our cognitive bandwidth
is precious and operates most efficiently in (mental) solitude. Licensing clients to
reserve work time specifically for new tasks can help.
Our executive function abilities evolved to help us deal with novel challenges. So, the
precious resource of executive function should be brought to bear on any and all
aspects of behavior change, such as goal setting, that benefit from openness to new
ideas, broadened attention, and a wide survey of possibilities. In contrast, habit
formation evolved to create efficiency by rigidly attaching one behavior to one cue.
Habits can be formed to aid in other aspects of behavior change, such as goal striving,
that benefit from a narrower focus and relatively consistent, fixed behaviors in a given
situation.
NEUROSCIENCE OF GOALS 21
Finally, there is not much evidence that executive function can be improved broadly by
focused interventions (e.g., Lumosity; Redick et al., 2013; Shute, Ventura, & Ke, 2015),
and some compelling counter-evidence. However, complex mental operations can
become routinized by leveraging the habit learning system (Foerde, Knowlton, &
Poldrack, 2006). Habit learning is facilitated when the new behavior is consistently
preceded by specific cues and then rewarded. This procedure can be particularly useful
for behavior change if the new behavior will occur repeatedly in similar contexts.
Research is underway to test whether a highly variable set of cues used in training can
broaden the range of contexts to which training effects generalize. Nonetheless, some
executive functions such as working memory may simply be fixed capacities for
neuroarchitectural reasons (Zhange & Luck, 2008). Rather than attempting to improve
executive function generally, consultants and coaches should help their clients focus on
improving specifically the skillsets relevant to the goal or new behavior. These will
improve with practice and, with some proper motivation, become habitual in time.
The neuroscience of the “will”: Motivation, Reward, and Subjective Value
The question of what motivates behavior, in a general sense, runs at least back to the
Greeks, with Plato’s famous analogy of the charioteer and his horses, through William
James and Abraham Maslow, and continues to this day. In contrast, the question of
what motivates behavior change has received considerably less attention.
Psychologists have developed taxonomies of different “stages of change” to capture
individual variability in readiness to engage in sustained behavior change
(Transtheoretical Model; Prochaska, DiClemente, & Norcross, 1992), and of different
NEUROSCIENCE OF GOALS 22
types of behaviors within a person to capture relatively self-motivated, “intrinsic” versus
more externally-motivated, “extrinsic” types of goals (Self-Determination Theory; Deci &
Ryan, 2000). Much of this work is descriptive rather than prescriptive – it says what
motivation is but does not indicate how to increase it. A person can be confidently
described as in the precontemplation stage, but there is not much evidence-backed
knowledge about moving him or her to the contemplation stage; likewise, some
behaviors are clearly extrinsically motivated, though there is a lack of prescriptive
advice about how one can transform them into intrinsically motivated ones.
As it did with studies on the “way,” neuroimaging research provides some clues about
how to increase motivation to change a specific behavior. In this section, I review
neuroscientific insights into the “way” of behavior change surrounding three questions
that are relevant to consulting psychology. Which brain systems are involved in
motivational processes? How do those systems interact with other networks in the
brain? And what does neuroscience indicate about motivating behavior change?
How and where is motivation represented in the brain?
Motivation is conceptualized here as the strength of the desire to attain a particular
outcome, irrespective of how pleasant or unpleasant the experience of actually attaining
it is. This distinction between the motivational component of a reward – “wanting” – and
the hedonic component of consuming it – “liking” – is maintained with remarkable
evolutionary consistency in the brains of both humans and animals (Berridge &
Robinson, 2003). I focus here on the “wanting” side because of its direct bearing on
NEUROSCIENCE OF GOALS 23
behavior and behavior change. Wanting a reward is closely tied with activity of
mesolimbic dopaminergic neurons, particularly within the ventral striatum and
ventromedial prefrontal cortex (Berridge, 2006; Figure 2), which is sometimes also
called the orbitofrontal cortex (Wallis, 2007). Of course, there are many other regions
and interactions involved in reward learning, but I focus on these because they are the
best characterized in terms of human functional neuroanatomy to date.
The dopaminergic reward system has been conserved evolutionarily because it plays a
critical role in the reinforcement learning cycle. When a particular behavior in a given
context it is rewarded, that behavior and context are paired and tagged with reward
value for later repetition (Rescorla & Wagner, 1972). Reinforcement learning is why
behaviors that are rewarded are likely to be repeated in the future. (This is also why the
dopamine system is implicated in addictive behavior.) The amount of cumulative,
learned reward value of a behavior is its expected value, sometimes referred to as
subjective value (Rangel & Hare, 2010). In short, subjective value represents the
amount of reward that an actor expects to receive for a given action, largely based on
past learning. This learning cycle is one of the key impediments to behavior change: old
behavior has been rewarded and new behavior has not. A protein called brain-derived
neurotrophic factor (BDNF) is important for maintaining new behaviors after engaging in
them initially because of its critical role in memory consolidation (Bekinschtein et al.,
2008). As described in the following sections, the key to launching this reward learning
and consolidation cycle is finding ways to increase the subjective value of new behavior.
NEUROSCIENCE OF GOALS 24
A notable feature of activity in the ventromedial prefrontal cortex is that it represents the
subjective values of diverse types of actions, presumably to facilitate “apples to
oranges” decisions between qualitatively different behaviors (Levy & Glimcher, 2011).
For example, activity in the ventromedial prefrontal cortex tracks the value of approach
appetitive and avoiding aversive stimuli (Tom, Fox, Trepel, & Poldrack, 2007), and also
the subjective value of a range of stimulus types, including food, money, gains for the
self and others, charitable decisions, and emotional and utilitarian benefits of moral
actions (Hare, Camerer, Knoepfle, O’Doherty, & Rangel, 2010; Hutcherson, Montaser-
Kouhsari, Woodward, & Rangel, 2015; Lebreton, Jorge, Michel, Thirion, & Pessiglione,
2009; Zaki, Lopez, & Mitchell, 2014). These findings converge on the idea that the
ventromedial prefrontal cortex plays a central role in tracking the subjective value of
different kinds of actions during choice, which strongly implicates that region in
motivational processing during behavior change.
How do motivation regions interact with other brain systems?
One way to approach the deeper issue of where motivation originates is to examine the
connectivity of its neural systems. In the same way that it is adaptive to humans and
informative to scientists that sensory and motor regions in the brain are adjacent and
highly interconnected, the regions involved in motivation are themselves intertwined
with several other brain networks. Those interrelations contain insights about how
motivation operates and how it might be increased in the service of behavior change.
NEUROSCIENCE OF GOALS 25
As Self-Determination Theory suggests, autonomously choosing to engage in a
behavior (relative to being forced) increases performance on that behavior because
autonomy is an intrinsic motive. At the neural level, autonomy also prevents a reduction
in reward system activity in the face of negative feedback, particularly in the
ventromedial prefrontal cortex (Murayama, Matsumoto, Izuma, Sugiura, Ryan, Deci, et
al., 2013). Interestingly, the ventromedial prefrontal cortex has also been found to be
active in studies of self-processing and particularly of self-affirmation, such as
considering one’s core personal values (Cascio, O’Donnell, Tinney, Lieberman, Taylor,
Strecher, et al., 2016). Brain activation related to self-affirmation during health
messaging has even been shown to predict the eventual degree of health behavior
change that would follow (Falk, O’Donnell, Cascio, Tinney, Kang, Lieberman, et al.,
2015). Finally, a meta-analysis using the Neurosynth study database (Yarkoni,
Poldrack, Nichols, Van Essen, & Wager, 2011) found that the ventromedial prefrontal
cortex was one of the largest regions of overlap between 812 studies on identity (“self”
and “self-referential” terms in the database) and 324 subjective value and reward
(“value” term in the database). The meta-analysis contained several regions along the
medial cortical wall including the ventromedial prefrontal cortex, the posterior cingulate
cortex, and the mid-cingulate. The ventromedial prefrontal cortex was the single largest
cluster to be consistently associated with both identity and value.
The overlap between intrinsic goals, core values, and subjective value has several
implications for consulting psychology. First, identity (e.g., self-concept) and subjective
value are closely functionally connected to one another. This is not a surprise given the
NEUROSCIENCE OF GOALS 26
extensive evidence from social psychology and other fields that people have
disproportionate positive regard for themselves (and behaviors related to the self)
compared to others (Greenwald, 1980; Pelham & Swann, 1989). We want, and perhaps
need, to see our selves as good (Rosenberg, 1979). Second, the value derived from
identity and other self-related processes may have a special status compared to other
sources of value (e.g., monetary) because of the high degree of overlap in the neural
systems and conceptual representation of identity and value. It may even be that
identity and value are inseparable, leading one researcher to hypothesize that the
defining function of the self is to organize and prioritize the world by assigning it
motivational significance (Northoff & Hayes, 2011). By this definition, the self-concept is
exactly the set of places, things, and actions in the world that hold value.
It is important to note that the valuation process subserved by the vmPFC reflects not
only positive value, but negative value as well. For example, just as social affiliation
holds positive value, the threat of social rejection can be highly negative in value. The
experience of social rejection invokes similar brain networks as physical pain
(Lieberman & Eisenberger, 2015). Beyond its unpleasantness, this experience can
enhance defensiveness and facilitate a stress response that detracts from other
ongoing goals because it narrows attentional focus on the social threat (Muscatell et al.,
2016).
The ventromedial prefrontal cortex and related dopaminergic motivational structures
also interact with cognitive networks, including those related to executive function
NEUROSCIENCE OF GOALS 27
(Botvinick & Braver, 2015). The ventromedial prefrontal cortex appears to be a point of
convergence where the motivational value of various options in a choice are integrated,
notably including both effortful actions that require cognitive control and also easier,
more hedonic ones (Bartra, McGuire, & Kable, 2013). For example, the dorsolateral
prefrontal cortex is functionally connected with the ventromedial prefrontal cortex when
higher-order goals such as health concerns or social factors are made salient (Hare et
al., 2010; Hutcherson, Plassman, Gross, & Rangel, 2012). There is also evidence that
the value of potential actions are reflected in the ventromedial prefrontal cortex before
any specific action plans is selected (Wunderlich, Rangel, & O’Doherty, 2010), but that
value signals provide input to downstream brain regions that are responsible for
selecting and implementing behavior (Hare, Schultz, Camerer, O’Doherty, & Rangel,
2011). Taken together, then, the emergent view from the neuroscience literature is that
the ventromedial prefrontal cortex receives a variety of value signals relevant to
decisions about behavior, and its activation reflects a dynamic value integration process
that subsequently biases behavior toward higher-valued actions. A promising route to
increasing motivation, then, is identifying the value inputs to a new behavior (i.e., the
reasons why the behavior is or is not valued) and learning ways to modulate them. I
address this possibility in the next section.
How can motivation be increased?
The neurally-informed model described above suggests that motivation is guided by an
integration of the value of features of the behavioral options. Behavior change can be
accomplished by amplifying the value of the new (goal-related) behavior, reducing the
NEUROSCIENCE OF GOALS 28
value of old (goal-counter or goal-unrelated) behaviors, or some combination of the two.
A clear example of the effectiveness of the first approach is contingency management
treatment for substance use disorders (Bigelow & Silverman, 1999), in which the value
of drug abstinence is increased with monetary incentives. A meta-analysis found this
approach to have an effect size d = 0.42 on treatment for alcohol, tobacco, and illicit
drugs, which was larger than therapy (d = 0.25) and outpatient treatment (d = 0.37), and
comparable to methadone treatment for opiate use (Prendergast, Podus, Finney,
Greenwell, & Roll, 2006). Similarly, “precommitting” to buy more healthy foods at the
risk of losing financial incentives is more effective than having the incentives alone
(Schwartz, Mochon, Wyper, Maroba, Patel, & Ariely, 2014). Monetary incentives also
increase persistence at exercise (Cabanac, 1986), endurance on a cold-pressor task
(Baker & Kirsch, 1991), and performance on a difficult cognitive task (Boksem, Meijman,
& Lorist, 2006). Simple monetary payments are an effective way to motivate behavior
change.
“Money walks,” as the saying goes, but its scarcity makes it a less than ideal option for
many goal pursuit contexts. Above, I noted the deep connections between identity and
motivation. Other researchers have, too, and are now beginning to deploy identity
interventions to increase motivation. For example, one study leveraged the fact that
most people consider willpower to be a desirable trait (Magen & Gross, 2007). The
participants in that study completed an executive function task twice, and in between
were randomly assigned to reconstrue the task itself as a measure of their own
willpower or not. Performance improved from the first to the second run only among
NEUROSCIENCE OF GOALS 29
participants whose perceptions of the task were changed from non-diagnostic to
diagnostic of willpower. Similarly, noting that identity is somewhat susceptible to
cognitive shifts such as framing, construal, or priming effects, other researchers used a
simple “noun-verb” manipulation to increase motivation for behavior change,
presumably through a subtle shift in the extent to which the new behavior is construed
as identity-relevant. For example, phrasing questions about voting intentions in terms of
identity (noun: “being a voter”) instead of an action (verb: “voting”) increased voting
intentions and actual turnout in statewide elections (Bryan, Walton, Rogers, & Dweck,
2011). In another study, participants were less likely to cheat by claiming money they
were not entitled to if that behavior was described as a (negative) identity (noun: “being
a cheater”) instead of an action (verb: “cheating”; Bryan, Adams, & Monin, 2013). Each
of these results is consistent with the idea that identity can influence motivation,
presumably by highlighting the subjective value of desired (e.g., “voter”, “willpower”) or
undesired (e.g., “cheater”) identity. This path is a promising future direction for
motivation interventions because it is low-cost, modest in scope, and easily scalable to
a broad range of populations and types of desired identities.
Finally, merely highlighting certain attributes of a behavior can alter the value placed on
that behavior. After all, our attentional bandwidth is fairly narrow, so not all relevant
properties will be equally salient at all times. For example, people’s motivation to act on
a choice option increases as attention is allocated to it (Krajbich, Armel, & Rangel,
2010). In another study (Hare et al., 2011), participants were presented with health-
versus-taste decisions with or without reminders about health. As expected, health
NEUROSCIENCE OF GOALS 30
reminders increased the likelihood of healthy choices. Tellingly, the healthiness rating of
the foods (assessed earlier, and separate from the tastiness) was strongly correlated
with activity in the ventromedial prefrontal cortex at the moment of decision, which in
turn predicted the food choice. In contrast, when unhealthy foods were selected, the
earlier tastiness ratings were correlated with ventromedial prefrontal cortex activity
during choice. The results of these studies are broadly consistent with psychological
framing effects (e.g., gain vs. loss frame; Kahneman & Tversky, 1984), whereby altering
the relative salience of the features of a decision can dramatically change it. Though
they are most often applied to decision-making, the neuroscientific evidence presented
here suggests that motivation may also be susceptible to framing effects.
In light of the present framework, I focused on ways to increase motivation that are
grounded in valuation. But there are other ways to increase motivation from
complementary lines of research that nonetheless may be connected to subjective
value. For example, Higgins has argued that people experience “value from fit” when
their regulatory style (promotion versus prevention focus) matches the particular means
through which goals are pursued (Higgins, Idson, Freitas, Spiegel, & Molden, 2003). A
similar “matching” effect on motivation has been observed with achievement motivation
and performance goals: people high in achievement motivation experience greater
intrinsic motivation when provided with performance (vs. mastery) goals, whereas
people low in achievement motivation experience greater intrinsic motivation with
mastery (vs. performance) goals (Elliot & Harackiewicz, 1994). A plausible cause of
these kinds of “matching” effects, which can be tested in future research, is that there is
NEUROSCIENCE OF GOALS 31
subjective value in experiencing fit between one’s dispositional tendencies and the
nature of the goal at hand.
Lessons learned from neuroscience about “the will”
Neuroscientific investigations of motivation have established the major brain systems for
motivation and identified ways that those systems interact with other parts of the brain.
This knowledge, in turn, contains clues about how motivation works and how to
increase it on the psychological level. Two are particularly relevant to consulting
psychology.
The first lesson surrounds the extent to which motivation is tied to the past. The neural
mechanisms of reinforcement learning are some of the most basic and ancient parts of
our brains. For good reason, we evolved to be highly sensitive to learn where we
receive rewards and to work hard to recreate the situations that brought them about.
Attempting to change behavior in a systematic way by engaging in new behaviors,
which have never been reinforced, often means working against this powerful system.
Thus, wise advice for clients that is grounded in the neuroscience of motivation and
reinforcement learning is to start behavior change with modest goals and reward even
the smallest steps toward them. New behaviors emerge slowly because they are usually
working against the power of prior reinforcement. Consultants and coaches can help
clients anticipate and understand the difficulty of behavior change by explaining the
neuroscience of reinforcement learning. Being cognizant of the challenges of behavior
change can prevent frustration on both sides.
NEUROSCIENCE OF GOALS 32
The second lesson is to leverage the intrinsic connections between the motivation
system and other parts of the brain, particularly self and identity. The elaborated web of
memories, beliefs, values, objects, and relationships that comprise our sense of self is
paralleled perhaps only by executive function in its distinctiveness to humans. And it
may offer a pathway to behavior change and goal achievement that is just as potent. A
behavior will hold greater subjective value to the degree that it is related to one’s core
values and sense of self. Identity-linked goals are more likely to be successful than
identity-irrelevant or identity-counter ones. Consultants and coaches can be particularly
helpful to clients in this arena by helping them discover core aspects of their self-
concepts and the ways those aspects are linked to the behavior change at hand. And
remember that identity is not a fixed construct, but rather is susceptible to framing,
reconstrual, and other kinds of subtle influences. To some extent, motivation can be
gained by finding ways to think about goals that makes their connection to important
parts of one’s identity salient. Sometimes it is easier for other people to make these
connections than for us because they have more distance from them (Berkman & Rock,
2014); coaches can be particularly helpful in this regard. Paying people works, too, but
connecting goals to the self-concept in various ways may be a more sustainable and
accessible approach to increasing motivation.
Conclusion
Pursing goals and changing behavior is hard. Neuroscience will never change that fact,
but it can provide some brain-level explanations for the difficulty as well as some new
NEUROSCIENCE OF GOALS 33
insights about how to mitigate it. This article reviewed the neuroscientific literatures on
the “way” of goal pursuit – the set of cognitive skills, capacities, and abilities collectively
known as executive function – and the “will” – the motivational factors that propel
behavior. Although parts of the “way” are limited by constraints that may be difficult to
change, the “will” can be influenced by incentives both within the person and without.
Though neuroscientific investigations into long-term behavior change are only just
starting to emerge they have already begun to contribute to the body of practical
scientific knowledge about goals. The science and practice of consulting psychology will
benefit directly from this research in the coming years.

Figure Captions
Figure 1. Behavior can be divided into four broad categories defined by the level of
motivation they demand (horizontal axis) and the level of skill or ability they require
(vertical axis). Behavior change typically involves moving from left-to-right, from bottom-
to-top, or both. Moving from left-to-right increases the motivational demand (why) of an
action, whereas moving from bottom-to-top increases the skill level (how). It is useful to
identify the vector of change required during goal pursuit and to target motivational
(horizontal) and cognitive (vertical) processes as necessary.

lateral prefrontal cortex (LPFC) and the ventrolateral prefrontal cortex (VLPFC),
premotor cortex (pMC) and motor cortex (MC), and the temporalparietal junction (TPJ)
and supramarginal gyrus (SMG). Top Right: Medial view featuring the dorsal anterior
cingulate cortex (dACC) and ventral striatum (vS), and the dorsomedial (dmPFC),
medial (mPFC) and ventromedial (vmPFC) aspects of the prefrontal cortex. Bottom
Right: Coronal view featuring the ventral (vS) and dorsolateral (dlS) aspects of the
striatum.
