The neural basis of humour processing

Authors:

Abstract

Humour is a vital component of human socio-affective and cognitive functioning. Recent advances in neuroscience have enabled researchers to explore this human attribute in children and adults. Humour seems to engage a core network of cortical and subcortical structures, including temporo-occipito-parietal areas involved in detecting and resolving incongruity (mismatch between expected and presented stimuli); and the mesocorticolimbic dopaminergic system and the amygdala, key structures for reward and salience processing. Examining personality effects and sex differences in the neural correlates of humour may aid in understanding typical human behaviour and the neural mechanisms underlying neuropsychiatric disorders, which can have dramatic effects on the capacity to experience social reward.
Laughter occurs in all cultures worldwide
and is a universal component of the human
experience1,2. In human infants, laughter
is one of the first social vocalizations3, and
laughter’s early onset (at approximately
4months of age) in response to the actions
of others suggests that it has innate com-
ponents1,2,4. In contrast to laughter, which
is generally understood to be a reflex-like
physiological–behavioural response, humour
is believed to represent a rather complex
higher-order emotional process5. Specifically,
“humour is a broad term that refers to any-
thing that people say or do that is considered
funny and tends to make others laugh, as
well as the mental processes that go into
both creating and perceiving such an amus-
ing stimulus, and also the affective response
in the enjoyment of it(REF.6). Despite such
multiple usages and definitions of humour,
nearly all of us can easily recognize humour
when we experience it7,8.
There are many theories that explain
the pervasive role of humour in society.
Among these, three theories are related to
the functional role of humour in a proximal
(psychology and physiology) or ultimate
(natural selection) sense. According to the
superiority theory, aggression is regarded as
an essential component of humour, particu-
larly so if playful6. In line with this theory,
a central function of humour is to maintain
social order and to reinforce social bond-
ing9 by allowing people to express disa-
greeable feelings in a more positive way. A
related theory, tension-relief, conceptual-
izes humour as a mechanism for physi-
ological release of tension6. Hence, people
experience humour and engage in laughter
because it dispels pent-up stress9. Another
potential role of humour in society is sug-
gested by linking it with sexual selection
theory10,11. In so doing, humour is proposed
to act as a fitness indicator that provides
mating partners with information about
underlying mate quality, especially for
women judging men. In addition to these
three theories on the functional role of
humour, one prominent cognitive humour
theory attempts to account for how peo-
ple understand humour. The ‘incongruity
detection and resolution’ theory suggests
that humour requires two elements: the
introduction of incongruity, created by the
simultaneous presence of two habitually
incompatible elements, which produces
an unexpected violation of expectations,
convention, fact or intention, and results
in cognitive arousal; and incongruity reso-
lution associated with amusement6,1214.
Together, these frameworks for humour
point to the breadth and depth of humour’s
role and functionality in human experience.
Here, we propose that rigorous scientific
study of the neural basis of humour will shed
light on the importance of humour to the
human experience. Our understanding of
how individual variation influences commu-
nication and adaptation (both in health and in
illnesses in which humour may be adversely
affected; for example, brain disorders such as
autism, major depression and schizophrenia)
may also be enhanced through brain-based
research. The aim of this article is to provide a
comprehensive summary of the recent func-
tional MRI (fMRI) findings that shed light on
the neurobiological basis of humour apprecia-
tion in humans and to outline directions for
future research. We provide a brief overview
of the relevant mental and social operations
that are inherent to humour processing, fol-
lowed by a detailed discussion of brain-based
fMRI studies that examine humour and its
potential clinical relevance. We conclude with
a brief summary and offer perspectives on
the future direction of neuroscientific studies
ofhumour.
Evolution and benefits of humour
Humour can lead to positive emotion15 and
is thought to serve important evolutionary
socio-emotional purposes. Extant find-
ings highlight its key role in building and
maintaining relationships, emotional health
and cognitive function6. Humour helps us
to communicate ideas, attract partners,
boost mood and cope in times of trauma
and stress16–22. These beneficial manifesta-
tions are complemented at the physiological
level, with humour acting as a natural stress
antagonist that can potentially enhance
the cardiovascular, immune and endocrine
systems23–27. Examples of such positive
effects of humour on physiology include
faster cardiovascular recovery, decreased
cortisol levels after stress and improved
natural killer cell activity. Furthermore, as a
prototypical positive human cognitive state,
humour can increase life satisfaction by
building resilience28. Resilience is defined as
the ability of most people, when exposed to

extraordinary levels of stress and trauma, to
maintain normal psychological and physi-
cal functioning and avoid serious mental
illness29. Although the above work provides
some evidence that humour can have heal-
ing effects, it is important to recognize that
more rigorous research is still needed, par-
ticularly studies including control groups
and applying established (psychological)
definitions of humour30,31.
Although we share some of the basic
properties underlying laughter and smiling
with other hominids, mainly related to their
association with a social safety and play sig-
nal (BOX1), humour defined as mental play
with words and objects and conceptualized as
enjoying incongruity” (REF.32) is recognized
as a human-specific characteristic4.
Given these considerations, it is surpris-
ing that far less research attention is paid to
elucidating the development and function
of positive emotional states in humans, such
as those attained through humour, than
of basic negative emotional states such as
fear33–35 (but also see REF.26).
Functional neuroanatomy of humour
During the past 15years, several fMRI stud-
ies (predominantly in adults) have probed
the neural substrates of humour apprecia-
tion in humans (TABLE1). In these studies,
the stimulus modalities used can be funda-
mentally dissociated into two groups: verbal
and visual. Verbal stimuli comprise either
written or auditory information and can be
further differentiated into phonological ver-
sus semantic jokes, funny versus nonsense
or ‘garden path’ punchlines, and (non)funny
versus (un)ambiguous sentences versus
noise. In turn, visual stimuli differ mainly
according to their manner of presentation,
which can be static (for example, cartoon
images) or dynamic (for example, short
movie clips) (also see BOX2). Accordingly,
humour appreciation has been found to
activate a large set of cortical and subcorti-
cal brain areas subserving many cognitive
and emotional functions (see below and
FIG.1). Similar activation patterns seem to
emerge when using parametric data analysis
procedures to capture brain areas in which
humour processing positively correlates with
subjective funniness ratings (FIG.2; TABLE1).
This is in agreement with results from one
fMRI investigation36 showing that subjective
funniness rating or labelling during humour
appreciation does not disrupt the brain’s
response to humour but even seems to
have sustaining effects, particularly in brain
regions associated with emotion.
Despite the use of various stimulus modal-
ities recruiting distinct brain areas in a task-
specific manner, as well as the application of
different analysis approaches (main effects
contrasts versus parametric modulation),
there is a convergence of the findings indi-
cating two dissociable, albeit interdepend-
ent, core processes of humour appreciation
inhumans.
A cognitive component is reliably asso-
ciated with (residual30) incongruity detec-
tion and resolution, which is also referred
to as humour comprehension in a recent
verbal humour processing model14. This
cognitive component is thought to rely
fundamentally on basic visual, auditory
and/or verbal processing (in a task- and
stimulus-modality-dependent manner),
as maintained by activity in the visual and
auditory cortices; and on the activation of
language and semantic knowledge areas,
including the (particularly left) inferior fron-
tal gyrus (IFG; Brodmann area 45 (BA45),
BA46 and BA47) and the temporal pole
(TP; BA38). In the case of stimuli requiring
the juxtaposition of mental states (theory
of mind (ToM)), humour comprehension
will also recruit activity in cortical midline
structures, including the medial prefrontal
cortex (mPFC), posterior cingulate cortex
(PCC) and precuneus (PREC), as well as the
(anterior and posterior) superior temporal
gyrus (STG) and superior temporal sulcus
(STS). Finally, because incongruity can also
involve error detection or monitoring, dorsal
anterior cingulate cortex (ACC) activation
has been reported in such contexts (for
references, see TABLE1). After a thorough
review of the literature, we suggest that all
of these mechanisms converge towards a
core processing area of incongruity detec-
tion and resolution, which not only includes
the temporo-parietal junction (TPJ; BA22,
BA39 and BA40) but also extends ventrally
into the temporo-occipito-parietal junction
(TOPJ; BA37, BA39 and BA40)37. This area
of the human brain receives multimodal
input from different sensory afferents and
is also known to be activated during self-
related processing and ToM. Furthermore,
it is involved in the detection of unexpected
stimuli of behavioural relevance and linked
Box 1 | The evolution of humour in humans: genetic and cultural influences
Humour in humans is thought to be tightly linked structurally and conceptually with the expression
of Duchenne laughter1, a genetically predisposed4,91 and inherently positive emotion that elicits
‘genuine’ or ‘real’ smiles92. Derived from the primate relaxed open-mouth play face93, such
Duchenne laughter is primarily elicited in situations in which a sudden unexpected change in
events occurs within a safe social surrounding. This includes ‘rough-and-tumble’ play, tickling,
physical mishaps and pleasant surprise in infants (for example, a ‘peek-a-boo’ face expressed by a
parent), which are referred to as ‘proto-humour’ (REF.11). By contrast, Duchenne laughter elicited
by incongruity-based conceptual humour, primarily in adults, is associated with ‘formal’ attempts
at inducing laughter11. However, proto-humour and Duchenne laughter are often tightly linked
with one another. Darwin associated humour with “tickling of the mind” (REF.94), and there seems
to be a relationship between the propensity to laugh when tickled and to laugh at and use humour
(in adults)95. Together, the spontaneous laughter of human infants, tickling and formal adult
humour all share what is essentially a phylogenetically and ontogenetically conserved structure
and context, referred to as non-serious social incongruity11.
Despite their evolutionary origin being linked with genetic predispositions, Duchenne laughter
and humour are not considered to be completely resistant to modulatory influence. In this
context, cultural norms and related learning mechanisms are mentioned as key shaping factors11.
A good illustration of such relations is the cultural variation observed in the subject matter of
humour, which can vary from toilet- and sex-based humour to political humour and span a wide
spectrum of cultural institutions and customs11. Furthermore, it is known that learning processes
within different cultures strongly influence the context, frequency, intensity and expression of
laughter as a function of display rules and varying norms and customs11. Along these lines, the
comparison of three studies investigating the genetic versus environmental components of
humour in adult monozygotic versus dizygotic twins from the United Kingdom, Australia and
North America is noteworthy96. The principal measure was individual differences in humour
expression according to four distinct humour styles, of which two are positive (affiliative and
self-enhancing) and two are negative (aggressive and self-defeating). The results revealed that,
for studied twins from Australia and the United Kingdom, additive genetic and environmental
factors accounted for the variance in all four humour styles. For twins from North America,
additive genetic and environmental factors accounted for the variance in the two positive
humour styles but not for the two negative humour styles, for which variance was accounted for
solely by environmental factors. Such findings probably demonstrate cross-cultural differences in
what are deemed to be acceptable uses of humour and suggest that there is more cultural
pressure surrounding negative rather than positive humour. However, future studies from
different cultures are needed to confirm and extend these findings.

to increased connectivity with ventral fron-
toparietal areas associated with attention and
decision making38–41. The TOPJ therefore
seems ideally suited for incongruity detec-
tion and resolution. However, it should
be noted that incongruity detection and
resolution have not yet been functionally
and anatomically dissociated, because they
occur in rapid temporal succession (virtu-
ally at the same time), making it difficult to
separate them with current fMRI methods.
Investigations using electroencephalography
or magnetoencephalography might be better
suited to address this issue42–44.
An emotional component is also con-
sistently found to be involved in humour
appreciation. Although this emotional
component recruits the insula, the ventral
ACC and the supplementary motor area
(SMA), it is primarily associated with
increased activity in mesocorticolimbic
dopaminergic brain areas (that is, the
ventral tegmental area, substantia nigra,
nucleus accumbens, ventral striatum and
ventral mPFC) (FIG.1). Changes in the
blood-oxygen-level-dependent (BOLD)
signal in mesocorticolimbic dopaminergic
areas are known to increase during various
reward-related responses45, and such activa-
tions are also commonly reported by means
of correlational analyses with subjective fun-
niness ratings (FIG.2; TABLE1). Accordingly,
this is generally understood to represent a
positive feeling of mirth or reward in the
course of humour appreciation, which is
also referred to as humour elaboration14.
The exact nature of positivity associated
with humour, however, is not yet completely
understood. This is probably for several
reasons. First, increased subjective ratings of
funniness also correlate with BOLD signal
change during humour processing in cogni-
tive areas comprising the TPJ, TP, mPFC,
ACC, PCC and PREC (FIG.2). Therefore,
heightened funniness scores could also be
linked to humour properties other than
the basic sense of reward typically linked
with dopaminergic signalling. Second, and
related to this notion, most neuroimaging
studies of humour appreciation compare
funny stimuli to a neutral control condition
but not to a similarly positive state without
humour. There are only two investigations
to date that used such a positive-state con-
trol37,46. Although these studies were con-
ducted in children, they show evidence that
humour appreciation differs from a more
generalized response to reward; this differ-
ence is probably related to the satisfaction
of detecting and resolving the incompatible
elements of humour. More extensive testing
of optimal control conditions for humour
studies is required.
Humour is also reliably associated
with activation of the amygdala (FIGS1,2).
Although the human amygdala is known
to be involved in reward-related mecha-
nisms47, its functional profile is more
comprehensively understood to resemble
a relevance detector48–50. The amygdala
is attributed a key role in selecting from
a constant incoming stream of diverse
information those inputs that are most
relevant to the goals or intentions of the
organism at a given moment in time. Such

Box 2 | Different types of humour used in fMRI research
The extant literature using functional MRI (fMRI) to study humour
includes different types of stimuli for humour induction. Below is a
summary of the most prominent categories, which are dissociated by
stimulus modality (verbal versus visual) and presentation mode (static
versus dynamic).
Static visual stimuli
Visual pun. This kind of humour uses visual resemblance as the main
element inducing incongruity, which is usually achieved by one (or
more) part of an image having different possible meanings. In the
provided example (see the figure, part a), the diagonal line can stand
for the sea (activated through the fin) or the mountain (activated
through the skis).
Semantic pun. Such humour is based on pure semantic relations and not
visual resemblance (as in a visual pun). In the provided example (see the
figure, part b), the patient has died, which can be seen on the monitor in
the form of an angel flying away. There is no visual resemblance
between the angel and the expected flatline, which indicates no
heartbeat on an electrocardiogram.
Theory of mind humour. In contrast to visual and semantic puns, this kind
of humour requires mentalizing abilities in order to get the joke. In the
given example (see the figure, part c), one has to understand that the
woman does not know what will happen to her, whereas the man does;
such discrepancy in subjective knowledge represents the central element
of incongruity.
Language-dependent visual humour. Under certain circumstances,
incongruity during visual humour perception is introduced through the
image caption and not the image (that is, the drawing, cartoon, and so on).
This is differentiated from ‘sight gags’ containing a legend that are still
experienced as funny when the caption is removed97.
Control conditions for static visual humour usually consist of images
with an irresolvable incongruity98 or stimuli in which the incongruent
(funny) element has been removed97.
Dynamic visual stimuli
Such humour is usually presented by means of short movie clips, taken
either from professional comedy programmes or from amateur footage,
including scenes in which humans and/or animals display unusual
behaviour and/or the shown action takes an unexpected (incongruous)
twist. Some studies use full-length episodes of a comedy series, in which
humour will not be purely visual: there will also be an incompatibility
between behaviour and speech comparable to language-dependent
visual humour (see above).
Control stimuli normally include comparable ‘neutral’ scenes with no
funny elements. In rare cases, positive or rewarding but non-funny scenes
have been used as more appropriate controls37,46,61.
Verbal stimuli
There is a wide variety of verbal jokes that originate from different
structural levels of language99. These are phonetic, (lexico-)semantic,
morphological, phraseological and syntactical. Phonetic and semantic
jokes are the main types of jokes used in fMRI humour research.
Phonetic jokes. The most commonly used underlying principle is
ambiguity caused by an identical or very similar pattern of sounds
conveying different meanings. For example: “Why did the golfer wear two
sets of pants? He got a hole in one.” (REF.10 0).
Semantic jokes. In this type of humour, there is either a deviation
against lexico-semantic rules or a violation at the pragmatic
communicative level that introduces ambiguities in the interpretation
of the described situation. This can be achieved by the use of synonyms
or antonyms (words with the same or opposite meaning, respectively),
homonyms (phonetically identical but semantically different words),
polysemy (in which a lexical item has a range of different meanings) or
paronymy (in which words sound similar but mean different things)99.
Different baselines have been used for verbal jokes. Usually, the
punchline is exchanged with a logical or congruent statement. However,
in some cases, the punchline has been modified to include either
nonsense or ‘garden path’-like elements; the latter introduces non-funny
and irresolvable incongruity14,101.

‘biological value’ seems to be prominently
related to the processing of salience, sig-
nificance, ambiguity and unpredictability50.
Accordingly, humour appreciation is likely
to activate the amygdala because it contains
not only several of the above processing
components related to basic incongruity
detection and resolution but also a posi-
tive interaction signal with high intrinsic
social significance. Amygdala involve-
ment in humour appreciation therefore
underscores the importance of humour as
a social process for humans and highlights
the susceptibility of this process to various
moderating influences, such as personality,
sex and the presence of neuropsychiatric
disorders that modify the biological value
ofhumour.
Personality, sex and brain disorder
Considerable evidence from data in adults
indicates that humour is linked with
positive individual, as well as group, out-
comes6,11,20,22,51–53. Conversely, humour per-
ception has been observed to be reduced in
conditions associated with negative mood
states, such as major depression54, and in
people suffering from social anxiety55.
One way to investigate such associations
is to examine brain activity in response to
humour as a function of personality traits
that are risk factors for psychopathology,
such as introversion–extraversion and
neuroticism56. To date, two fMRI inves-
tigations in adults57,58 have used such an
approach. Preliminary results showed that
positive traits such as emotional stability
(the opposite of neuroticism) and experi-
ence seeking (related to extraversion) may
enhance humour processing, as indicated
by increased activity in the lateral prefrontal
and temporal cortices, hippocampus and
mesocorticolimbic circuits. Conversely, high
introversion has been found to correlate with
amygdala activity during humour apprecia-
tion. These preliminary data indicate that
both cognitive and emotional processes
during humour appreciation can be moder-
ated by personality traits in adults and are in
agreement with behavioural data showing
that extraversion is related to the amount of
positive affect in response to humour59,60.
Comparable data from earlier developmental
stages are scarce, but a recent study provides
preliminary evidence that, in 6–13-year-old
children, humour processing is already mod-
erated by temperament traits such as emo-
tionality, shyness and sociability61. Overall,
these findings suggest that humour appre-
ciation may be susceptible to individual
differences in personality in both children
and adults, highlighting the need for further
research into the developmental trajectories
of this uniquely human positive cognitive
state by means of larger cross-sectional and/
or longitudinal studies.
The findings noted above are comple-
mented by data from two fMRI investi-
gations probing sex differences in adult
humour processing62,63. The first study
showed that the TOPJ, TP and IFG were
activated during humour appreciation in
both sexes. However, activity in the IFG was
stronger in females, who displayed addi-
tional BOLD signal change in mesocorti-
colimbic reward areas. These findings were
interpreted as indicating a greater degree of
executive processing and language-based
decoding, as well as a greater reward net-
work response and possibly less reward
expectation in females62. The notion of
stronger emotional reactivity in females
during humour perception was supported
by the second study in adults63. An examina-
tion of sex differences in humour apprecia-
tion in 22 children (aged 6–13years) found
similar activation patterns to those reported
in adults46. Stronger activity in the midbrain
and amygdala in response to humour was
observed in girls compared with boys, who
in turn displayed stronger activation in the
ventral mPFC. This supports the notion of
increased reward response and salience in
girls, perhaps owing to less reward anticipa-
tion during the task. Overall, such emerging
data on sex differences in humour apprecia-
tion in both adults and children support
the fitness indicator hypothesis of humour
Figure 1 | Meta-analysis of activations during humour processing. The meta-analysis results in
the figure show that humour processing recruits a large set of cortical and subcortical brain areas
that maintain both the cognitive and the emotional components of humour in a stimulus modality-
and task-dependent manner. Literature review suggests that humour appreciation converges on
two core processes: ‘incongruity detection and resolution’, as maintained by the temporo-occipito-
parietal junction; and reward and salience processing involving mesocorticolimbic areas and the
amygdala. Each sphere represents peak coordinates of reported activation clusters from humour stud-
ies using functional MRI (TABLE1) in Talairach coordinates, projected on a template single-subject
flattened structural brain image. Computed contrasts to derive these activations include funny ver-
sus non-funny, theory of mind (ToM) funny versus non-ToM funny, semantic funny versus phonologi-
cal funny (and vice versa), natural amusement versus instructed smiling, language funny versus
‘sight gag’ funny (and vice versa), funny versus irresolvable incongruity, incongruity resolution
versus nonsense, funny versus positive, and funny versus ‘garden path’ (for a definition of humour
conditions, please refer to BOX2).

function related to sexual selection theory
(see above and REF.11 ) by illustrating that
females may be more receptive to, and dis-
play less reward expectation from, humour,
regardless of age. Further research to confirm
and extend such findings isneeded.
Behavioural, imaging and brain lesion
findings associated with humour and psy-
chopathology have also been published.
For example, one line of research reports
deficient humour processing in autism64–67.
These results are linked to the individuals
difficulties in understanding the social
aspect of humour requiring ToM and,
more generally, in integrating cognitive and
affective information. Prominent neural
substrates for such functions are the TPJ
and (right) IFG, the activity of which has
been found to be altered in people with
autism64,66,67.
Other research indicates impaired
humour appreciation in schizophrenia68–71.
Affected individuals display reduced humour
recognition associated with impaired ToM
abilities and diminished mPFC activity in
response to jokes requiring the attribution
of mental states (BOX2). Therefore, in both
autism and schizophrenia, humour appre-
ciation deficits seem to be predominantly
related to disturbed ToM and/or socio-
emotional integration mechanisms, and thus
cognitive humour processing (see above).
In accordance with such findings, there are
data from patients with focal brain damage
linking humour-processing deficits with
impaired (right) frontal lobe function67.
Finally, a link between altered humour
appreciation and cataplexy has been
noted72,73. Cataplexy refers to episodes of
sudden and transient loss of muscle tone
triggered by strong emotions, usually occur-
ring in association with the complex sleep–
wake disorder called narcolepsy. Results
from fMRI investigations in patients suffer-
ing from cataplexy converge in suggesting an
overdrive of the emotional humour circuitry
(ventral striatum and amygdala), which
might be linked with a compensatory sup-
pression of hypothalamus activity by cortical
inhibitory regions.
Taken together, these data on personal-
ity, sex differences and psychopathological
conditions associated with humour appre-
ciation demonstrate the psychological,
psychiatric or even neurological variation
related to both the cognitive and the emo-
tional components of humour. Moreover,
many of these effects can be observed
in both adults and young children. Such
findings highlight the clinical relevance
of investigating humour appreciation by
means of neuroimaging methods at different
developmentalstages.
Conclusions and perspective
Humour is a ubiquitous component of
human cognition, communication and
interaction. It has numerous potential ben-
eficial effects on personal, psychological and
physical well-being, and positively influences
social and group processes.
On a functional neuroanatomical basis,
humour appreciation recruits a wide range
of brain areas, which differentially activate
as a function of distinct humour-inducing
stimulus modalities and task requirements.
Nonetheless, all of these auxiliary mecha-
nisms seem to converge towards two core
processes of humour appreciation: incongru-
ity detection and resolution (the cognitive
component); and a feeling of mirth or reward
(the emotional component). Whereas the
cognitive component seems to rely principally
on activity in the TOPJ, the emotional com-
ponent appears to involve mesocorticolimbic
dopaminergic pathways and the amygdala.
Our perspective is that none of the regions or
networks underlying human humour appre-
ciation (for example, sensory processing,
working memory, incongruity detection and
resolution, and reward) evolved individually
or in concert with another expressly for that
function. Rather, the combination of several
of these regions and/or networks in the ser-
vice of humour appreciation became increas-
ingly prominent in human society because of
its importance in processing social informa-
tion. Although the differentiation between
cognitive and emotional components of
humour is not new1, evidence from recent
neuroimaging studies strongly supports this
differentiation.
Future studies focused on the neurosci-
ence of humour should address several
outstanding areas of research. Perhaps most
importantly, more data are needed to eluci-
date the development of humour throughout
the human lifespan and its modulation by
various factors such as culture, personality,
sex, age and intelligence quotient (IQ). Such
investigations are particularly desirable if
Figure 2 | Meta-analysis of activations involving parametric modulation of humour. The meta-
analysis results in the figure show that the degree of funniness reported by participants positively
correlates with brain activity in response to humour in a large set of cortical and subcortical brain areas
maintaining both the cognitive and the emotional components of humour. These areas include the
temporo-parietal junction, mesocorticolimbic circuit and amygdala. Each sphere represents peak
coordinates of reported activation clusters from humour studies using functional MRI (TABLE1) in
Talairach coordinates, projected on a template flattened structural brain image. Parametric modula-
tion analyses were always based on funny versus non-funny contrasts.

they incorporate longitudinal study designs.
However, we add the caveat that the current
fMRI scanner environment limits the extent
to which humour can be studied, particularly
in comparison to naturalistic settings. Other
functional imaging modalities, such as func-
tional near-infrared spectroscopy74–76, might
provide methodological advantages from this
standpoint. It also seems vital to extend exist-
ing data with research using appropriate con-
trol conditions and differentiating between
incongruity detection and resolution, and
‘proto-humour’ versus ‘formal’ humour
(BOX1). Such experiments will shed more light
on the neural bases of human humour appre-
ciation. In addition, we note that the present
article emphasizes the clinical relevance of
humour related to neuropsychiatric disor-
ders (such as autism, schizophrenia, anxiety,
depression and cataplexy). However, there are
many more domains in which the positive
relationship between humour and coping and
resilience could be more extensively explored
in the future. As briefly mentioned above, it
has been suggested that humour exerts many
beneficial effects on physical and mental
health, which is of potential interest in several
medical settings, including procedures with
ill children, older individuals or those in pal-
liative care19,77–82. Furthermore, humour-based
(psycho)therapy and counselling may help
to promote healthy relationships in general,
including marriage and family settings in
particular83–86. Finally, the use of humour has
been suggested to be beneficial in education
for both learning and testing, as well as in
the workplace, where it can enhance social
functioning, ease negotiation and mediation,
and support leadership87–90. Such preliminary
findings on the beneficial effects of humour
on physical and mental health need to be fur-
ther evaluated under stringent scientific con-
ditions. A deeper understanding of the neural
bases of humour appreciation nonetheless
seems relevant for many different contexts,
and has the potential to positively affect the
well-being of a wide range of individuals.

... In our study, we examined humor processing -a high-level cognitive capacity which plays an important role in our lives (Martin and Ford, 2018). The mechanisms of humor processing are not fully understood, while at the neural level a wide range of regions was associated with humor processing (Vrticka et al., 2013). To this extent, the lateral prefrontal cortex is particularly interesting. ...
... Humor is prominent in our lives, while the positive impact of humor spans from improving interpersonal communication (Martin and Ford, 2018) to reducing stress (Abel, 2002) and relieving pain (Weisenberg et al., 1995;Tse et al., 2010). Humor processing has been investigated using a variety of paradigms, including auditory and visual verbal material as well as static images and short movies (for review: Vrticka et al., 2013). Neural substrates of humor have been investigated primarily using fMRI. ...
... Neural substrates of humor have been investigated primarily using fMRI. Interestingly, no clear localization of humor processing has emerged so far, while activations have been found across the whole cerebral cortex (for review: Vrticka et al., 2013). In our study, we used fNIRS in combination with a 3-min comedy movie -an approach that has not been used previously in humor research. ...

Naturalistic stimulation (i.e., movies and auditory narratives of some minutes’ length) has been a powerful approach to bringing more real-life experiences into laboratory experiments. Data-driven, intersubject correlation (ISC) analysis permits examining to what extent activity in a specific brain region correlates across participants during exposure to a naturalistic stimulus, as well as testing whether neural activity correlates with behavioral measures. Notably, most of the previous research with naturalistic stimuli was conducted using functional fMRI (fMRI). Here, we tested whether a naturalistic approach and the ISC are feasible using functional near-infrared spectroscopy (fNIRS) - the imaging method particularly suited for populations of patients and children. Fifty-three healthy adult participants watched twice a 3-min segment of a Charlie Chaplin movie while we recorded the brain activity on the surface of their prefrontal cortex using fNIRS. In addition, an independent group of 18 participants used a continuous scoring procedure to rate the extent to which they felt that different parts of the movie fragment were funny. Our two findings were as follows. First, we found higher-than-zero ISC in fNIRS signals in the prefrontal cortex lobes, a result that was particularly high in the oxygenated channels during the first repetition of the movie. Second, we found a significant negative correlation between oxygenated brain signals and ratings of the movie’s humorousness. In a series of control analyses we demonstrated that this latter correlation could not be explained by various non-humor-related movie sensory properties (e.g., auditory volume and image brightness). The key overall outcome of the present study is that fNIRS in combination with the naturalistic paradigms and the ISC might be a sensitive and powerful research method to explore cognitive processing. Our results also suggest a potential role of the prefrontal cortex in humor appreciation.
... Numerous disciplines, including sociology [6], psychology [7,8], philosophy [9], and neuroscience [10] have investigated humour from different perspectives. In computer science and, especially, affective computing, the automatic measurement of humour has attracted increasing research interest in recent years, e. g. [11,12,13]. ...

Humour is a substantial element of human affect and cognition. Its automatic understanding can facilitate a more naturalistic human-device interaction and the humanisation of artificial intelligence. Current methods of humour detection are solely based on staged data making them inadequate for 'real-world' applications. We address this deficiency by introducing the novel Passau-Spontaneous Football Coach Humour (Passau-SFCH) dataset, comprising of about 11 hours of recordings. The Passau-SFCH dataset is annotated for the presence of humour and its dimensions (sentiment and direction) as proposed in Martin's Humor Style Questionnaire. We conduct a series of experiments, employing pretrained Transformers, convolutional neural networks, and expert-designed features. The performance of each modality (text, audio, video) for spontaneous humour recognition is analysed and their complementarity is investigated. Our findings suggest that for the automatic analysis of humour and its sentiment, facial expressions are most promising, while humour direction can be best modelled via text-based features. The results reveal considerable differences among various subjects, highlighting the individuality of humour usage and style. Further, we observe that a decision-level fusion yields the best recognition result. Finally, we make our code publicly available at https://www.github.com/EIHW/passau-sfch. The Passau-SFCH dataset is available upon request.
... It has been suggested that the left TPJ plays a role in the "resolution" of semantic incongruities that characterise humour. An influential theory posits that appreciating humour requires the "detection" of an incongruity between two incompatible elements that produce unexpected violations of conventional cognitive expectations and the ensuing "resolution" of the incongruity that is reached by re-establishing the semantic coherence within the setup of the humour context [145][146][147]. fMRI investigations have demonstrated that humour understanding depends on a network of areas that include the MFG-IFG, the temporal poles and the TPJ [145]. ...

Experimental and theoretical studies have tried to gain insights into the involvement of the Temporal Parietal Junction (TPJ) in a broad range of cognitive functions like memory, attention, language, self-agency and theory of mind. Recent investigations have demonstrated the partition of the TPJ in discrete subsectors. Nonetheless, whether these subsectors play different roles or implement an overarching function remains debated. Here, based on a review of available evidence, we propose that the left TPJ codes both matches and mismatches between expected and actual sensory, motor, or cognitive events while the right TPJ codes mismatches. These operations help keeping track of statistical contingencies in personal, environmental, and conceptual space. We show that this hypothesis can account for the participation of the TPJ in disparate cognitive functions, including “humour”, and explain: a) the higher incidence of spatial neglect in right brain damage; b) the different emotional reactions that follow left and right brain damage; c) the hemispheric lateralisation of optimistic bias mechanisms; d) the lateralisation of mechanisms that regulate routine and novelty behaviours. We propose that match and mismatch operations are aimed at approximating “free energy”, in terms of the free energy principle of decision-making. By approximating “free energy”, the match/mismatch TPJ system supports both information seeking to update one's own beliefs and the pleasure of being right in one's own' current choices. This renewed view of the TPJ has relevant clinical implications because the misfunctioning of TPJ-related “match” and “mismatch” circuits in unilateral brain damage can produce low-dimensional deficits of active-inference and predictive coding that can be associated with different neuropsychological disorders.

... But all things considered, although we tried to lower listeners' time devoted to the experiment as much as possible, listening to 50 melody versions can still be tedious, and fatigue or boredom can counteract humor perception. Furthermore, there might always be a slight risk that self-report judgments on bipolar rating scales cannot provide strong objective results, despite that it has been shown that subjective, self-reported humor ratings positively correlate with psychophysical measures [67], [68]. ...

Background Melodic expectations were manipulated to investigate the nature of tonally incongruent melodic final notes that may elicit humor in listeners. To our knowledge, this is the first experiment aiming at studying humor elicitation in music with the use of empirical, quantitative methods. To this aim, we have based the experiment on the incongruency/resolution theory of humor and the violations of expectations in music. Our goal was to determine the amount of change, that is, the degree of incongruency required to elicit humor. Methods We composed two simple, 8-bar long melodies, and changed their final notes so that they could randomly finish on any semitone between an octave upwards and downwards with respect to the original, tonic final note. This resulted in 25 versions for both melodies, including the original final notes, for each semitone. Musician and non-musician participants rated each version of each melody on five 7-point bipolar scales according to goodness of fit, humor, beauty, playfulness, and pleasantness. Results and conclusions Our results showed that even a single change of the final note can elicit humor. No strong connection was found between humor elicitation and the level of incongruency (i.e., the amount of violation of expectation). Instead, changes to the major-mode melody were more likely to be found humorous than those to the minor-mode melody, implying that a so-called playful context is necessary for humor elicitation as the major melody was labelled playful by the listeners. Furthermore, final notes below the original tonic end note were also found to be less humorous and less fitting to the melodic context than those above it.
... One plausible explanation was to look at the neural mechanism of humor from two distinct angles: cognition and emotion, using functional magnetic resonance imaging [6,8]. The cognitive and emotional aspects of humor-processing affect the frontotemporal and mesocorticolimbic brain areas known for language [9] and pleasure [10,11] operations, respectively. Therefore, abnormalities in these brain areas could result in symptoms of depression like social withdrawal and anhedonia [12] thereby underlining the importance of humor. ...

While humour and wordplay are among the most intensively studied problems in the field of translation studies, they have been almost completely ignored in machine translation. This is partly because most AI-based translation tools require a quality and quantity of training data (e.g., parallel corpora) that has historically been lacking for humour and wordplay. The goal of the JOKER@CLEF 2022 workshop was to bring together translators and computer scientists to work on an evaluation framework for wordplay, including data and metric development, and to foster work on automatic methods for wordplay translation. To this end, we defined three pilot tasks: (1) classify and explain instances of wordplay, (2) translate single terms containing wordplay, and (3) translate entire phrases containing wordplay (punning jokes). This paper describes and discusses each of these pilot tasks, as well as the participating systems and their results.KeywordsMachine translationHumourWordplayPunsNeologismsParallel corporaEvaluation metricsCreative language analysis
Article
Sexual humor involves neural mechanisms related to both humor and sexual arousal. However, evidence on the role of the amygdala in processing sexual humor is lacking. Unlike erotic stimuli that directly involve a biological drive, sexual humor gains its value through learned associations. Processes related to responding to erotic versus monetary rewards have been identified in the lateral orbitofrontal cortex (lOFC) along a postero-anterior axis, but it is less clear whether these processes are also active during the appreciation of sexual humor. Results showed the processing of sexual humor appreciation in the amygdala. Psychophysiological interaction (PPI) analysis further identified functional connectivity in the amygdala-midbrain coupling during sexual humor versus monetary gains appreciation. The present study provides evidence demonstrating roles for the posterior OFC (pOFC) and anterior OFC (aOFC) in distinguishing between sexual (sexual humor and erotic) and non-sexual (monetary) rewards. The experience of sexual pleasure induced by erotic rewards involves phylogenetically and ontogenetically older regions in the pOFC, while the experience of receiving monetary gains involves the aOFC. This study also provides additional insights into sexual humor appreciation in the pOFC, with findings of a postero-anterior dissociation in the processing of sexual humor appreciation. PPI analysis revealed functional connectivity in the pOFC-amygdala coupling in response to both types of sexual rewards versus monetary rewards. Together, our results suggest that the amygdala serves as a reward hub, especially in processing sexual humor versus monetary gains appreciation. Functional connectivity analysis showed amygdala-midbrain and pOFC-amygdala coupling during the appreciation of sexual humor.

Combining the methods of neuroscience and economics generates powerful tools for studying the brain processes behind human social interaction. We argue that hedonic interpretations of theories of social preferences provide a useful framework that generates interesting predictions and helps interpret brain activations involved in altruistic, fair and trusting behaviors. These behaviours are consistently associated with activation in reward-related brain areas such as the striatum and with prefrontal activity implicated in cognitive control, the processing of emotions, and integration of benefits and costs, consistent with resolution of a conflict between self-interest and other-regarding motives.

All published research examining effects of humor and laughter on physical health is reviewed. Potential causal mechanisms and methodological issues are discussed. Laboratory experiments have shown some effects of exposure to comedy on several components of immunity, although the findings are inconsistent and most of the studies have methodological problems. There is also some evidence of analgesic effects of exposure to comedy, although similar findings are obtained with negative emotions. Few significant correlations have been found between trait measures of humor and immunity, pain tolerance, or self-reported illness symptoms. There is also little evidence of stress-moderating effects of humor on physical health variables and no evidence of increased longevity with greater humor. More rigorous and theoretically informed research is needed before firm conclusions can be drawn about possible health benefits of humor and laughter.

From a psychological perspective, humor is essentially a positive emotion called mirth, which is typically elicited in social contexts by a cognitive appraisal process involving the perception of playful, nonserious incongruity, and which is expressed by the facial and vocal behavior of laughter. In social interactions, humor takes on many different forms, including canned jokes, spontaneous witticisms, and unintentionally funny utterances and actions. Psychological functions of humor include the cognitive and social benefits of the positive emotion of mirth, and its uses as a mode of social communication and influence, and as a way of relieving tension, regulating emotions, and coping with stress. Popular conceptions of laughter have changed dramatically over the past two or three centuries, from being viewed as essentially aggressive and somewhat socially inappropriate to being seen as positive, psychologically, and physically healthy, and socially desirable. The meaning of the word humor has also evolved from a narrow focus on benign and sympathetic sources of mirth distinguished from more aggressive types of wit, to its use as a broad umbrella term to refer to all sources of laughter. Although humor has important psychological functions and touches on all branches of psychology, and there is a sizable and growing research literature on the topic, mainstream psychology has paid relatively little attention to it until now.

According to recent theory, many of the interpersonal functions of humor derive from its inherently ambiguous nature due to the multiple concurrent meanings that it conveys. Because of this ambiguity, humor is a useful vehicle for communicating certain messages and dealing with situations that would be more difficult to handle using a more serious, unambiguous mode of communication. Importantly, a message communicated in a humorous manner can be retracted more easily than if it were expressed in the serious mode, allowing both the speaker and the listener to save face if the message is not well received. These insights concerning the ambiguity and face-saving potential of humor have been applied by theorists and researchers to account for a wide variety of social uses of humor, including self-disclosure and social probing, decommitment and conflict de-escalation, enforcing social norms and exerting social control, establishing and maintaining status, enhancing group cohesion and identity, discourse management, and social play. The multiple interpersonal functions of humor suggest that it may be viewed as a type of social skill or interpersonal competence. Employed in an adept manner, humor can be a very useful tool for achieving one's interpersonal goals.
