    What is the relationship between persistent cognitive stimulation in the elderly and delaying of dementia?
    Preliminary research suggests that persistent cognitive stimulation in the elderly results in greater retention of cognitive functions and concomitantly prevents or delays
    dementing illness.
    Marianne Levon Shahsuvaryan

    New research published Feb. 2 in the Journal of the American Medical Association found that older adults with a major risk gene for Alzheimer's disease known as APOE-ε4 who ate at least one seafood serving per week showed fewer signs of Alzheimer's-related brain changes. In contrast, this association was not found in the brains of volunteers who ate fish weekly but did not carry the risk gene.

    The researchers also examined the brains for levels of mercury, which can be found in seafood and is known to be harmful to the brain and nervous system. They found that seafood consumption was associated with increased mercury levels in the brains but not the amount of beta amyloid protein plaques and tau protein tangles, the hallmarks of Alzheimer's disease.

    How can I make a prospective memory task more difficult?

    My ongoing task is to count the number of small and large squares, separately. My prospective memory task is to have participants respond with a different key press when they encounter a green square. 

    How can I make it harder for participants to identify PM targets (green squares) in this task?

    Thanks!

    Brandon

    Brandon Thomas

    Thanks, Drew! There are 6 colors (not including the green target squares). I think that you are right. Maybe, the task would be harder with more possible colors, particularly colors that are similar to green.

    Thank you as well, Luke. I think this is would definitely lower accuracy as well.

    You are right about that, Serban. All these PM paradigms are awful!

    it turns out E-prime 2.0 can interface with more simple code.  Create an inline object and use the followiing

    ObjectName.OnsetSignalEnabled = True
    ObjectName.OnsetSignalPort = &H378
    ObjectName.OnsetSignalData = 1

    OffestSignal = True 

    will turn it off, but I am using WritePort & H379, 0 

    to send a 0 to the xdat.

    you can create attributes and replace the 1at the end of the last line with c.GetAttribute("AttributeName")

    Does past experience affect what we see or what we do?

    As we trundle along through our life's pursuits, there are causal forces at work that determine our future thoughts and actions.

    Given some of the work that highlights the central role of exploratory movement for perception (that we act to detect information about the environment), it is possible that these constraints from the past determine solely our behavioral patterns, which in turn constrain the aspects of the environment that we perceive.

    The case can also be made that past experience determines our interpretations of sensory stimulation and thus the actions engaged to select those sensations (following along the lines of Helmholtz' theory of unconscious inference). Of course both of these hypotheses may also be false!

    Does past experience affect

    1. Our cognition (thoughts, ideas, beliefs, etc.)

    2. Our actions (which in turn determine the aspects of the environment we attend)

    3. Both our actions and cognition

    (a). Independent of each other

    (b). Interdependently or cyclically

    4. ...something else

    How does cognitive psychologists view behavior analysis?

    I am currently researching within a field called behavior analysis, which is essentially modern behaviorism. Researchers in this field tend to emphasize different methodologies, such as single-case designs, and often avoid statistical methods.

    In terms of psychology, behavior analysts are not interested in cognitive phenomena. This is not because they reject the existence of private events, but because they argue that cognitive events cannot be observed; only its behavioral outcomes.

    There are several papers that address how behavior analysis sees cognitive psychology. They often refer to the misuse of hypothetical constructs and unnecessary group designs. However, I was wondering if there are papers discussing behavioral analysis from the cognitive psychologists point of view?

    Most psychology textbooks will refer to behaviorism as dead, often with reference to Chomsky's critique of Skinner. According to behavior analysts, Chomsky's critique is flawed, but in mainstream psychology, behavior analysis remain a minority subdiscipline.

    So, I was wondering if there are any good articles discussing cognitive/internal/private events, and behavior analysis/behaviorism, that are written from a cognitive psychologist point of view? There are plenty such articles in behavior analysis journals, but I am wondering if the issue of cognition vs. externally observed behavior have been discussed elsewhere, from a cognitive viewpoint?

    I guess what I am asking is, what papers from cognitive psychology exist that address why behavior analysis is obsolete, and internal, private events are perfectly acceptable to investigate?

    Philip Hineline

    It is gratifying to see that paper noticed.   Several years ago, Wanchisen and I wrote a more detailed comparison of the behavior-analytic and cognitivist viewpoints.  It is cited in the paper you mention, but as a book chapter it may be difficult to obtain.  I can supply a pdf upon request.

    From subjection to passions, switching at a world governed by affections. How does this transition happen?

    The affects are the active forces which, instead of countering with rationality or intellectual love, allow us to expand our power to exist. A central point in Spinoza is this: our power and our freedom as autonomy, the more they grow, the more develop our vis existendi or vis agendi.

    But Spinoza here is problematic. He scandalized by saying that something we do not want because it is good, but it's good because we desire it, and therefore are our wishes, the desires of man as a craving animal that establish what is good. Now, why the passions are evil? Not for a reason of moralistic character, because no longer coincide, such as in the Christian tradition, with sin.

    There are passions that drag us down to unhappiness, that force us to remain in a condition of minority, mental and physical, that is, to be dependent on external forces; and passions that instead are able to regenerate and become active forces - favoring reason, for example.

    These passions are, for instance, laetitia - or joy, as normally results. But in the passions that become affections the fanciful element never disappears: the passions that become affections are not, in itself, separated from the external causes that produce them.

    At this point, I wish to tell a story.

    One day, a centipede that lived happily met a toad which asked him jokingly: "Tell me a bit ': which leg do you move first and what next?". And so he put it in such confusion that the centipede was stuck in the ditch, reflecting on what should be the method of walking.

    Two and antithetical are the considerations that bloom from this fable. On the one hand, there is the risk of immobility if we are taken by doubts, scruples, from the excesses of verification. Reflection can, in fact, "wrap” on itself and I think we all know people who are rigorously undecided. It is a behavior that leads to inertia and, in some respects, is a risk that emerges in the life of every person. Fought the temptation of toad that blocks the centipede with reflection, on the other hand you have to report the opposite defect, that of the relentless decisiveness, an attitude in very high regard today, to the point of becoming a social and political virtue.

    Without 'chaos', says Feyerabend, there 'is no knowledge, there is no progress if we do not leave the narrow path of reason. "Ideas that today form the very basis of science exist only because there were things like prejudice, opinion, passion; because these things opposed to reason; and because they were allowed to operate in their own way. Therefore we must conclude that reason can not and should not dominate everything and often must 'be defeated, or eliminated, in favor of other instances. There is not even a rule that remains valid in all circumstances and there is nothing that you can always make an appeal. Science, then, is not the single point of view that can give a reliable explanation of reality: there are myths, metaphysical dogmas of theology, other conceptions of the world with a solid philosophical and empirical basis- "It is clear that - says Feyerabend - cross-fertilization between science and these conceptions of the world 'unscientific' will need anarchism even more than it needs science.

    Having said that, there are researches on the topic of decision making and memory which further highlight the importance of emotion-cognition integration. Integration refers to a combination of parts that work together or form a whole that better achieves a common objective or set of objectives. I recall having said in a previous contribution to RG that results of the research in this area would indicate that affect and cognitions are stored separately in the brain, but that emotion influences cognition and vice versa in selective ways.

    For example, when emotional functioning is compromised, social reasoning may be impaired. Damasio and colleagues’ studies of patients with lesions to neural networks supporting emotional functioning show that social decision making is severely compromised in these patients (Damasio, Tranel, & Damasio, 1991). Other researches show that economic decision making is actually enhanced among more emotionally reactive individuals (Seo & Barrett, 2007) and that emotion bolsters both memory accuracy and a subjective sense of recollection.

    Harry Friedmann

    If i am not mistaken, Spinoza's ethics does not consist in eliminating all the passions or in sublimating them into active forces, I believe that he distinguishes between positive passions (or instincts) which increase our vitality and the negative ones which have the opposite effect. Sublimation and suppression (not repression) should be applied only to thw negative passions,

    Are there real laws in cognitive science?
    The goal of any science is to establish natural laws. A natural law can be defined as follows: if certain conditions are present a particular phenomenon always occurs. Following this defimition, a law in psychology (cognitive science) obviously can be formulated so: under certain circumstances all people always do one thing (the term “do one thing” includes not only behavior but also cognition). However, if an individual is aware of such a law, he/she is able not do this. Hence, there are no laws in psychology. One may argue that there are certain laws in psychology such as the Weber-Fechner law or the changes associated with maturation and ageing. However, these examples describe processes which are beyond conscious influence. Therefore, such processes can be related to the neural and biological rather than cognitive level of the functioning of the organism. Are there cognitive mechanisms which are potentially under conscious influence but cannot be affected deliberately?
    Manuel Morales

    "Consciousness is also the emergence and result of a complex selection of signals that occur in the deep brain. It cannot be restricted to frontal neural activity and metacognition"

    Paul Vaucher, you have touched upon the surface of the matter but did not dig deeper by not asking how emergence takes place? What causes the effect of emergence?

    With the discovery of Einstein's nonlocal hidden variables (see "A Flawed Scientific Method"), science based on knowledge of Nature's effects (effectual science) is now history. Enter the dawn of the study of the cause and effects of Nature (causal science).

    On that note, the advancement of science has begun in earnest. Prof. Vladimir A. Kulchitsky, Research Director of the National Academy of Sciences of Belarus, Institute of Physiology has formed a new hypothesis in the field of neural communication based on my research (see link).

    What are the best cognitive tests for detecting early changes prior to the onset of dementia?
    A traditional approach is to use tests of global cognitive function such as the Mini-Mental State Exam (MMSE: Folstein et al., 1975) or the Blessed-Information-Memory-Concentration Test (BIMC: Blessed et al., 1968) to assess the severity of cognitive impairment (Tombaugh and McIntyre, 1992). But are these tests sensitive enough? Most studies show either ceiling or floor effects according to the time progression into disease.

    The Rapid Cognitive Screen(RCS) can be done in 3 minutes and picks up most people with MCI as well as dementia. The SLUMS at 6 and a half minutes is very good for cognition, visual spatial and executive function. Both are better than the MMSE and equivalent to the MOCA a.

    It's likely that all tasks are, to some extent, cognitive. In that case, what are the some of the least cognitively demanding visual tasks?

    Otto Lappi

    Depends on what you view as "cognitive", of course, but if it means processes that are 1. "controlled" (require executive attention, not highly automatic), 2. subject to visual short term memory/working memory capacity limitations and 3. relatively slow, then I would suggest that "pre-attentive" visual feature pop-out in a Treisman-type visual search task is a prime example of "non-cognitive" visual processing.

      ABSTRACT: Would it be helpful to inform a driver about when a conflicting traffic situation is going to occur? We tested whether temporal orienting of attention could enhance executive control to select among conflicting stimuli and responses. Temporal orienting was induced by presenting explicit cues predicting the most probable interval for target onset, which could be short (400 ms) or long (1,300 ms). Executive control was measured both by flanker and Simon tasks involving conflict between incompatible responses and by the spatial Stroop task involving conflict between perceptual stimulus features. The results showed that temporal orienting facilitated the resolution of perceptual conflict by reducing the spatial Stroop effect, whereas it interfered with the resolution of response conflict by increasing flanker and Simon effects. Such opposite effects suggest that temporal orienting of attention modulates executive control through dissociable mechanisms, depending on whether the competition between conflicting representations is located at perceptual or response levels.

    @Asterio: 2 remarks.

    First, only time introduces an order in a dynamic system. The notion of state (or mode, if you prefer) has been introduced by humans to model the behaviors of dynamic systems. In other words, there is no state in artificial or natural artifact but only in models.

    And second, an innovation is a modification of the current state of affairs that must be coherent to be new and so, subversive: if the modification does not bring its own and new coherence, it is only an effect of the stochastic properties of a dynamic system (nothing new, nothing subversive, nothing can be learned)

      ABSTRACT: Within a week of the attack of September 11, 2001, a consortium of researchers from across the United States distributed a survey asking about the circumstances in which respondents learned of the attack (their flashbulb memories) and the facts about the attack itself (their event memories). Follow-up surveys were distributed 11, 25, and 119 months after the attack. The study, therefore, examines retention of flashbulb memories and event memories at a substantially longer retention interval than any previous study using a test-retest methodology, allowing for the study of such memories over the long term. There was rapid forgetting of both flashbulb and event memories within the first year, but the forgetting curves leveled off after that, not significantly changing even after a 10-year delay. Despite the initial rapid forgetting, confidence remained high throughout the 10-year period. Five putative factors affecting flashbulb memory consistency and event memory accuracy were examined: (a) attention to media, (b) the amount of discussion, (c) residency, (d) personal loss and/or inconvenience, and (e) emotional intensity. After 10 years, none of these factors predicted flashbulb memory consistency; media attention and ensuing conversation predicted event memory accuracy. Inconsistent flashbulb memories were more likely to be repeated rather than corrected over the 10-year period; inaccurate event memories, however, were more likely to be corrected. The findings suggest that even traumatic memories and those implicated in a community's collective identity may be inconsistent over time and these inconsistencies can persist without the corrective force of external influences.

    Can I use corrected gray matter volume (GM volume/intracranial volume(ICV)) as a covariate when examining predictive value of ICV on cognition?

    I'm currently working on a project to identify possible predictors for the level of cognitive functioning in patients matched for the degree of cerebral atrophy. I was planning on operationalizing cerebral atrophy as gray matter volumes. But to account for head size, I would correct this gray matter volume by intracranial volume which gives the fraction of the total volume which consitutes gray matter and thus corrected gray matter volume..

    The problem is that I want to examine intracranial volume itself as a possible predictor for cognitive function with corrected gray matter volume as a covariate. Is it valid to use intracranial volume and corrected gray matter volume (GM/ICV) in one regression model as predictors or would this somehow lead to statistical difficulties?

    Lasse Bang

    Not sure I understand completely what it is that you want to do. But it seems you're interested in ICV, gray matter, and white matter (if you use ICV as a predictor, and covary out gray matter volume, you're left With white matter, right?). If this is the case, why not convert both GM and WM to fractions (by dividing them With the ICV), and run separate analysis for GM, WM and ICV? Or alternatively put GM and WM in the same model. It seems that Your suggestion of ICV With GM as a covariate is in reality an Exploration of WM (and possibly CSF) volume...? It seems weird to run an analysis where the covariate is partly a function of Your predictor.

    Does the Method of Loci (MOL) interact with Working Memory (WM)?

    I investigated MOL in relation to WM:

    1. There were two groups: participants (a) exposed to MOL and (b) not exposed.
    2. I assessed the WM using a psychometrical instrument based on the multi-modal model (Baddeley & Hitch, 1974) that returns two indicators:
    • participant’s preference towards using a specific component of the WM: (1) the visual sketchpad or (2) the phonological loop;
    • WM Quotient – a general quotient reflecting the functioning of all three components described in the model (executive administrator included).

    The data was analyzed in two ways: strict scoring (serial recall) and lenient scoring (free recall).

    I could not identify an interaction between MOL exposure * Participant’s preference towards a specific component of the WM. This makes sense, as MOL is a highly complex mnemonic device and evidence from neuroimaging studies suggest that it rather reflects a general functioning of the WM than a higher score for one of its components.

    When I looked for an interaction between MOL exposure * the WM Quotient I found these surprising results:

    1. For strict scoring
    • participants exposed to MOL with a quotient lower than 109 recalled more words when compared with an uninstructed control (p < 0.05, d = 0.74)
    • participants exposed to MOL with a quotient higher than 120 recalled fewer words when compared with an uninstructed control (p < 0.05, d = 0.79)
    1. For lenient scoring the same pattern emerged:
    • participants exposed to MOL with a quotient lower than 109 recalled more words when compared with an uninstructed control (p < 0.01, d = 0.91)
    • participants with a quotient higher than 120 exposed to MOL tend to recall fewer words than those exposed to MOL (this was not significant at 0.05 => p = .07, d = 0.31).

    I dare to say that the results are meaningful, pointing out that MOL works exactly for those who need it the most, but this is intriguing as MOL efficiency is hypothesized to be related with superior functioning of the WM.

    Do you have any idea why this occurred? Or, can you point me to papers that obtained similar results?

    Thank you!

    Hello, Constantin,

    The method of loci is very effective method but has conditions to be effective. For example, it takes a while to process each item.

    The method needs to be used with many items. If we use a few items, the participants use onlyt he method of repetition. If the participant is intelligent, he can dare to use the method of repetition.

    For the participant to choose the method of repetition or method of loci, it is necessary that he has experience of having properly used the two methods, and he has seen the effectiveness of the two methos.

    The method of loci requires training to be used.

    I researched much the keyword method.

    Good luck

    If you could measure machine intelligence like a humans IQ, what would you measure and how?

    What level of intelligence do machines actually need/posses and how can this be compared. If the community is to create a Machine Quotient (MQ), how would this be compared to human cognition?

    Dear all,

    This question has been around for decades, and is still open.

    In my opinion, the notion of IQ is not very appropriate for machines, basically because there is no normative population of machines to derive any meaningful score. Also, the (re)use of items found in IQ tests for machine evaluation doesn't seem to be very appropriate:

    Nonetheless, I also think that machine intelligence evaluation is possible, but it must be based on different principles. If you are interested in some of these ideas, you can have a look at

    and for a more comprehensive view of the evaluation of cognitive abilities:

    In any case, it is a fascinating problem that will become more and more relevant in the near future.

    Best wishes,

    Jose.
