Learning algorithm for an intelligent decision making system based on multi-agent neurocognitive architectures

The paper presents the formalism of an intelligent decision-making system based on multi-agent neurocognitive architectures, which has an architectural similarity to the human brain. An invariant of the organizational and functional structure of the intellectual decision-making process based on the multi-agent neurocognitive architecture is developed. An algorithm for teaching intelligent decision-making systems based on the self-organization of the invariant of multi-agent neurocognitive architectures is presented. Using this algorithm, an intelligent agent was trained and the architecture of the learning process was built on the basis of an invariant of neurocognitive architecture. Further research is related to training an intelligent agent in more complex behavior and expanding the capabilities of an intelligent decision-making system based on multi-agent neurocognitive architectures.     

The effect of failure and frustration on reflective and impulsive children

Failure was hypothesized to be an antecedent of a reflective style of responding and frustration an antecedent of an impulsive style. Failure and frustration were manipulated with an anagrams task and their effect on latency and errors on the Matching Familiar Figures Test (MFF) was assessed. The Failure group increased its latency on the MFF, replicating Messer's (1970) research, while the Frustration group showed a nonsignificant decrease in latency. There was a relation between an increase in latency and a decrease in errors on the MFF. The findings were related to research on the “frustration effect” in children and were interpreted as suggesting the need for research on the effects of the amount and patterning of failure on reflection-impulsivity.     

Unconscious goal activation and the hijacking of the executive function

Building on research on unconscious human goal pursuit and the dynamic nature of our mental and physical world, this study examined the idea that an unconsciously activated goal hijacks executive control for its own attainment. This "hijacking" of the executive function by an unconscious goal should be evidenced by impaired performance on an unrelated task relying on executive control. The results of 6 experiments show that subliminal activation of a socializing goal, or an idiosyncratic personal goal, or an academic goal, harmed participants' performance on an executive function task, such as inhibition of prepotent responses and detection of text errors during reading. These effects were unique to executive control, were similar when the goal was activated consciously, and were independent of task motivation and perceived inter-goal relatedness between the primed goal and task goal. Furthermore, an unconscious goal occupied executive control to advance itself more strongly when the goal had personal value. Implications for theory and research on unconscious goal pursuit and the executive function are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Effect of environmental support on implicit and explicit memory in younger and older adults.

The study addressed 2 major issues: whether there are age differences on an implicit word-stem-completion task and whether age differences on both implicit and explicit memory would decrease with increased environmental support. A total of 287 Ss were presented with words in an incidental learning task with structural or semantic processing. Following 2 filler tasks, Ss received an implicit or an explicit word-stem-completion task. The number of letters in the stem varied from 2 to 4. Results yielded an Age x Memory Task dissociation such that there were large age differences on the explicit task and no age difference on the implicit task, regardless of whether Ss aware of the memory test were included or excluded. There was no evidence that environmental support improved older adults' performance more than that of younger adults on either memory task.     

Investigating Emotions Philosophically1

Among today's philosophers of emotion there are, on the one hand, those that do “conceptual analysis” and, on the other hand, those that oppose such an approach as empirically naïve, as sanctifying our ordinary use of words and as based on an analytic/synthetic distinction and an outmoded theory of meaning. This paper is an attempt to show why this critique is misplaced and to clarify how conceptual investigations of emotions relate to empirical investigations.     

THE LONG-TERM PSYCHOLOGICAL EFFECTS AND TREATMENT OF HOLOCAUST TRAUMA

The present article gives an overview of the long-term psychological effects of Holocaust traumatization on survivors and their offspring and suggests possible treatment strategies for these client populations. Based on interviews with and treatment of hundreds of such clients and on an extensive review of the literature, it also represents some of the cumulative experience of AMCHA, an Israeli treatment center devoted specifically to this issue.     

Social Class,Merit and Equality of Opportunity in Education

The paper offers to substantiate a claim about the so-called Meritocratic Conception of how educational opportunities ought to be distributed. Such a conception holds an individual’s prospects for educational achievement may be a function of that individual’s talent or effort levels but should not be influenced by their social class background. The paper highlights the internal tension in the Meritocratic Conception between on the one hand a prohibition on the influence of social class on educational opportunities and on the other a permission to allow unequal educational opportunities on the basis of talent and effort. This tension obtains because individuals’ talent and effort are themselves subject to influence by social class. The paper makes a positive case for an interpretation of the Meritocratic Conception that resolves this tension in favour of an egalitarian version, such that social class represents an objectionable determinant of unequal educational prospects even when its influence is mediated through the cultivation of talent and effort. This argument is further supported through an explanation that the character of social class as a systemic social source of the structure of individuals’ opportunities makes it an objectionable influence on educational opportunities.     

Obtaining guilty knowledge in human intelligence interrogations: Comparing accusatorial and information-gathering approaches with a novel experimental paradigm

Substantial research has assessed interrogations seeking to obtain a criminal confession, and consequently much has been learned regarding the potential problems with confession evidence. However, an increasing focus on counter-terrorism, and therefore intelligence interrogations, reveals an obvious gap in the literature. Intelligence interrogations are primarily focused on collecting information from individuals as opposed to a confession linked to an alleged event, and little of the extant psychological literature can speak directly to such a scenario. The current research developed an experimental paradigm to test interrogation approaches in an intelligence-gathering context, providing a method for gathering empirical data on human intelligence collection. In the first implementation of this paradigm, accusatorial and information-gathering interrogation strategies were tested using a procedure high in psychological realism. Results indicate that an information-gathering approach yields more relevant information than an accusatorial approach and leads to more diagnostic impressions by third party observers.     

Role of intertrial interval following an escape or avoidance response in bar-press avoidance

In three experiments, rats learned bar-press avoidance as a function of the intertrial interval following an escape or an avoidance. The general hypothesis is that the length of these intervals affects bar-press avoidance differentially, depending on whether an avoidance follows an escape (avoidance/escape) or an avoidance (avoidance/avoidance) on the previous trial. Specifically, it is proposed that short escape ITIs will facilitate avoidance/escape and avoidance/avoidance, while avoidance ITIs will have no effect on avoidance responding. The results tend to support this hypothesis. The shorter the intertrial interval following an escape, the higher the probability of both measures: avoidance/escape and avoidance/avoidance. No effect of avoidance interval was found on avoidance/avoidance. Unpredictedly, however, it was found that in comparison to a very short intertrial interval following an avoidance (0.5 sec), relatively long intervals (5 and 45 sec) facilitate avoidance/escape. These results were interpreted as mainly reflecting nonassociative factors such as shock-produced activity.     

The progressive heritage of guidance: a view from the left

As one part of a larger progressive movement, the guidance and counseling movement has typically supported progressive programs in the schools and in society as a whole. While most counselors point with pride to such a progressive heritage, a case can be made that the effect of progressivism is to prop up existing structures and resist fundamental change in societal institutions. In this article the author discusses four ideals that are commonly held by the progressive and the counseling movements, pointing out some of the destructive effects these ideals have on societal change efforts. The four ideals discussed are: (a) an emphasis on access to opportunity (pluralism), (b) an emphasis on pragmatism, (c) an emphasis on adjustment, and (d) an emphasis on individualism.     

The Ethical Perspective: An Identity Theory of the Psychological Influences on Moral Choice

The 2008 Presidential Address presents the theory of ethical perspective, an identity theory of moral psychology designed to detect the psychological influences on moral choice. Part 1 treats findings on altruism and genocide as an analytical lens through which we can gain insight into political and moral behavior. Part 2 describes moral psychology as a field, presenting a new and broader conceptualization for the discipline. Part 3 outlines an identity theory of moral choice that focuses on the critical role of the ethical perspective, to suggest how an empirically based theory of moral choice looks in practice. Part 4 concentrates on the basic assumptions underlying the theory of ethical perspective. It presents empirical evidence that supports this theoretical framework, from fields as diverse as neuroscience and primatology to child development and linguistics, thus demonstrating political psychology's important links to other disciplines. In addition to presenting a new theory of moral psychology, designed to fill an important gap in the literature on ethics and moral choice, the Address treats studies of altruism and genocide as an illustration of research that reveals broader insight into the nature of political psychology as a discipline.     

Age-of-acquisition and cumulative frequency have independent effects

Lewis (1999) argued that effects of age of acquisition (AoA) are entirely attributable to cumulative frequency. He reported an instance-based model in which the number of instances of the stimulus stored in memory predicts reaction time. We note four aspects of the literature on AoA that cannot be explained by this instance-based approach. Firstly, an effect of AoA has been observed in the absence of an effect of frequency. Secondly, an effect of AoA has been observed when cumulative frequency has been controlled. Thirdly, the effect of AoA is dependent on task. Fourthly, the effect of word frequency is dependent on stimulus modality. Lewis reported an experiment in which participants make a decision based on identity-specific semantic information to celebrity faces to demonstrate an effect of the number of instances in memory, which he interpreted as an effect of AoA. We note that effects of AoA have been found in lexical and perceptual tasks, but to date all attempts to demonstrate an advantage for early-acquired items in semantic classification tasks have failed. We conclude that the effects of AoA cannot be attributed solely to the effects of cumulative frequency.     

Intelligence, Personality and Performance on Case Studies

Standard individual difference antecedents of two stages in the case study assessment process were determined in a sample of 305 students. We found that antecedents to the problem identification and analysis stages of case assessment differed. Specifically, we tested intelligence and personality traits as the predictors and found that openness to experience was significantly positively correlated with an individual’s score on problem identification and that general intelligence was significantly positively correlated with an individual’s score on analysis. Additionally, there was a positive relationship between extraversion and agreeableness and an individual’s analysis score and a significant negative relationship between conscientiousness and an individual’s score on problem identification. Moreover, intelligence and conscientiousness interacted to predict an individual’s analysis score with high conscientiousness partially compensating for an individual’s relatively low intelligence.     

Test-Taker Reactions to the Selection Process: Effects of Outcome Favorability, Explanations, and Voice on Fairness Perceptions

This study examined the effects of providing an explanation and voice on fairness perceptions and reactions of test takers under favorable and unfavorable selection decisions. Participants took either a cognitive ability test or an overt integrity test in a simulated selection situation. Then, the voice manipulation was introduced. Participants were informed of the hiring decision with or without an explanation. Results showed that type of test had effects on procedural fairness perceptions such that these reactions were more positive when a cognitive ability test was used. The results of voice and explanation manipulations on fairness perceptions indicated that providing an explanation had a positive effect on perceptions but, surprisingly, face-validity perceptions were less favorable when participants had voice opportunity.     

TIMEX: A simple IBM AT C language timer with extended resolution

The simple timing method of reading the IBM-BIOS tick counter is extended from 55-msec to 54-µsec resolution by reading the 8254 hardware counter. Subroutine timex( ) implements the timer in Borland Turbo C on an IBM AT and on a PC or XT if the 8253 timer chip is replaced with an 8254 chip. A more limited version operates on an unmodified PC or XT.     

The informational basis of social judgments: Memory for informative and uninformative arguments

This study investigates the encoding and retrieval of arguments in an opinion formation task. It is based on a model of opinion formation that partitions the latter process into initial encoding, elaborative encoding, integration, and decision. According to this model elaborative encoding depends on two factors: (i) the informativeness of the arguments and (ii) their thematic relatedness. Since it is reasonably well established that the likelihood of retrieving an argument is an increasing function of the amount of elaboration performed on it, the first hypothesis is straightforward, namely, that the memory for an argument will increase with its informativeness and with its thematic relatedness to other arguments. The second hypothesis assumes that by dint of their closer association with the decision, informative arguments occupy a more central position in the representation of an opinion than uninformative ones. This implies that an informative argument should be accessed and reported prior to an uninformative argument, even when differences in retrievability (i.e., probabilities of recall) are controlled. The findings were consistent with such an analysis.     

Objective Consequentialism and Avoidable Imperfections

There are two distinct views on how to formulate an objective consequentialist account of the deontic status of actions, actualism and possibilism. On an actualist account, what matters to the deontic status of actions is only the value of the outcome an action would have, if performed. By contrast, a possibilist account also takes into account the value of the outcomes that an action could have. These two views come apart in their deontic verdicts when an agent is imperfect in an avoidable way, viz., when agent brings about less good than she could. In this paper, I offer an argument against actualism that draws on the connection between moral obligation and practical reasons.     

The reinforcement of four interresponse times in a two-alternative situation

Pigeons pecked for food in a two-key procedure. A concurrent variable-interval variable-interval schedule of reinforcement for two classes of interresponse times was arranged on each key. A visual stimulus set the occasion for potential reinforcement of the four operant classes: shorter and longer interresponse times on left and right keys. In Exp. I, the relative frequency of respones on a key equalled the relative frequency of reinforcement on that key. In Exp. II, the relative frequency of an interresponse time equalled the relative reciprocal of its length. In Exp. III, the relative frequency of an interresponse time was a monotonically increasing function of its relative frequency of reinforcement. These functions relating the relative frequency of an interresponse time to its relative length and to its relative frequency of reinforcement were the same as if there had been no second key. Also, the distribution of responses between keys was independent of the relative frequency of an interresponse time on either key. Experiment IV replicated Exp. I except that choices between keys were controlled by a stimulus that signalled the availability of reinforcement on the right key. A comparison of Exp. I and IV suggested that the relative frequency of an interresponse time on one key generally was independent of behavior on the other key, but that the number of responses per minute on a key did depend on behavior on the other key.     

Motor anticipation failure in infants with autism: a retrospective analysis of feeding situations

Previous studies on autism have shown a lack of motor anticipation in children and adults with autism. As part of a programme of research into early detection of autism, we focussed on an everyday situation: spoon-feeding. We hypothesize that an anticipation deficit may be found very early on by observing whether the baby opens his or her mouth in anticipation of the spoon's approach. The study is based on a retrospective analysis from family home movies. Observation of infants later diagnosed with autism or an autism spectrum disorder (ASD) (n = 13) and infants with typical development (n = 14) between 4 and 6 months old show that the autism/ASD group has an early anticipation deficit.     

Automatic attention to stimuli signalling chances and dangers: Moderating effects of positive and negative goal and action contexts

Current research on automatic attention allocation focuses on the questions whether there is an asymmetry in attentional biases towards negative and positive stimuli and whether these attentional biases are influenced by situational variables. In an experiment with N = 48 participants, automatic allocation of attention to chance and danger stimuli was investigated. Attentional capture was generally larger for chance stimuli than for danger stimuli. Additionally, attentional bias was influenced by the outcome focus of the actual goal orientation. Results revealed an incongruence effect of goal orientation on attentional biases: Attentional capture for the chance and danger stimuli was comparatively stronger when an outcome focus of opposite valence had been induced.
