Primacy of information about means selection over outcome selection in goal attribution by infants

It has been shown that, when observing an action, infants can rely on either outcome selection information (i.e., actions that express a choice between potential outcomes) or means selection information (i.e., actions that are causally efficient toward the outcome) in their goal attribution. However, no research has investigated the relationship between these two types of information when they are present simultaneously. In an experiment that addressed this question directly, we found that when outcome selection information could disambiguate the goal of the action (e.g., the action is directed toward one of two potential targets), but means selection information could not (i.e., the action is not efficiently adjusted to the situational constraints), 7- and 9-month-old infants did not attribute a goal to an observed action. This finding suggests that means selection information takes primacy over outcome selection information. The early presence of this bias sheds light on the nature of the notion of goal in action understanding.     

Cognitive and neural modeling of dynamics of trust in competitive trustees

Trust dynamics can be modeled in relation to experiences. In this paper two models to represent human trust dynamics are introduced, namely a model on a cognitive level and a neural model. These models include a number of parameters, providing the possibility to express certain relations between trustees. The behavior of each of the models is further analyzed by means of simulation experiments and formal verification techniques. Thereafter, both models have been compared to see whether they can produce patterns that are comparable. As each of the models has its own specific set of parameters, with values that depend on the type of person modeled, such a comparison is non-trivial. To address this, a special comparison approach is introduced, based on mutual mirroring of the models in each other. More specifically, for a given parameter values set for one model, by an automated parameter estimation procedure the most optimal values for the parameter values of the other model are determined in order to show the same behavior. Roughly spoken the results are that the models can mirror each other up to an accuracy of around 90%.     

All holes are the same: Emerging from the confusion

The author describes a type of mental development in which the primitive libidinal value of faeces and urine is kept unaltered all through adulthood. In this instance, individuals harbour fantasies of projective identifi cation with the internal parents, denying their real dependence, which leads to a pseudomaturity. These fantasies are usually accompanied by anal and genital masturbation and have intense aggressive content. Furthermore, there is a signifi cant confusion among all body orifi ces, leading to an inability to distinguish the self from the object, the inner world from outside reality. Individuals with this type of development can only maintain limited object relations and have highly erotized excretory activities. Manipulation of faeces may occur. This structure works as a defence against breakdown, but may also provide pleasure as it gives the illusion of omnipotent control of the object, as typical in pathological organizations. The author presents clinical material and discusses the diffi culties of the analysis, in which the patient tries to seduce the analyst into colluding with his mental functioning, primarily as a means of communication as well as a projection of his despair and his disbelief in the analyst's ability to help him.     

The how and why of disagreement among perceivers: An exploration of person models

Impression formation has been conceptualized as a process whereby perceivers form person models of others, describing what the person is like and why (Park, DeKay, & Kraus, 1994). If they exist, person models could help explain why there appears to be little consensus in personality judgments; perceivers forming different models of a person would also view them differently on trait and affect ratings. Two experiments were conducted to test assumptions of the person-model paradigm using naturalistic targets. The structure of person models was examined, along with their content. Results demonstrated that three distinct person models emerge for each target and that the majority of perceivers can easily identify with one of the three models. We found that person models were valid across different groups of perceivers, and that the models differed in terms of masculinity-femininity and affect. Implications for the person model formulation process are discussed.     

The impact of affective and cognitive focus on attitude formation

We examined the effects of unobtrusive affective and cognitive focus on attitude formation. To induce focus, participants worked on a word-search puzzle consisting of either affective (e.g., emotion) or cognitive (e.g., reasoning) words. They then read positive and negative affective and cognitive information about a new attitude object. In the affective focus condition, evaluations were more congruent with the valence of the affective information than they were in the cognitive focus condition, where evaluations were more congruent with the valence of the cognitive information than they were in the affective focus condition. Affective focus also resulted in enhanced recall of affective information. The effects on evaluations remained stable over time, whereas effects on memory disappeared. Finally, affective focus was associated with faster response times, suggesting enhanced accessibility of affect-based attitudes. The present research shows that an affective or cognitive focus leads to the formation of different attitudes.     

Concept formation in non-verbal categorization tasks in brain-damaged patients with and without aphasia

The study of thinking in patients with aphasic language impairments has long since been considered as means for learning about neuropsychological processes. In the present investigation, a non-verbal categorization task was used, requiring the subjects to sort several common objects according to different principles. The experimental group consisted of aphasic patients with motor and sensory aphasia. Two control groups were used, one consisting of normal subjects and the other of non-aphasic patients with injuries in the right hemisphere of the brain. The sorting behaviour was analysed according to several aspects. The final product of the categorization was assessed, as well as the behavioural processes observed during the sorting. The results were expressed in terms of different conceptual levels achieved. The results of the investigation showed that the aphasics were significantly inferior to normal controls both quantitatively and qualitatively in all sorting aspects. Possible mechanisms underlying the deficiencies in the sorting behaviour of the two aphasic groups were discussed.     

Stimulus equivalence and transitive associations: A methodological analysis

When a number of two-stimulus relations are established through training within a set of stimuli, other two-stimulus relations often emerge in the same set without direct training. These, termed "transitive stimulus relations," have been demonstrated with a variety of visual and auditory stimuli. The phenomenon has served as a behavioral model for explaining the emergence of rudimentary comprehension and reading skills, and the development of generative syntactic repertoires. This article considers the range of relations that can arise between a given number of stimuli in a class, the number of directly established two-stimulus relations necessary for the emergence of transitive relations, the forms that training sets of stimuli can take, and the number of transitive two-stimulus relations that can be induced without direct training. The procedures needed to establish and assess transitive stimulus control, the possible interactions between the training and testing procedures, and the constrainst these interactions place upon the analysis of transitive stimulus control are also examined. The present analysis indicates that in a transitivity test, choice among such stimuli may be controlled by (1) the relation between the sample and the positive comparison stimulus (transitive stimulus control), (2) the relation between the sample and the negative comparison stimulus (S- rule control), and (3) possible discriminative properties that may inadvertently be established in the positive and negative comparison stimuli (valence control). Methods are described for distinguishing these three forms of stimulus control.     

Psychology and social control

The history of social control applications of psychology and the likelihood of a future increase in their importance are assessed. The effects of military funding of psychological research and the social consequences of very widespread unemployment are specifically considered. It is argued that psychology and related areas of cognitive science and neuroscience may well become increasingly relevant in the development of the technical components of such techniques rather than in providing ideological justifications for their use.     

After-affects: How automatic evaluations influence the interpretation of subsequent, unrelated stimuli

Findings from three experiments suggest that participants’ automatic evaluations of subliminally presented objects influenced how they interpreted subsequent, unrelated objects. Participants defined homographs (Experiment 1), categorized objects and people (Experiment 2), and made person judgments (Experiment 3) that all could be disambiguated in either a positive or negative way. Participants’ responses to the ambiguous targets were evaluatively consistent with their automatic evaluations of preceding, semantically unrelated objects. The findings suggest that one’s automatic evaluations can influence deliberate judgments of subsequent stimuli, even when the only shared dimension between the initially evaluated objects and the judged objects is an evaluative one. The implications of these findings are discussed with regard to possible mechanisms of evaluative priming as well as previous research concerning evaluative priming effects on social judgment.     

Psychodynamic assessment of changes in children with autism under psychoanalytic treatment

In this article the authors report insights into autism developed through their extensive experience of psychoanalytic therapy with children with autism. The fi rst stages of body psychic development are seriously disrupted by this pathology, resulting in primitive anxieties of falling and of being liquefi ed. These anxieties are connected to the fragile development of body ego and of its related spatiotemporal organisation. The changes in children observed by the authors during the therapeutic process lead them to offer a psychodynamic assessment tool, which revolves principally around the development of body ego. After the initial state of 'severe autism', the authors describe three stages: the stage of 'recovery of the skin' (Bick); the established 'symbiotic phase', subdivided into 'vertical then horizontal splitting of the body ego'; and fi nally the stage of 'individuation'. First, the authors describe the principal psychoanalytic approaches to autism and refl ect on the links possible with nonpsychoanalytic work.
