Vygotsky and beyond: horizons for the future of psychology / Vygotski y más allá: horizontes para el futuro de la psicología

In this article some usually overlooked aspects of Vygotsky’s work are presented. First, the understanding of the mediation system as a trans-organic, extended branch of the psychological system. Second, the semantic nature of conscience and the systemic neuropsychological organization of higher functions. Third, the leading role played in the psychic system by directive functions. Fourth, the understanding of human evolution as open and permanently provisional. Last, a reference is made to the role of psychology in the process of human auto-evolution, which Vygotsky viewed as a mission.     

Kea cooperate better with sharing affiliates

Controlled studies that focus on intraspecific cooperation tasks have revealed striking similarities, but also differences, in abilities across taxa as diverse as primates, fish, and birds. Such comparisons may provide insight into the specific socio-ecological selection pressures that led to the evolution of cooperation. Unfortunately, however, compared to primates data on birds remain relatively scarce. We tested a New Zealand psittaciform, the kea, in a dyadic cooperation task using the loose-string design. During trials our subjects were in separate compartments, but obtained a common reward that could be divided multiple ways, allowing the examination of reward division effects. Ten individuals were tested twice in 44 combinations of partners. Dyads with a high affiliation score attempted to cooperate more often and were also more often successful in doing so. Furthermore, dyads that shared rewards more equally seemed to be more likely to attempt cooperation in the next trial. Like other bird and some monkey species, but unlike, for example, chimpanzees, kea did not spontaneously show understanding of either the role of the partner or the mechanism behind the cooperation task. This may point to true disparities between species, but may also be due to differences in task design and/or the amount of exposure to similar tasks and individual skills of the subjects.     

Introduction to the Special Section: Toward Implementing Physiological Measures in Clinical Assessments of Adult Mental Health

This article serves as the introduction to the Special Section called “Toward Implementing Physiological Measures in Clinical Assessments of Adult Mental Health.” As such, it provides an overview of the importance of integrating assessments of physiological and subjective processes in mental health assessments and discusses the Research Domain Criteria (RDoC) initiative. In addition, it summarizes the findings from the four empirical studies published in the Special Section. Collectively, these studies sought to illustrate how physiological assessments can be incorporated in mental health assessments conducted in applied research and clinic settings. In all, we hope that this Special Section will inspire the type of interdisciplinary research spanning basic and applied work that will be critical to advancing the RDoC initiative.     

Sex differences in the assignment of responsibility for an accident

Two experiments examined the proposition that females assign less responsibility than males to a perpetrator in a feminine occupation and males assign less responsibility than females to a perpetrator in a masculine occupation. The results from Experiment 1 indicated that females assigned less responsibility than males to a perpetrator in a feminine occupation, whereas males and females assigned equal responsibility to a perpetrator in a masculine occupation. These results did not generalize to measures of causality, foreseeability, intent, or justification. Therefore, they suggest that responsibility may have been assigned on the basis of reliability of the perpetrator's behavior and that a measure of reliability may be more appropriate than a measure of responsibility. The results from Experiment 2 supported the contention. Females judged the behavior of a perpetrator in a feminine occupation to be more reliable than did males, and males judged the behavior of a perpetrator in a masculine occupation to be more reliable than did females.
