Culture and Cognitive Development   总被引:3,自引:0,他引:3  
Human beings are biologically adapted for culture in ways that other primates are not. The difference can be clearly seen when the social learning skills of humans and their nearest primate relatives are systematically compared. The human adaptation for culture begins to make itself manifest in human ontogeny at around 1 year of age as human infants come to understand other persons as intentional agents like the self and so engage in joint attentional interactions with them. This understanding then enables young children (a) to employ some uniquely powerful forms of cultural learning to acquire the accumulated wisdom of their cultures, especially as embodied in language, and also (b) to comprehend their worlds in some uniquely powerful ways involving perspectivally based symbolic representations.  相似文献

Estrogen and Neural Plasticity   总被引:3,自引:0,他引:3  
Converging clinical evidence suggests that postmenopausal estrogen therapy in women is associated with improved cognition and a reduced incidence of Alzheimer's disease. In experimental work, investigators have found estrogen to promote changes in synaptic plasticity within the nervous system. In this article, we review both the clinical and the experimental literature, and consider mechanisms of action of estrogen on neurons and synaptic plasticity, and how they might protect against the cognitive impairments of old age.  相似文献

Much ink has been spilled on the claim that morality and religion have evolutionary roots. While some attempt to reduce morality and religion to biological considerations, others reject any link whatsoever. Any full account, however, must acknowledge the biological roots of human behavior while at the same time recognizing that our relatively unique capacity as cognitive agents requires orienting concepts of cosmic and human nature. While other organisms display quasi-moral and proto-moral behavior that is indeed relevant, fully moral behavior is only possible for organisms that attain a higher level of cognitive ability. This, in turn, implies a significant role for religion, which has traditionally provided an orientation within which moral conduct is understood.  相似文献

ABSTRACT

The aim of this study was to examine the relationship between muscular fitness and motor competence and processing speed in preschool children. Eighty-four preschool-aged children were recruited and underwent assessments for muscular fitness (muscular endurance and power), motor competence, and then participated in an auditory oddball task. The findings showed that muscular fitness and motor competence were associated with shorter reaction times after controlling for confounding factors. These findings provide tentative support for a positive association between muscular fitness and motor competence and processing speed in preschool children.

Little is known about the cognition of deception (Gombos, 2006). We propose a cognitive account of serious lying (i.e., deception involving high stakes) in response to a solicitation of a truth: Activation-Decision-Construction-Action Theory (ADCAT). Built on the Activation-Decision-Construction Model of answering questions deceptively (Walczyk, Roper, Seeman, & Humphrey, 2003), the theory elaborates on the roles of executive processes, theory of mind, emotions, motivation, specifies cognitive processing thoroughly, and considers the rehearsal of lies. ADCAT's four processing components are (a) activation of the truth, the (b) decision whether and how to alter deceptively the information shared, (c) construction of a deception, and (d) action [acting sincere while delivering a lie]. Core constructs are “theory of mind” and “cognitive resources”. Specifically, throughout serious deception, individuals are inferring the current or potential mental states of targets and taking steps to minimize the allocation of cognitive resources during delivery to appear honest and lie well.  相似文献

It has often been claimed that to demonstrate transitive inference is to demonstrate a logical ability, and by implication that transitivity as a property is generally a logical entity. Both claims are considered using a theoretically driven analysis together with consideration of relevant existing experimental research and some newly reported findings. This approach suggests an account of transitivity and transitive inferential reasoning that differs not only from the classic Piagetian account, but also from the information processing account so dominant today. We begin by considering one important issue, that the “logical” definitional criterion can only be approached if individuals are required to demonstrate a capacity for transitive inference that is discriminative in nature. This, together with interpretation of findings from existing transitive tasks, leads to the postulate of a three-component psychological system, with the components relying on perceptual, linguistic, and conceptual subprocesses and sensitivity to simple cues. The framework is testable and accommodates important aspects of classic and modern accounts of “transitive development” that until now have been taken to be mutually exclusive. It also readily accommodates both human and nonhuman research, yet neither a formal logical structure nor memory in any general sense need be assigned the primary role.  相似文献

Data regarding the relationship between self-efficacy and social behavior are limited, and questions remain about how to interpret the relationship of self-efficacy to phobic behavior in general. The current study includes data regarding the relationship between self-efficacy ratings and social behavior. The data also allow tests of an alternative hypothesis that self-efficacy ratings represent a general prediction regarding the likely outcome regarding a task. If this hypothesis is correct, the relationship of self-efficacy to behavior should be moderated by task familiarity. The study involved 124 socially anxious participants who gave at least partial data on a variety of measures, including three speaking tasks. In accordance with the alternative hypothesis, self-efficacy ratings best predicted behavior in reference to a familiar speaking task. Overall, self-efficacy showed only a moderate tendency to predict behavior.  相似文献
