The capability of the human brain for Bayesian inference was assessed by manipulating probabilistic contingencies in an urn-ball task. Event-related potentials (ERPs) were recorded in response to stimuli that differed in their relative frequency of occurrence (.18 to .82). A veraged ERPs with sufficient signal-to-noise ratio (relative frequency of occurrence > .5) were used for further analysis. Research hypotheses about relationships between probabilistic contingencies and ERP amplitude variations were formalized as (in-)equality constrained hypotheses. Conducting Bayesian model comparisons, we found that manipulations of prior probabilities and likelihoods were associated with separately modifiable and distinct ERP responses. P3a amplitudes were sensitive to the degree of prior certainty such that higher prior probabilities were related to larger frontally distributed P3a waves. P3b amplitudes were sensitive to the degree of likelihood certainty such that lower likelihoods were associated with larger parietally distributed P3b waves. These ERP data suggest that these antecedents of Bayesian inference (prior probabilities and likelihoods) are coded by the human brain. 相似文献

Mentally representing action in terms of abstract goals rather than concrete procedures has been found to facilitate self-regulation, including meeting health goals. The present research examined whether autonomous motivation mediates the association between abstract thinking and health behavior engagement. We hypothesized that abstract (vs. concrete) thinking relates to viewing oneself as behaving autonomously, which, in turn, is positively associated with engaging in health behaviors. Two studies tested whether abstract thinking is associated with greater health behavior engagement and whether autonomous motivation statistically mediates this association. In Study 1, abstract thinking was associated positively with physical activity and fruit and vegetable intake. In Study 2, supporting pre-registered hypotheses, there was a significant indirect effect of abstract thinking on vigorous physical activity and fruit and vegetable intake through autonomous motivation. Whereas past research has emphasized that abstract thinking orients attention towards the value of broader goals, this research establishes that autonomous motivation helps explain associations between abstract thinking and health behavior engagement. 相似文献

The purpose of this study was to evaluate the role of prosocial behaviour against aggression in a school-based universal intervention adapted in two different (non-Western) countries, Colombia and Chile. Using a randomised pretest–post-test design (and controlling for participants' gender and parents' level of education), current results highlighted different effects of a similar programme in both sites. First, the school-based universal programme designed for promoting prosocial behaviours in the peer context obtained a positive cross-national effect on prosocial behaviour rated by three informants (i.e. self, peer and teacher reports). In Colombia, this effect was moderated by the initial level of prosociality of the participants and their level of education. Mediational two-wave model corroborated that the improvement on prosocial behaviours in both countries (moderated in the case of Colombia) predicted significantly lower level of physical aggression. Characteristics of the implementation considering different cultural and historical backgrounds were discussed. 相似文献

In the paper we obtain a new characterization of the BCK-algebras which are subdirect product of BCK-chains. We give an axiomatic algebraizable extension of the BCK-calculus, by means of a recursively enumerable set of axioms, such that its equivalent algebraic semantics is definitionally equivalent to the quasivariety of BCK-algebras generated by the BCK-chains. We propose the concept of "linearization of a system" and we give some examples. 相似文献

The decision-making performance of 20 married and 20 synthetic couples, all college students, was compared using the Ferreira-Winter Questionnaire technique. Married couples showed (a) greater spontaneous agreement with each other prior to conjoint discussion, (b) less politeness, (c) more intrusive interruptions, and (d) a lesser exchange of explicit information between husband and wife. Although married couples arrived at more "democratic" or representative decisions in a faster time, this was due to their greater degree of prior shared values and interests. The effects of the history and context of the relationship between subjects upon their pattern of communication and possible contrasts between normal and abnormal couples are discussed. 相似文献

Different patterns of dissociation in unilateral spatial neglect 总被引:3,自引:0,他引:3

The aim of this paper is to discuss the issue of dissociations found in unilateral spatial neglect according to the modality of space exploration and the nature of the task. For this purpose we present a reanalysis of the data from a recent paper of Gentilini et al. (1989) comparing visual and blindfolded exploration of a computer keyboard and discuss the performance of a left-brain-damaged patient with right visuospatial neglect and left-sided neglect dyslexia. We conclude that unilateral spatial neglect cannot be interpreted as a disruption of a single attentional mechanism, but rather it reflects impaired attentional mechanisms at several levels of cognitive processing. 相似文献
