The purpose of this study was to assess the role of common motor responses as the "speaker" behavior on stimulus class formation, and the emergence of functional classes. Experiment 1 examined whether training one motor response to a set of three stimuli and a second motor response to another set of three stimuli would result in correct category-sort responses for 5 typically developing preschool children. Three of the children passed the categorization tests. Experiment 2 examined whether the classes formed in Experiment 1 were functional classes, and whether participants who did not pass categorization tests in Experiment 1 would do so following common vocal tact training. The 2 participants who failed categorization tests in Experiment 1 passed these tests in Experiment 2, although none of the participants passed the tests for functional classes. The results of the current study did not unequivocally support the naming hypothesis. Future research should therefore evaluate other possible sources of control that aid in stimulus categorization. 相似文献

A total of 81 toddlers (24-27 months of age) participated in a biobehavioral investigation of inhibitory control. Maternal report measures of inhibitory control were related to laboratory tasks assessing inhibitory abilities under conditions of conflict, delay, and compliance challenge as well as toddler verbal ability. In addition, unique variance in inhibitory control was explained by task-related changes in brain electrical activity at lateral frontal scalp sites as well as concurrent inhibitory task performance. Implications regarding neural correlates of executive function during early development and a central organizing role of inhibitory processing during toddlerhood are discussed. 相似文献

The role of habituation and attentional orienting in the disruption of short-term memory performance
A series of experiments explored habituation and dishabituation to repeated auditory distractors. Participants memorised lists
of visually presented items in silence or while ignoring continuously presented auditory distractors. No habituation could
be observed, in that the size of the auditory distractor effect did not decrease during the experiment. However, there was
evidence for attentional orienting when novel auditory material was presented after a long period of repetitive stimulation,
in that a change of distractors was associated with a temporary decrease in recall performance. The results are most consistent
with theoretical accounts that claim that the auditory distractor effect is caused primarily by automatic interference, but
that still allow attention to play a limited role in the short-term maintenance of information. 相似文献

Team mental models (TMMs) have received much attention as important drivers of effective team processes and performance. Less is known about the factors that give rise to these shared cognitive structures. We examined potential antecedents of TMMs, with a specific focus on team composition variables, including various facets of personality and surface-level diversity. Further, we examined implicit coordination as an important outcome of TMMs. Results suggest that team composition in terms of the cooperation facet of agreeableness and racial diversity were significantly related to team-focused TMM similarity. TMM similarity was also positively predictive of implicit coordination, which mediated the relationship between TMM similarity and team performance. Post hoc analyses revealed a significant interaction between the trust facet of agreeableness and racial diversity in predicting TMM similarity. Results are discussed in terms of facilitating the emergence of TMMs and corresponding implications for team-related human resource practices. 相似文献

Harries and Stadler (1988) observed only a positive linear trend, with no curvilinear relationship, between heat and violence in their 1980–81 Dallas field data. When Cotton (1986) observed similar trends in his data, we noted that in fact the variance in violence increases with temperature (Bell & Fusco, 1986). We report here similar statistically significant heteroscedasticity in the Harries and Stadler data. We propose that both aggressive and escape tendencies increase with high ambient temperatures, such that in some circumstances aggression will decline under very hot and uncomfortable conditions. We conclude that the negative affect escape model of the temperature-aggression relationship is neither dead cold nor hot and bothered. 相似文献

When witnesses at a trial offer testimony that is vivid, it may be more persuasive than the same testimony offered in a pallid manner. In this paper we elucidate three categories of variables (inferential, attentional/memorial, and affective) that are likely to mediate the effects of the vividness of testimony on jury judgments. These variables are then used to explain discrepant findings among mock juror experiments investigating vividness effects. Finally, we discuss the implications of vividness effects for the legal system. 相似文献

This study sought to find out how much total knowledge adolescents had concerning AIDS, what particular areas of knowledge were deficient, and how those areas might be related to attitudes and experiences in their social world. Seventy-eight adolescent males from one suburban and three urban high schools were interviewed. A 101-item questionnaire was used to assess: a) overall knowledge about AIDS; b) attitudes about sexuality, drugs, death, and AIDS and; c) related aspects of their social world, i.e., number of IV drug users known, and sources of information about AIDS. Analyses of variance were performed on overall knowledge of AIDS and on five content areas of knowledge. Race was shown to relate to significant differences in the knowledge scores. The social world associated with the urban samples were discussed as risk factors for minority youth. Different attitudes related to strengths and weaknesses in different areas of knowledge. Attitudes associated with deficiencies in different subareas of knowledge were discussed as additional risk factors and as presenting target areas for AIDS education efforts. 相似文献
