The study examined whether face‐specific perceptual brain mechanisms in 9‐month‐old infants are differentially sensitive to changes in individual facial features (eyes versus mouth) and whether sensitivity to such changes is related to infants' social and communicative skills. Infants viewed photographs of a smiling unfamiliar female face. On 30% of the trials, either the eyes or the mouth of that face were replaced by corresponding parts from a different female. Visual event‐related potentials were recorded to examine face‐sensitive brain responses. Results revealed that increased competence in expressive communication and interpersonal relationships was associated with a more mature response to faces, as reflected in a larger occipito‐temporal N290 with shorter latency. Both eye‐ and mouth changes were detected, though infants derived different information from these features. Eye changes had a greater impact on the face perception mechanisms and were not correlated with social or communication development, whereas mouth changes had a minimal impact on face processing but were associated with levels of language and communication understanding.

Emotion researchers often categorize angry and fearful face stimuli as "negative" or "threatening". Perception of fear and anger, however, appears to be mediated by dissociable neural circuitries and often elicit distinguishable behavioral responses. The authors sought to elucidate whether viewing anger and fear expressions produce dissociable psychophysiological responses (i.e., the startle reflex). The results of two experiments using different facial stimulus sets (representing anger, fear, neutral, and happy) indicated that viewing anger was associated with a significantly heightened startle response (p < .05) relative to viewing fear, happy, and neutral. This finding suggests that while anger and fear faces convey messages of "threat", their priming effect on startle circuitry differs. Thus, angry expressions, representing viewer-directed threat with an unambiguous source (i.e., the expresser), may more effectively induce a motivational propensity to withdraw or escape. The source of threat is comparatively less clear for fearful faces. The differential effects of these two facial threat signals on the defensive motivational system adds to growing literature highlighting the importance of distinguishing between emotional stimuli of similar valence, along lines of meaning and functional impact. 相似文献

Few genetically-informative studies have attempted to explicitly identify the shared environmental (i.e., those environmental influences that contribute to sibling similarity) factors now known to contribute to adolescent delinquency. The current study therefore examined whether the parent-child relationship served as one source of these shared environmental influences. Participants were 610 adoptive and biological families from the Sibling Interaction and Behavior Study (SIBS). Parents and adolescents reported on their parent-child conflict and parental involvement with child, and adolescents reported on their own delinquent behaviors. We employed structural equation modeling and supplementary multilevel modeling, finding consistent evidence that the association between delinquency and the parent-child relationship is at least partially shared environmental in origin. Such findings provide an important extension of previous twin studies, as they suggest that passive genotype-environment correlations do not explain earlier findings of shared environmental influences on this association. 相似文献

Three studies consider a basis for intergroup helping. Specifically, they show that group members may help others to disconfirm a stereotype of their own group as mean. Study 1 shows that Scots believe they are seen as mean by the English, resent this stereotype, are motivated to refute it, and believe out-group helping is a particularly effective way of doing so. Study 2 shows that increasing the salience of the English stereotype of the Scottish as mean leads Scots to accentuate the extent to which Scots are depicted as generous. Study 3 shows that increasing the salience of the stereotype of the Scots as mean results in an increase in the help volunteered to out-group members. These results highlight how strategic concerns may result in out-group helping. In turn, they underscore the point that helping others may be a means to advance a group's interest. 相似文献

The modulatory influence of literacy on the cognitive system of the human brain has been indicated in behavioral, neuroanatomic, and functional neuroimaging studies. In this study we explored the functional consequences of formal education and the acquisition of an alphabetic written language on two- and three-dimensional visual naming. The results show that illiterate subjects perform significantly worse on immediate naming of two-dimensional representations of common everyday objects compared to literate subjects, both in terms of accuracy and reaction times. In contrast, there was no significant difference when the subjects named the corresponding real objects. The results suggest that formal education and learning to read and to write modulate the cognitive process involved in processing two- but not three-dimensional representations of common everyday objects. Both the results of the reaction time and the error pattern analyses can be interpreted as indicating that the major influence of literacy affects the visual system or the interaction between the visual and the language systems. We suggest that the visual system in a wide sense and/or the interface between the visual and the language system are differently formatted in literate and illiterate subjects. In other words, we hypothesize that the pattern of interactions in the functional-anatomical networks subserving visual naming, that is, the interactions within and between the visual and language processing networks, differ in literate and illiterate subjects. 相似文献

Theoretical links between emotional knowledge and theory of mind (ToM) have previously been proposed. This study investigates this relationship using measures of both ability and trait emotional intelligence (EI). Our sample comprised 194 children, divided into two age groups (5–7 years and 8–10 years). Children participated in measures of false belief understanding, advanced tests of ToM, ability EI and trait EI, and a standardized language assessment. For both age groups, we found that only ability EI was related to false belief understanding. Furthermore, regression analyses revealed that the understanding and managing branches of ability EI predicted unique variance in false belief understanding once controlling for age, language, and the other ability EI branches. Trait EI failed to display any association with false belief understanding. Ability and trait EI were associated with more advanced ToM tasks undertaken only by the older sample. These results offer support for previous research that has found a relationship between emotion perception and labelling and ToM. They also provide new knowledge: (1) higher order emotional knowledge, measured by ability EI, is associated with advanced ToM; and (2) emotional self efficacy, as measured by trait EI, is also important in advanced ToM. Furthermore, they provide the first account of associations between standardized EI measures and ToM. 相似文献

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high‐quality supervisor–employee relationships. A full cross‐lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory. 相似文献

Nine monkeys took part in two experiments on visual learning and the effect of inferotemporal ablation. The first experiment contrasted lesion effects in two tasks given to separate groups of animals: serial visual reversal learning set with only two visual stimuli in use throughout the experiment, and discrimination learning set with a new pair of visual stimuli for each discrimination problem. Following inferotemporal ablation, the within-reversal learning rate recovered to the normal pre-operative level, while within-problem learning in discrimination learning set remained substantially impaired. This result suggests that inferotemporal ablation does not directly impair visual associative learning, but rather produces a defect in visual identification such that only a small set of familiar stimuli can be correctly identified and associated with reward. The second experiment replicated an earlier experiment in showing that monkeys with inferotemporal ablation could learn at a normal rate to choose between stimuli according to their spatial orientation. A relation between the two types of unimpaired visual learning in the operated animals was suggested and analogies with clinical syndromes were discussed. The experimental results were interpreted within a distributed-trace model of learning, and this interpretation was illustrated and supported by a computer simulation presented in the Appendix. 相似文献
