Are you looking at me? Eye gaze and person perception 总被引:4,自引:0,他引:4
Previous research has highlighted the pivotal role played by gaze detection and interpretation in the development of social cognition. Extending work of this kind, the present research investigated the effects of eye gaze on basic aspects of the person–perception process, namely, person construal and the extraction of category–related knowledge from semantic memory. It was anticipated that gaze direction would moderate the efficiency of the mental operations through which these social–cognitive products are generated. Specifically, eye gaze was expected to influence both the speed with which targets could be categorized as men and women and the rate at which associated stereotypic material could be accessed from semantic memory. The results of two experiments supported these predictions: Targets with nondeviated (i.e., direct) eye gaze elicited facilitated categorical responses. The implications of these findings for recent treatments of person perception are considered. 相似文献

On the ability of children with developmental coordination disorder (DCD) to inhibit response initiation: the simon effect 总被引:3,自引:0,他引:3
The ability of children with developmental coordination disorder (DCD) to inhibit the initiation of an incorrect manual response urge was examined using a typical Simon task. While the size of the Simon effect was the same for both DCD (N = 20) and Control (N = 20) groups of children, showing no difference with respect to the time needed to complete the inhibition an unwanted response, children with DCD produced significantly more errors of the type which reflected a reduced ability to successfully effect the inhibition operation when it was required. This result is consistent with some earlier findings pointing to an inhibitory deficit for children with DCD (Wilson & Maruff, 1999). 相似文献

The contribution of J. E. Helms's (1990) people of color racial identity model to the collective and individual self-esteem of Black Brazilian men (N = 203) was explored. The relationships between racial identity attitudes and other racial constructs such as skin color, racial group self-designation, and racial mistrust were also examined. Hierarchical regression analyses revealed that the set of racial identity attitudes (conformity, dissonance, resistance, and internalization) was significant in predicting self-esteem (collective and individual). Results from a multivariate analysis of variance showed an effect for skin color on racial attitudes. In addition, racial identity was significantly related to mistrust of Whites by Black Brazilian men. The implications of these findings are discussed in the context of racial relations in Brazil. 相似文献

Forgetting functions generated by delayed matching-to-sample procedures allow delay-dependent effects to be distinguished from delay-independent effects on working memory. Parameters of negative exponential functions estimate initial discriminability (intercept) and rate of forgetting (slope). Forgetting functions for patients with Alzheimer's disease indicate that they differ from normal controls in terms of reduced initial discriminability—that is, in the encoding component of memory performance— but not convincingly in rate of forgetting. Reanalyses of previous studies with different species suggest that pro- and anticholinergic drugs influence initial discriminability in delayed matching-to-sample performance, but not rate of forgetting. The results of our reanalyses are consistent with the conclusion that the cholinergic system plays a role in the encoding component of working memory and that this is the main characteristic of the memory deficit shown by patients with Alzheimer's disease. 相似文献

The aim of this research was to study the effect of 12-minute clinical death on innate and acquired behavior, biogenic amine concentration, and the composition and quantity of neural populations in specific brain regions of white rats. The study shows that in animals during the postresuscitation period with formal restoration of neurological status, there are changes in emotional reactivity, orientation-exploration reactions, impairment of learning and memory, decrease in exercise tolerance and pain sensitivity. These processes are accompanied by alterations in serotonin and norepinephrine levels in the frontal cerebral cortex, dopamine and serotonin levels in the striatum, certain biochemical indices in blood plasma and neural loss in the CA1 sector of the hippocampus and lateral portions of the cerebellum. 相似文献

Recently, there have been several reports of the neurophysiological correlates of language acquisition. These indicate that the infant's brain is able to discriminate different phonemes within the first 2 months of life, that knowledge about stress patterns and phonotactic rules is established between 5-12 months, and that phonotactic knowledge begins to interact with lexical-semantic processes between 12-14 months. Electrophysiological markers for lexical-semantic processes indicate that semantic processing of words in picture contexts is present at 14 months and for words in sentential contexts around 30 months. At 32 months, children demonstrate an adult-like electrophysiological response pattern to syntactic violations. The similarities between the brain response patterns observed in children and adults support the view that language develops in a continuous manner. 相似文献

Although both have been used in studies of the impact of mental illness on the family, the constructs of caregiver strain (often referred to as burden of care) and psychological distress have not been clearly distinguished. The vagueness surrounding these constructs, and the lack of a cohesive conceptual framework for understanding how they relate, leads to contradictory interpretations of results. This compromises the building of the knowledge base needed to develop and evaluate interventions to support families as they struggle to meet the needs of their children with emotional and behavioral challenges. We utilized the ABCX Model as a framework for understanding caregiver strain and its relationship to psychological distress. Structural equations modeling was used to test the hypothesized relationship between caregiver strain and psychological distress, as well as the role of key child and family variables. These included child symptoms, stressful life events, social support, family functioning, and material resources. Our findings indicated that caregiver strain and psychological distress, although related, have distinct correlates and different implications in the family context. 相似文献

In the present study the nature of stress and coping was investigated and considered as socially constructed. Thirty small group interviews were performed using the Critical Incident Technique in one female- and one male-dominated customer service department of a telecom company. The main themes about stress among both women and men were often expressed as collective phenomena and were connected to the organizational change and downsizing process, problems when carrying out the work and lack of autonomy. However, a striking difference between female and male interviews was found in the way that women to a greater extent expressed lack of autonomy and their working situation was described as strictly regulated. The findings illustrate that a traditional gender difference regarding autonomy could be found when comparing a female- and a male-dominated department even though they were performing the same type of job. Both women and men portrayed coping as a mixture of collective and individual strategies. They often mentioned collective acceptance, resignation and hardening. There is a need for further research about women and men at work, taking into consideration the interpersonal context and the collective nature of stress and coping. 相似文献
