Human face perception is a finely tuned, specialized process. When comparing faces between species, therefore, it is essential to consider how people make these observational judgments. Comparing facial expressions may be particularly problematic, given that people tend to consider them categorically as emotional signals, which may affect how accurately specific details are processed. The bared-teeth display (BT), observed in most primates, has been proposed as a homologue of the human smile (J. A. R. A. M. van Hooff, 1972). In this study, judgments of similarity between BT displays of chimpanzees (Pan troglodytes) and human smiles varied in relation to perceived emotional valence. When a chimpanzee BT was interpreted as fearful, observers tended to underestimate the magnitude of the relationship between certain features (the extent of lip corner raise) and human smiles. These judgments may reflect the combined effects of categorical emotional perception, configural face processing, and perceptual organization in mental imagery and may demonstrate the advantages of using standardized observational methods in comparative facial expression research. 相似文献

ABSTRACT— There has been little research over the past few decades focusing on similarities and differences in the form and function of emotional signals in nonhuman primates, or whether these communication systems are homologous with those of humans. This is, in part, due to the fact that detailed and objective measurement tools to answer such questions have not been systematically developed for nonhuman primate research. Despite this, emotion research in humans has benefited for over 30 years from an objective, anatomically based facial-measurement tool: the Facial Action Coding System (FACS). In collaboration with other researchers, we have now developed a similar system for chimpanzees (ChimpFACS) and, in the process, have made exciting new discoveries regarding chimpanzees' perception and categorization of emotional facial expressions and similarities in the facial anatomy of chimpanzees and humans, and we have identified homologous facial movements in the two species. Investigating similarities and differences in primate emotional communication systems is essential if we are to understand unique evolutionary specializations among different species. 相似文献

Coping style is an important feature in the understanding of the relation between real-life stress and associated blood pressure (BP) responses. In this study, 10 high- and 10 low-"self-focused-coping" (SFC) male college students were tested with ambulatory BP monitoring on two typical schooldays, one of which included an examination. It was found that the high-SFC subjects, defined as those who tend to keep to themselves and/or blame themselves in stressful situations, showed higher BP responses than the low-SFC subjects, but only on the exam day. Further, the high-SFC subjects showed higher BP during the exam but also had BP elevations that were sustained during other activities throughout the same day, including evening rest. These results are discussed in terms of the relation between psychological and physiological responding. 相似文献

Twin children participating in a longitudinal study were observed at 9, 12, 18, 24, and 30 months of age in two settings: unstructured free play and relatively structured test taking. Behaviors relating to adaptability to the two settings were rated and the scores analyzed for evidence of continuity both across settings and across ages. Age-to-age correlations for the adaptability scores for each setting yielded a simplex pattern of low-moderate order. Correlations of individuals' scores across settings were also of low-moderate order. Within-pair correlations indicated that identical twins were more similar that same-sex fraternal twins in both settings, but correlations were consistently stronger in the playroom setting. Analysis of variance was performed to test for within-pair concordance in the direction and degree of change. Identical pairs remained significantly more similar in adaptability from one setting to another even when change in adaptability occurred. Similar results were found for change across ages; however, these differences were significant only in the playroom setting. Results suggest that situation variables contribute to the low stabilities frequently reported for personality dimensions but that the direction and degree of behavioral change are genetically conditioned. 相似文献

Recognition memory may be mediated by the retrieval of distinct types of information, notably, a general assessment of familiarity and the recovery of specific source information. A response-signal speed-accuracy trade-off variant of an exclusion procedure was used to isolate the retrieval time course for familiarity and source information. In 2 experiments, participants studied spoken and read lists (with various numbers of presentations) and then performed an exclusion task, judging an item as old only if it was in the heard list. Dual-process fits of the time course data indicated that familiarity information typically is retrieved before source information. The implications that these data have for models of recognition, including dual-process and global memory models, are discussed. 相似文献

Receptive foreign language proficiency is usually measured with reading and listening comprehension tasks. A novel approach to assess such proficiencies – viewing comprehension – is based on the presentation of short instructional videos followed by one or more comprehension questions concerning the preceding video stimulus. In order to evaluate a newly developed viewing comprehension test 485 German high school students completed reading, listening, and viewing comprehension tests, all measuring the receptive proficiency in English as a foreign language. Fluid and crystallized intelligence were measured as predictors of performance. Relative to traditional comprehension tasks, the viewing comprehension task has similar psychometric qualities. The three comprehension tests are very highly but not perfectly correlated with each other. Relations with fluid and crystallized intelligence show systematic differences between the three comprehension tasks. The high overlap between foreign language comprehension measures and between crystallized intelligence and language comprehension ability can be taken as support for a uni-dimensional interpretation. Implications for the assessment of language proficiency are discussed. 相似文献

Homelessness disrupts young people’s participation in the productive occupations that facilitate transition to adulthood, impairs social connections, and has a disorganizing effect on their time use. Semi-structured focus group interviews were used to explore how 19 homeless young people perceived their daily routines, meaningful occupations, and social participation to be impacted by the experience of homelessness. Occupational therapy practitioners can use the findings from this study to inform the development of comprehensive community-based programming aimed at increasing social opportunities, developing balanced, healthy routines, decreasing intrinsic and extrinsic barriers to residential stability, and promoting participation in productive and leisure occupations. 相似文献
