Affect, personality, and facial expressive characteristics of older people   总被引:1,自引:0,他引:1  
This study explored the relationship between emotion-based personality traits and expressive patterns in older subjects. Specifically, the study sought to demonstrate (a) that individuals have emotion expression biases, as revealed by structural and dynamic properties of the face, and (b) that there is a link between facial characteristics (as indexed by the judgments of trained and naive raters) and personality traits. An encoding/decoding paradigm was used; 30 adult, naive judges rated five emotion-pose photographs for each of 14 older subjects who had also completed a personality trait measure. Results indicated that individuals vary in their ability to accurately encode emotion states and that these patterns are linked to personality traits in an affect-specific way. The results are discussed within the framework of Darwinian theory and Plutchik's model of personality.  相似文献

Elderly subjects were 41% less accurate than young subjects in localizing a point in the frontal plane. The decline could be ascribed neither to an age difference in image formation or skill acquisition nor to a difference in motivational level or trace retention. Evidently the "ambient" or "transient" visual system is compromised at an elementary level. Reasons why this deficit may not be compounded at more complex levels of spatial processing are suggested.  相似文献

The purpose of this article is to encourage behavior analysts to expand their domain of interest and application to include the "social/political" contingencies that are developed and implemented by policymakers and lawmakers. Using the Vermont juvenile justice system as a prototype, examples are provided that focus on the tertiary, secondary, and primary prevention of delinquent behavior.  相似文献

With a sample of 18 capital cases tried in Kentucky, South Carolina, and California, we attempted to replicate an earlier study which showed that significantly more defense challenges for cause were granted under conditions of sequestered, individual voir dire than when voir dire was conducted under less enhanced conditions. In the current sample, sequestered, individual voir dire again resulted in more defense removals for cause than obtained with less extensive voir dire. We present data on the defense removals for cause partitioned into five categories according to the reason for the challenge and analyze the effects of jury selection consultants on the various indices of voir dire as well as final sentence.  相似文献

To evaluate expectations derived from ego-identity theory and symbolic-interaction theories about the association between self-concept and peer-group affiliations in adolescence, we examined the self-esteem of 221 7th through 12th graders associated by peers with one of five major school crowds and 106 students relatively unknown by classmates and not associated with any school crowd. Among crowd members, self-esteem was directly related to the position of one's crowd in the peer-group status hierarchy (based on both peer-rated and self-perceived crowd affiliation). Outsiders' self-esteem differed in relation to the accuracy of their reflected appraisal of and the salience they attached to crowd affiliation. Crowd members as a whole exhibited higher self-esteem than outsiders as a whole. Differences, however, were mediated by crowd status, salience of crowd affiliation, and the accuracy of reflected appraisals. An adequate interpretation of the findings required an integration of Festinger's (1954, 1957) social comparisons and cognitive-dissonance theories, Cooley's (1902) notions of reflected appraisal, and Newman and Newman's (1976) extrapolations from ego-identity theory.  相似文献
