Asymmetric dependencies in perceiving identity and emotion: experiments with morphed faces. 总被引:4,自引:0,他引:4
We investigated whether an asymmetric relationship between the perception of identity and emotional expressions in faces (Schweinberger & Soukup, 1998) may be related to differences in the relative processing speed of identity and expression information. Stimulus faces were morphed across identity within a given emotional expression, or were morphed across emotion within a given identity. In Experiment 1, consistent classifications of these images were demonstrated across a wide range of morphing, with only a relatively narrow category boundary. At the same time, classification reaction times (RTs) reflected the increased perceptual difficulty of the morphed images. In Experiment 2, we investigated the effects of variations in the irrelevant dimension on judgments of faces with respect to a relevant dimension, using a Garner-type speeded classification task. RTs for expression classifications were strongly influenced by irrelevant identity information. In contrast, RTs for identity classifications were unaffected by irrelevant expression information, and this held even for stimuli in which identity was more difficult and slower to discriminate than expression. This suggests that differences in processing speed cannot account for the asymmetric relationship between identity and emotion perception. Theoretical accounts proposing independence of identity and emotion perception are discussed in the light of these findings. 相似文献

In considering the influences of microsystems on adolescent substance use, familial and peer contexts have received the most extensive attention in the research literature. School and neighborhood settings, however, are other developmental contexts that may exert specific influences on adolescent substance use. In many instances, school settings are organized to provide educational services to students who share similar educational abilities and behavioral repertoires. The resulting segregation of students into these settings may result in different school norms for substance use. Similarly, neighborhood resources, including models for substance use and drug sales involvement, may play an important role in adolescent substance use. We briefly review literature examining contextual influences on adolescent substance use, and present results from two preliminary studies examining the contribution of school and neighborhood context to adolescent substance use. In the first investigation, we examine the impact of familial, peer, and school contexts on adolescent substance use. Respondents were 283 students (ages 13 to 18) from regular and special education classrooms in six schools. Although peer and parental contexts were important predictors of substance use, school norms for drug use accounted for variance in adolescent use beyond that explained by peer and parental norms. Data from a second study of 114 adolescents (mean age = 15) examines neighborhood contributions to adolescent substance use. In this sample, neighborhood indices did not contribute to our understanding of adolescent substance use. Implications for prevention are presented. 相似文献

In two experiments, item-specific transfer was examined in simple multiplication and division with prime and probe problems separated by four to six trials. As was predicted by Rickard and Bourne's (1996) identical-elements model, response time (RT) savings were larger with identical (e.g., prime 63 divided by 7, probe 63 divided by 7) than with inverted (63 divided by 9 and 63 divided by 7) division problems, whereas identical (7 x 9 and 7 x 9) and inverted (9 x 7 and 7 x 9) multiplication problems produced equivalent transfer. Nonetheless, there was statistically significant transfer between inverted division problems. Furthermore, RT savings in the multiplication-to-division transfer conditions (e.g., prime 7 x 9, probe 63 divided by 7) indicated that multiplication mediated large-number division problems. These latter effects are not predicted by the identical-elements model but may be reconciled with the model by distinguishing associative transfer (facilitation owing to strengthening of a common problem node in memory) from mediated transfer (facilitation owing to mediation by a strengthened, related problem). Skilled adults can exploit the conceptual correspondences between multiplication and division facts in a highly efficient way to facilitate performance. 相似文献

This study provides a cross-sectional analysis of the relations between group self-identification and adolescent drug use in 3 samples of youth: comprehensive high-school, continuation high-school, and runaway/street youth. Youth identified with discrete groups in all 3 samples, and similar general groups were formed. In most comparisons, a high-risk group showed greater levels of drug use than did other groups. This is the first study to demonstrate that group self-identification (a) is a generalizable construct across different types of adolescent samples, (b) is related to use of drugs other than tobacco, and (c) remains a significant correlate of drug use controlling for its relations with demographic variables and several other psychosocial variables. 相似文献

Purpose
We examine how supervisor stress is associated with employee-rated abusive supervision. In addition, we test the premise that higher levels of physical exercise by supervisors can buffer the negative effects of stress on their relationship with their subordinates.Design/Methodology/Approach
A matched sample of 98 employed individuals and their direct supervisors was used to test our hypotheses.Findings
Results suggest that increased levels of supervisor-reported stress are related to the increased experience of employee-rated abusive supervision. We also find that the relationship between supervisor stress and abusive behavior can be diminished when supervisors engage in moderate levels of physical exercise.Implications
While the current economic conditions and a host of other trying workplace factors mean that supervisors are likely to experience workplace stress, we found evidence that they do not necessarily have to transfer these frustrations onto those they supervise. Our study supports a link between supervisor stress and employee perceptions of abusive supervision, but this is a link that can be loosened if supervisors engage in moderate levels of physical exercise.Originality/Value
The results of this study add to the modest number of antecedents to abusive supervision that have been discovered in existing research. In addition, this is the first study to examine how exercise can buffer the relationship between supervisor stress and employee perceptions of abusive supervision. 相似文献56.

There are websites where individuals anonymously provide informal reviews of professors. What impact do such sites have on student and professor motivational factors? Research suggests that undergraduate students are affected (e.g. Edwards et?al. in J Comput Mediat Commun 14:368?C392, 2009; Kowai-Bell et?al. in Comput Hum Behav 27(5):1862?C1867, 2011). The goals of the present investigation are to (1) see if Master??s level students are also influenced and (2) investigate how professors are affected. We provided students (Study 1) and professors (Study 2) comments from an informal review website and they, respectively, took the perspective of a potential student or the professor described in the comments. In Study 1, consistent with prior research on undergraduates, Master??s level students were affected by the reviews (perceived control, outcome expectancies, affect toward taking the class, and likelihood of recommending to a friend), in accordance with the valence of the reviews. Among professors (Study 2), the valence of the reviews influenced affect and self-concept with respect to relational aspects of teaching (mood, affect toward teaching again, confidence that students liked them, and confidence that they would have rapport with future students) but did not have an effect on professor self-concept with respect to competence (teaching ability and teaching well in the future). Furthermore, preliminary evidence suggests that new professors are more susceptible than experienced professors. The results of these studies are relevant because of the degree to which students and instructors contribute to the socioemotional climate of the classroom (Frenzel et?al. in J Educ Psychol 103(3):705?C716, 2009; Radel et?al. in J Educ Psychol 102(3):577?C587, 2010). 相似文献

Self-stigma is a barrier to the recovery of persons with schizophrenia. Little is known about whether participation in rehabilitation is naturalistically linked to declines in self-stigma, and if so, what is correlated with changes in self-stigma. The current study examined in a quasi-experimental design the rate of change of self-stigma and whether changes were correlated with self-esteem, positive symptoms, and emotional distress for persons enrolled in rehabilitation. Symptoms were measured using the Positive and Negative Syndrome Scale (Kay, Fizsbein, & Opler, 1987), self-esteem was measured with the Multidimensional Self-Esteem Inventory (Lysaker, Ringer, & Davis, 2008), and self-stigma was assessed using the Internalized Stigma of Mental Illness Scale (Ritsher, Otilingam, & Grajales, 2003). Seventy persons with schizophrenia who worked at least one month in a vocational rehabilitation program were assessed on all measures at baseline and five months later. Results indicated a 25% decrease in self-stigma for 38% of the sample; these individuals tended to have less emotional distress both at baseline and follow-up, and had higher levels of self-esteem at follow-up. No differences in positive symptoms were found for groups whose stigma did or did not decrease. Results suggest that decreases in self-stigma may be correlated with increased self-esteem, while higher levels of emotional distress may be a barrier to stigma reduction. 相似文献

Drawing from terror management theory, the present research examined whether people turn to close relationships to manage the awareness of mortality because they serve as a source of perceived regard. Studies 1 and 2 demonstrated that mortality salience (MS) leads people to exaggerate how positively their romantic partners see them and demonstrated that people are more committed to their partners to the extent that their romantic partners serve as a source of perceived regard after MS (Study 3). Study 4 revealed that activating thoughts of perceived regard from a partner in response to MS reduced death-thought accessibility. Studies 5 and 6 demonstrated that MS led high relationship contingent self-esteem individuals to exaggerate perceived regard from a partner, and this heightened regard led to greater commitment to one's partner. Study 7 examined attachment style differences and found that after MS, anxious individuals exaggerated how positively their parents see them, whereas secure individuals exaggerated how positively their romantic partners see them. Together, the present results suggest that perceptions of regard play an important role in why people pursue close relationships in the face of existential concerns. 相似文献

Retrieval-induced forgetting (RIF) is a widely studied phenomenon of human memory, but RIF of arithmetic facts remains relatively unexplored. In 2 experiments, we investigated RIF of simple addition facts (2 + 3 = 5) from practice of their multiplication counterparts (2 × 3 = 6). In both experiments, robust RIF expressed in response times occurred only for high-strength small-number addition facts with sums ≤ 10, indicating that RIF from multiplication practice was interference dependent. RIF of addition-fact memory was produced by multiplication retrieval (2 × 3 = ?) but not multiplication study (2 × 3 = 6), supporting an inhibitory mechanism of RIF in arithmetic memory. Finally, RIF occurred with multiplication practiced in word format (three × four) and addition tested later in digit format (3 + 4), which provides evidence that digit and written-word formats for arithmetic accessed a common semantic retrieval network. The results support the view that addition and multiplication facts are stored in an interrelated semantic network and that RIF of competing addition facts is an intrinsic process of multiplication fact retrieval. 相似文献

From the perspective of terror management theory, awareness of death induces a need for validation of important values. Thus, for women who place a high value on their appearance (e.g., high self-objectifiers), mortality salience should increase positive reactions to objectifying experiences relative to women who do not highly value appearance. Two studies supported this hypothesis. Self-objectification moderated favorable reactions to objectifying stimuli (Study 1) and state self-esteem in response to an objectifying comment (Study 2) when women were primed with death. Together, the studies illustrate the complexity of reactions to objectification and, by highlighting conditions in which objectification serves a psychological function, help to explain the pervasiveness of the phenomena. 相似文献
