We are reviewing the recent findings on the Other Race Effect (ORE), which is the difficulty to recognize faces from other race compared to own race faces. Several hypotheses were proposed: negative attitude (Brigham and Malpass, 1985), attentional mechanisms (Chance and Goldstein, 1981), and the contact hypothesis (Brigham et al., 1982) which postulates that the ORE is due to a lack of experience with other race's faces. The contact hypothesis being, of course, modulated by attention and attitude. Valentine (1991 ; Valentine and Endo, 1992) proposes a norm-based coding model in which faces are encoded as vectors according to their deviation from a prototypical average. The resulting dimensions will differ according to the input received with certain salient, individuating dimensions carrying more “weight” than others. Predominant exposure to faces of a specific species, gender, or race early in life will cause the dimensions of one's prototype to become “tuned” towards such faces. The evidence presented support Valentine's model but we are showing that the quality of the contact is crucial in the experience. We are arguing that a developmental approach is necessary to better understand the ORE. Infants are able to process and recognize faces from an early age and several recent studies have found that the ORE can be observed from 9-10 months of age. Experimental results indicate that 6- to 9-months of age represents an important time of transition in the face processing system. If a certain type of face (other races) is not experienced prior to this period, then we appear to lose our ability to discriminate between individual faces within those groups. 相似文献

In this paper, we contrast the value‐belief‐norm (VBN) model and the theory of planned behavior (TPB) for the first time regarding their ability to explain conservation behavior. The participants represent a convenience sample of 468 university students. Using survey data and adopting previously established compound measures, structural equation analyses revealed a remarkable explanatory power for both theories: TPB's intention accounted for 95% of people's conservation behavior and VBN's personal norms accounted for 64%. Compared to the VBN model, the TPB covered its concepts more fully in terms of proportions of explained variance. More importantly, the fit statistics revealed that only the TPB depicts the relations among its concepts appropriately, whereas the VBN model does not. 相似文献

We report on a study of the influence of aging pathways on the evolution of solute-rich features in peak-aged Al-Mg-Si-Cu alloys. The concentration and partitioning ratios of Mg, Si and Cu and Mg/Si ratios in the heterogeneous solute-rich features all increase with increasing size, with Si exhibiting the highest partitioning ratio, but notably these ratios change dramatically depending on the aging pathway selected. Accordingly, the short-time age hardening response can be enhanced by promoting both homogeneous and heterogeneous precipitate nucleation, while simultaneous improvements in peak-aged strength and elongation can be attained by a vacancy-assisted aging pathway. 相似文献

Accurate social perception depends on many factors, including the extent to which perceivers hold correct beliefs about how behaviors reflect the characteristic being judged. In Study 1, target participants recorded videos introducing themselves to either a gay or straight student who was ostensibly in another room. Unbeknownst to the targets, the other student was illusory and not real. Analysis of the targets’ videos revealed that they behaved more positively toward the gay than straight student. Two subsequent studies demonstrated that new perceivers were below chance in guessing the illusory student’s sexual orientation from watching the male targets’ behavior, presumably because they expected to see negative behavior toward the gay illusory student. The study documents processes whereby social perception can go awry. 相似文献

The authors present a content analysis of syllabi from introductory multicultural counseling training (MCT) courses. Results suggest that these courses focus on knowledge of other cultural groups, emphasize the cultural identity exploration of the student at a lower level of training, and almost completely ignore the development of skills. The study revealed that MCT frequently includes groups beyond racial and ethnic minority groups. A broad range of instructional strategies are used, with a handful being used on a frequent basis. Los autores presentan un análisis del contenido de planes de estudios empleados en cursos introductorios de formación en consejería multicultural (MCT, por sus siglas en inglés). Los resultados sugieren que estos cursos se centran en el conocimiento de otros grupos culturales, enfatizan la exploración de la identidad cultural del alumno en los niveles iniciales de su formación e ignoran casi por completo el desarrollo de habilidades. El estudio reveló que la MCT incluye con frecuencia grupos aparte de las minorías raciales y étnicas. Se utiliza una amplia gama de estrategias didácticas, un puñado de las cuales se emplea frecuentemente. 相似文献

A dual-process approach to health risk decision making: The prototype willingness model 总被引:1,自引:0,他引:1

Although dual-process models in cognitive, personality, and social psychology have stimulated a large body of research about analytic and heuristic modes of decision making, these models have seldom been applied to the study of adolescent risk behaviors. In addition, the developmental course of these two kinds of information processing, and their relation to the development of self-regulation are not well understood at this time. The current paper reviews what leading dual-process models have to say about the development of analytic and heuristic decision making, and their implications for adolescent risk behavior. In addition, it reviews research on the prototype willingness model of adolescent decision making—a dual-process model designed specifically to address non-intentional, but volitional adolescent risk behavior. It also discusses the implications of dual-process models for intervention research. 相似文献

A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic.
A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric
explanation of Einstein’s famous E = mc
2. The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is
also investigated. 相似文献

This study examined correlates of academic procrastination and students’ grade goals in a sample of 226 undergraduates from
Singapore. Findings indicated that self-efficacy for self-regulated learning was significantly and negatively related to procrastination.
High self-efficacy for self-regulated learning also predicted students’ expectations of doing well and low self-efficacy for
self-regulated learning predicted students’ expectations of not doing well academically. Additionally, help-seeking predicted
students’ expectations of doing well academically while academic stress predicted students’ expectations of not doing well
academically. Implications for education and educational practice were discussed.

One hundred and thirty-one adults belonging to four age groups (19-26, 50-59, 60-69 and 70-82 years) performed a spatial stimulus-response consistency task in which the response dimension (left or right) overlapped relevant and irrelevant stimulus dimensions. The influence of the irrelevant stimulus dimension on response time was significantly greater in the middle age groups than among 19-26 year-olds, and significantly greater in the highest age group than in any other. This pattern persisted when allowance was made for a significant age-related increase in processing time (measured as reaction time in a single-stimulus, single-response task). It is concluded that in tasks of the kind used, the elderly resist interference from the irrelevant information less easily than do younger persons. Interestingly, comparison of Vincentized quintiles suggested that the effect of the irrelevant stimulus dimension decreased with increasing response time among 19-26 year-olds, but increased with response time among 70-82 year-olds. 相似文献

The Multidimensional Inventory of Black Identity--Teen (MIBI--T) is designed to assess the 3 cross-situationally stable dimensions (centrality, regard, and ideology) of the Multidimensional Model of Racial Identity (MMRI; R. M. Sellers, M. A. Smith, J. N. Shelton, S. A. J. Rowley, & T. M. Chavous, 1998) within teenagers. Adolescent responses (n= 489) to the MIBI--T were subjected to several analyses to evaluate the psychometric character of the measure. Findings indicated that the MIBI--T represents a valid framework for African American adolescents. Its internal structure is consistent with the conceptual framework of the MMRI, and findings support its construct validity. Results also indicate model invariance across grade level and gender, as well as suggest evidence of predictive validity. Further information about the MIBI--T and the full set of items are presented. 相似文献
