Modeling geometric–optical illusions: A variational approach

Visual distortions of perceived lengths, angles, or forms, are generally known as “geometric–optical illusions” (goi). In the present paper we focus on a class of gois where the distortion of a straight line segment (the “target” stimulus) is induced by an array of non-intersecting curvilinear elements (“context” stimulus). Assuming local target–context interactions in a vector field representation of the context, we propose to model the perceptual distortion of the target as the solution to a minimization problem in the calculus of variations. We discuss properties of the solutions and reproduction of the respective form of the perceptual distortion for several types of contexts. Moreover, we draw a connection between the interactionist model of gois and Riemannian geometry: the context stimulus is understood as perturbing the geometry of the visual field from which the illusory distortion naturally arises. The approach is illustrated by data from a psychophysical experiment with nine subjects and six different contexts.     

Hemispheric asymmetry in cross-race face recognition

This study examines two phenomena related to face perception, both of which depend on experience and holistic processing: perceivers process faces more efficiently in the right hemisphere of the brain (a hemispheric asymmetry), and they typically show greater recognition accuracy for members of their racial ingroup (a cross-race recognition deficit). The current study tests the possibility that these two effects are related. If asymmetry depends on experience, it should be particularly evident with (more familiar) ingroup faces; if cross-race recognition relies on holistic processing, it should be particularly evident for faces presented to the right hemisphere. Black and White participants viewed Black and White faces presented to either the left or right visual field. As predicted, participants showed a more pronounced asymmetry for ingroup (rather than outgroup) faces, and cross-race recognition deficits were more pronounced for stimuli presented to the left (rather than the right) visual field.     

Stereotype threat: Antecedents and consequences for working women

Three studies investigated antecedents and consequences of stereotype threat for female employees. The results of Studies 1 and 2 suggest that social comparisons with men are associated with feelings of stereotype threat whereas social comparisons with women are not. Stereotype threat, in turn, was associated with conflict surrounding women's identity as female employees and with decreased perceived likelihood of achieving career goals. Study 3 extended these findings by demonstrating that feelings of stereotype threat are also negatively related to workplace attitudes and turnover intentions. Furthermore, the effect of stereotype threat on these job attitudes and intentions was itself mediated by identity conflict and perceived likelihood of achieving career goals. Implications and limitations of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Psychopathic personality as a distinctive indicator of severity and persistence for child and youth conduct problems

Conduct problems are among the most discussed behavioral problems during childhood and adolescence. Given their heterogeneity, in recent years, researchers on this topic have called for delineation of early-onset conduct problems on the basis of affective, interpersonal and behavioral traits that resemble adult psychopathy. The present study aims to analyze, from both a cross-sectional and longitudinal perspective, whether early psychopathic traits allow identification of a group of individuals defined by severe and persistent behavioral problems. To achieve this goal, data from a sample of 192 children (aged 6 to 11) were analyzed; from this sample, 133 children were followed-up in a new data collection that took place three years later. From the data obtained with the mCPS and CBCL (parents), and APSD and TRF (teachers), we observed that children who showed early psychopathic traits, also showed greater frequency, severity and persistence of conduct problems. These results suggest the need to take into account the role of psychopathic traits (particularly, affective and interpersonal) as risk factors to delimit the most serious and persistent patterns of externalizing behavior.

Intergenerational Coresidence and Life Satisfaction in Old Age: The Moderating Role of Homeownership

Household structure for older people’s subjective well-being is important to promote healthy ageing in the context of the rapid increase of the older population. Living with adult children is known to promote older people’s life satisfaction, a key indicator of subjective well-being, whereas others claim a negative impact of such intergenerational coresidence. This study aims to empirically test these theories (family support vs. family conflict), by examining the role of homeownership–another important factor contributing to subjective well-being–in this association between intergenerational coresidence and life satisfaction. Analysing the nationally representative data on the elderly population in South Korea, the findings showed that intergenerational coresidence decreases life satisfaction when the elderly achieve a certain level of housing security by living in owner-occupied housing. Living with adult children is negatively associated with life satisfaction particularly for older old homeowners compared to younger old owners. Our findings provide implications for public policies promoting intergenerational coresidence and asset-based welfare to enhance older people’s well-being in Korea and more broadly in East Asia.

     

Ambivalent Sexism and Religion: Connected Through Values

Sexist attitudes do not exist in a limbo; they are embedded in larger belief systems associated with specific hierarchies of values. In particular, manifestations of benevolent sexism (Glick and Fiske 1996, 1997, 2001) can be perceived as a social boon, not a social ill, both because they are experienced as positive, and because they reward behaviors that maintain social stability. One of the strongest social institutions that create and justify specific hierarchies of values is religion. In this paper, we examine how the values inherent in religious beliefs (perhaps inadvertently) propagate an unequal status quo between men and women through endorsement of ideologies linked to benevolent sexism. In a survey with a convenience sample of train passengers in Southern and Eastern Poland (N?=?180), we investigated the relationship between Catholic religiosity and sexist attitudes. In line with previous findings (Gaunt 2012; Glick et al. 2002a; Ta?demir and Sakall?-U?urlu 2010), results suggest that religiosity can be linked to endorsement of benevolent sexism. This relationship was mediated in our study by the values of conservatism and openness to change (Schwartz 1992): religious individuals appear to value the societal status quo, tradition, and conformity, which leads them to perceive women through the lens of traditional social roles. Adhering to the teachings of a religion that promotes family values in general seems to have as its byproduct an espousal of prejudicial attitudes toward specific members of the family.     

Differences in Emotional Labor Across Cultures: A Comparison of Chinese and U.S. Service Workers

Purpose

In the global economy, the need for understanding cross-cultural differences and the customer service-related processes involved in emotional labor is evident. The current study attempts to examine this issue by developing and testing hypotheses pertaining to cross-cultural differences between U.S. and Chinese service workers on the levels of display rule perceptions, emotion regulation, and burnout (i.e., emotional exhaustion, personal accomplishment, and depersonalization) as well as the relationships among these variables.

Design/Methodology/Approach

Data was collected from service workers in the U.S. (n = 280) and China (n = 231). We tested for measurement differences, mean differences, and differences in the relationships among emotional labor variables between the two samples using a variety of analyses.

Findings

It was found that the relatively robust sequence of display rules to surface acting to burnout was observed in a U.S. sample but was not observed in a Chinese sample, with some relationships being significantly weaker in the Chinese sample (e.g., surface acting to burnout dimensions) and others exhibiting relationships with the opposite sign (e.g., display rules were negatively related to surface acting in the Chinese sample).

Implications

The results of this study suggest that many of the relationships among emotional labor variables vary as a function of the cultural context under consideration.

Originality/Value

This is the first study to directly compare emotional labor across samples from Eastern and Western cultures. Additionally, this study begins to answer questions concerning why models of emotional labor generated in a Western culture may not apply in other cultures.     

Personality,Perceived Occupational Stressor,and Health-Related Quality of Life Among Chinese Judges

Personality is hypothesized to have direct and indirect effects on health-related quality of life (HRQoL) through the mediating role of perceived occupational stressors. This hypothesized model was tested with Chinese judges, individuals characterized by high occupational stress. In this cross-sectional study, 330 judges undergoing professional training at the Shandong Judge Training Institute completed questionnaires assessing their personality (Big Five Inventory, BFI), perceived occupational stressors (Occupational Role Questionnaire, ORQ), and HRQoL (Medical Outcomes Study Short-Form Health Survey, SF-36). The proposed model was tested using structural equation modelling (SEM) approaches. The SEM analysis showed a good fit of the data to the hypothesized model(x ²/df = 1.52, P?P?Neuroticism also had a negative indirect effect (?0.18, P?P?P?相似文献
