性激素对人类择偶偏好的影响

择偶是一种重要的心理、社会和文化现象,婚恋择偶除了会受当下社会文化习俗等人文因素的影响,也受到个体生理机制的影响。本文聚焦热点,从进化心理学的角度阐述性激素对人类择偶偏好的影响。女性的择偶偏好受生理周期激素变化的影响,男性的择偶则会因为体内睾酮含量的不同而发生变化。性激素不仅影响人的心理和行为,还会影响人类择偶决策的神经机制。未来的相关研究应关注生理周期的测定方法、被试的文化背景和个体间的差异等。     

Intensity dependence in high-level facial expression adaptation aftereffect

Perception of a facial expression can be altered or biased by a prolonged viewing of other facial expressions, known as the facial expression adaptation aftereffect (FEAA). Recent studies using antiexpressions have demonstrated a monotonic relation between the magnitude of the FEAA and adaptor extremity, suggesting that facial expressions are opponent coded and represented continuously from one expression to its antiexpression. However, it is unclear whether the opponent-coding scheme can account for the FEAA between two facial expressions. In the current study, we demonstrated that the magnitude of the FEAA between two facial expressions increased monotonically as a function of the intensity of adapting facial expressions, consistent with the predictions based on the opponent-coding model. Further, the monotonic increase in the FEAA occurred even when the intensity of an adapting face was too weak for its expression to be recognized. These results together suggest that multiple facial expressions are encoded and represented by balanced activity of neural populations tuned to different facial expressions.     

Social capital and PTSD among PLWHA in China: the mediating role of resilience and internalized stigma

Post-traumatic Stress Disorder (PTSD) is frequent among people living with HIV/AIDS (PLWHA). Few studies have investigated social-psychological predictors of PTSD in China. This study aimed to examine relationships between social capital, stigma, resilience and PTSD among PLWHA in China, and to provide effective suggestions for PTSD intervention. A cross-sectional study of 520 PLWHA was conducted from November 2015 to January 2016. Survey data were collected using anonymous self-reported questionnaire. Multivariable analyses were used to examine related factors of PTSD, and causal mediation analyses were conducted to assess whether stigma and resilience were mediators. Results indicated that higher risk of PTSD was independent associated with stronger stigma, decreasing social capital and lower resilience. There was an indirect relationship of social capital on PTSD mediated through resilience and HIV-related stigma. Therefore, PTSD intervention programs should not only pay attention to the role of social capital on PTSD, but also attach importance to stigma and resilience on PTSD symptoms.

Visual working memory contaminates perception

Indirect evidence suggests that the contents of visual working memory may be maintained within sensory areas early in the visual hierarchy. We tested this possibility using a well-studied motion repulsion phenomenon in which perception of one direction of motion is distorted when another direction of motion is viewed simultaneously. We found that observers misperceived the actual direction of motion of a single motion stimulus if, while viewing that stimulus, they were holding a different motion direction in visual working memory. Control experiments showed that none of a variety of alternative explanations could account for this repulsion effect induced by working memory. Our findings provide compelling evidence that visual working memory representations directly interact with the same neural mechanisms as those involved in processing basic sensory events.     

New perspective on job burnout: exploring the root cause beyond general antecedents analysis

Previous studies of job burnout are discussed and three types of job burnout are presented and compared. Various studies of job burnout were reviewed in terms of participants, burnout situation, and root cause. Next, the framework of job burnout antecedents was reformulated, including characteristics of organizations, work, and individuals. Three types of job burnout-organizational weakness-caused burnout, work weakness-caused burnout, and individual characteristic-caused burnout-were posited based on the root causes contributing to job burnout. Finally, the three subcomponents of job burnout were compared on availability, concealment, universality, severity, duration, diffusibility, and changeability. Root causes of job burnout should be attended to in job burnout research and intervention programs.     

Naïve definitions of action and inaction: The continuum,spread, and valence of behaviors

The cohesiveness of a society depends, in part, on how its individual members manage their daily activities with respect to the goals of that society. Hence, there should be a degree of social agreement on what constitutes action and what constitutes inaction. The present research investigated the structure of action and inaction definitions, the evaluation of action versus inaction, and individual differences in these evaluations. Action–inaction ratings of behaviors and states showed more social agreement at the ends of the inaction–action continuum than at the middle, suggesting a socially shared construal of this definition. Action–inaction ratings were also shown to correlate with the valence of the rated behaviors, such that the more active the behavior, the more positive its valence. Lastly, individual differences in locomotion, need for closure, and Christian religious beliefs correlated positively with a preference for action. Copyright © 2011 John Wiley & Sons, Ltd.     

Gender and Age Group Differences in Mass Media and Interpersonal Influences on Body Dissatisfaction Among Chinese Adolescents

Despite evidence that middle adolescent girls (ages 14–17) experience more body dissatisfaction than early adolescent girls (ages 10–13) or boys at these ages, researchers have rarely considered whether such differences are observed regarding factors related to body dissatisfaction, particularly within non-Western samples. To address this issue, gender and age group differences in media and interpersonal influences on body dissatisfaction were assessed among early and middle adolescents living in Chongqing, China. In Study 1, 595 boys and 648 girls completed self report measures of demographics, public self-consciousness and appearance-based social pressure, comparisons, and conversations. Compared to boys, girls reported more appearance pressure from mass media and close interpersonal networks (friends, family), appearance comparisons with peers, and appearance conversations with friends; these effects were qualified by interactions with age group, indicating media and interpersonal factors were more prominent in the lives of middle adolescent girls than other groups. Effects were observed independent of body mass index (BMI) and public self-consciousness. In Study 2, 738 girls and 661 boys completed the same measures and a body dissatisfaction scale. By and large, gender and age differences were replicated. Middle adolescent girls also reported more body dissatisfaction than peers did. Perceived appearance pressure from mass media and interpersonal ties were both implicated in mediation analyses to explain this gender × age group effect.
