同伴排斥与青少年早期饮酒行为:同伴侵害和不良同伴的中介效应

采用同伴提名、同伴侵害问卷、不良同伴问卷和饮酒行为问卷调查广东地区4所普通初级中学1386名7年级学生,考察了同伴排斥与青少年早期饮酒行为的关系,以及同伴侵害和结交不良同伴在其中的链式中介效应。结果发现:(1)同伴排斥、同伴侵害和结交不良同伴均与青少年早期的饮酒行为呈显著正相关;(2)同伴侵害和结交不良同伴在同伴排斥影响青少年早期饮酒行为过程中的链式中介效应显著,即同伴排斥通过增加同伴侵害,从而提高结交不良同伴的风险,进而增加青少年早期的饮酒行为;(3)在控制同伴侵害和结交不良同伴后,同伴排斥对青少年早期的饮酒行为仍存在显著预测作用。     

面孔审美加工的神经机制及个体差异

外显和内隐的面孔审美加工的脑成像研究表明,美的面孔比不美的面孔导致眶额皮层、伏隔核、杏仁核等奖赏脑区更大的激活。脑电研究则发现了与面孔审美加工有关的早期负波和晚期正成分。面孔审美加工有关的脑区活动也受到性别、生理周期等个体因素的调节。未来的研究需要比较美的面孔与其它奖赏刺激加工的神经机制,探讨面孔审美加工的不同阶段及时间进程,在面孔知觉的框架下形成合理的面孔审美加工的神经模型。     

有性Penna模型:进化心理学的新工具

进化心理学家以进化论为基础,使用了许多不同的方法来研究人类的心灵。这些方法都有共同的缺陷,即无法直接对提出的假设进行验证,对复杂的系统进行研究难度很大,计算机模拟的方法可在一定程度上修补该问题。有性Penna模型能反映有性生殖种群的进化特点,能反映环境对生物进化的影响,通过该模型来模拟人类进化历程,则可以检验某一心理机制是否是适应的,它是研究生物进化的有力工具。本文在综述已有研究成果的基础上提出用有性Penna模型对进化心理学关于进化轨迹的假设进行验证的构想,并在此基础之上提出了用该模型进行研究的基本框架。     

Perceived interpersonal sources of life satisfaction in Chinese and American students: Cultural or gender differences?

This study evaluated cultural and gender differences in perceived interpersonal sources of life satisfaction between 341 Chinese and 222 American college students. Comparative analyses indicated overall lower life satisfaction in Chinese, than in Americans. However, Chinese, compared to Americans, reported greater life satisfaction derived from perceived sources involving the self, parents, teachers and peers. Results of regression analyses indicated that, for both Chinese and Americans, the self and parents were unique sources associated with life satisfaction. However, for Americans, close friends also emerged as an additional unique source. When gender differences were examined, additional nuances were found within each cultural group. Thus, some evidence for both cultural and gender differences in perceived interpersonal sources of life satisfaction across Chinese and Americans was found. Some implications of the present findings are discussed.     

Short-term and long-term attentional biases to frequently encountered target features

It has long been known that frequently occurring targets are attended better than infrequent ones in visual search. But does this frequency-based attentional prioritization reflect momentary or durable changes in attention? Here we observed both short-term and long-term attentional biases for visual features as a function of different types of statistical associations between the targets, distractors, and features. Participants searched for a target, a line oriented horizontally or vertically among diagonal distractors, and reported its length. In one set of experiments we manipulated the target’s color probability: Targets were more often in Color 1 than in Color 2. The distractors were in other colors. Participants found Color 1 targets more quickly than Color 2 targets, but this preference disappeared immediately when the target’s color became random in the subsequent testing phase. In the other set of experiments, we manipulated the diagnostic values of the two colors: Color 1 was more often a target than a distractor; Color 2 was more often a distractor than a target. Participants found Color 1 targets more quickly than Color 2 targets. Importantly, and in contrast to the first set of experiments, the featural preference was sustained in the testing phase. These results suggest that short-term and long-term attentional biases are products of different statistical information. Finding a target momentarily activates its features, inducing short-term repetition priming. Long-term changes in attention, on the other hand, may rely on learning diagnostic features of the targets.     

Cultural Identity and the Expression of Depression: A Social Identity Perspective

The present research interrogates the greater tendency for Chinese people to somaticize depression relative to Westerners. Drawing from a social identity perspective, three studies were conducted examining the role that cultural norms play in symptom expression. In an initial study, we confirmed greater somatization, minimization of distress and suppression of emotional expression among Chinese participants compared with Australians (Study 1). Asian normative expectations of collectivism moderated these effects such that somatization was higher among those who endorsed collectivism norms, but only among Chinese participants. Studies 2a and 2b found that only when Asian participants identified strongly with Asian culture did collectivism norms predict somatic symptoms. These findings have implications for practitioners working with people from Asian cultures, highlighting that it is not culture per se, but the endorsement of normative expectations in the context of strong identification with cultural groups that predicts which symptoms of depression are emphasized.

Gratitude and Athletes’ Life Satisfaction: The Moderating Role of Mindfulness

Life satisfaction is a critical index of well-being and is well documented in the literature as a means of protecting athletes from stress. However, minimal research has focused on the factors that contribute to life satisfaction in sports. Accordingly, we adopted the positive psychology perspective and proposed that gratitude would relate to athletes’ life satisfaction. Additionally, we further suggested that mindfulness would strengthen the relationship between gratitude and athletes’ life satisfaction. Athletes completed measurements, and the results, which indicated that athletes with higher levels of gratitude exhibited increased life satisfaction when they had higher levels of mindfulness, supported our expectations. The implications and applications are discussed in terms of mindfulness.     

Electrophysiological and behavioral evidence reveals the effects of trait anxiety on contingent attentional capture

Few studies have investigated the effects of anxiety on contingent attentional capture. The present study examined contingent attentional capture in trait anxiety by applying a rapid serial visual presentation (RSVP) paradigm during electroencephalographic recording. Overall, the behavioral and electrophysiological results showed a larger capture effect when a distractor was the same color as the target compared to when the distractor was not of the target color. Moreover, high-anxiety individuals showed a larger N2pc in the target colored distractor condition and nontarget colored distractor condition compared to the distractor-absent condition. In addition, the reaction time was slower when distractors were presented in the left visual field compared to when they were in the right visual field. This pattern was not seen in low-anxiety individuals. The findings may indicate that high-anxiety individuals allocate attention to the target less efficiently and have reduced suppression of distractors compared to low-anxiety individuals who could suppress attention to the distractors more efficiently. Future work could valuably investigate the consequences of such differences in terms of benefits and disruption associated with attentional capture differences in a range of anxious populations in different risk monitoring situations.     

Self-concept integration and differentiation in subclinical individuals with dissociation proneness

Dissociative pathology is characterized by an altered sense of self. Still, it remains unclear (a) whether the altered sense of self is also associated with non-pathological dissociation as well and (b) whether this potential association is an intrinsic connection or a consequence of other related constructs, including childhood trauma. This study addresses this question by examining how self-concept organization may differ among individuals with different levels of dissociation proneness. The structure of self-concept was operationalized by various indexes of self-concept integration and differentiation. Results showed that individuals high in dissociation proneness have lower self-concept clarity and compartmentalize self-aspects with more polarized evaluations. Notably, the association between dissociation proneness and evaluative self-compartmentalization held after controlling for childhood trauma, anxiety, and depression. This characteristic self-concept organization can be an attribute of non-pathological dissociation.
