工作记忆、加工速度与流体智力的发展

近几年有关认知发展心理机制的研究成为一个认知发展领域一个颇引人注目的内容．这些研究探讨了年龄、工作记忆、加工速度与流体智力之间的关系。研究发现．在流体智力的发展过程中,工作记忆可能比加工速度发挥着更直接、更一般的作用,而加工速度则对工作记忆的发展起直接调节作用。     

班级环境变量对儿童社会行为与学校适应间关系的影响

运用同伴提名和问卷法,对82个城市初中班级的4650名学生进行了测试,并使用多水平分析技术探讨了班级环境变量对儿童社会行为和学校适应间关系的影响。结果显示：儿童的亲社会行为可以显著地正向预测其同伴接受和学业成就,儿童的攻击、退缩行为对学业成就和同伴接受有明显的负向预测效果;在班级环境变量方面,老师支持可以减弱退缩行为和学校适应间的负向联系;老师训诫不仅可以减弱攻击行为与同伴接受间的负向关联,并且对退缩行为与学业成就之间的负向联系也具有削弱效果;同学关系这一变量的班级效果最为明显,可以明显地增强儿童问题行为与学校适应间的负向联系;而班级秩序纪律对攻击行为和学校适应间的负向关联有明显的强化效果。     

White Racial Identity and Attitudes Toward People With Disabilities

This empirical study investigated the relationship between racial identity and attitudes toward people with disabilities. Results indicate that higher statuses of racial identity correlate positively while lower and more racist‐oriented statuses correlate negatively with attitudes toward people with disabilities. The study supports the notion that attitudes from cultural memberships associated with power can transfer from one domain (i.e., White/People of Color) to another domain (i.e., Abled/Disabled). Este estudio empírico investigó la relación entre la identidad y actitudes raciales hacia personas con incapacidades. Los resultados indican que las posiciones más altas de la identidad racial se pone en correlación positivamente mientras bajan y más posiciones racista‐orientados se pone en correlación negativamente con actitudes hacia personas con incapacidades. El estudio sostiene la noción que actitudes de asociaciones culturales asociadas con el poder pueden transferir de un dominio (es decir, los Blancos/Personas del Color) a otro dominio (es decir, Capacitados/Incapacitados).     

不同年龄阶段Stroop效应及反转Stroop效应的特点

本实验以中学生和大学生为被试对Stroop效应及反转Stroop效应的年龄特征进行了研究,结果发现:在错误率指标上存在显著的年龄主效应,初中生的错误率显著高于大学生和高中生,高中生和大学生的差异不显著;颜色判断和单字判断任务中,不一致条件的反应时和错误率都显著高于一致条件的反应时和错误率,即两种任务分别产生了Stroop效应和反转的Stroop效应.     

青老年组不同难度下心算活动的脑功能磁共振成像研究

应用功能磁共振成像技术研究不同心算难度下脑区的活动以及年龄的影响。14名志愿者（20～29岁青年和60～69岁老年被试各7名）参加了该实验。实验任务为2个难度水平的连续减法心算,分别为1000—3和1000—17。结果表明：（1）心算加工激活了额叶和顶叶的许多脑区;（2）大脑左半球是心算加工的优势半球,但随着心算难度加大,大脑一侧化程度下降,而年老加剧了这一趋势;（3）青年组进行简单心算（1000—3）时,额中回未见明显激活,而老年组进行简单心算时,该脑区被明显激活。总体上,额叶和顶叶在心算活动中起着重要作用,而任务难度和年龄对心算加工时脑活动的影响以额中回区最为明显。     

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.
