认知事件相关电位P_(300)与儿童的智力水平和年龄特征

诱发电位 (EP) ,亦称事件相关电位 (ERP) ,是神经系统活动功能的电生理指标。认知事件相关电位 P3 0 0 作为反映个体大脑认知功能的神经电生理的重要指标已经被许多有关研究所采纳。本研究从神经电生理的角度 ,一方面对认知事件相关电位 P3 0 0 与儿童的智力水平的关系进行测查 ,一方面对认知事件相关电位 P3 0 0 的年龄特点进行研究 ,以期了解和说明儿童认知发展的神经电生理基础及其年龄特征。实验表明 :儿童智力水平与 P3 0 0 各成分潜伏期呈负相关 ,与反映认知功能的主要指标 P3 的负相关达到非常显著水平 (P <0 .0 0 1 ) ,与 P3 0 0 各成分的振幅基本呈正相关 ,儿童不同智力水平之间 ,其反应认知功能的主要指标 P3 的潜伏期差异非常显著。儿童青少年 P3 0 0 的各潜伏期的发展总趋势随年龄增长而下降。其中 ,P3 的潜伏期随年龄增长而下降的趋势更为明显。P3 的振幅则随年龄增长而增大。六个年龄组间 P3 0 0 各成分差异均达到非常显著水平 (P <0 .0 0 1 )。     

认知事件相关电位P300与儿童青少年工作记忆的发展

研究采用ERP技术对59名儿童工作记忆水平与事件相关电位进行比较分析,以说明工作记忆发展的神经电生理基础及年龄特征。实验仪器为美国NICOLET公司生产的COMPACT FOUR脑诱发电位仪。结果发现:(1)儿童工作记忆水平与P300各成分潜伏期呈负相关,与P300各成分的振幅呈正相关。(2)儿童P300的各潜伏期随年龄增长而下降,振幅随年龄增长而增大。(3)不同性别儿童P300各成分均无显著性差异。     

3~8岁儿童自尊发展特点的研究

采用自编的《3~8岁儿童自尊教师评定量表》,探讨了3~8岁儿童自尊发展的年龄和性别差异。结果表明：(1)3~8岁儿童的自尊存在显著的年龄差异,4岁和7岁可能是儿童自尊发展的转折年龄;(2)3~8岁儿童自尊发展存在非常明显的性别差异,女生自尊发展水平显著高于男生。

The Effects of Personal Need for Structure and Occupational Identity in the Role Stress Process

Abstract

The authors formed and tested a model of the antecedents, consequences, and possible moderators or mediators of the role ambiguity construct in a new occupational group of nurses (N = 1,240) in Finland. They hypothesized that (a) job characteristics (control and feedback) would be associated with role ambiguity and (b) this association, in turn, would be moderated by personal need for structure. The authors hypothesized that role ambiguity would affect occupational strain partially by the strength of occupational identity. They tested these models by using hierarchical regression analysis and structural equation modeling (LISREL 8; K. G. Jöreskog & D. Sörbom, 1993). Both hypotheses were supported.     

Traditional and Modern Characteristics Across the Generations: Similarities and Discrepancies

Abstract

The authors examined, through an analysis of self-construals and beliefs about social interaction, the traditional and modern orientations of younger and older generations of Taiwanese people. The authors surveyed 169 pairs of parent-child dyads with a battery of structured questionnaires. Within-subjects analyses revealed high generational correlations as well as discrepancies in both traditional and modern characteristics. Between-subjects analyses further indicated that individual traditional and modern characteristics were affected by age and gender and by their interactions. The authors discuss (a) the pattern of generational similarities and discrepancies in the framework of culture stability and change and (b) the coexistence of traditional and modern characteristics in a rapidly changing society.     

Why borderline personality features adversely affect job performance: The role of task strategies

This study examined how Borderline Personality Disorder (BPD) and its components influence job performance. BPD is theorized to adversely affect the generation of task strategies in the workplace which results in poor job performance. In this study, 180 college students completed the Borderline Scale from the Personality Assessment Inventory (PAI-BOR; Morey, 1991) followed by a work-related simulation. While none of the facets of BPD related to task strategy, the composite of borderline negatively related to task strategy, which was positively related to task performance. Thus, borderline appears to have an indirect effect on task performance through task strategy.     

The role of emotion reactivity and gender in the relationship between psychopathology and self-injurious behavior

The goal of the present study was to examine emotion reactivity, a broad construct that consists of an individual’s sensitivity, intensity, and persistence of emotional reactions, as a mediator of the relationship between two types of psychopathology (depression symptoms and borderline personality disorder (BPD) symptoms) and history of self-injurious behavior (non-suicidal self-injury (NSSI) and suicide attempts (SA)). We also examined gender as a potential moderator of this relationship. Participants (N = 1914) completed measures of emotion reactivity, psychopathology, and self-injurious behavior. Results using a series of mediated path analyses indicated that emotion reactivity mediated the relationship between (1) depressive symptoms and NSSI in females only, (2) depressive symptoms and SA in females only, and (3) probable BPD diagnosis and NSSI in both genders. Emotion reactivity did not mediate the relationship between probable BPD diagnosis and SA in either gender. Our findings suggest that emotion reactivity is a possible pathway through which depression and self-injurious behavior relate, especially in women. We temper these findings, however, within the context of relatively modest observed effects.     

To switch or not to switch: Inviting bilingual clients to switch languages in psychotherapy

In the present study, we used an audio-analog design to test whether exposing bilingual participants to a therapist who invited a bilingual client to switch languages in a psychotherapy session would have a positive effect on participants’ perceptions of the therapist. We also explored whether participants’ sense of belonging to their ethnic group and to the larger US culture would enhance or attenuate this effect. Sixty-three bilingual Latino/a university students listened to one of two recordings of a simulated psychotherapy session with a bilingual Latina therapist and client. In one recording, the therapist invited the client to switch from English to Spanish when the client had trouble expressing complicated feelings; in the other, the therapist did not invite the client to switch. When listening, participants were asked to imagine themselves in the role of client and to rate the credibility and multicultural competence of the therapist, and the emotional bond they would anticipate with her. Contrary to expectation, only participants who expressed a greater sense of belonging to US culture rated the therapist who invited the client to switch as being more multiculturally competent. We discuss how these findings contribute to the literature on language switching and bilingualism in psychotherapy.
