School Context Protective Factors Against Peer Ethnic Discrimination Across the High School Years

Ethnically diverse high school contexts present unique social opportunities for youth to form interethnic relationships, but they may also subject students to certain social challenges such as peer ethnic discrimination. With a sample of 1,072 high school students (55% girls; 54% Latino, 20% African American, 14% Asian, 12% White) attending 84 high schools, school context factors that protect students’ exposure to peer ethnic discrimination across the high school years were investigated with a three-level hierarchical linear model. Each spring for four consecutive years (grades 9–12), self-reported peer ethnic discrimination, interracial climate at school, and perceived school ethnic composition were assessed. At the school level, objective high school ethnic composition data were collected. Peer ethnic discrimination was found to decline slightly across the high school years. Above and beyond this decline, more positive perceptions of the school interracial climate and both objective and perceived numerical ethnic majority status predicted lower levels of peer ethnic discrimination. Taken together, the results highlight the significance of both objective (e.g., ethnic composition) and subjective (e.g., interracial climate) aspects of the school ethnic context to students’ high school social experiences.     

蒙语词汇识别中语音自动激活的ERP研究

采用快速掩蔽启动范式、Go/No-go范式和事件相关电位（ERP）技术,探讨蒙语词汇识别过程中语音自动激活的时程及对语义通达的作用。实验中要求被试执行一个额外的语义分类任务,对关键刺激不做明显的行为反应。结果发现,SOA为67ms时,语音启动在头皮的额区诱发了明显的P150和N400成分;SOA为167ms时,语音启动在头皮的额区和中央区诱发了明显的P200成分,在整个大脑皮层诱发了明显的N400成分。结果表明,语音在蒙语词汇识别的早期自动激活并促进语义的通达。     

空间转换在记叙文阅读情境模型建构中的作用

采用探测词和事件分割范式探讨了空间转换与事件转换分离的情况下, 空间转换在记叙文情境模型建构中的作用。实验1a重复前人研究, 探讨空间转换对阅读时间和情境模型更新的影响, 并验证在空间转换对情境模型的影响的研究中, 采用多指标探测范式的合理性。实验1b探讨在空间转换与事件转换相分离的条件下, 空间转换对情境模型更新的影响; 实验2a探讨空间转换对事件分割的影响, 并验证在空间转换对情境模型的影响的研究中, 采用事件分割范式的合理性; 实验2b探讨空间转换与事件转换相分离的条件下, 空间转换对事件分割的影响, 从而验证空间转换对情境模型更新的影响。结果表明, 当空间转换与事件转换相分离时, 不引起情境模型的更新, 事件单元是建构记叙文心理表征的核心单元, 空间转换只有在标识事件转换的情况下, 才能引发读者更新情境模型。     

Differential Roles of Physical Attractiveness and Earning Capability in Explaining Sense of Power among Dating Individuals in China: A Gender Comparison

This cross-sectional study examined how self-assessed physical attractiveness and earning capability were associated with individuals’ sense of power through self-perceived mating success and investment size in romantic relationships among 196 young adults (88 men, 98 women) from Nanjing, China. Using path analysis, we tested the following hypotheses: self-assessed physical attractiveness would be more strongly associated with self-perceived mating success among women than men, whereas self-assessed earning capability would be more strongly linked to self-perceived mating success among men than women (H1); relative physical attractiveness, as compared to their partners’, would be more strongly associated with men’s rather than women’s self-perceived investment size, whereas relative earning capability would be more strongly related to women’s rather than men’s investment size (H2); for both men and women, self-perceived mating success would be positively associated with sense of power, whereas self-perceived investment size would be negatively associated with sense of power (H3). Results indicated that self-perceived physical attractiveness and earning capability were associated with self-perceived mating success similarly for both men and women, failing to support H1. Whereas relative physical attractiveness was negatively associated with investment in the relationship similarly for two genders, the negative association between relative earning capacity and investment size was only significant for women. H2 was partially supported. Finally, self-perceived mating success and investment size were significantly associated with sense of power in the expected directions for both genders, lending support to our H3. Results are discussed in light of gender differences in mate preferences and the investment theory.

父母教养投入对青少年亲社会行为的影响:亲子依恋的中介作用

在北京、广东、河南、辽宁等省市的20所中小学中选取小学五年级、初中二年级和高中二年级学生共2370名,采用父母教养投入问卷（青少年版）、亲子依恋问卷和亲社会行为问卷,通过结构方程模型探讨青少年感知的父母教养投入行为对其亲社会行为的影响及其作用机制。结果表明：（1）青少年感知的父母教养投入显著正向预测青少年的亲社会行为,母亲的影响显著大于父亲;（2）亲子依恋在父母教养投入对青少年亲社会行为的影响中具有中介作用;（3）父亲和母亲教养投入影响青少年亲社会行为的作用机制存在差异,其中父亲教养投入通过父子依恋的完全中介作用对亲社会行为产生正向影响;母亲教养投入对亲社会行为的影响既会通过母子依恋的部分中介作用发挥积极作用,也会通过父子依恋的遮掩效应产生负向削弱作用。     

自我效能感影响航线飞行安全绩效的多重中介模型

采用问卷法调查了138名民航飞行员,探讨了自我效能感对飞行安全绩效的影响,以及在这一影响过程中组织信任、组织承诺和工作投入的作用。结果显示,自我效能感对组织信任、组织承诺、工作投入和安全绩效有直接正向作用。组织信任在自我效能感对组织承诺、工作投入、安全绩效的影响中有部分中介作用。组织承诺与工作投入在自我效能感对安全绩效影响中发挥着部分中介作用。结论:自我效能感对安全绩效有直接效应,并可通过组织信任、组织承诺和工作投入对安全绩效产生间接影响。     

TISK 1.0: An easy-to-use Python implementation of the time-invariant string kernel model of spoken word recognition

This article describes a new Python distribution of TISK, the time-invariant string kernel model of spoken word recognition (Hannagan et al. in Frontiers in Psychology, 4, 563, 2013). TISK is an interactive-activation model similar to the TRACE model (McClelland & Elman in Cognitive Psychology, 18, 1–86, 1986), but TISK replaces most of TRACE’s reduplicated, time-specific nodes with theoretically motivated time-invariant, open-diphone nodes. We discuss the utility of computational models as theory development tools, the relative merits of TISK as compared to other models, and the ways in which researchers might use this implementation to guide their own research and theory development. We describe a TISK model that includes features that facilitate in-line graphing of simulation results, integration with standard Python data formats, and graph and data export. The distribution can be downloaded from https://github.com/maglab-uconn/TISK1.0.     

An item response theory analysis of the Impulsive Behaviors Checklist for Adolescents

This study used item response theory (IRT) to examine the Impulsive Behaviors Checklist for Adolescents (IBCL-A) among 6,276 (67.7% girls) Chinese secondary school students. The IBCL-A included 15 maladaptive impulsive behaviors adapted from the Revised Diagnostic Interview for Borderlines. The authors obtained the severity and discrimination parameters for each item in the IBCL-A, examined differential item functioning across gender and age groups, and tested reliability and concurrent validity of the IBCL-A IRT-scaled score. Most items in the IBCL-A were the most accurate in assessing moderate to high levels of impulsivity and discriminated well among adolescents with varied levels of impulsivity. Differential item functioning emerged in several items across gender. The IRT-scaled score showed good construct validity and incremental predictive validity. Findings demonstrate the sound psychometric properties of the IBCL-A and support the clinical utility of this scale.     

高二学生情绪调节方式与父母反应方式的关系

以自我决定理论为理论依据,对500名高二学生进行问卷调查,采用结构方程模型的统计方法分析了在悲伤、害怕、生气三种情绪条件下,父亲、母亲的反应方式与高二男生、女生情绪调节方式之间的两种关系模型。模型比较结果显示,父、母反应方式对高二年级青少年情绪调节方式的预测作用小于高二年级青少年情绪调节方式对其父、母反应方式的预测作用,这一点在女生身上更为突出;高二年级青少年的情绪调节方式与其父母反应方式之间的关系表现出了性别差异;在不同情绪条件下,高二年级青少年的情绪调节方式对父母反应方式的预测关系表现出了一致性;父亲、母亲对高二学生消极情绪调节方式的反应也表现出了一致性。
