家庭经济压力与青少年抑郁:歧视知觉和亲子依恋的作用

对703名初中生(平均年龄14.30岁)进行问卷调查, 探讨了青少年歧视知觉、亲子依恋在家庭经济压力与青少年抑郁关系中的中介和调节作用。结果表明:(1)在控制了性别、年级后, 家庭经济压力对青少年抑郁具有显著的正向预测作用;(2)在家庭经济压力对抑郁的正向预测关系中, 歧视知觉起中介作用;(3)家庭经济压力通过歧视知觉对抑郁的中介作用受到亲子依恋的调节, 相对于亲子依恋水平较高的青少年, 中介效应仅在亲子依恋水平较低的青少年中显著。     

蒙汉族大学生父母教养方式、成人依恋与心理困扰的关系研究

通过整群抽样方法抽取了576名大学生,对其施测父母养育方式量表、亲密关系体验量表和心理困扰量表,运用结构方程模型技术,分别考察了父母养育方式的蒙汉族差异以及成人依恋模式在父母养育方式和心理困扰间的中介作用。结果表明:(1) 蒙古族父母对孩子的关爱程度和给孩子的自主性要显著高于汉族;(2) 汉族的成人依恋模式在父母过度保护与抑郁-焦虑-压力之间起着部分中介作用,而蒙古族成人依恋的中介作用不明显,但母亲的冷漠拒绝和过度保护会导致个体依恋回避和依恋焦虑,父亲的冷漠拒绝和过度保护会影响个体的抑郁和焦虑,母亲的过度保护和父亲的冷漠拒绝会影响个体的压力。     

注意力资源限制与双任务的相互干扰机制

采用心理不应期研究范式, 两个反应时实验检测了注意力资源分配的特征以及双任务的相互干扰机制。每次实验中, 要求被试快速、相继对高低音辨别任务(T1)和Stroop任务(T2)作出选择性反应, T1和T2间采用6种不同的时间间隔(SOA), 以系统考察不同SOA条件下两个任务的反应时走势。结果发现：(1) 在重叠的双任务情境中, T1的中枢加工导致在T2上出现显著的PRP效应, T2的中枢反应选择对T1的反应选择和反应执行加工同样产生显著的影响。SOA以及T2的难度与复杂度实质性地影响了T1的反应选择和反应执行加工。(2) 当两个任务同时需要进行中枢反应选择加工时, 一个任务占用更多的注意资源将导致另一任务获得较少的注意资源, 注意资源量的多寡直接决定了该任务的加工效率。(3) 两个任务的加工相互影响、相互制约, 这种制约机制不仅仅存在于中枢反应选择阶段, 在反应执行阶段仍然存在。     

高焦虑个体对威胁性刺激的注意偏向特点*

采用点探测实验范式,将图片按照威胁性分为高威胁性和一般威胁性,探讨焦虑程度不同的个体对不同威胁性刺激的注意特点。采用状态-特质焦虑问卷从265个大学生中选取了33名高焦虑被试和31名对照组被试。结果发现：（1）高焦虑组个体对一般威胁性刺激有显著注意偏向,对高威胁性刺激有注意回避趋势;（2）对照组个体对一般威胁性刺激没有表现出注意偏向,对高威胁刺激有注意偏向趋势。结论：（1）即使是一般威胁性图片也能引起高焦虑被试的注意偏向 （2）高威胁性图片才能引起对照组个体产生注意偏向的趋势。     

Rosenberg Self-Esteem Scale: Method Effects,Factorial Structure and Scale Invariance Across Migrant Child and Urban Child Populations in China

Using confirmatory factor analyses, this study examined the method effects on a Chinese version of the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965 Rosenberg, M. (1965). Society and the adolescent self-image. Princeton, NJ: Princeton University Press.[Crossref] , [Google Scholar]) in a sample of migrant and urban children in China. In all, 982 children completed the RSES, and 9 models and 9 corresponding variants were specified and tested. The results indicated that the method effects are associated with both positively and negatively worded items and that Item 8 should be treated as a positively worded item. Additionally, the method effects models were invariant across migrant and urban children in China.     

Repetition Priming Effects in Proficient Mandarin–Cantonese and Cantonese–Mandarin Bidialectals: An Event-Related Potential Study

The present study adopted a repetition priming paradigm to investigate the bidialectal (bilingual) representation of speakers with different native dialects by event-related potential (ERP) technique. Proficient Mandarin–Cantonese and Cantonese–Mandarin bidialectals participated in the study. They were required to judge whether a word was a biological word or not, when the words (target word) were represented under four types of repetition priming conditions: Mandarin (prime)–Mandarin (target), Mandarin (prime)–Cantonese (target), Cantonese (prime)–Cantonese (target) and Cantonese (prime)–Mandarin (target). Results of reaction time and accuracy primarily indicated larger repetition priming effects in Mandarin–Mandarin and Cantonese–Cantonese (within-language) conditions than that in Mandarin–Cantonese and Cantonese–Mandarin (between-language) conditions. But more importantly, P200 and N400 mean amplitudes revealed distinct repetition priming effects between two types of participants. Specifically, both P200 and N400 indicated that the repetition priming effect in Mandarin–Mandarin condition was larger than that in Cantonese–Cantonese condition for Mandarin–Cantonese participants, whereas it was opposite for Cantonese–Mandarin participants. In addition, P200 also suggested opposite patterns of repetition priming effects in between-language priming conditions for two groups of participants. The repetition priming effect in Mandarin–Cantonese condition was larger than that in Cantonese–Mandarin condition for Mandarin–Cantonese participants, while for Cantonese–Mandarin participants, it was opposite (Mandarin–Cantonese < Cantonese–Mandarin). The results implied a clear asymmetric representation of two dialects for proficient bidialectals. They were further discussed in light of native dialect and language use frequency.     

Be loyal but not addicted: Effect of online game social migration on game loyalty and addiction

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

Do ad metaphors enhance or dilute the consumers' brand preferences? Exploring the moderating role of goal orientation

This research aims to explore the impacts of ad metaphors and goal orientation on the relationship between brand commitment and attitudes toward the competitor brands. Results show that prevention‐focused consumers with high brand commitment do not exhibit differentially favorable attitudes toward the competitor brands, regardless of ad metaphors. In contrast, prevention‐focused consumers with low brand commitment exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads. Moreover, promotion‐focused consumers exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads, regardless of brand commitment.     

Scanpath estimation based on foveated image saliency

The estimation of gaze shift has been an important research area in saliency modeling. Gaze movement is a dynamic progress, yet existing estimation methods are limited to estimating scanpaths within only one saliency map, providing results with unsatisfactory accuracy. A bio-inspired method for gaze shift prediction is thus proposed. We take the effect of foveation into account in the proposed model, which plays an important role in the search for dynamic salient regions. The saccadic bias of gaze shifts and the mechanism of inhibition of return in short-term memory are also considered. Based on the probability map derived from these factors, candidates for the next fixation can be randomly generated, and the final scanpath can be acquired point by point. By the evaluation of objective measures, experimental results show that this method possesses better performance in several datasets than many existing models do.
