We study computably enumerable equivalence relations (ceers) on N and unravel a rich structural theory for a strong notion of reducibility among ceers.     

地震对灾民创伤后应激障碍的长期影响

创伤后应激障碍是震后最常见的心理创伤。以往研究多关注灾民在震后短时间内的应激反应, 地震两年后创伤心理研究非常缺乏。本研究拟结合汶川地震后进行的6次重复测量数据(2008~2016)重点探讨：创伤后应激障碍在震后不同时点的变化轨迹及影响因素; 震后针对创伤后应激障碍在不同时点的干预内容。预期研究成果不仅是对灾后心理创伤长期影响研究的补充, 也将为灾后救助政策以及心理干预提供依据。

Conflict Resolution in Chinese Adolescents' Friendship: Links with Regulatory Focus and Friendship Satisfaction

It is generally acknowledged that people adopt different resolution strategies when facing conflicts with others. However, the mechanisms of conflict resolution are still unclear and under researched, in particular within the context of Chinese adolescents' same-sex friendship relations. Thus, the present study investigated the mediator role of conflict resolution strategies in the relationship between regulatory foci and friendship satisfaction for the first time. 653 Chinese adolescents completed the regulatory foci, conflict resolution style, and friendship satisfaction measures. The results of the structure equation modeling showed that while promotion focus was positively associated with problem-solving and compliance, prevention focus was positively associated with withdrawal and conflict engagement. In addition, problem-solving mediated the relationship between promotion focus and friendship satisfaction, and conflict engagement mediated the relationship between prevention focus and friendship satisfaction. These findings contribute to understanding Chinese adolescents' use of conflict resolution strategies as well as the relationship between regulatory foci and behavioral strategies in negative situations.     

心理韧性、孤独感、自我效能感预测老年人主观幸福感的优势分析

心理韧性、孤独感、自我效能感都会影响老年人的主观幸福感,但三者影响程度的相对大小尚不清楚。为考察其影响力的大小,本研究采用了优势分析的方法。选取心理韧性量表、UCLA孤独量表、一般自我效能感量表分别测量老年人的心理韧性、孤独感、自我效能感,主观幸福感量表、费城老年中心信心量表测量老年人主观幸福感。优势分析结果表明,孤独感对老年人主观幸福感的预测力大于心理韧性与自我效能感;心理韧性的预测力大于自我效能感。本研究提示减少孤独感是提升老年人主观幸福感的重要途径,而老年人的心理韧性和自我效能感对提升老年人主观幸福感有一定的作用。     

Bindings in working memory: The role of object-based attention

Over the past decade, it has been debated whether retaining bindings in working memory (WM) requires more attention than retaining constituent features, focusing on domain-general attention and space-based attention. Recently, we proposed that retaining bindings in WM needs more object-based attention than retaining constituent features (Shen, Huang, & Gao, 2015, Journal of Experimental Psychology: Human Perception and Performance, doi: 10.1037/xhp0000018). However, only unitized visual bindings were examined; to establish the role of object-based attention in retaining bindings in WM, more emperical evidence is required. We tested 4 new bindings that had been suggested requiring no more attention than the constituent features in the WM maintenance phase: The two constituent features of binding were stored in different WM modules (cross-module binding, Experiment 1), from auditory and visual modalities (cross-modal binding, Experiment 2), or temporally (cross-time binding, Experiments 3) or spatially (cross-space binding, Experiments 4–6) separated. In the critical condition, we added a secondary object feature-report task during the delay interval of the change-detection task, such that the secondary task competed for object-based attention with the to-be-memorized stimuli. If more object-based attention is required for retaining bindings than for retaining constituent features, the secondary task should impair the binding performance to a larger degree relative to the performance of constituent features. Indeed, Experiments 1–6 consistently revealed a significantly larger impairment for bindings than for the constituent features, suggesting that object-based attention plays a pivotal role in retaining bindings in WM.     

The effects of the binocular disparity differences between targets and maskers on visual search

A visual search for targets is facilitated when the target objects are on a different depth plane than other masking objects cluttering the scene. The ability of observers to determine whether one of four letters presented stereoscopically at four symmetrically located positions on the fixation plane differed from the other three was assessed when the target letters were masked by other randomly positioned and oriented letters appearing on the same depth plane as the target letters, or in front, or behind it. Three additional control maskers, derived from the letter maskers, were also presented on the same three depth planes: (1) random-phase maskers (same spectral amplitude composition as the letter masker but with the phase spectrum randomized); (2) random-pixel maskers (the locations of the letter maskers’ pixel amplitudes were randomized); (3) letter-fragment maskers (the same letters as in the letter masker but broken up into fragments). Performance improved with target duration when the target-letter plane was in front of the letter-masker plane, but not when the target letters were on the same plane as the masker, or behind it. A comparison of the results for the four different kinds of maskers indicated that maskers consisting of recognizable objects (letters or letter fragments) interfere more with search and comparison judgments than do visual noise maskers having the same spatial frequency profile and contrast. In addition, performance was poorer for letter maskers than for letter-masker fragments, suggesting that the letter maskers interfered more with performance than the letter-fragment maskers because of the lexical activity they elicit.     

Interaction between Prenatal Maternal Stress and Autonomic Arousal in Predicting Conduct Problems and Psychopathic Traits in Children

Evidence has suggested that neurobiological deficits combine with psychosocial risk factors to impact on the development of antisocial behavior. The current study concentrated on the interplay of prenatal maternal stress and autonomic arousal in predicting antisocial behavior and psychopathic traits. Prenatal maternal stress was assessed by caregiver’s retrospective report, and resting heart rate and respiratory sinus arrhythmia (RSA) were measured in 295 8- to 10-year-old children. Child and caregiver also reported on child’s antisocial behavior and psychopathic traits. Higher prenatal maternal stress was associated with higher caregiver-reported antisocial and psychopathy scores, even after the concurrent measure of social adversity was controlled for. As expected, low heart rate and high RSA were associated with high antisocial and psychopathic traits. More importantly, significant interaction effects were found; prenatal stress was positively associated with multiple dimensions of psychopathic traits only on the conditions of low arousal (e.g., low heart rate or high RSA). Findings provide further support for a biosocial perspective of antisocial and psychopathic traits, and illustrate the importance of integrating biological with psychosocial measures to fully understand the etiology of behavioral problems.     

Proactive Personality and Job Satisfaction: the Mediating Effects of Self-Efficacy and Work Engagement in Teachers

Proactive personality has been demonstrated to be positively correlated with individual’s job satisfaction in addition to big five traits. However, what is less clear are the intervening mechanisms underlying this relationship, the present study examined the mediating effects of self-efficacy and work engagement on the association between proactive personality and job satisfaction. Three hundred and fifty-two (194 females and 158 males) primary and middle school teachers completed the proactive personality scale, the teachers’ self-efficacy scale, the work engagement scale and the short-form Minnesota job satisfaction questionnaire. Results revealed that proactive personality was positively related to teachers’ job satisfaction. In addition, mediation analyses showed that the relation between proactive personality and teachers’ job satisfaction was simple mediated by self-efficacy and work engagement and sequentially mediated by self-efficacy–work engagement. These findings contribute to the complex nature of the relationship between proactive personality and job satisfaction. The possible explanations and limitations are briefly discussed.
