工作记忆容量对创造性思维的预测

创造性思维(CT)是人类高级认知的重要组成部分,而工作记忆容量(WMC)是个体认知功能的重要指标,对于WMC能否预测CT存在不同的观点。本文先从正向预测、负向预测和不能预测的角度分类总结了相关研究证据,然后用游乐园模型(APT)、双通道模型(DPCM)和注意控制理论(CAT)对不同结果进行解释,分析了以往研究可能存在的问题,包括测量WMC和测量CT的任务类型不匹配、测量CT的领域特殊性问题、忽略其他认知能力差异以及未考虑智力、人格等因素对二者关系的影响等。最后,结合已有问题与当前的研究重点对未来研究进行了相应的展望。     

三重自我建构的神经机制

三重自我建构理论（the tripartite model of self-construal）认为,自我包含三个方面：个体自我,关系自我和集体自我;三种自我同时存在。研究发现：相比其他信息,三种自我均诱发了更强的N2（熟悉度指标）、P300（高级认知加工指标）成分以及与自我加工有关的MPFC脑区;个体自我存在右脑优势,而集体自我则存在左脑优势。但其具体表征脑区,其在中国文化背景下的文化特异性,以及不同关系类型、群体范畴是否能进一步划分关系和集体自我等问题均有待探讨。     

Evidence for an emotion-cognition interaction in the statistical prediction of suicide attempts

Suicidal behavior is a prevalent problem among adolescents and young adults. Although most theoretical models of suicide suggest that this behavior results from the interaction of different risk factors, most prior studies have tested only bivariate associations between individual risk factors and suicidal behaviors. The current study was designed to address this limitation by testing the effect of an emotion–cognition interaction on suicide attempts among youth. Specifically, we hypothesized that the interaction of emotion reactivity and problem-solving skills would statistically predict the probability of a recent suicide attempt among 87 adolescents and young adults. Results revealed a significant interaction, such that emotion reactivity was strongly associated with the probability of a suicide attempt among those with poor problem-solving skills, moderately associated among those with average problem-solving skills, and not significantly associated among those with good problem-solving skills. The next generation of studies on suicidal behavior should continue to examine how risk factors interact to predict this dangerous outcome.     

Optimism and the Big Five factors of personality: Beyond Neuroticism and Extraversion

The purpose of the present study was to investigate the relationship between the Big Five factors of personality and dispositional optimism. Data from five samples were collected (Total N = 4332) using three different measures of optimism and five different measures of the Big Five. Results indicated strong positive relationships between optimism and four of the Big Five factors: Emotional Stability, Extraversion, Agreeableness, and Conscientiousness. Agreeableness and Conscientiousness explained additional variance in dispositional optimism over and above Neuroticism and Extraversion, providing evidence for the complexity of optimism. The position of optimism in the larger web of human personality constructs is discussed.     

A latent profile analysis of the Five Factor Model of personality: Modeling trait interactions

Interactions among the dimensions of the Five Factor Model (FFM) have not typically been evaluated in mental health research, with the extant literature focusing on bivariate relationships with psychological constructs of interest. This study used latent profile analysis to mimic higher-order interactions to identify homogenous personality profiles using the FFM, and also examined relationships between resultant profiles and affect, self-esteem, depression, anxiety, and coping efficacy. Participants (N = 371) completed self-report and daily diary questionnaires. A 3-profile solution provided the best fit to the data; the profiles were characterized as well-adjusted, reserved, and excitable. The well-adjusted group reported better psychological functioning in validation analyses. The reserved and excitable groups differed on anxiety, with the excitable group reporting generally higher anxiety than the reserved group. Latent profile analysis may be a parsimonious way to model personality heterogeneity.     

基于技术接受模型的青少年网络游戏成瘾机制研究

本研究以技术接受模型(TAM)为理论框架, 通过对380名中学生的问卷调查考察了青少年网络游戏成瘾的影响因素及其机制。结果发现:(1)有用感、易用感、品质感知、游戏体验和态度与网络游戏成瘾显著正相关;(2)品质感知和游戏体验通过态度的部分中介作用对网络游戏成瘾产生间接影响, 同时对网络游戏成瘾有直接效应;有用感和易用感通过态度的完全中介作用对网络游戏成瘾产生间接影响, 对网络游戏成瘾没有直接效应。本研究结果表明, 品质感知、有用感、易用感和游戏体验对青少年网络游戏成瘾具有重要影响, 态度是其中的重要中介变量。     

Right‐wing authoritarianism and social dominance orientation and the dimensions of generalized prejudice: A longitudinal test

A Dual Process Model (DPM) approach to prejudice proposes that there should be at least two dimensions of generalized prejudice relating to outgroup stratification and social perception, which should be differentially predicted by Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). The current study assessed the causal effects of SDO and RWA on three dimensions of prejudice using a full cross‐lagged longitudinal sample (N = 127). As expected, RWA, but not SDO, predicted prejudice towards ‘dangerous’ groups, SDO, but not RWA, predicted prejudice towards ‘derogated’ groups, and both RWA and SDO predicted prejudice towards ‘dissident’ groups. Results support previously untested causal predictions derived from the DPM and indicate that different forms of prejudice result from different SDO‐ and RWA‐based motivational processes.

句子加工中的语义P600效应

句子加工领域的研究中,一般认为,N400效应与语义加工有关,句法违反通常引发P600效应。然而近年来一些研究发现,句子语义违反时也引发了P600效应,即语义P600效应。对语义P600效应的诱发原因及其功能意义,目前有三种代表性的解释:监控说认为,P600效应是由语言理解过程中的认知冲突引发的,反映了认知监控系统对可能出现的加工错误的检测与解决;而非句法中心动态模型认为语义P600效应反映的是句子理解过程中两条通路之间出现冲突时的持续分析;扩展的论元依赖模型则用新的句子加工模型来解释语义P600效应,认为语义P600效应与句法违反引发的P600效应产生于句子加工的不同过程。     

由两个模型看视觉工作记忆容量机制的研究

在众多的实验基础上, 研究者提出了分析视觉工作记忆的“容量有限模型”和“资源灵活分配模型”, 而两个模型在以下三方面存在着争论：(1)视觉工作记忆中保存的项目精度是否是固定的, (2)资源分配的模式是连续分配的还是以量子化模式分配的, (3)存储单元是以特征为单元还是以客体为单元。未来该领域的研究应加强对视觉工作记忆容量单元的探讨, 探索应用新的研究方法, 控制影响视觉工作记忆容量的空间因素等。     

药物成瘾理论的新进展

成瘾过程伴随着一系列脑机能和心理机能的改变,但对药物滥用如何导致这些改变以及它们如何诱发成瘾却存在着不同的解释。近年来,由于认知心理学和认知神经科学研究技术在该领域的应用,研究者对药物成瘾过程的认知机能及其脑机制获得了新的认识,且基于对负性生活事件及外部压力在维持药物滥用及诱发复吸行为中的作用的测量学研究和动物实验研究而提出的成瘾理论为该领域的研究开辟了新的思路。本文重点评述了药物成瘾的认知加工模型和以压力或负性情绪为核心的相关理论模型及其研究,并提出进一步研究的方向。
