动态性对简笔画动物审美的影响及其神经机制

运用行为和fMRI技术, 通过比较动态刺激与静态刺激审美判断的行为和脑机制的异同探讨动态性对简笔画动物审美的影响, 包括两个实验。结果发现, 动态简笔画动物的美观程度评分和喜欢程度评分都显著高于静态简笔画动物。同时, 动态简笔画动物审美判断激活的区域基本涵盖了静态简笔画动物审美所激活的区域, 二者都激活了枕叶区等视觉加工区域、额叶区等认知加工区域、眶额叶皮层等奖赏区域以及海马、脑岛、扣带回、杏仁核等情绪加工区域。与静态简笔画动物的审美相比, 动态简笔画动物的审美显著激活了双侧舌回、双侧MT。本研究结果表明, 动态性影响了对简笔画动物的审美, 动态简笔画动物比静态简笔画动物被判断为更加美观。     

时间与金钱概念对消费者购买决策的不同影响及其心理机制

时间与金钱是影响人们消费行为决策的两种不同的重要资源。消费者在进行产品购买时, 常常会受到商家广告语和购物环境中所隐含的时间或金钱概念的影响, 从而做出不同的决策。具体而言, 时间与金钱概念会对消费者的购前决策、购中决策及购后决策三个方面产生不同的影响。从双加工理论的角度来看, 产生这种不同影响背后的心理机制在于时间与金钱概念启动了个体不同的认知加工方式和思维定势, 进而影响了消费者不同的购买决策。未来的研究方向有：(1)细化时间和金钱概念启动对消费者购买决策的不同影响; (2)考虑时间与金钱的权衡对购买决策的影响; (3)进一步探究时间和金钱概念的激活对购前决策的不同影响; (4)探讨时间概念与金钱概念对购买决策不同影响的神经机制。     

冲动性特质对高中生自杀意念的影响:校园排斥与生命意义感的作用

采用冲动性特质量表、青少年遭受校园排斥问卷、生命意义感量表、自杀意念量表对633名高中生进行调查。结果表明:(1)冲动性特质对高中生自杀意念有显著的正向预测作用;(2)校园排斥在冲动性特质与高中生自杀意念间起部分中介作用;(3)冲动性特质经由校园排斥影响高中生自杀意念的中介作用受生命意义感的调节,随着生命意义感的增加,校园排斥对自杀意念的效应逐步减弱。冲动性特质可以通过校园排斥增加高中生自杀意念强度,而生命意义感能有效降低校园排斥对自杀意念的消极影响。     

Chinese Proverb Scale: Development and validation of an indigenous measure of Chinese traditional values

The aim of this study was to develop and validate an indigenous measure of Chinese traditional values using Chinese proverbs. A sample of 363 Mainland Chinese undergraduates participated in Study 1, in which a 26‐item Chinese Proverb Scale (CPS) was developed through factor analysis on an initial pool of 118 Chinese proverbs. Four factors were clearly identified: (a) Diligence, (b) Integrity, (c) Self‐Preservation, and (d) Self‐Interest. The CPS showed satisfactory convergent validity with personal values (S. H. Schwartz, 1992, Advances In Experimental Social Psychology, San Diego, Academic Press) and social axioms (K. Leung et al., 2002, Journal of Cross‐Cultural Psychology, 33, p. 286). For incremental validity, the CPS predicted life satisfaction beyond the Big Five personality, personal values, and social axioms. In Study 2, a sample of 239 Mainland Chinese participants completed the CPS across two measurement occasions with an interval of 6 months. Longitudinal structural equation modeling (SEM) revealed the structure of the CPS was robust and invariant over time. In Study 3, a sample of 167 Chinese undergraduates from Hong Kong responded to an adapted version of the CPS. Multigroup SEM showed structural equivalence of the scale across the mainland and Hong Kong samples. The cultural origins of the factors in the CPS and future applications of the scale in various research areas are discussed.     

Valence evaluation with approaching or withdrawing cues: directly testing valence–arousal conflict theory

The valence–arousal conflict theory assumes that both valence and arousal will trigger approaching or withdrawing tendencies. It also predicts that the speed of processing emotional stimuli will depend on whether valence and arousal trigger conflicting or congruent motivational tendencies. However, most previous studies have provided evidence of the interaction between valence and arousal only, and have not provided direct proof of the interactive links between valence, arousal and motivational tendencies. The present study provides direct evidence for the relationship between approach–withdrawal tendencies and the valence–arousal conflict. In an empirical test, participants were instructed to judge the valence of emotional words after visual–spatial cues that appeared to be either approaching or withdrawing from participants. A three-way interaction (valence, arousal, and approach–withdrawal tendency) was observed such that the response time was shorter if participants responded to a negative high-arousal stimulus after a withdrawing cue, or to a positive low-arousal stimulus after an approaching cue. These findings suggest that the approach–withdrawal tendency indeed plays a crucial role in valence–arousal conflict, and that the effect depends on the congruency of valence, arousal and tendency at an early stage of processing.     

Reevaluating the two-representation model of numerical magnitude processing

One debate in mathematical cognition centers on the single-representation model versus the two-representation model. Using an improved number Stroop paradigm (i.e., systematically manipulating physical size distance), in the present study we tested the predictions of the two models for number magnitude processing. The results supported the single-representation model and, more importantly, explained how a design problem (failure to manipulate physical size distance) and an analytical problem (failure to consider the interaction between congruity and task-irrelevant numerical distance) might have contributed to the evidence used to support the two-representation model. This study, therefore, can help settle the debate between the single-representation and two-representation models.     

共情与青少年内外化问题的关系及影响机制

内外化问题是青少年最常见的心理行为问题,共情与青少年内外化问题具有重要联系,但以往研究青少年内外化问题的时候不注重共情不同成分的区分;即使区分了共情的不同成分,认知共情和情绪共情作为共情的不同成分和内外化问题的关系仍旧存在一定争议,且共情对内外化问题影响的机制鲜有探讨。本文首先综述了认知共情和情绪共情与青少年内外化问题的关系,并借助共情的发生过程（自我-他人模型）理论、发展过程（风险性发展模型）理论和相关神经生理因素,为理解共情对青少年内外化问题的影响机制提供了解释。未来研究可明确共情的定义,发展更生态化的测评方式,并进一步探索影响因素及机制,结合和关注个体特点、特殊群体及文化背景,以便为揭示共情与青少年内外化问题构建更系统的理论。     

急性疼痛与慢性疼痛对奖赏加工的影响及神经机制

疼痛和奖赏能够为个体提供不同的行为动机和主观价值体验,寻求奖赏和避免疼痛对于生存都很重要。疼痛可划分为急性疼痛和慢性疼痛,奖赏可区分为预期阶段的动机成分和体验阶段的享乐成分。奖赏对疼痛的抑制作用已经被广泛证实,但关于疼痛对奖赏的影响,目前的研究结果并不一致。因此需要进一步区分并探究急性疼痛与慢性疼痛对奖赏加工不同阶段的影响,分析两种疼痛对奖赏加工产生不一致影响的现象。这种现象出现的原因可能与急性疼痛向慢性疼痛转变过程中出现的奖赏加工能力缺陷有关。未来可以考虑从改善奖赏加工能力缺陷的角度进行检测和治疗,提前预防急性疼痛向慢性疼痛转变。
