安全基地启动及其脑机制

近几年,安全基地启动已成为拓展依恋理论的重要实验方法。安全启动能够改善情绪及情绪调节策略、增进人际关系、促进自我实现和利他等。安全启动下,研究者得以考察成人依恋与母婴依恋的神经基础及它们之间的区别与联系。该文分析了安全启动实验的不足,如生态效度和重复率不高,应用范围局限,缺乏启动效应持续性的研究等。未来的安全启动研究应突破现有实验室情境研究局限,拓展应用领域,加强对其心理机制与神经机制的探讨等。     

无意识目标对道德取向的调节作用

已有研究表明目标可以在无意识的条件下被激活并自动地引导行为以达成目标,但该过程是否通过调节心理准备状态实现尚不清楚。本研究考察了无意识目标对个体道德取向的影响。实验1通过语义启动方式激活被试的成就目标,结果发现,与未激活任何目标的被试相比,激活了无意识成就目标的被试更偏向功利主义道德取向。实验2激活被试母亲的概念,结果发现这部分被试比对照组更偏向道义主义道德取向。上述结果表明,自动激活的目标可以影响个体的道德取向,使个体面对道德情境时能做出更合适的行为以达成目标。     

Forecasting good or bad behaviour: A non‐transparent test of contrastive responses to cultural cues

Bicultural individuals vary in the degree to which their two cultural identities are integrated – Bicultural Identity Integration (BII). Among Asian‐Americans, for example, some experience their Asian and American sides as integrated (high BII) whereas others experience the two as divided (low BII). Past research on social judgement found that individual differences in BII affect the way biculturals respond to cultural cues or norms in their situation. Asian‐Americans with low BII tend to contrast to the cultural norm (e.g. they exhibit typically American judgements when in Asian cultural situations) rather than assimilate to them, a response observed more among high BII individuals (e.g., they exhibit typically Asian judgements when in Asian cultural situations). Research has interpreted the contrastive response as reflecting implicit identity motives, yet past studies used measures that make cultural differences salient. Conscious awareness of the experimental hypothesis could elicit contrastive responses. The present research assessed forecasts of others' behaviour in which cultural group differences are less obvious: Asians, compared to Westerners, forecast more positive behaviours from others. In three experiments with Asian‐Americans, we found the contrastive response by low BII individuals persisted. They made more positive forecasts after exposure to American versus Asian cultural cues. This suggests that the moderating role of BII on responses to cultural cues is not a matter of demand characteristics or limited to stereotypical cultural differences. Implications for bicultural identity, implicit processes, and organizational behaviour are discussed.

Phonological priming and cohort effects in toddlers

Adult word recognition is influenced by prior exposure to phonologically or semantically related words (cup primes cat or plate) compared to unrelated words (door), suggesting that words are organised in the adult lexicon based on their phonological and semantic properties and that word recognition implicates not just the heard word, but also related words. We investigate the phonological organisation of the toddler lexicon with two experiments using a picture priming technique. Twenty-four month olds showed inhibition of target recognition in related primed trials compared to unrelated primed trials (Experiment 1) and also in related primed trials compared to unprimed trials (Experiment 2). Further analysis of children’s responding found that this inhibition effect was modulated by the cohort and neighbourhood size of the words tested. Overall, the results indicate a lexical basis for the reported effects and suggest that the phonological properties provide an organisational basis for words in the toddler lexicon.     

The role of form and meaning in the processing of written morphology: A priming study in French developing readers

Three visual priming experiments using three different prime durations (60 ms in Experiment 1, 250 ms in Experiment 2, and 800 ms in Experiment 3) were conducted to examine which properties of morphemes (form and/or meaning) drive developing readers’ processing of written morphology. French third, fifth, and seventh graders and adults (the latter as a control group) performed lexical decision tasks in which targets were preceded by morphological (e.g., tablette–TABLE, “little table–table”), pseudoderived (e.g., baguette–BAGUE, “little stick–ring”), orthographic control (e.g., abricot–ABRI, “apricot–shelter”), and semantic control (e.g., Tulipe–FLEUR, “tulip–flower”) primes. Across all groups, different patterns of priming were observed in both morphological and orthographic/semantic control conditions, suggesting that they all process morphemes as units when reading. In developing readers, the processing of written morphology is triggered by the form properties of morphemes, and their semantic properties are activated later in the time course of word recognition. In adults, patterns of priming were similar except that the activation of the form properties of morphemes decreased earlier in the time course of word recognition. Taken together, these findings indicate that French developing readers process both the form and meaning properties of morphemes when reading and support a progressive quantitative change in the development of morphological processing over the course of reading development.     

汉语句子理解中句法启动机制的眼动和ERP研究

语言产生的句法启动效应在近20年得到较深入研究。那么, 语言理解和语言产生中, 句法启动效应具有相同的加工机制吗？近些年, 研究者考察了印欧语系语言理解中的启动效应, 但还存在较多争论。这究竟是句法效应, 还是策略或者语义效应, 是词汇驱动还是词汇独立的？而且, 这是人类语言理解的语系特性还是普遍特性？单独采用行为技术、眼动技术或者ERP技术很难为这些争论提供坚实的实验证据和较深入的理论解释。鉴于此, 本项目拟采用眼动和ERP结合的技术, 从心理学、语言学和认知神经科学等多学科交叉的视角考查汉语句子理解的句法启动效应。通过分析眼动和ERP实验提供的一致性和差异性证据, 本项目力图阐明和揭示汉语句子理解中句法启动效应的认知特点和机制, 检验内隐学习理论和论元结构理论在解释句法启动效应时的适用性。     

与当前任务无关的规则对自动反应激活过程的影响

摘要：本研究致力于探讨自上而下的任务因素对自动反应激活过程的影响。研究包含两个实验,采用掩蔽启动范式,选取字母和数字作为刺激,任务因素为与当前任务无关的处于预备状态的任务规则。实验一初步验证了与当前无关的处于预备状态的任务规则可以影响自动反应激活过程;实验二进一步证明了这种影响具有广泛性,即与当前无关的任务规则所设定的所有刺激系列都可以影响当前任务中的反应启动过程。研究总结论为：与当前任务目的无关、且存在自动刺激-反应联结的其他任务规则也能通过对被掩蔽的启动刺激反应的调节来影响对靶刺激的反应,从而影响启动效应的发生。     

判断框架对时序知觉位置启动效应的影响

研究采用包含两种判断框架（判断刺激出现的先后次序）的时序判断任务探讨了决策偏向对时序知觉位置启动效应的影响。实验结果表明,时序知觉中存在着位置启动效应,而且在两个靶刺激出现时间间隔不同时,被试在“哪个靶刺激先出现”和“哪个靶刺激后出现”两种判断框架下的正确率存在显著差异,但在两个靶刺激同时出现时并没有出现显著的判断框架效应。因此,本研究推测时序知觉位置启动效应的作用机制不仅包括知觉增强加工过程,而且也与认知决策有关,这为反应偏向理论提供了新的支持证据。
