Go/No-Go范式中非反应手状态对Simon效应性质的影响

为了探讨非反应手对标准Simon任务改装的go/no-go任务的影响,被试只对其中一种颜色进行按键反应,通过指导语来操控非反应手的状态,结果发现：(1)实验一中当不提醒非反应手如何放置时,不会产生Simon效应;(2) 实验二中要求非反应手放在固定的桌面位置上,产生了视觉运动Simon效应,其随反应时的增大而减小;(3) 实验三中要求非反应手放在固定的非反应键上,却产生了认知Simon效应,其随反应时的增大而增大。这说明非反应手的状态影响Simon效应的产生及其性质。     

Verbal social primes alter motor contagion during action observation

We investigated whether prosocial and nonsocial word primes prior to action observation modify subsequent initiation and execution of the observer's own reach-to-grasp actions. Participants observed a model performing exaggeratedly curved (vertical deviation) or natural straight reaches to a vertical dowel and always performed a straight reach to a dowel themselves. Observing curved movements slowed initiation times and increased the vertical deviation of the participants’ movements. Observing curved movements enhanced vertical deviation only in the prosocial word primes condition. We suggest that social context priming can modulate initiation of movement as well as the extent of motor contagion (in this case, the extent of vertical deviation) between model and observer.     

Priming effect in affirmative complex conditional connectives

We report the results of an experiment that examined the mental representations underlying the comprehension of complex conditional connectives (such as “A, on condition that B”) and the conditional if (such as “A, if B”). The mental representations during the comprehension stage were analysed using a “priming methodology”. The experiment showed that participants read the possibility “A and not-B” faster when it was primed by “A, if B” than when it was primed by “A, on condition that B”. The finding suggests that people understand the sentence “A, on condition that B” as biconditional; other possibilities (“A and B”, “not-A and B”, “not-A and not-B”) were primed equally by both connectives. We discuss the implications of this for current theories of reasoning.     

权力具身效应的影响因素及机制

具身认知为人们解读“权力”提供了新的理论基础和方法论,但以往多数研究强调语言层面上权力的概念表征,较少关注权力的社会具身效应。本文通过梳理国内外权力具身认知研究的文献,从情境、文化因素、个体因素等方面分析权力具身效应的影响因素,并揭示身体经验影响权力认知和行为的心理机制和过程——模态启动。在此基础上进一步明确未来的研究方向,应从社会具身效应的作用机制、多重心理机制、权力具身效应的神经机制、应用研究等方面进行深入研究。     

焦虑情绪与启动情绪两种状态下的记忆信息处理

通过2个实验,研究了焦虑情绪和暂时启动情绪状态下被试的记忆信息的处理。实验一,选取100名大学生,研究高焦虑、中焦虑和低焦虑状态下的记忆操作,结果发现,焦虑情绪的水平与积极词语的记忆呈负相关,与消极和中性词语的相关不显著。实验二,选取86名大学生,随机将他们分成愉快启动组、悲伤启动组和对照组,研究启动情绪状态的记忆操作,结果表明,在启动的愉快和悲伤情绪状态,被试对不同类型的词语的记忆没有显著差异。但是2个实验都表明,人们对积极词语和中性词语的记忆数量都显著大于对消极词语的记忆。     

内隐记忆研究的新进展:概念、实验和模型

本文回顾了近年来内隐记忆研究的新进展。内隐记忆概念的描述性和模糊性正受到研究者的批评。对此概念进行更准确地把握在当前愈显紧迫和必要。多数研究者仍继续沿用这一术语．最近的实验研究修改了部分早期结论．并开始与学习和记忆研究的其他领域,尤其是涉及无意识过程的领域互相结合。内隐记忆的解释和建模呈现出从定性到定量的发展趋势。     

情绪启动研究新进展

情绪启动是探讨无意识情绪和态度自动激活的有效方法,其研究对于推动情绪和社会认知领域态度的研究具有重要意义。文章指明了近期研究不仅关注情绪启动的产生条件,而且逐步深化了自身研究并发展了新的范式,同时在研究较为成熟的基础上,运用该范式探讨情绪与认知及社会认知领域的一系列问题。此外,文章简评了厂近期研究中存在的问题并展望了未来研究的方向。     

Antecedent Priming at Trace Positions in Children’s Sentence Processing

The present study examines whether children reactivate a moved constituent at its gap position and how children’s more limited working memory span affects the way they process filler-gap dependencies. 46 5–7 year-old children and 54 adult controls participated in a cross-modal picture priming experiment and underwent a standardized working memory test. The results revealed a statistically significant interaction between the participants’ working memory span and antecedent reactivation: High-span children (n = 19) and high-span adults (n = 22) showed evidence of antecedent priming at the gap site, while for low-span children and adults, there was no such effect. The antecedent priming effect in the high-span participants indicates that in both children and adults, dislocated arguments access their antecedents at gap positions. The absence of an antecedent reactivation effect in the low-span participants could mean that these participants required more time to integrate the dislocated constituent and reactivated the filler later during the sentence.     

目标刺激的熟悉度和呈现角度对情绪启动的影响

本研究初步考察目标刺激的熟悉度和呈现角度对情绪启动的影响。研究采用女性面孔图片作为实验材料,随机选取30名大学生被试进行实验,采用重复测量方差分析对数据进行统计分析。结果发现:当目标刺激为熟悉图片时,出现了情绪启动效应;当目标刺激为不熟悉的图片时,未发现情绪启动效应;目标刺激的呈现角度对情绪启动效应没有影响。     

Implicit semantic perception in object substitution masking

Decades of research on visual perception has uncovered many phenomena, such as binocular rivalry, backward masking, and the attentional blink, that reflect ‘failures of consciousness’. Although stimuli do not reach awareness in these paradigms, there is evidence that they nevertheless undergo semantic processing. Object substitution masking (OSM), however, appears to be the exception to this rule. In OSM, a temporally-trailing four-dot mask interferes with target perception, even though it has different contours from and does not spatially overlap with the target. Previous research suggests that OSM has an early locus, blocking the extraction of semantic information. Here, we refute this claim, showing implicit semantic perception in OSM using a target-mask priming paradigm. We conclude that semantic information suppressed via OSM can nevertheless guide behavior.
