具身知觉符号理论视角下的情绪启动效应

从知觉符号理论出发对情绪启动效应进行解读,启动刺激与目标刺激涉及的知觉符号相似性、框架相似性及模态激活延续性是情绪启动效应产生的可能机制和影响因素。在此基础上总结归纳出情绪启动的知觉符号匹配假说,并建构情绪启动效应认知加工模型,对现有情绪启动理论进行整合和拓展,以促进情绪启动刺激材料的拓展、提高研究生态效度; 促进情绪启动效应操作的有效性,进而提高其应用价值。情绪启动研究亦能反哺于知觉符号理论,促进其发展。     

Visual configural processing in adults born at extremely low birth weight

Being born at extremely low birth weight (ELBW; ≤1,000 g) is associated with enduring visual impairments. We tested for long‐term, higher order visual processing problems in the oldest known prospectively followed cohort of ELBW survivors. Configural processing (spacing among features of an object) was examined in 62 adults born at ELBW (M_age = 31.9 years) and 82 adults born at normal birth weight (NBW; ≥2,500 g: M_age = 32.5 years). Pairs of human faces, monkey faces, or houses were presented in a delayed match‐to‐sample task, where non‐matching stimuli differed only in the spacing of their features. Discrimination accuracy for each stimulus type was compared between birth weight groups, adjusting for neurosensory impairment, visual acuity, binocular fusion ability, IQ, and sex. Both groups were better able to discriminate human faces than monkey faces (p < .001). However, the ELBW group discriminated between human faces (p < .001), between monkey faces (p < .001), and to some degree, between houses (p < .06), more poorly than NBW control participants, suggesting a general deficit in perceptual processing. Human face discrimination was related to performance IQ (PIQ) across groups, but especially among ELBW survivors. Coding (a PIQ subtest) also predicted human face discrimination in ELBW survivors, consistent with previously reported links between visuo‐perceptive difficulties and regional slowing of cortical activity in individuals born preterm. Correlations with Coding suggested ELBW survivors may have used a feature‐matching approach to processing human faces. Future studies could examine brain‐based anatomical and functional evidence for altered face processing, as well as the social and memory consequences of face‐processing deficits in ELBW survivors.     

视觉信息加工中的整体优先性

该文综述了视知觉的整体优先性理论,以及关于整体优先性机制的理论及其面临的困难,特别介绍了本文作者近年来开展的一系列关于整体优先性的行为和事件相关电位研究结果,以及根据这些结果提出的一个基于知觉组织和选择性注意相互作用的复合刺激加工的理论模型。     

不同作业阶段的分配注意对返回抑制的影响

在双作业条件下,利用线索－靶子模式进行了两个返回抑制实验,实验一应用简单分心刺激,实验二应用复杂分心刺激。两个实验均在呈现阶段或／和靶子呈现阶段安排分心作业,以大学生为被试,其主作业为觉察星号,尽快按键作出反应。结果表明：（１）在简单分心作业条件下,返回抑制依然存在,但数值减少,在复杂分心作业条件下,返回抑制全部消失。（２）无论分心作业如何,线索呈现阶段或／和靶子呈现阶段的分散注意对返回抑制所产生     

权力概念垂直空间隐喻表征激活的条件

本研究通过三个实验考察权力概念垂直空间隐喻表征激活的条件。实验1发现,在权力判断任务中,具有直接权力关系的相关词对和间接权力关系的无关词对都可以激活隐喻表征。实验2使用相关判断任务,只有相关词对激活了隐喻表征。这说明对词汇进行语义加工并理解权力关系是激活隐喻表征的重要条件。实验3引入水平方向干扰,并将被试的注意转移到干扰信息上,结果仍然出现了隐喻一致性效应,表明垂直空间线索不是隐喻表征激活的必要条件。

空白间隔对汉字知觉干扰效应的影响

采用辨认残缺汉字的方法考察空白间隔对汉字知觉干扰效应的影响。两个实验分别考察了空白间隔的长短和不同的插入位置对汉字知觉干扰效应的影响,结果发现:(1)适当长度的空白间隔(大于等于600ms)能导致干扰效应的消失;(2)该空白间隔的位置越接近递进进程最后阶段,残缺汉字的辨认成绩越好,越不容易出现干扰。实验结果支持竞争激活假说,不支持失匹配假说。     

Reply to Kurth,Crosby, and Basse’s review of Emotions,Values, and Agency

In this reply, I argue that the worries raised by Kurth and this coauthors are not fatal for the perceptual theory of emotions. A first point to keep in mind in discussing the analogy argument in favor of that account is that what counts is the overall balance of similarities and differences, given their respective weight. In any case, I argue that none of the alleged differences between sensory perceptual experiences and emotions are such as to rule out that emotions are a kind of perceptual experience which can confer epistemic justification of our evaluative beliefs. Finally, I suggest that the perceptual theory is in a position to nicely capture what happens when we disagree about evaluative issues.     

语言和情境对具体概念感知运动仿真的影响

具体概念加工中的感知运动仿真是概念表征的核心加工过程。本研究系统探讨了语言因素(语言类型：第一语言和第二语言)和情境因素(知觉情境：空间知觉情境和语义知觉情境)对具体概念加工中感知运动仿真的影响。实验1采用语义相关判断范式探讨了第二语言加工过程中是否存在感知运动仿真, 以及第二语言中的仿真和第一语言中的仿真是否存在差异。研究发现, 第二语言加工中依然存在感知运动仿真, 但是第一语言的感知运动仿真具有一定的优势。实验2采用语义相关判断范式及其变式, 通过2个分实验分别探讨了个体加工概念时空间知觉信息和语义知觉信息对于概念表征过程中感知运动仿真的影响。研究发现, 无论是在较弱的空间信息知觉条件下还是在较浅的语义信息知觉条件下, 具体概念加工过程中都产生了感知运动仿真。本研究的发现弥补了知觉符号理论未对第二语言中的感知运动仿真提出针对性预测的不足, 表明感知运动仿真具有一定的跨语言稳定性。同时, 具体概念加工中的感知运动仿真不受空间信息和语义信息的调节, 这表明感知运动仿真能在一定程度上自动化产生。
