情绪即社会信息模型述评

情绪即社会信息(EASI)模型提出,个体对他人的情绪信息加工具有两种方式:情感反应与推断加工。认识动机水平及不同的社会情境会影响两种加工的强度,进而影响个体的决策。该模型在谈判、领导者和最后通牒、独裁者博弈研究中获得了直接和间接的实证支持。心理理论与移情的新近神经生理研究成果也有助于深入探索该模型的神经生理基础。该模型具有很强的应用潜力,但形成时间尚短,需要进一步探索并应用到实践领域中去。     

动态信息呈现对问题发现的影响研究

在多轮次动态和一次性静态两种呈现方式下,采用出声思维研究20名大学生潜藏与矛盾情境的问题发现特点。研究表明:(1)动态呈现促进被试更全面加工信息,发现问题数量和变通性优于静态呈现,但也阻断信息间的关联,不利于发现跨区问题。(2)动态呈现下,问题均匀分布在每个区域并按轮次先后顺序出现,静态呈现与此相反。(3)被试在新信息呈现后发现的问题分全新、改变方向、改变程度、一致性和联系性五类,潜藏情境中问题与先前信息关联更多。(4)被试对新信息影响做出积极评价。     

时间分层加工研究述评

为了探讨数秒内不同层级时间加工的特性,研究者分别从“时间信息加工”和“信息加工的计时特性”角度开展了一系列研究。Münsterberg (1889)、Michon(1985) 、Lewis 和 Miall(2003) 及Vierodt(1868)从前一角度,分别指出1/3秒、1/2秒、1秒及3秒可能是数秒以内时距加工机制的分界点,分界点以下与以上的加工机制存在差异。P?ppel(1997, 2009)则从后一角度指出限制信息加工过程的两类时间窗,一类时间窗是以20-60毫秒振荡周期运行的高频系统,属于初级整合单元;另一类时间窗主要是处理2-3秒以内事件系列的低频系统,属于高级整合单元。前一类时间窗可以为信息加工整合基本的心理事件,后一类时间窗则是把2-3秒内的心理事件整合为基本知觉单元。基于以往研究的剖析,我们认为1/3秒、1/2秒及1秒等分界点的真伪性尚需进一步验证,并进一步假设40毫秒以内时间不能觉察为时距;40毫秒至3秒之间,随着长度增加,自动化加工减弱,控制性加工增强;3秒以上主要为控制性加工,涉及记忆过程。     

信息的充分性和情绪性对推理的影响：时间压力的调节作用

主要探讨推理中信息相关因素对分析系统与启发式系统的影响。通过两个实验考察信息的充分性和情绪性对突发事件情境下推理的影响。实验1任务无时间压力,结果发现：信息充分性对推理的影响显著,表现为信息越充分,被试推理的逻辑指数越高,更多使用了分析系统;且信息充分时,接受积极信息的被试的信念指数显著增高。实验2任务有时间压力,结果发现：信息的情绪性对推理的影响显著,表现为接受积极信息的被试推理的逻辑指数显著大于接受消极信息组,更多使用了分析系统。两个实验结果表明,信息的充分性主要通过分析系统对推理产生影响,而信息的情绪性可通过双系统影响推理过程,即积极信息在推理时间充裕时促进启发式系统,但在有时间压力下促进分析系统。     

双向背景信息外部锚问题决策的眼动特征

采用正反双向背景信息日常生活外部锚问题,选取64名大学生,运用眼动技术,考察锚值及双向信息对外部锚问题决策的影响。结果发现：高、低锚组锚定效应指数均在0.76以上,且不存在显著差异。回答锚值比较问题时,从锚值向反向信息的眼跳次数和注视时间显著多于向正向信息的眼跳次数和注视时间。回答估计值问题时,从估计值问题向锚值的眼跳次数和注视时间显著多于向双向信息的眼跳次数和注视时间。研究表明,外部锚引起程度较高的锚定效应。反向信息在问题理解及决策中得到更多关注。锚值在回答锚值比较及估计值问题阶段均对决策产生显著影响。支持了选择通达和信息加工负性偏向观点。     

Development of a social emotional information processing assessment for adults (SEIP‐Q)

An expanded self‐report, vignette‐based, questionnaire was developed to assess five components in a social emotional information processing model (SEIP: attribution, emotional response, response valuation, outcome expectancy, response efficacy, and response enactment), first in a population‐based sample (n = 250) and, second in healthy control participants (n = 50) and in those with DSM‐5 Intermittent Explosive Disorder (IED: n = 50). SEIP‐Q vignettes depict, separately, both overtly aggressive and relationally aggressive as well as socially ambivalent scenarios. This expanded SEIP‐Q assessment demonstrated good internal reliability, as well as convergent and discriminant validity, for all five SEIP components. IED participants differed from healthy controls in all SEIP‐Q components. This expanded SEIP‐Q assessment is thus proposed as a reliable and valid method for studying the various stages of SEIP in adult human subjects. Aggr.

Instructed fear learning,extinction, and recall: additive effects of cognitive information on emotional learning of fear

The effects of instruction on learning of fear and safety are rarely studied. We aimed to examine the effects of cognitive information and experience on fear learning. Fourty healthy participants, randomly assigned to three groups, went through fear conditioning, extinction learning, and extinction recall with two conditioned stimuli (CS+). Information was presented about the presence or absence of conditioned stimulus–unconditioned stimulus (CS–US) contingency at different stages of the experiment. Information about the CS–US contingency prior to fear conditioning enhanced fear response and reduced extinction recall. Information about the absence of CS–US contingency promoted extinction learning and recall, while omission of this information prior to recall resulted in fear renewal. These findings indicate that contingency information can facilitate fear expression during fear learning, and can facilitate extinction learning and recall. Information seems to function as an element of the larger context in which conditioning occurs.     

Biased attention retraining in dysphoria: a failure to replicate

The present study replicated Wells and Beevers [(2010). Biased attention and dysphoria: Manipulating selective attention reduces subsequent depressive symptoms. Cognition &; Emotion, 24, 719–728] and examined the longitudinal effects of attentional retraining on symptoms of depression. Dysphoric undergraduate psychology students were randomly assigned into either a neutral or control training condition. Training was administered using a dot-probe task that presented participants with pairs of pictures (of sad and neutral content) that were followed by a probe that participants had to respond to. Training took place over four sessions during a two-week period, followed by a final follow-up session two weeks later. Mood was measured at baseline, post-training, and at follow-up. All participants showed a significant reduction in depressive symptoms throughout the study, F(1.7, 73.55)?=?21.19, p?Cognition &; Emotion, 24, 719–728]. Implications of the findings on research on attentional retraining in the context of depression are discussed.
