工作记忆与选择性注意的交互关系

综述了近年来工作记忆和选择性注意交互关系的一系列研究。研究者们主要从两个方面对该领域的问题进行了探讨：（1）工作记忆在选择性注意中的作用,主要涉及工作记忆的内容在选择性注意的注意导向中的作用、在晚期反应选择中的作用以及在视觉搜索和返回抑制中的作用等方面;（2）选择性注意在工作记忆的信息维持和更新中的作用,主要涉及空间注意在空间工作记忆的复述机制中的作用、注意的分心物加工机制对工作记忆的影响以及在记忆表征中的选择性注意等方面     

儿童返回抑制的研究进展

返回抑制是视觉选择性注意中的一种抑制现象,是人的一个重要的信息加工机制,是当前认知心理学研究的热点之一,本文主要介绍了近年来婴幼儿和儿童的返回抑制研究的内容和成果。     

干扰、工作记忆与一般流体智力

工作记忆与复杂认知任务之间的关系已成为工作记忆研究领域的热点问题。大量研究表明,工作记忆广度不仅是评价工作记忆能力的一种指标,而且也是衡量一个人的高级认知能力的预报因子。本文从工作记忆的本质以及工作记忆与一般流体智力之问的关系人手,分析了干扰不仅是影响工作记忆容量个体差异的关键因素,而且也在工作记忆与一般流体智力的关系中起着重要的影响作用。     

Is Silence More Golden for Women than Men? Observers Derogate Effusive Women and their Quiet Partners

Couples in which the woman is more verbally disinhibited than the man (man-more-inhibited couples) report lower satisfaction than couples in which the man is more verbally disinhibited (woman-more-inhibited couples). A violation of traditional gender roles is hypothesized to underlie this phenomenon. It was predicted that members of man-more-inhibited couples would be rated less likeable than woman-more-inhibited couples, and disinhibited men would be rated more competent than other males and females. To test these hypotheses, 95 undergraduate participants from a southwestern US university viewed a videotaped conflict between a man-more-inhibited or woman-more-inhibited couple. As predicted, members of man-more-inhibited couples were rated less likeable than members of woman-more-inhibited couples and disinhibited husbands were rated more competent than all other targets.

The role of BIS/BAS in the vulnerability for depression in adolescent girls

Reinforcement Sensitivity Theory (RST), the original (i.e. Gray, 1982) or revised (Gray & McNaughton, 2000), has yet to be used as a framework for investigating vulnerability to Major Depressive Disorder (MDD) in adolescents. The present study employed a high-risk design to examine whether aberrant BIS-FFFS/BAS activity was similarly present in both depressed girls and girls at high risk for depression.MethodsN = 85 age-matched biological daughters of mothers with differential MDD status: (a) MDD (n = 17), (b) high-risk (n = 34), and (c) healthy controls (n = 34) completed measures of the BIS/BAS, depression, and anxiety.ResultsMDD girls scored significantly higher on BIS than healthy controls but not high-risk girls, and the high-risk and control groups did not differ. No group differences were found on BAS or FFFS-Fear.ConclusionsElevated BIS was not identified as a vulnerability factor for MDD; however, it does distinguish depressed adolescents from healthy controls.     

Facets of mindfulness mediate behavioral inhibition systems and emotion dysregulation

Behavioral motivation is regulated through the behavioral inhibition system (BIS) and the behavioral approach system (BAS), which underlie responses to emotional stimuli and are thought to influence emotion dysregulation. Research shows that mindfulness may increase the efficacy of emotion regulation among those with psychological symptoms, but the relationships between behavioral motivation and mindfulness have been only minimally explored. This study examines relationships between behavioral motivation systems and emotion dysregulation as mediated by mindfulness facets. Mediation was tested in a sample of 246 college students (M_age = 19.28, 61.8% female, 81.3% Caucasian) using a multiple mediator bootstrapping method. Results revealed an indirect relationship between BIS sensitivity and increased emotion dysregulation through underutilization of three distinct mindfulness skills: act with awareness, non-judging, and non-reactivity. Mindfulness facets did not mediate relationships between BAS sensitivity and emotion dysregulation, though BAS Reward Responsiveness directly predicted increased emotion dysregulation while BAS Drive was marginally associated with decreased emotion dysregulation. Findings delineate specific relationships between BIS/BAS, mindfulness skills, and emotion dysregulation while suggesting mindfulness training may be useful for BIS sensitive individuals.     

Suppressing the truth as a mechanism of deception: Delta plots reveal the role of response inhibition in lying

Lying takes more time than telling the truth. Because lying involves withholding the truth, this “lie effect” has been related to response inhibition. We investigated the response inhibition hypothesis of lying using the delta-plot method: A leveling-off of the standard increase of the lie effect with slower reaction times would be indicative of successful response inhibition. Participants performed a reaction-time task that required them to alternate between lying and truth telling in response to autobiographical questions. In two experiments, we found that the delta plot of the lie effect leveled off with longer response latencies, but only in a group of participants who had better inhibitory skills as indexed by relatively small lie effects. This finding supports the role of response inhibition in lying. We elaborate on repercussions for cognitive models of deception and the data analysis of reaction-time based lie tests.     

靶子-靶子任务中认知控制对返回抑制的反转

使用冲突色词作为外源性线索,通过3(任务类型)×2(线索有效性)×2(色词一致性)混合设计考察认知控制对返回抑制(IOR)的影响。结果:(1)线索-靶子任务(CT)和靶子-靶子任务(TT)均产生正值IOR,CT的IOR效应量(32ms)显著大于TT(12ms)。(2)线索有效性和任务类型交互作用显著。按键反应组IOR效应量(11.85ms)显著大于颜色反应组(-18.5ms)和词意反应组(-25.65ms)。证实冲突色词在CT任务中做为线索可产生IOR,这种范式上的新尝试同样适用于TT任务。在TT任务中对认知冲突的觉察和控制导致IOR效应反转,支持注意的非盲性机制。研究为主动操纵被试对线索的认知控制程度,考察复杂任务下实施认知控制对注意定向的影响提供了一条可行途径。
