重复线索化和靶子注意定向对返回抑制的影响

在返回抑制范式下 ,利用线索—靶子模式进行了两个实验 ,以大学生为被试 ,以重复线索化次数来操纵线索化阶段的注意 ,以靶子的注意定向来操纵靶子加工阶段的注意 ,探讨注意对返回抑制的影响。实验一采用连续线索化方式 ,发现当靶子为自主性注意定向时 ,线索化次数对返回抑制有显著影响 ,线索化 3次时返回抑制值大于线索化 1次和 2次 ;当靶子为反射性注意定向时 ,线索化次数对返回抑制无影响。实验二采用交叉线索化方式 ,发现线索化次数对返回抑制的影响正好与实验一相反。两个实验一致表明 ,无论是线索化阶段的注意 ,还是靶子加工阶段的注意 ,均对返回抑制有显著影响 ;并且 ,在对返回抑制的影响上 ,二者存在显著交互作用。从而支持注意影响返回抑制的观点。该结果对返回抑制的机制研究有一定意义。     

类别指称对象提取过程的眼动研究

采用眼动记录法,探讨了语篇理解中类别指称对象的可提取性。实验采用3（实验材料：指称对象、非指称对象、特别控制条件）×2（兴趣区：兴趣区1、兴趣区2）×2（工作记忆容量：高、低）3因素混合设计。通过分析第一次注视时间、总的阅读时间和回视次数等眼动指标发现,类别指称对象提取过程中包含激活和抑制两种过程。被试在阅读完上指示表达之后,立即激活了可能的指称对象,但是对非指称对象的抑制却发生在后来的整合过程中;高工作记忆容量的被试能更有效地抑制非指称对象,更容易形成语篇的完整表征,有效提取类别指称对象。     

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.

Assessing students' use of optional online lecture reviews

Online practice quizzes can be used to supplement instruction in the classroom. Such quizzes can engage retrieval practice, thereby improving learning and retention. However, despite their potential benefits, recent work suggests that students typically underutilize online practice quizzes. This article reports an observational classroom study, in which students were provided optional online reviews throughout the semester. The reviews could be accessed in test format, in which students were given multiple-choice questions and provided correct answer feedback, or in read format in which students were given the same questions and were shown the correct answers. Students who used the test format performed better on exams than students who used the read format or did not use the reviews. Nevertheless, the massive majority of the online reviews (approximately 88%) were not completed, highlighting the tendency for students to underutilize optional online reviews.     

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.
