从知觉分心任务看儿童类比推理能力的发展

采用四类图片类比映射任务,考察了知觉分心对90名4岁、5岁、6岁儿童类比推理能力发展的影响,并进一步阐释影响儿童类比推理能力发展的可能机制。四类图片类比映射任务分别为一种关系无分心任务、一种关系有分心任务、两种关系无分心任务和两种关系有分心任务。结果表明：（1）在具备相应知识经验的前提下,知觉分心对儿童类比推理成绩有显著影响,儿童在无分心任务中的表现明显好于知觉分心任务的表现。在无分心条件下,4岁儿童已经开始能够选择关系匹配来正确完成类比推理。错误分析发现知觉分心任务中儿童所犯错误主要是分心错误,而且分心错误随年龄增长呈下降趋势。这表明对知觉分心的抑制控制可能是儿童类比推理能力发展的一个重要影响因素。（2）随着年龄增长,儿童类比推理能力逐渐提高。总体表现为6岁组的成绩显著优于4岁、5岁组的成绩,而4岁组的成绩与5岁组的成绩没有显著差异。5岁可能是儿童能够抑制知觉分心进行类比推理的快速发展期     

不同年级学生执行功能发展水平研究

工作记忆、抑制控制及认知灵活性是执行功能的主要成分。以小学三年级、五年级,初中二年级、高中二年级320名学生为被试,研究了他们执行功能各成分的发展。结果发现:工作记忆广度、抑制控制、认知灵活性的发展随着年级(或年龄)的增长而发展,各年级之间存在显著差异。     

5～9岁儿童对心理过程差异的理解

对心理过程差异的理解是学龄后儿童心理理论发展的一部分。本文主要探讨5-9岁儿童对心理过程差异的理解,即理解两个体在看到同样的物体时思维过程是否相同。采用“思想泡泡”的方法给5岁、7岁、9岁各20名儿童讲述故事,考察故事中人物背景知识的有无、对象的不同(自我-他人/他人-他人)及对象间关系的不同(朋友/陌生人)对儿童判断心理过程差异的影响。结果发现,有无背景信息对儿童理解心理过程差异有显著影响,而故事中对象不同及对象之间关系的不同对儿童理解心理过程差异无显著影响。同时还发现,随着年龄的增长,儿童逐渐意识到两个体的思维过程是不同的且能提供比较充分的解释,对心理过程差异的理解使学龄后儿童对个体独特性有更深的了解。     

Personality and lexical decision times for evaluative words

We studied personality influences on accessibility of pleasant and unpleasant stimuli in a sample of 129 students. Self‐reports and reports by knowledgeable informants on extraversion, neuroticism, approach temperament and avoidance temperament were combined with a go/no‐go lexical decision task that included pleasant, unpleasant and neutral words, and two response modes, manual and vocal. The data were analysed using multilevel modelling. Extraversion and approach temperament predicted faster identification of pleasant words than of neutral and of unpleasant words. Vocal responses took longer than manual responses, but mode of response did not interact with the valence of the words. Copyright © 2009 John Wiley & Sons, Ltd.     

Performance on Stroop‐like assessments of inhibitory control by 4‐ and 5‐year‐old children

The rapid development of an aspect of executive functioning (EF), inhibitory control (IC), between the ages of 3‐ and 5‐years, leads to an increase in a child's capacity to suppress inappropriate responding and therefore activate the necessary resources to carry‐out goal‐directed activity (Psychological Bulletin, 1997, 121 , 65–94). To measure EF in children, tasks administered clinically to adults are adapted. The Day–Night Stroop (DNS) is a pictorial modification of the Stroop Test (Journal of Experimental Psychology, 1935, 18 , 642–662), developed for pre‐literate children. Although suitable as a measure of IC in 3‐ to 4‐year‐old children, ceiling effects have been reported on the DNS in slightly older preschoolers. The present study attempted to overcome this limitation by examining the suitability of two modified versions of the DNS in 4‐ to 5‐year‐old preschoolers. To investigate the executive demands made by both Stroop‐like tasks, their associations with another measure of IC (stop‐signal task) and a measure of working memory were examined. Counter to expectations, no significant association was found in performance between the two Stroop‐like tasks; however, the modified DNS developed in this study showed significant relationships with the other executive tasks. The results are discussed in relation to the different methodologies used by these Stroop measures. Implications of this study suggest that researchers should consider more test‐specific factors when assessing EF in young children. Copyright © 2010 John Wiley & Sons, Ltd.     

The voice of self-control: Blocking the inner voice increases impulsive responding

Philosophers and psychologists have long-debated the notion that the voice in our heads might help us to control our actions. Evidence from a number of lines of research suggests that verbal resources help us to focus attention, providing reason to believe that the inner voice might aid self-control via this capacity. In this study we explored the link between verbal resources and self-control by occupying the inner voice and then assessing behavioral indices of self-control. Participants completed regular and switching versions of the Go/No-Go task while doing verbal or spatial secondary tasks. Compared with the spatial task, doing the verbal task resulted in more impulsive responding, as indicated by a greater tendency to make a ‘Go’ response, a pattern that was accentuated in the switching version of the Go/No-Go. Our results suggest that the inner voice helps us to exert self-control by enhancing our ability to restrain our impulses.     

Relationship between religion and obsessive phenomena

The study examined the relationship between religion and symptoms of psychopathology, particularly obsessive‐compulsive (OC) and scrupulosity symptoms. Religious affiliation, religiosity variables (strength of faith, religious application, the beliefs about God's nature), and cognitive factors (e.g., obsessive beliefs) were studied as predictors of OC and scrupulosity symptoms in 179 non‐clinical participants. The main groups (Catholic, Protestant, and no religion) were not different with regard to measures of wellbeing or symptoms of general psychopathology (depression, anxiety, and stress), but were different with regard to OC symptoms. Consistent with cognitive theory, OC beliefs strongly predicted both OC and scrupulosity symptoms, even when general levels of psychopathology were controlled. Religion bore a less major but significant association with OC phenomena. Religious affiliation (being Catholic) was associated with higher levels of OC symptoms, and higher levels of personal religiosity (strength of faith) were associated with higher levels of scrupulosity.     

The link between belongingness and depressive symptoms: An exploration in the workplace interpersonal context

Interpersonal factors are crucial to a deepened understanding of depression. Belongingness, also referred to as connectedness, has been established as a strong risk/protective factor for depressive symptoms. To elucidate this link it may be beneficial to investigate the relative importance of specific psychosocial contexts as belongingness foci. Here we investigate the construct of workplace belongingness. Employees at a disability services organisation (N = 125) completed measures of depressive symptoms, anxiety symptoms, workplace belongingness and organisational commitment. Psychometric analyses, including Horn's parallel analyses, indicate that workplace belongingness is a unitary, robust and measurable construct. Correlational data indicate a substantial relationship with depressive symptoms (r = ?.54) and anxiety symptoms (r = ?.39). The difference between these correlations was statistically significant, supporting the particular importance of belongingness cognitions to the etiology of depression. Multiple regression analyses support the hypothesis that workplace belongingness mediates the relationship between affective organisational commitment and depressive symptoms. It is likely that workplaces have the potential to foster environments that are intrinsically less depressogenic by facilitating workplace belongingness. From a clinical perspective, cognitions regarding the workplace psychosocial context appear to be highly salient to individual psychological health, and hence warrant substantial attention.     

Distinguishing rumination from worry in clinical insomnia

Research has found that repetitive thought processes, such as worry and rumination, play an important role in several disorders; however, these cognitive processes have not yet been examined in insomnia. This study explores rumination and worry in insomnia by examining: 1) whether those high and low on rumination and worry differ on subjective sleep measures, and 2) whether rumination and worry are distinct processes in insomnia. Participants (N = 242) were diagnosed with an insomnia disorder by sleep experts. Participants completed measures of worry and rumination and maintained a 2-week daily sleep log. Results of a multivariate analysis of variance found no main effect of worry; although high and low ruminators differed on several sleep log indices, including sleep efficiency, wakefulness after sleep onset and sleep quality. Factor analysis supported the idea that rumination and worry are separate constructs. Whereas previous research has focused on worry in insomnia, these findings suggest that rumination is important for understanding sleep disturbance. Further, although rumination and worry are both repetitive thought processes, these results indicate that they are distinct processes within insomnia and should be treated as such. The results are discussed with respect to treatment implications for Cognitive Behavioural Therapy for Insomnia.
