父母、教师在3～4岁儿童气质与行为问题相关性上的系统性认知差异

为探究父母和教师在儿童气质与行为问题相关性上的认知差异,本研究采用问卷法对114名3～4岁儿童的父母和所在班教师分别进行施测,结果发现：（1）相对父母问卷,教师问卷结果中,活动水平维度与诸行为问题因子系统性地产生了更强烈的相关;（2）教师问卷结果中,反应阈维度与活动水平、多动、不注意-被动等因子显著相关,而父母问卷结果中则不显著。     

Measuring cognitive and psychological engagement: Validation of the Student Engagement Instrument

A review of relevant literatures led to the construction of a self-report instrument designed to measure two subtypes of student engagement with school: cognitive and psychological engagement. The psychometric properties of this measure, the Student Engagement Instrument (SEI), were assessed based on responses of an ethnically and economically diverse urban sample of 1931 ninth grade students. Factor structures were obtained using exploratory factor analyses (EFAs) on half of the dataset, with model fit examined using confirmatory factor analyses (CFAs) on the other half of the dataset. The model displaying the best empirical fit consisted of six factors, and these factors correlated with expected educational outcomes. Further research is suggested in the iterative process of developing the SEI, and the implications of these findings are discussed.     

再生障碍性贫血发病机制的探讨

目前再生障碍性贫血发病机制有如下解释:造血干(祖)细胞缺陷;造血微环境功能缺陷;免疫功能紊乱.这些解释显示着深刻的哲学意义,正确地应用哲学思维将有助于对再生障碍性贫血发病机制的进一步深入研究.     

药物成瘾理论的新进展

成瘾过程伴随着一系列脑机能和心理机能的改变,但对药物滥用如何导致这些改变以及它们如何诱发成瘾却存在着不同的解释。近年来,由于认知心理学和认知神经科学研究技术在该领域的应用,研究者对药物成瘾过程的认知机能及其脑机制获得了新的认识,且基于对负性生活事件及外部压力在维持药物滥用及诱发复吸行为中的作用的测量学研究和动物实验研究而提出的成瘾理论为该领域的研究开辟了新的思路。本文重点评述了药物成瘾的认知加工模型和以压力或负性情绪为核心的相关理论模型及其研究,并提出进一步研究的方向。     

On preferences and doing the right thing: Satisfaction with advantageous inequity when cognitive processing is limited

We examine outcome satisfaction in situations in which people receive better outcomes than comparable other persons. Building on classical and modern social psychological theories, we argue that when reacting to these arrangements of advantageous inequity, judging the advantage is quick and easy as preferences are primary. We further propose that adjusting this appraisal requires cognitive resources as it entails integrating fairness concerns with the initial preference appraisal. Extending the literature on cognitive busyness, we therefore predict that people should be more satisfied with advantageous inequity when cognitive processing is strongly—as opposed to weakly—limited. Findings across several different experimental paradigms support our predictions. Taken together, our findings shed light on the psychological processes underlying the intriguing interplay between egoism- and fairness-based considerations when evaluating outcomes, as well as on more general preference and adjustment processes.     

Differences in the cognitive accessibility of action and inaction regrets

This paper investigates the temporal pattern of experienced regret and provides insight into the underlying factors leading to differential cognitive accessibility of actions and inactions over time. Across three studies, we find increased cognitive accessibility of inactions in the long term with no difference in the accessibility of actions and inactions in the short term. We find support for the depth of impact, breadth of impact, and frequency of thought as explanations for this differential accessibility.     

The relationship between acceptance,fatigue, and subjective cognitive impairment in hematologic cancer survivors

Background/Objective: Cancer and its treatment can have a detrimental impact on psychological well-being. Acceptance as the basis of acceptance and commitment therapy (ACT) has shown beneficial effects on depression and anxiety. However, its relationship to fatigue and cognitive impairment has not been investigated. A protective effect of acceptance may open up a new target for psychological intervention.Method: A cross-sectional postal survey was undertaken. 922 hematological cancer survivors (≥ 2.5 years post diagnosis) were recruited through two regional cancer registries in Germany. Acceptance (AAQ-II), fatigue (BFI) and subjective cognitive impairment (AFI) were assessed.Results: Higher levels of acceptance were negatively associated with fatigue and subjective cognitive impairment (R²= .34 and R²= .26, respectively). The relationship between fatigue and fatigue-related impairment of daily life was weaker for survivors with high acceptance.Conclusions: Acceptance is strongly associated with fatigue and subjective cognitive impairment. ACT may be useful to reduce symptoms of fatigue and subjective cognitive impairment in cancer survivors.     

Cognitive rigidity in patients with depression and fibromyalgia

Background/ObjectiveThe comorbidity of depression and fibromyalgia chronic syndrome has been well documented in the literature; however, the cognitive structure of these patients has not been assessed. Previous results reported variability in cognitive rigidity in depressive patients, the key for this might be the presence of chronic physical pain such as fibromyalgia. The present study explores and compares the cognitive rigidity and differentiation, between patients with depression with and without fibromyalgia syndrome.MethodThirty one patients with depression and fibromyalgia were matched, considering age, sex and number of depressive episodes, with 31 patients with depression but without fibromyalgia diagnosis. Cognitive rigidity and differentiation were measured with the repertory grid technique.ResultsThe results indicated that depressed patients with fibromyalgia presented higher levels of depressive symptoms, greater cognitive rigidity and lower cognitive differentiation than those without fibromyalgia.ConclusionsThe results might inform future treatments to address the cognitive structure of these patients.     

Parents and carers of young people with mental ill-health: What factors mediate the effect of burden on stress?

A substantial body of research has reported negative outcomes due to caregiving, however, little is known about how caring for a young person with mental ill-health impacts on parents and carers. This study aims to examine whether, like carers of older people, they experience elevated levels of caregiver burden and stress. It expands on earlier studies by examining potential mediators of burden and stress, with a specific focus on how activity restriction affects this association. There were 226 Australian parents and carers of young people (12–25 years) experiencing mental ill-health who voluntarily completed a self-report questionnaire reflecting how their young person’s ill-health had affected them over the past month. Hierarchical regression and multiple mediation analyses were conducted to examine the relationship between caregiver burden and stress, and whether adaptive coping, self-efficacy and activity restriction mediated this relationship. Caregiver burden and stress were strongly related, and both activity restriction and self-efficacy mediated their association, with activity restriction having the stronger effect. Strategies aimed at increasing awareness of the impact of activity restriction and encouraging parents and carers to find ways to maintain essential activity may reduce stress, improving mental health and well-being in parents and carers.     

Eight-year-olds,but not six-year-olds,perform just as well as adults when playing Concentration: Resolving the enigma?

Anecdotal reports suggest that children often outperform adults when playing Concentration. This is surprising as cognitive processes tend to develop progressively throughout childhood. To date, very few studies have examined this apparent paradox, and with mixed results. In the present study, the ability of 6-year-olds (n = 34), 8-year-olds (n = 48), and adults (n = 38) to play Concentration was examined in a controlled computer-based setup involving eye tracking. The main dependent variables were the number of moves and time in seconds to finish the first nine (out of 12) matching pairs. The results revealed that while 6-year-olds were outperformed by older children and adults, 8-year-olds performed just as well as adults. It is suggested that Concentration may represent a cognitive challenge rarely encountered in the real world, and when playing Concentration, adults seem to use strategies that are effective in real life situations, but may be less appropriate when playing the game.
