注意焦点转换中的返回抑制与更新过程有关

从认知过程的角度考察注意焦点转换中的返回抑制产生的原因。两个实验要求被试为三个图形分别保持一个数字。实验1设置两种任务:"提取且更新任务"要求被试每次提取一个图形的数字,并对数字进行更新;"提取任务"要求被试只需提取图形的数字,而无需对数字进行更新。实验2设置"更新任务",要求被试只需更新图形的数字,而无需对数字进行提取。实验同时设置抑制转换类型和控制转换类型,以考察返回抑制现象。结果表明,在"提取且更新任务"和"更新任务"中存在返回抑制现象,而在"提取任务"中未发现返回抑制现象。这说明,注意焦点转换中的返回抑制现象与更新过程有关。     

Psychometric Properties of the Chinese Version of Core Self-Evaluations Scale

This study examines the basic psychometric properties of the Core Self-evaluations Scale (CSES) originally developed by Judge, Erez, Bono and Thoresen. To date, it is the only available instrument that permits a conceptually pure quantification of core self-evaluations. Factor structures, validity, internal reliability were examined for the two Chinese subsamples. The two-factor model was confirmed via exploratory and confirmatory factor analyses. The invariance between students and non-students was supported. The CSES was found to have satisfactory internal reliability and test-retest reliability. The results of the present study are comparable with those obtained in previous work with measures of social support, emotional intelligence and life satisfaction and increase support for the validity of this instrument. The questionnaire can be used in Chinese adults.     

科学发明情境中问题提出的fMRI研究

本研究中, 以76个科学发明问题(36个带有相关的原型, 40个不带有相关的原型)为实验材料,使用功能性磁共振成像(fMRI)技术探讨了科学发明情境中的问题提出以及新近获得的语义对有价值的科学问题提出的启发效应的大脑机制。对有原型提出有价值的科学问题与无原型提出一般问题这两种情况下被试反应的数据进行记录和分析。结果表明两种情况下共同激活的脑区(科学发明情境中问题提出的脑区)为左侧梭状回、左侧内侧额叶、左侧豆状核、右小脑和左侧中央前回。这些共同激活的脑区表明：左侧梭状回也许与各个语句的语义表征有关; 左侧内侧额叶也许与所有语句的整体语义表征以及提出各个语义之间的“问题”有关(左侧豆状核和右小脑配合内侧额叶分别负责控制注意、眼动的指向和注意资源的分配); 左侧中央前回可能负责用语句表述出所提出的语义之间的“问题”。对有原型提出有价值的科学问题和无原型提出有价值的科学问题这两种情况下被试反应的数据进行记录和分析。结果表明有原型提出有价值的科学问题比无原型提出有价值的科学问题显著激活的脑区(科学发明情境中新近获得的语义对有价值的科学问题提出的启发效应的脑区)为左侧楔前叶、左侧额下回、左侧颞中回。这些显著激活的脑区表明：楔前叶与情境记忆的贮存和提取有关; 额中回与认知控制和注意资源的分配有关; 颞中回与新异性原型的成功激活有关。     

Controlled Social Interaction Tasks to Measure Self-Perceptions: No Evidence of Positive Illusions in Boys with ADHD

Studies have suggested that children with Attention-Deficit/Hyperactivity Disorder (ADHD) possess a Positive Illusory Bias (PIB) where they have higher self-perceptions of competence than more objective measures of their competence. However, recent research calls into question the primary methodology of these studies, that is, difference scores. This study investigated the PIB in boys with ADHD within the social domain using a novel methodology that refrains from using difference scores. Eighty-one 8- to 12-year-old boys with and without ADHD completed social interaction tasks where their actual social performance was made comparable, allowing for tests of between-group differences in self-perceptions that do not rely on difference scores. In addition, to examine whether clarity of social feedback moderates the presence of the PIB, the social tasks presented unclear, clear positive, or clear negative feedback. Boys rated how well they performed in each social interaction task, and these ratings were compared between ADHD and non-ADHD groups. Compared to the non-ADHD group, boys with ADHD did not show a PIB in their ratings of performance on the social tasks. There also was no moderation of boys’ ratings by type of feedback received. In contrast, when the PIB was calculated using difference scores based on child and parent ratings of child competence, boys with ADHD showed a PIB compared to boys without ADHD. These findings call attention to the need to re-examine the phenomenon of the PIB using methodologies outside of difference scores.     

经颅直流电刺激在抑郁症治疗中的应用

已有的神经影像学研究成果揭示, 抑郁症发作的重要原因之一是大脑前额叶皮层结构和功能受损。经颅直流电刺激(tDCS)作为一种无创脑刺激, 选取前额叶皮层作为刺激区域, 通过调节皮层兴奋性来治疗抑郁症, 能够有效缓解抑郁症状和改善受损的认知功能, 疗效明显且持久稳定。针对tDCS在抑郁症治疗研究中的问题, 未来可从有效性、个体差异以及预防干预等六个方面进一步研究, 以期tDCS作为一种具有潜力的治疗手段, 在临床上有更为广泛地应用。     

The nose tells it to the eyes: crossmodal associations between olfaction and vision

Crossmodal linkage between the olfactory and visual senses is still largely underexplored. In this study, we investigated crossmodal olfactory-visual associations by testing whether and how visual processing of objects is affected by the presence of olfactory cues. To this end, we explored the influence of prior learned associations between an odour (eg odour of orange) and a visual stimulus naturally associated with that odour (picture of orange) on the movements of the eyes over a complex scene. Participants were asked to freely explore a photograph containing an odour-related visual cue embedded among other objects while being exposed to the corresponding odour (subjects were unaware of the presence of the odour). Eye movements were recorded to analyse the order and distribution of fixations on each object of the scene. Our data show that the odour-related visual cue was explored faster and for a shorter time in the presence of the congruent odour. These findings suggest that odours can affect visual processing by attracting attention to the possible odour source and by facilitating its identification.     

区域刻板印象的激活实验研究

The Attentional Boost Effect: Transient increases in attention to one task enhance performance in a second task

Recent work on event perception suggests that perceptual processing increases when events change. An important question is how such changes influence the way other information is processed, particularly during dual-task performance. In this study, participants monitored a long series of distractor items for an occasional target as they simultaneously encoded unrelated background scenes. The appearance of an occasional target could have two opposite effects on the secondary task: It could draw attention away from the second task, or, as a change in the ongoing event, it could improve secondary task performance. Results were consistent with the second possibility. Memory for scenes presented simultaneously with the targets was better than memory for scenes that preceded or followed the targets. This effect was observed when the primary detection task involved visual feature oddball detection, auditory oddball detection, and visual color-shape conjunction detection. It was eliminated when the detection task was omitted, and when it required an arbitrary response mapping. The appearance of occasional, task-relevant events appears to trigger a temporal orienting response that facilitates processing of concurrently attended information (Attentional Boost Effect).
