个体差异对工作记忆训练迁移效果的调节

本研究考察了流体智力基线水平对工作记忆训练迁移效果的影响。采用前后测设计,以视觉和听觉双任务n-back作为工作记忆训练任务,对训练组进行为期一个月的训练;积极对照组采用阅读任务进行训练。结果发现积极控制组的流体智力水平在基线与后测之间无显著变化;而训练组流体智力水平在后测时与基线相比有显著提高,且工作记忆训练提升量越大的个体其流体智力改善越大。说明认知训练有效迁移到了流体智力水平的改善上。我们还发现流体智力基线水平调节了工作记忆训练对流体智力水平的迁移,即工作记忆训练提升量越大,流体智力改善值越大,对于那些流体智力基线水平较高的人来说,工作记忆训练对流体智力改善的效果更大。流体智力基线水平、工作记忆训练提升量及两者的乘积共同影响了流体智力改善值。这一结果表明个体差异如流体智力基线水平可以调节工作记忆训练对流体智力水平的迁移。     

姓名对个体心理与行为的实际影响：证据和理论

姓名不仅会影响他人的印象与评价, 还可能会影响个体实际的心理与行为。近几十年来, 心理学家在决策、成就、健康、人格四个领域开展了大量实证研究来考察姓氏或名字对个体的实际影响。姓名的多个维度(如独特性、性别倾向、含义效价、温暖-能力维度等)在不同程度上可以预测这些领域的心理与行为(包括职业决策/生活决策/经济决策、职业成就/学业成就、生理健康/心理健康/犯罪行为、人格特质/心理需要/面孔特征等)。但是, 现有研究证据比较混杂, 理论解释有待完善。未来研究应全面考虑姓名维度, 重点解决可重复性、因果关系、心理机制、跨文化普遍性等问题, 努力构建更系统、更包容的理论来解释姓名的心理与行为效应。     

Japanese and British Children's Understanding of the Social Function of Pretend Crying

The purpose of this study was to investigate cross-cultural differences in children's understanding of pretend crying. Five- and 6-year-olds from Japan and the United Kingdom (N = 71) heard two hypothetical stories in which the protagonist of each story pretended to cry in front of another person. Children were asked about the appearance–reality distinction of pretend crying, the other character's thoughts and behavior, and the children's own moral judgment of pretend crying. Cultural differences were found in their understanding of the social function of pretend crying. Japanese children judged that pretend crying elicited another's concern and prosocial behavior more than British children. There were no significant differences in appearance–reality distinction or moral judgments between Japanese and British children. All participants successfully discriminated between pretend crying and real crying, and most participants judged pretend crying as “not good” behavior. These results suggested that Japanese children might be more expected to be sensitive to others’ feelings, and that such cultural differences in communication and socialization lead to different patterns in expectations of the social consequences of pretend crying.     

不同性．别的非吸烟COPD患者肺功能和疾病严重程度的比较

比较不同性别的非吸烟的COPD患者的肺功能和疾病严重程度。选择承德医学院附属医院门诊就诊的非吸烟的稳定期COPD患者93例,其中男性34例,女性59例。对两组患者的肺通气功能和弥散功能,过去一年的急性加重次数、改良的呼吸困难评分及疾病严重程度进行比较。非吸烟的COPD患者男性组和女性组在FEVl％pred,FVC％pred,PEF％pred,FEF25—75％pred,FEF25％pred,FEF75％pred,DOSE评分方面比较,差异有统计学意义（P〈0．05）;在DL—CO％pred和Raw％pred方面比较,差异无统计学意义（P〉0．05）。非吸烟的女性COPD患者较男性COPD患者肺通气功能和小气道功能差,疾病严重程度重,可能与女性患者对生物燃料、空气污染等危险因素易感有关。     

Object-based and egocentric mental rotation performance in older adults: The importance of gender differences and motor ability

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability.     

聋人与听力正常人拓扑性质差异知觉的比较实验研究

分别选取15名聋人与15名听力正常人被试,在两种刺激图对呈现时间条件下,通过考察其对拓扑性质等价和拓扑性质差异图对的反应,本研究对聋人与听力正常人的拓扑性质差异知觉进行了比较研究。研究结果表明:(1)两种呈现时间条件下,被试对拓扑性质等价图对的反应均优于拓扑性质差异图对。(2)对于拓扑性质等价图对,被试在两种呈现时间条件下的反应不存在显著差异;而对于拓扑性质差异图对,被试则对长时间呈现的反应优于短时间呈现。(3)聋人与听力正常人在两种呈现时间条件下对两类刺激图对的反应均不存在显著差异。(4)对于聋人来说,刺激图对长时间呈现和短时间呈现的反应不存在显著差异;而对于听力正常人来说,刺激图对长时间呈现的反应则优于短时间呈现。

A model for the time-order error in contrast discrimination

Trials in a temporal two-interval forced-choice discrimination experiment consist of two sequential intervals presenting stimuli that differ from one another as to magnitude along some continuum. The observer must report in which interval the stimulus had a larger magnitude. The standard difference model from signal detection theory analyses poses that order of presentation should not affect the results of the comparison, something known as the balance condition (J.-C. Falmagne, 1985, in Elements of Psychophysical Theory). But empirical data prove otherwise and consistently reveal what Fechner (1860/1966, in Elements of Psychophysics) called time-order errors, whereby the magnitude of the stimulus presented in one of the intervals is systematically underestimated relative to the other. Here we discuss sensory factors (temporary desensitization) and procedural glitches (short interstimulus or intertrial intervals and response bias) that might explain the time-order error, and we derive a formal model indicating how these factors make observed performance vary with presentation order despite a single underlying mechanism. Experimental results are also presented illustrating the conventional failure of the balance condition and testing the hypothesis that time-order errors result from contamination by the factors included in the model.     

Traces of Identity In Deleuze’s Differential Ontology

Abstract

Deleuze’s differential ontology is a sustained attempt to think and affirm difference as opposed to the unity of identity he insists philosophical thought has tended to privilege. However, by distinguishing between three senses of identity, termed identity of the identical, same, and common, I show that, while Deleuze’s differential ontology offers a powerful critique of identity in the senses of the identical and same, at numerous points in his analysis, such as the virtual-actual movement, the transcendental conditions defining different forms of thinking, and the relationship between the forms of thinking, it appears Deleuze’s affirmation of difference depends on identity in the sense of the common. Rather than using these instances to offer a critique of Deleuze’s differential ontology, I follow his exhortation to read a philosopher creatively and suggest that distinguishing between three senses of identity reveals the complexity of the difference-identity relationship and acts as a stimulus to rethinking this relationship.     

Mechanisms of change in cognitive behavioral therapy for panic disorder: The unique effects of self-efficacy and anxiety sensitivity

The present study examined temporal dependencies of change of panic symptoms and two promising mechanisms of change (self-efficacy and anxiety sensitivity) during an 11-session course of cognitive-behavior therapy (CBT) for Panic Disorder (PD). 361 individuals with a principal diagnosis of PD completed measures of self-efficacy, anxiety sensitivity, and PD symptoms at each session during treatment. Effect size analyses indicated that the greatest changes in anxiety sensitivity occurred early in treatment, whereas the greatest changes in self-efficacy occurred later in treatment. Results of parallel process latent growth curve models indicated that changes in self-efficacy and anxiety sensitivity across treatment uniquely predicted changes in PD symptoms. Bivariate and multivariate latent difference score models indicated, as expected, that changes in anxiety sensitivity and self-efficacy temporally preceded changes in panic symptoms, and that intraindividual changes in anxiety sensitivity and self-efficacy independently predicted subsequent intraindividual changes in panic symptoms. These results provide strong evidence that changes in self-efficacy and anxiety sensitivity during CBT influence subsequent changes in panic symptoms, and that self-efficacy and anxiety sensitivity may therefore be two distinct mechanisms of change of CBT for PD that have their greatest impact at different stages of treatment.
