语篇主题表征在大脑两半球的存贮

使用半视野速示技术和启动—再认探测方法,采用包含两个句子的短语篇作为前行信息、通过主题启动、歧义词启动探测语段阅读时主题表征在大脑两半球的存贮情况,结果发现,无论是主题启动还是歧义词启动,左视野／右半脑和右视野／左半脑对语境相关的目标词反应时间都比不一致目标词更长,说明语段阅读后两半脑对主题表征都有存贮。     

大学生领悟社会支持的影响因素研究

该研究以371名大学生为被试,考察了个体的幸福感、控制感和压力对领悟社会支持的影响。结构方程模型分析的结果显示：个体属性和情境因素都直接或间接影响着大学生对社会支持的理解和评价;个体属性的影响相对比较重要;在情境因素中,累积压力比当前压力的影响更为重要。本研究结果表明,领悟社会支持是在个人属性的作用下,个体在不断应对日常生活压力的过程中形成和发展的。     

不确定性容忍度、损益概率及延迟风险对延迟选择的影响

研究通过两个实验考查了不确定性容忍度及相关变量对延迟选择的影响,其中实验1采用2（不确定性容忍度：高/低）×2（概率水平：高/中）被试间实验设计;研究2将实验任务设定在有延迟风险情景下中等概率水平,采用单因素（不确定性容忍度：高/低）被试间实验设计.实验1结果表明：不确定性容忍度与概率水平存在交互作用：中等概率时,低容忍度个体比高容忍度个体更偏好延迟选择,高概率时,两者的延迟选择无显著差异,都偏好于选择决策.实验2结果表明：在有延迟风险中等概率时,高、低容忍度个体的决策偏好无显著差异,都偏好选择决策.结论：不确定性容忍度对延迟选择存在影响且受概率水平和延迟风险的调节.     

Echoic and retrieval accounts of the long-term modality effect tested using the suffix procedure

The long-term modality effect is the advantage in recall of the last of a list of auditory to-be-remembered (TBR) items compared with the last of a list of visual TBR items when the list is followed by a filled retention interval. If the auditory advantage is due to echoic sensory memory mechanisms, then recall of the last auditory TBR item should be substantially reduced when it is followed by a redundant, not-to-be-recalled auditory suffix. Contrary to this prediction, Experiment 1 demonstrated that a redundant auditory suffix does not significantly reduce recall of the last auditory TBR item. In Experiment 2 a nonredundant auditory suffix produced a large reduction in the last auditory item. Redundancy is not the only factor controlling the effectiveness of a suffix, however. Experiment 3 demonstrated that a nonredundant visual suffix does not reduce recall of the last auditory TBR item. These results are discussed in reference to a retrieval account of the long-term modality effect.     

Psychosocial mediation of religious coping styles: a study of short-term psychological distress following cardiac surgery

Although religiousness and religious coping styles are well-documented predictors of well-being, research on the mechanisms through which religious coping styles operate is sparse. This prospective study examined religious coping styles, hope, and social support as pathways of the influence of general religiousness (religious importance and involvement) on the reduced postoperative psychological distress of 309 cardiac patients. Results of structural equation modeling indicated that controlling for preoperative distress, gender, and education, religiousness contributed to positive religious coping, which in turn was associated with less distress via a path fully mediated by the secular factors of social support and hope. Furthermore, negative religious coping styles, although correlated at the bivariate level with preoperative distress but not with religiousness, were associated both directly and indirectly with greater post-operative distress via the same mediators.     

识别名人与陌生人面孔的功能磁共振成像

探讨名人与陌生人身份判断的脑功能。6名被试参加实验,运用功能磁共振技术采集数据,AFNI软件进行统计处理。实验结果显示,名人面孔身份识别主要激活了额颞区和梭状回等,陌生人面孔识别主要激活了脑岛和梭状回。实验表明,熟悉名人面孔与陌生人面孔识别有其不同的区域;都有梭状回的视觉加工,但是激活的程度不同。     

Screening of personality disorders among chinese college students by Personality Diagnostic Questionnaire-4+

Four thousand eight hundred and eleven students were sampled from 26 universities in 21 cities of China and evaluated using the Personality Diagnostic Questionnaire-4+(PDQ-4+). Results showed that male students obtained significantly higher scores than female students on paranoid, schizotypal, antisocial, narcissistic, passive-aggressive, and depressive personality disorder scales, and lower scores on the borderline scale. Students from rural areas scored higher than those from urban areas on the schizoid, schizotypal, narcissistic, avoidant, compulsive-obsessive, passive-aggressive, and depressive personality disorder scales, and lower on the paranoid and dependent scales. Singleton students obtained significantly higher scores than nonsingletons on paranoid, antisocial and dependent scales, and lower on schizoid, avoidant, compulsive-obsessive, passive-aggressive, depressive scales. Students from single-parent families scored significantly higher on the schizotypal scales; and students from foster families scored significantly higher on the antisocial, passive-aggressive, and depressive scales. Students from poor families scored significantly higher than those from average or wealthy families on schizoid, schizotyal, antisocial, borderline, narcissistic, avoidant, obsessive-compulsive, passive-aggressive, and depressive personality disorders. The results suggest that low family income, low social status, and parental style contribute to the development of personality disorders.     

Exploring learners' self-efficacy, autonomy and motivation toward e-learning

A questionnaire survey was conducted with 116 college students (47 men, 69 women) in Central Taiwan to investigate predictive relationships among four attitudinal variables, perceived self-efficacy, learners' autonomy, intrinsic motivation, and extrinsic motivation toward e-learning. Analysis showed learners' autonomy was predictive of both intrinsic (57% independent variance explained) and extrinsic motivation (61% independent variance explained). Although perceived self-efficacy was not a predictor of intrinsic motivation and extrinsic motivation, it correlated significantly with extrinsic motivation.     

Evidence for auditory feature integration with spatially distributed items

Recent auditory research using sequentially presented, spatially fixed tones has found evidence that, as in vision for simultaneous, spatially distributed objects, attention appears to be important for the integration of perceptual features that enable the identification of auditory events. The present investigation extended these findings to arrays of simultaneously presented, spatially distributed musical tones. In the primary tasks, listeners were required to search for specific cued conjunctions of values for the features of pitch and instrument timbre. In secondary tasks, listeners were required to search for a single cued value of either the pitch or the timbre feature. In the primary tasks, listeners made frequent errors in reporting the presence or absence of target conjunctions. Probability modeling, derived from the visual search literature, revealed that the error rates in the primary tasks reflected the relatively infrequent failure to correctly identify pitch or timbre features, plus the far more frequent illusory conjunction of separately presented pitch and timbre features. Estimates of illusory conjunction rate ranged from 23% to 40%. Thus, a process must exist in audition that integrates separately registered features. The implications of the results for the processing of isolated auditory features, as well as auditory events defined by conjunctions of features, are discussed.
