被试自身人手初始状态对心理旋转加工的影响：眼动研

利用眼动追踪技术,探讨在左右手判断任务条件下人手心理旋转加工是否受到被试自身人手初始状态的影响。两个实验的反应时数据和眼动数据均发现：（1）心理旋转加工受被试自身人手初始状态的影响,表现出一致性效应;（2）显著的内旋效应;（3）被试心理旋转加工时注视点取样存在着不均衡性。这些结果表明：在左右手判断任务中,心理旋转加工的对象是被试自身人手的表象,是自我参照的心理旋转,并且内旋效应是由被试对自身人手表象进行旋转时受到人手生理机制约束所致,而不是被试旋转刺激图片的表象由“生理机制约束知识”影响所致

Validation Studies on a Measure of Overall Managerial Readiness for the Chinese

The Overall Managerial Readiness (OMR) scale was first developed as a simple measure of managerial potential for the Chinese workforce. OMR purports to predict managerial performance by assessing a person's attitudes and intention to engage in managerial practices. It consists of 28 forced‐choice statements most of which refer to attitudes and behaviors in a work setting. Three studies together showed that OMR was correlated negatively with neuroticism, and positively with conscientiousness, agreeableness, openness to experience, and extraversion. Notwithstanding, OMR was distinct from the Big Five, and had incremental predictive power on work performance (Study 3). Besides, OMR alone predicted bank managers' productivity (Study 4). Finally, internal consistency and concurrent validity of a Likert version of OMR was ascertained (Study 5).     

Novel-view scene recognition relies on identifying spatial reference directions

Five experiments investigated whether observer locomotion provides specialized information facilitating novel-view scene recognition. Participants detected a position change after briefly viewing a desktop scene when the table stayed stationary or was rotated and when the observer stayed stationary or locomoted. The results showed that 49° novel-view scene recognition was more accurate when the novel view was caused by observer locomotion than when the novel view was caused by table rotation. However such superiority of observer locomotion disappeared when the to-be-tested viewpoint was indicated during the study phase, when the study viewing direction was indicated during the test phase, and when the novel test view was 98°, and was even reversed when the study viewing direction was indicated during the test phase in the table rotation condition but not in the observer locomotion condition. These results suggest scene recognition relies on the identification of the spatial reference directions of the scene and accurately indicating the spatial reference direction can facilitate scene recognition. The facilitative effect of locomotion occurs because the spatial reference direction of the scene is tracked during locomotion and more accurately identified at test.     

ASSESSING OBSERVER ACCURACY IN CONTINUOUS RECORDING OF RATE AND DURATION: THREE ALGORITHMS COMPARED

The three algorithms most frequently selected by behavior‐analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with criterion records to determine observer accuracy. Block‐by‐block and exact agreement algorithms were susceptible to inflated agreement and accuracy estimates at lower rates and durations. The exact agreement method appeared to be overly stringent for recording responding at higher rates (23.5 responses per minute) and for higher relative duration (72% of session). Time‐window analysis appeared to inflate accuracy assessment at relatively high but not at low response rate and duration (4.8 responses per minute and 8% of session, respectively).     

道德信仰危机的成因及其克服

道德信仰是对道德的终极关怀,是理性的非理性存在方式,是人的精神支柱。道德理想主义,制度安排不尽合理,市场经济负面效应以及社会主义低谷是道德信仰危机的重要根源。发展经济,加强制度伦理建设,强化规则意识等克服道德信仰危机的主要措施。     

5～6岁儿童公平分配玩具行为的心理机制

采用实验法和结构访谈法,考察66名5～6岁儿童在幼儿园游戏活动中公平分配玩具行为的心理机制.结果发现:(1)根据在幼儿园分配玩具的过程中的表现,可以把儿童分为三类:公平型儿童、不公平型和不稳定型,每类儿童的自我评价各不相同;(2)对自己做出的公平行为能做出准确的自我评价,而且对假想的不公平行为也能做出正确的自我评价,这是形成稳定的公平行为的重要心理机制,自我概念、自我形象在道德准则的内化过程中起着重要作用.     

中学生连环数运算中的工作记忆资源分配策略

以初一到高三274名中学生为被试,以连环数认知运算为实验材料,对中学生工作记忆资源的分配策略进行了考察,结果表明:中学生工作记忆资源的分配存在多种策略,且具有多样性;外部策略的正确性高于内部策略和内外部结合策略;中学生使用不同策略解决问题的反应时差异显著;以学生的策略选择的百分比和策略的正确率与解题速度为指标综合考察学生的策略选择来看,中学生较倾向于选择正确率较高的策略。
