权力感对道德困境判断的影响：基于CNI模型的分析

采用道德困境判断的CNI（consequence, norm, inaction）模型,通过两个实验考察权力感对道德困境判断的影响。实验1探讨个人权力感对道德困境判断的影响,结果显示高个人权力感显著增加被试对规则的敏感,促使个体做出道义论的道德判断。实验2考察回忆任务启动的权力感对道德困境判断的影响,发现相对于低权力感启动的被试,高权力感启动的被试在进行判断时更关注行为的结果,对规则更不敏感,这说明启动的权力感促进功利主义的道德判断,抑制道义论的道德判断。结果表明,不同类型的权力感对道德困境判断的影响存在差异。     

父母冲突频率与青少年生活满意度的关系：青少年行为反应的中介作用

父母冲突与青少年的身心健康息息相关。本研究以366名青少年为被试,采用问卷调查法研究父母冲突频率与青少年生活满意度间的关系,以及父母冲突时青少年行为反应在其中的中介作用。结果表明：（1）父母冲突频率显著负向预测青少年生活满意度;（2）青少年的介入行为与生活满意度呈显著正相关,回避行为则与生活满意度呈显著负相关;（3）在主张–回避的父母冲突场景中,青少年的回避行为在父母冲突频率与生活满意度间起到部分中介作用,中介效应占总效应的22.90%。     

Mediating factors in chick social pecking: II. effects of exposure to movement

Unfamiliarity with movement may lead isolated chicks to respond aggressively when tested with live, moving conspecifics. This hypothesis was tested by comparing the number and locus of pecks by isolated chicks to a stationary or moving model of a chick, and to a live chick. In a second test of the hypothesis chicks that viewed a moving object during isolation and chicks isolated without movement were tested with a live con-specific and their number and locus of pecks were compared. Neither experiment supported the hypothesis. Movement alone failed to excite aggressive pecks and prior experience with movement failed to suppress aggressive pecks. In the first experiment imlated chicks treated the live testmate more aggressively than the moving or stationary model. In the second experiment aggressive pecking of chicks was unaffected by prior experience with movement, These fmdmgs do not support the hypothesis that movement excites aggression in isolated chicks. Nonetheless the results focus attention on the generally neglected problem of emotional and motivational states produced by isolation.     

Drug discrimination under concurrent variable-ratio variable-ratio schedules

Pigeons were trained to discriminate 5 mg/kg pentobarbital from saline under concurrent variable-ratio (VR) VR schedules, in which responses on the pentobarbital-biased lever were reinforced under the VR schedule with the smaller response requirements when pentobarbital was given before the session, and responses on the saline-biased key were reinforced under the VR schedule with the larger response requirements. When saline was administered before the session, the reinforcement contingencies associated with the two response keys were reversed. When responding stabilized under concurrent VR 20 VR 30, concurrent VR 10 VR 40, or concurrent VR 5 VR 50 schedules, pigeons responded almost exclusively on the key on which fewer responses were required to produce the reinforcer. When other doses of pentobarbital and other drugs were substituted for the training dose, low doses of all drugs produced responding on the saline-biased key. Higher doses of pentobarbital and chlordiazepoxide produced responding only on the pentobarbital-biased key, whereas higher doses of ethanol and phencyclidine produced responding only on this key less often. d-Amphetamine produced responding primarily on the saline-biased key. When drugs generalized to pentobarbital, the shape of the generalization curve under concurrent VR VR schedules was more often graded than quantal in shape. Thus, drug discrimination can be established under concurrent VR VR schedules, but the shapes of drug-discrimination dose-response curves under concurrent VR VR schedules more closely resemble those seen under interval schedules than those seen under fixed-ratio schedules. Graded dose-response curves under concurrent VR VR schedules may relate to probability matching and difficulty in discriminating differences in reinforcement frequency.     

An examination of the response styles theory of depression in third- and seventh-grade children: a short-term longitudinal study

The goal of this study was to test the response styles theory of depression in a sample of 3rd- and 7th-grade children. In addition, we examined whether the relationship between rumination and increases in depressive symptoms is mediated by hopelessness and low self-esteem. The procedure involved an initial assessment in which depressive symptoms, response styles, hopelessness, and self-esteem were assessed. The procedure also involved a follow-up assessment, 6 weeks later, in which depressive symptoms, hopelessness, and self-esteem were reassessed. Children with a ruminative response style exhibited increases in depressive symptoms over the 6-week period. In addition, the relationship between rumination and increases in depressive symptoms was mediated by both hopelessness and low self-esteem. Last, contrary to our hypotheses, neither distraction nor problem-solving response styles predicted decreases in depressive symptoms over the course of the study.     

Lapses of intention and performance variability reveal age-related increases in fluctuations of executive control

We examine the hypothesis that the efficiency of executive control processes is less stable over time in older than younger adults. An age-related decrease in the efficiency of executive control should result in an increase in performance variability in task conditions requiring the recruitment of executive control processes and not in task conditions requiring minimal involvement of executive control. Performance variability was similar for younger and older adults in task conditions requiring minimal executive control and greater for older than younger adults in task conditions requiring executive control. These and other data are consistent with the proposal that aging is associated with a decrease in the stability of executive control over time.     

共享概念的性质对拥有关系句子情景模型建立的影响

应用扇效应技术探讨共享概念的性质对建构拥有关系情境模型的影响。共包括2个实验,探讨在将“多人买1物”句式中的所购“物品”改变为隐含共同地点信息的“物品”条件下,被试对“多人买1物”拥有行为句式的学习是否表现出扇效应。结果表明,当所购物品隐含的相同地点信息的情况下,“多人买1物”的拥有行为句式无论是否具有明确的地点状语,都如同“1人买多物”的句式一样,没有表现出扇效应,与Radvanskv的研究结果不同。据此认为,只有在共享概念是属于情景模型建构的维度信息的情况下,有共享概念的信息才能整合为同一个情景模型。     

"以病人为中心"医疗服务模式的理念与发展

纵观20世纪医疗服务的发展历程,医疗服务的发展经历了“以疾病为中心”的传统医疗服务模式到“以病人为中心”的新的医疗服务模式的转变;目前,以“以病人为中心”的医疗服务模式已经成为我国现代医院改革与发展的主题。因此,在阐述医疗服务模式变革与发展的基础上,系统论述了“以病人为中心”的医疗服务模式的内涵与特点,新的理念、新的认识,也带来了新的希望,新的医疗服务模式将不断地改善与提高人们的健康状况与生活质量。     

中国大学生的记忆的自我参照效应

记忆的自我参照效应是指记忆材料与自我相联系时的记忆效果优于其它编码条件的现象,这种优势主要体现在以回忆经验为特征的R反应(“记得”)上。西方一些研究表明,自我参照的记忆成绩优于参照母亲的记忆。本研究以中国大学生为被试,得到参照父亲和母亲的记忆与自我参照有同样好的成绩,显著优于参照名人的记忆,并且父母之间无差异。这支持了独立型／依赖型自我概念模型中的东方文化下的自我概念包括父母的观点。     

Substantive unconscious and adjective unconscious: the contribution of Wilfred Bion

The author first provides her readers with a brief summary of some of Freud's ideas, as found throughout his work, on the notion of 'unconscious'. The notion of unconscious as noun is contrasted to the idea of unconscious as adjective, this latter being proposed as a quality, or a state, ever temporary, dynamic, and subject to the constant changes going on in the individual's internal psychic world, as well as to external conditions. After presenting some considerations, the author then contrasts the Kleinian model of the mind to the Freudian, and Wilfred Bion's contribution is discussed at some length. Within Bion's conception of psychic functioning, the model of 'dream' is highlighted and, in this regard, clarifications are sought regarding Bion's view of the unconscious. To conclude, a brief and superficial approximation to the work of Carl Jung is touched upon, although the author admits to knowing little of Jung's positions.
