面孔认知研究表明, 人们识别和再认自己所属群体(如种族、性别、年龄)面孔的成绩显著好于识别其他群体面孔的成绩。近年来围绕面孔识别的这种自我群体偏向进行了实验研究, 研究者提出了知觉经验说和社会认知论两种理论来解释其认知加工机制, 而类别化-个性化模型和双路径模型则是将两种理论分别加以整合提出的新解释。研究者还对面孔识别自我群体偏向的神经机制进行了研究, 探讨了评价者、评价对象和评价任务等因素对自我群体偏向的影响。提升面孔识别自我群体偏向研究的生态效度, 构建整合性理论模型以及加强跨文化和本土研究是未来研究的重要方向。 相似文献

密集追踪数据通常蕴含了心理过程的详细变化信息,反映了某些心理的复杂变化过程。时变效应模型用函数替代恒定的系数,可描述密集追踪数据中随时间推移心理的动态变化过程和时变效应,是分析复杂心理过程的有效方法。在介绍时变效应模型的原理后,通过模拟研究考察模型的表现,结果显示:(1)样本量增加可降低函数估计的误差;(2)惩罚样条法的节点数选择与函数的复杂度有关,函数越复杂,所需节点越多;(3)样本量与节点数对函数估计误差的交互效应不显著。进一步应探讨测量次数、数据分布形态、数据缺失等如何影响模型的表现。 相似文献

中国性少数群体普遍存在严重的心理健康问题,家庭是其最大的压力来源。在性少数压力模型的背景下,本研究基于Bifactor模型探究父母消极教养方式对中国性少数(LGB)心理健康的特殊影响。采用父母教养方式问卷、抑郁-焦虑-压力量表和金赛量表对649名LGB进行网络问卷调查,结果发现:(1)父母消极教养方式的Bifactor模型存在部分差异;(2)对于LGB心理健康,父母消极教养方式的一般因子和拒绝特殊因子具有损害作用,过度保护特殊因子具有保护作用。 相似文献

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。 相似文献

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. 相似文献

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。 相似文献

"以病人为中心"医疗服务模式的理念与发展 总被引:25,自引:1,他引:24
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。 相似文献

Numerous previous investigators have explained species differences in spatial memory performance in terms of differences
in foraging ecology. In three experiments we attempted to extend these findings by examining the extent to which the spatial
memory performance of echidnas (or "spiny anteaters") can be understood in terms of the spatio-temporal distribution of their
prey (ants and termites). This is a species and a foraging situation that have not been examined in this way before. Echidnas
were better able to learn to avoid a previously rewarding location (to "win-shift") than to learn to return to a previously
rewarding location (to "win-stay"), at short retention intervals, but were unable to learn either of these strategies at retention
intervals of 90 min. The short retention interval results support the ecological hypothesis, but the long retention interval
results do not.

Lister hooded rats were trained on a forced-sample T-maze alternation task in an environment lacking spatial landmarks. An
early study of spontaneous alternation on the T-maze had shown that rats use a "spatial sense" to select alternate maze arms
across mazes. As this phenomenon may provide a useful tool for studying the neural substrates of a directional sense, we wished
to confirm this finding on a different version of the T-maze task, with well-trained animals. We found that rats successfully
selected the appropriate maze arm when the choice phase of the task was presented on a second maze, oriented in the same direction,
and located in an adjacent room. However, choice performance fell to chance level when the second maze was oriented 90° relative
to the first. This result suggests that the rats do not simply alternate turns across the two environments, but rather that
they rely on a sense of direction that is carried across environments.

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. 相似文献
