Cortical maps for hearing and egocentric selection for self-organization

The auditory cortex of the mustached bat shows complex multiple frequency maps, because cortical neurons in several areas are tuned to particular combinations of signal elements. Different types of combination-sensitive neurons form computational maps in which information-bearing parameters for echolocation (biosonar) are represented systematically. Neuronal response properties and multiple-frequency and computational maps were considered to be created solely by divergent-convergent interactions of neurons in the 'ascending' system. However, we have found that the 'corticofugal' system also plays an important role. Neurons in an iso-best frequency (or echo delay) 'minicolumn' of the auditory cortex augment the auditory responses of subcortical neurons tuned to that frequency (or echo delay) and sharpen their tuning. At the same time, they reduce the response and shift the tuning of subcortical neurons tuned to other frequencies (or echo delays) away from the best frequency (or delay) of the cortical neurons. Cortical neurons mediate a highly focused positive feedback, incorporated with widespread lateral inhibition, via corticofugal projections. This 'egocentric selection' is expected to play an important role in self-organizing the central auditory system.

小学儿童合取概念的形成及其与元认知的关系

采用个别访谈与问卷相结合的方法．研究了小学四、五、六年级共48名儿童合取概念的形成及其元认知的发展。结果表明．小学儿童形成合取概念的能力发展既具有渐进性,又有不均衡性;其元认知知识水平和元认知监控能力的发展均呈现出稳中有变的趋势;各年级的元认知能力与形成合取概念的步数之间均存在非常显著的相关。     

初级指挥官人格类型与PM领导行为类型有效性的关系

通过对陆军初级指挥官人格心理类型与领导行为有效性的心理学研究 ,探讨个人的领导潜能、人格心理类型对领导行为有效性的影响。研究发现 :1方差分析表明 ,具有不同领导行为的指挥官在人格维度上存在明显的统计学差异。提示了指挥官的领导行为取向与人格因素有密切的关系。2卡方分析结果也表明 ,PM型行为的军官在其人格特征上具有“ESTJ”组合特征 ,而 pm型的军官则正好相反 ;另外 ,pm型的军官在成就动机上获得高分的人数最少。3系统聚类分析显示 ,“成就动机”、“感觉”和“判断”三种人格因素与军事指挥官完成整体领导职能有着更为密切的关系。     

Models and theories I: The semantic view revisited

The paper, as Part I of a two‐part series, argues for a hybrid formulation of the semantic view of scientific theories. For stage‐setting, it first reviews the elements of the model theory in mathematical logic (on whose foundation the semantic view rests), the syntactic and the semantic view, and the different notions of models used in the practice of science. The paper then argues for an integration of the notions into the semantic view, and thereby offers a hybrid semantic view, which at once secures the view's logical foundations and enhances its applicability. The dilemma of either losing touch with the practice of science or yielding up the benefits of the model theory is thus avoided.     

Adjusting Social Inferences in Familiar and Unfamiliar Domains: The Generality of Response to Situational Pragmatics

Two experiments investigated the influence of situational pragmatics on the selective use of specific instances and generalized knowledge structures to make social inferences. In Experiment 1, social inferences were made in an unfamiliar domain similar in structure to a typical situation of social greetings and address, but devoid of useful cues to social schemas. Participants were told that either one or another of the features of the situation was more pragmatically important for deriving inferences about appropriate social behaviour; consistent with predictions from a computational model of analogical mapping (ACME), they made reliable inferences based on analogies to specific instances, with the situational importance of relations guiding the selection of the optimal analogue. In Experiment 2, social inferences were examined in the more familiar domain of predicting social behavior between low and high status persons and between members of an ingroup and an outgroup in Japan. The availability of specific examples was varied, as was the perceived importance of status and group membership. The situation was isomorphic to that in the first experiment, except for the availability of generalized knowledge structures to guide inferences. Participants made relatively veridical inferences that were sensitive to variations in the pragmatic importance of dimensions. Provision of specific analogues had little impact on inferences, suggesting that participants were relying instead on more general and cross-culturally applicable knowledge about adjusting social relations according to situational pragmatics.     

Social Dominance Orientation, Hierarchy Attenuators and Hierarchy Enhancers: Social Dominance Theory and the Criminal Justice System

This study investigated differences in social dominance orientation between incumbents of different social roles (police officers vs. public defenders) and ethnic groups known to differ in general social status (i.e., whites vs. blacks and Hispanics). Consistent with theoretical expectations: (a) Police were significantly more social-dominance oriented than either jurors or public defenders. (b) Public defenders tended to be less social-dominance oriented than jurors. (c) Euro-Americans were significantly more social dominance oriented than Afro- and Hispanic-Americans, (d) Euro-American police officers had, by far, the highest levels of social dominance orientation. Furthermore, all of the effects above held even when controlling for demographic factors such as gender, social class, age, education, and ethnic group. The theoretical implications of these findings are discussed.     

护士职业的人格特质研究

采用Ｙ－Ｇ性格测验问卷,对临床护士和在读护生共３９０人,进行了心理测评,展开了护士职业的人格特质研究。研究结果表明：优秀护士群体的性格类型和某些人格特质显著地优于一般护士群体;优秀护士与一般护士间所显现出显著差异的人格特质,对于护士角色人格的构成具有决定性影响;Ｙ－Ｇ性格测验的Ａ型性格类型评定对于护士职业的心理选拔显现特异性趋势;整个测评研究结果,基本支持＂护士个体人格特质与角色人格特质的匹配模式＂等理论假设．
