Representations In The Brain

The representation of objects and faces by neurons in the temporal lobe visualcortical areas of primates has the property that the neurons encode relativelyindependent information in their firing rates. This means that the number ofstimuli that can be encoded increases exponentially with the number of neuronsin an ensemble. Moreover, the information can be read by receiving neurons thatperform just a synaptically weighted sum of the firing rates being received. Someways in which these representations become grounded in the world are described.The issue of syntactic binding in representations, and of its value for a higher orderthought system, is discussed.     

音乐情感交流研究中的透镜模型

介绍了研究音乐情感交流的透镜模型和透镜模型等式及其在音乐教育中的应用。透镜模型旨在解释演奏者如何通过多种或然且部分过剩的线索表达情感,听者如何使用这些线索识别演奏者表达的情感。透镜模型等式（LME）将演奏者和听者线索利用的回归模型联系起来。以透镜模型为理论基础,LME为数学基础产生了用于改善音乐演奏中的情感交流的认知反馈法（CFB）,即在演奏者演奏结束之后,向演奏者反馈其线索利用与欣赏者的线索利用相比较的结果,以提高演奏者与听者线索利用的一致性     

实践智慧在二十一世纪(上)

Prudence是为了实现好的行为和政治的可持续性而适用于处理偶然性的那种智识。要将prudence复原为与晚近现代之狂妄自大不同的另一种选择,人们应该考虑到,它那些与众不同的特征是如何反映出人类行为的深刻困境的。这些特征通过用以界定实践智慧话语的历史、理论、实践、结构、品质和观众等方面而得以鉴别,它们在本杂志(《现代哲学》)中分成两部分来陈述。这第一部分强调了偶然性、多元性和实践性这几个条件,并且通过对其规范的、计虑的和施行的这些表达方式的阐述来界定实践智慧。明智(审慎)的行动者就是这样的人,他平衡着各种不可通约之善、洞悉着各种可能的行动方略,以及用一种适当及适时的方式与他人进行着互动协作。     

三国时期君臣关系中的道德生活

三国时期的君臣关系呈现出一种二重化的结构,以汉献帝为中心的君臣关系和三国中各自的君臣关系.这一时期君臣关系中的道德生活就是围绕上述两重结构而展开的.在以汉献帝为中心的君臣关系结构中,忠于汉室和汉献帝的思想、行为与怀有异心、欲取汉室而代之的思想行为同时并存,体现初尽臣道和不尽臣道的明显差异.在三国各自的君臣关系中,其道德生活呈现出从正常到不正常的变化规律.     

The Proofs Of The Grundgedanke In Wittgenstein's Tractatus

The Tractatus contains twodifferent proofs of the Grundgedanke, or thenonreferentiality of logical constants. In thispaper, I explicate the first proof in TLP 5.4s andreconstruct the less explicitly stated second proof. My explication of the first proof shows it to beelegant but based on an invalid inference. In myreconstruction of the second proof, the main argumentis that the sign of a logical constant does not denotebecause it possesses the punctuation-mark-nature. Andit possesses the punctuation-mark-nature because,given the analyticity thesis in TLP 5, one canestablish for everyday language an adequate symbolismwith N as the sole fundamental operation such that itssign is a bar indicating merely the order and scope ofits application.     

The Heuristic Power Of Oppositionality In An Incidental-Memory Task: In Support Of The Construing Process

From a personal construct view, construing is a top-down process in which wider meanings predicate narrower, targeted meanings. Predicate contexts are invariably oppositional, as Kelly's (1955) theory reflects. Two memory experiments using college subjects are presented. Subjects were asked to focus on a series of 30 target words to determine if they were similar in meaning to a predicating word (e.g., friendly). Ten of these target words were relevant (e.g., congenial), 10 were opposite (e.g., impolite), and 10 were irrelevant (e.g., abstract) in meaning to the predicating word. Subjects were then (unexpectedly) asked to recall as many words as possible. In line with experimental instructions, the majority of these recalled words were relevant to the predicating word. However, as predicted, in both experiments significantly more opposite than irrelevant words were recalled (p < .001). The results are in support of a personal construct view of human cognition.     

Contents Just Are In The Head

The purpose of the paper is to show that semanticexternalism – the thesis that contents are notdetermined by ``individualistic' features of mentalstates – is mistaken. Externalist thinking, it isargued, rests on two mistaken assumptions: theassumption that if there is an externalist wayof describing a situation the situation exemplifiesexternalism, and the assumption that cases in which adifference in the environment of an intentional stateentails a difference in the state's intentional objectare cases in which environmental factors determine thestate's content. Exposing these mistakes leads to seethat the conditions that are required for thetruth of externalism are inconsistent.     

Response-independent Events In The Behavior Stream

The metaphor of the behavior stream provides a framework for studying the effects of response-independent food presentations intruded into an environment in which operant responding of pigeons was maintained by variable-interval schedules. In the first two experiments, response rates were reduced when response-independent food was intruded during the variable-interval schedule according to a concomitantly present fixed-time schedule. These reductions were not always an orderly function of the percentage of response-dependent food. Negatively accelerated patterns of key pecking across the fixed-time period occurred in Experiment 1 under the concomitant fixed-time variable-interval schedules. In Experiment 2, positively and negatively accelerated and linear response patterns occurred even though the schedules were similar to those used in Experiment 1. The variable findings in the first two experiments led to three subsequent experiments that were designed to further illuminate the controlling variables of the effects of intruded response-independent events. When the fixed and variable schedules were correlated with distinct operanda by employing a concurrent fixed-interval variable-interval schedule (Experiment 3) or with distinct discriminative stimuli (Experiments 4 and 5), negatively accelerated response patterns were obtained. Even in these latter cases, however, the response patterns were a joint function of the physical separation of the two schedules and the ratio of fixed-time or fixed-interval to variable-interval schedule food presentations. The results of the five experiments are discussed in terms of the contributions of both reinforcement variables and discriminative stimuli in determining the effects of intruding response-independent food into a stream of operant behavior.     

The Study Of Effects In Manova

A particular strategy for investigating effects resulting from a MANOVA is proposed. The strategy involves multiple two-group multivariate analyses. The two groups result from considering multivariate pairwise group contrasts or multivariate complex group contrasts. Assuming a given two-group analysis yields real effects, the resultant single linear discriminant function (LDF) may be studied. A rationale based on a transformation of LDF weights, due to V. Y. Urbakh, is recommended for assessing variable relative contribution. The analysis strategy is described in detail and illustrated with real data sets.     

The Look In Sartre and Rich

The relevance of Sartre's theory of “the look” for feminist philosophy is evaluated through juxtaposition of his analysis with images of women's oppression in Rich's early poetry. A theory of liberation that recognizes the existential dimensions of women's situations is presented. Following traces of feminist vision in Rich's recent work challenges the category of “woman” which lies at the root of the sexism.     

条件性味觉厌恶分化后臂旁核c-fos表达的变

以口内注入糖精或蔗糖溶液为条件刺激,腹腔内注射LiCl为非条件刺激,在大鼠形成条件性味觉厌恶后进行分化训练,观察味质和嗜好性对臂旁核各亚核c-fos表达的影响及其交互作用。结果表明：味质和嗜好性对背侧外侧亚核(dls)和腹侧外侧亚核(vls)的c-fos表达无影响;在内侧外侧亚核(ils)和外部内侧亚核(ems),蔗糖诱导的c-fos表达高于糖精,但在外部外侧亚核(els),糖精诱导的表达高于蔗糖;嗜好性刺激引起ils、中央外侧亚核(cls)和cms内c-fos高表达,厌恶性刺激引起ems和els内的高表达。在ils和cms嗜好性与味质的影响各自独立,在els和ems内嗜好性与味质的影响存在交互作用。提示PBN内存在味质辨别和报酬评价的代表区,两种代表区有交迭,ems和els对味质信息和报酬信息的整合有重要作用     

Association Between The Search For Meaning In Life And Well-Being In Chinese Adolescents

Theories suggest that having a meaningful life has beneficial effects on adolescent well-being. Encouraging adolescents to search for meaning in their lives is therefore well advised. However, whether and how the search for meaning in life (SMIL) is related to adolescent well-being is unclear. Thus, this study tested the following two hypotheses, based on a sample of 1539 Chinese adolescents in the tenth grade (M_age = 15.8 years): 1) the SMIL promotes adolescent well-being (“SMIL-as-promotor”), and 2) social connectedness mediates the link between the SMIL and adolescent well-being (“connectedness-as-mediator”). Multiple regression analyses revealed that SMIL was positively associated with life satisfaction, self-esteem and positive affect, and negatively associated with negative affect in the adolescents who exhibited low levels of presence of meaning; thus supporting the SMIL-as-promotor hypothesis. Mediation analyses revealed that SMIL was related to social connectedness (i.e., parent-child communication and peer relationship), which, in turn, was linked to the presence of meaning and hedonic well-being (i.e., life satisfaction, self-esteem, positive affect, and negative affect). These findings support the connectedness-as-mediator hypothesis. The implications of these findings for youth prevention programs and intervention services are discussed.

     

The Illegal Way In and The Moral Way Out

At the heart of the current debate about immigration we find a conflict of convictions. Many people seem to believe that a country has a right to decide who to let in and who to keep out, but quite often they appear equally committed to the view that it is morally wrong to expel someone from within the borders of their country if that would seriously jeopardise the person in question. While the first conviction leads to stricter border controls in an attempt to prevent would-be immigrants from entering the country illegally, the latter conviction ensures that aliens with a legitimate claim on protection will not be removed forcibly. It is not strange, therefore, that the task of pinning down a morally sound immigration policy is such an elusive enterprise.
In this paper I take it for granted that no electorate would be prepared to accept the kind of policy they ought to, and that we in consequence will continue to let in as few immigrants as is currently the case. Given this constraint I argue against two common assumptions concerning a viable immigration policy. First, granted that certain conditions are satisfied, professional smugglers should not face legal sanctions for bringing asylum seekers to a potential host country. Second, countries that limit immigration should not treat people seeking family reunion preferentially or on a par with other immigrants, but rather act so as to maximise the number of refugees allowed to enter.     

元认知结构在教学背景中的理解

近20年来,元认知(metacognition)成为心理学研究的热点之一,人们提出了一系列的元认知理论,试图对人的认知与学习过程作出更为深入的探讨和解释。在许多认知活动中元认知都起着重要作用,这些活动包括口头信息交流、口语理解、阅读理解、写作、语言习得、知觉、注意、记忆、问题解决、社会认知和各种形式的自我控制、自我指导等等。本文主要谈:在教学背景中,对元认知的含义及其结构的理解。
