先前知识对初中学生学习家族相似性类别的影响研究

采用特征—主题的类别学习范式,考察了先前知识对初中学生学习具有家族相似性结构人工类别的影响。结果表明:基于先前知识的主题关系对初中学生的类别学习有显著促进;初中学生在基于已有知识的类别学习中更多地获得了知识关联特征的信息,同时也能对机械特征保持敏感。     

Differential brain responses when applying criterion attribute versus family resemblance rule learning

Subsystems of category learning have been identified on the basis of general domains of content (e.g., tools, faces). The present study examined categories from the standpoint of internal structure and determined brain topography associated with expressing two fundamentally different category rule structures (criterion attribute, CA, and family resemblance, FR). CA category learning involves processing stimuli by isolated features and classifying by properties held by all members. FR learning involves processing stimuli by integral wholes and classifying on overall similarity among members without sharing identical features. fMRI BOLD response to CA and FR categorization was measured with pseudowords as stimuli. Category knowledge for both tasks was mastered prior to brain imaging. Areas of activation emerged unique to the structure of each category and followed from the nature of the rule abstraction procedure. CA categorization was implemented by strong target monitoring and expectation (medial parietal), rule maintenance in working memory, feature selection processes (inferior frontal), and a sensitivity to high frequency components of the stimulus such as isolated features (anterior temporal). FR categorization, consistent with its multi-featural nature, involved word-level processing (left extrastriate) that evoked articulatory rehearsal (medial cerebellar). The data suggest category structure is an important determinant of brain response during categorization. For instance, anterior temporal structures may help attune visual processing systems to high frequency components to support the learning of criterial, highly predictive rules.     

父子(女)间面孔相似性的进化适应机制及其影响

由于受精和孕育过程发生在母亲体内, 人类受孕具有一定的隐蔽性, 同时人类早期社会存在着通奸行为, 因而, 父亲面临着父亲身份不确定性的风险。为了应对这种风险, 人类男性在生活中往往会寻求一些能表征父亲身份的线索, 其中亲子间面孔相似性被证明是辨别个体间是否存在基因关联(或血缘关系)的有效线索之一。morph软件合成、第三方评定以及当事人的主观评定是研究亲子间面孔相似性的三种基本范式。以往的研究表明当父子(女)间面孔相似性越高时, 父亲对子女的亲子投资水平越高, 父亲感知到的焦虑水平越低, 父亲的身体也越健康, 与此同时, 当父子(女)间面孔相似性越高时, 父亲对女儿会表现出更高的性厌恶水平。未来的研究可以进一步关注文化因素在该效应中的调节作用, 探寻新的研究范式以提高研究的内部效度和外部效度, 以及探讨影响亲子间面孔相似性感知的因素。     

父亲严厉教养与父亲及儿童心理行为特点的关系：父亲与儿童类似性判断的调节作用

本研究分别调查了338名中国父母的严厉教养、抑郁情感与婚姻满意度及其独生子女的情感失调与攻击行为情况。研究结果显示父亲对儿童与自己的类似性判断减弱了父亲严厉教养与儿童的情感失调和攻击行为间的联系,但加强了父亲的严厉教养与抑郁和婚姻不满意度间的关系。这些发现支持了父母教养的进化观点,降低父亲的生殖疑虑可能具有进化适应性,父亲与儿童的类似性判断会提高父亲对儿童的投资     

Is overall similarity classification less effortful than single-dimension classification?

It is sometimes argued that the implementation of an overall similarity classification is less effortful than the implementation of a single-dimension classification. In the current article, we argue that the evidence securely in support of this view is limited, and report additional evidence in support of the opposite proposition—overall similarity classification is more effortful than single-dimension classification. Using a match-to-standards procedure, Experiments 1A, 1B and 2 demonstrate that concurrent load reduces the prevalence of overall similarity classification, and that this effect is robust to changes in the concurrent load task employed, the level of time pressure experienced, and the short-term memory requirements of the classification task. Experiment 3 demonstrates that participants who produced overall similarity classifications from the outset have larger working memory capacities than those who produced single-dimension classifications initially, and Experiment 4 demonstrates that instructions to respond meticulously increase the prevalence of overall similarity classification.     

Beyond Rigidity: The Unfinished Semantic Agenda of Naming and Necessity

To articulate their understanding of Hume’s discussion of ‘distinctions of reason’, commentators have often taken what I refer to as a ‘respect-first view’ on resemblance, in which they categorize resemblance as based on resembling respects. Holding this view, Donald Baxter argues that Hume’s view on the distinctions of reason leads to a contradiction. As an alternative, I offer ‘the resemblance-first view’, which is not dependent on resembling respects. I argue that this view is textually supported, and that it rescues Hume from the proposed contradiction.     

Body elimination attitude family resemblance in Kuwait

The purpose of the present study was to determine the family resemblance of attitude toward body elimination in Kuwaiti participants. This study was conceptualized in the context of the theories of moral development, importance of cleanliness in the Muslim religion, cross-cultural differences in personal hygiene practices, previous research reporting an association between family attitudes and body elimination attitude, and health implications. The 24-item Likert-type format Body Elimination Attitude Scale-Revised was administered to 277 Kuwaiti high school students and 437 of their parents. Females scored higher, indicating greater disgust, than the males. Moreover, sons' body elimination attitude correlated more strongly with fathers' attitude (r = .85) than with that of the mothers (r = .64). Daughters' attitude was similarly associated with the fathers' (r = .89) and the mothers' attitude (r = .86). The high correlations were discussed within the context of Kuwait having a collectivistic culture with authoritarian parenting style. The higher adolescent correlations, and in particular the boys' correlation with fathers than with mothers, was explained in terms of the more dominant role of the Muslim father in the family. Public health and future research implications were suggested. A theoretical formulation was advanced in which "ideal" body elimination attitude is relative rather than absolute, and is a function of one's life circumstances, one's occupation, one's culture and subculture, and the society that one lives in.     

Narrow Structuralism: Paving a Middle Path Between Cummins and Millikan

Millikan [2000] has levelled a number of persuasive criticisms against Cummins's [1996] theory of mental representation. In this paper, I pave a middle path in the debate between Cummins [2000] and Millikan [2000] to answer two questions. (1) How are representations applied to targets? (2) How is the content of a representation determined? The result is a new theory of mental representation, which I call narrow structuralism.
