Summation,Variety, and Indeterminate Value

In this paper, I consider two sorts of objections to summative theories of value. The first objection concerns “indeterminate” value. The second concerns the importance of variety. I argue that both objections pose serious problems for the summative approach. I also argue that if we accept certain plausible views about the value of variety, we should reject certain forms of argument concerning what sorts of states have intrinsic value.     

The inference of covert hypotheses by verbal reports in concept-learning research

A paradigm designed to examine the degree to which verbal reports represent the subject's learning was evaluated using a concept-acquisition task. Specifically, the degree to which hypotheses verbalized during the concept-acquisition procedure represent the covert hypotheses controlling category responding was examined. Subjects were required to make category responses, verbal reports, and sorts and re-sorts (blank-trial probes) of the stimuli at intervals in a reception paradigm. By comparing the sorts made during the acquisition procedure, the re-sorts after a 1-week delay, and the sorts made by subjects who had not participated in the acquisition procedure, it was determined that the verbal reports do not accurately represent the underlying hypothesis-testing process under all conditions. Verbal reports elicited at the beginning of the acquisition procedure and at criterion accurately represented the underlying hypotheses; those elicited at intervening points did not. The ambiguity of the verbal reports was a similar function of acquisition trials.     

Form characteristics of category-retrieval relationships in children and adults

Subjects from Grades 2, 4, 6, and college performed a sort-recall task with 24 noncategorized items, using two 12-item sorts, four 6-item sorts, or six 4-item sorts. Among the children, the effects of increasing unitization at study were uneven across the category size conditions used and did not resemble the linear patterns shown by adults. Second graders showed retrieval advantages only for the smallest categories used, whereas fourth and sixth graders benefited from the use of moderately sized sorting categories but failed to show additional improvements for smaller sorting categories. An examination of subjects' sorting explanations suggested that different category-retrieval patterns may reflect better and poorer item relations established in smaller and larger categories, respectively. Sort conditions affording the best recall at the different grade levels were those in which subjects established the greatest number of contextual and categorical (taxonomic) relations among sorted items.     

刺激材料的整体性知觉对类别建构的影响

采用标准－匹配的实验程序,操纵刺激材料的空间整合性和知觉的整体性水平,探讨逐个呈现刺激材料时影响被试类别建构策略的根本原因。报告了3个实验,结果证明：逐个呈现并不一定会导致被试倾向于家族相似性归类;刺激材料的空间整合性不一定会影响被试的类别建构策略,空间整合和空间分离都可能出现家族相似性和单维归类倾向;刺激材料的整体性知觉水平对类别建构影响明显：知觉为分离则倾向于家族相似性分类;知觉为整体则倾向于单维分类。被试在实验可能采用分析性策略,然而材料的整体性知觉影响了分析的侧重点,从而对类别建构产生了非常重要的影响     

Constraints on Constraints: Surveying the Epigenetic Landscape

It is now relatively commonplace to advocate the need for some sorts of constraints on learning and knowledge acquisition. The critical issues to cognitive science concern the sorts of constraints that are able to best model various phenomena of learning and development. Four types of constraints on learning are proposed to be used as an interpretative framework within which to: 1. Better understand the nature of current research: 2. Allow the exploration of alternative models of learning related phenomena, and 3. See more clearly needs for further research. Superficially similar learning phenomena can be modeled by very different configurations of underlying constraints with strong implications for the sorts of representational states that are involved. Each of the five papers in this issue (Brown, Gelman, Markman, Newport, and Spelke) is considered in terms of the configuration of constraints after which each author intends to model their phenomena and in terms of alternate configurations. The papers are construed as illustrating a diverse set of models of how constraints might guide learning, and while the evidence generally favors the configurations suggested by the authors, in each case alternative models are possible and motivate quite specific future research questions. More broadly, it is suggested that asking detailed questions about the sorts of Constraints types that could potentially model complex cases of natural knowledge acquisition helps motivate fundamental questions about learning and the nature of knowledge and that the five papers in this issue are superb examples of how adopting this kind of perspective has been fruitful research orientation.     

The concept of the person and the value of life

The concept of the person has come to be intimately connected with questions about the value of life. It is applied to those sorts of beings who have some special value or moral importance and where we need to prioritize the needs or claims of different sorts of individuals. "Person" is a concept designating individuals like us in some important respects, but possibly including individuals who are very unlike us in other respects. What are these respects and why are they important? This paper sets out to answer these questions and to develop a coherent and useful concept of the person.     

Self-Ideal Congruence Among Engineering Managers

62 engineering managers described their actual and ideal job selves using Q sorts. Self-ideal congruence scores (Z scores) from the Q sorts were correlated with personality test scores, measures of job performance, and other variables. A significant positive relationship was found between self-ideal congruence and management effectiveness. The concept of self-ideal congruence, utilized by client-centered counselors to measure progress of counseling, also has meaning in an industrial context with “normal” persons. Since managers with high self-ideal congruence received higher job performance ratings, the self-ideal congruence score can possibly be considered as an index of job adjustment or measure of self-in-job actualization.     

A quantitative estimate of schema abnormality in socially anxious and non-anxious individuals

Although cognitive theories of anxiety suggest that anxious individuals are characterized by abnormal threat-relevant schemas, few empirical studies have estimated the nature of these cognitive structures using quantitative methods that lend themselves to inferential statistical analysis. In the present study, socially anxious (n = 55) and non-anxious (n = 62) participants completed 3 Q-Sort tasks to assess their knowledge of events that commonly occur in social or evaluative scenarios. Participants either sorted events according to how commonly they personally believe the events occur (i.e. "self" condition), or to how commonly they estimate that most people believe they occur (i.e. "other" condition). Participants' individual Q-Sorts were correlated with mean sorts obtained from a normative sample to obtain an estimate of schema abnormality, with lower correlations representing greater levels of abnormality. Relative to non-anxious participants, socially anxious participants' sorts were less strongly associated with sorts of the normative sample, particularly in the "self" condition, although secondary analyses suggest that some significant results might be explained, in part, by depression and experience with the scenarios. These results provide empirical support for the theoretical notion that threat-relevant self-schemas of anxious individuals are characterized by some degree of abnormality.

TWO KINDS OF INTENTIONALITY IN LOCKE

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities.     

Intending and Causing

In much of the contemporary discussion of end of life cases, active killing is forbidden doctors, whereas the passive bringing about of death is, e.g., a rather common occurrence in our hospitals. In the former sorts of cases, doctors are held to be causes of death; in the latter sorts of cases, they are held not to be. If they did not cause a death, even though they did passively bring it about, we cannot use casual responsibility for a death in order to raise possible questions about moral responsibility for that death. I here look at part of this insistence that doctors are not a part cause of death and call it into question.
