Commonalities and differences in similarity comparisons

Similarity is a central component of many cognitive processes. Current research suggests that similarity is well characterized as a comparison of structured representations. This process yields commonalities, differences related to the commonalities (alignable differences), and differences not related to the commonalities (nonalignable differences). In the first study, further evidence for this tripartite distinction is provided in a commonality and difference listing study involving pairs of pictures. This study indicates that alignable differences rather than nonalignable differences are central to the comparison process by virtue of their connection to the commonalities. The second study further demonstrates that alignable differences count more against the similarity of a pair than do nonalignable differences. We end by discussing implications of the distinction between alignable and nonalignable differences for other cognitive processes involving comparisons.     

Racial Categorization and Stereotype-Based Judgments About Homeless People1

The present study uses a social-cognitive paradigm to examine the association between racial categorization and stereotype-based judgments about homeless people. The study uses data from a national White subsample (N= 1,221) surveyed about attitudes toward homeless/homeless mentally ill people. It was hypothesized that individual differences in perceptions of the representativeness of Blacks in the homeless population, as measured by subjective estimates of the percentage of Blacks, would be associated with the enhancement of racially relevant negative stereotypes about homeless people. A secondary hypothesis was that perceptions of the representativeness of Blacks would be more strongly associated with the stereotype of homeless people as dangerous than with the view of them as lazy. The results support these hypotheses.     

Women's marital-familial statuses and work histories: Some conceptual considerations

Although vocational psychologists and sociologists have a long history of researching occupational choice, their theoretical postures have almost always been shaped in light of information on males, with little consideration for females. This article is an addition to others which attempt to correct this shortcoming in the literature. The article reviews the dominant conceptual schemes used to study occupational choice, considers potentially female-specific variables, and provides a typology for the analysis of women's marital-familial statuses and work modes.     

Spacing repetitions over 1 week

Does varying the spacing of repetitions over intervals as long as 1 week aftect recall? The answer from three experiments is yes. Subjects incidentally processed words repeated within a single list and words repeated in separate lists at list spacings of up to 1 week. Memory was tested by free recall shortly after the second presentations or after retention intervals of up to 1 week. Recall of the words repeated across separate lists conformed to a proportionality rule. When the retention interval is short relative to the spacing intervals, performance is inversely related to spacing. When the retention interval is a large proportion of the spacing intervals, performance is directly related to spacing. Does varying the spacing of repetitions within a single list affect recall after a retention interval of 2 weeks? The answer depends on the processing used while studying the words. Processing that generated interitem associations resulted in a within-list spacing effect even after a 2-week retention interval. Without the interitem associations, the effect was absent after a 1-day retention interval. Most of these findings were explained by examining the changing relationship between the retrieval context and the context stored during study.     

Incorporating inferences in narrative representations: A study of how and why

Four experiments examined the conceptual organization of narrative passages and the extent to which these representations were explanatory in a variety of experimental tasks. The conceptual representation of a passage consisted of a graph of labeled nodes and labeled, directed arcs which were adopted from the Conceptual Dependency Theory. These representations included both explicitly stated information and inferences which had been empirically extracted by a question-answering procedure. Symbolic procedures for answering how- and why-questions were also delineated. The conceptual representations and the symbolic procedures that operate on these representations together accounted for 91% of the answers generated from question-answering protocols in Experiment 1, and also the rated quality of specific answers to specific questions in Experiment 2. Experiments 3 and 4 supported the hypothesis that structural properties of the representations can predict recall of explicitly stated nodes and verification ratings of inference nodes. The results provide encouraging support for the proposed graphic representations and also for the use of question-answering protocols in uncovering prose inferences.     

Raising the IQ: The Ramey and Haskins study

The Ramey and Haskins intervention experiment succeeded in producing IQ gains at three years of age averaging about one standard deviation in young children who were selected for being at risk for subnormal intellectual development. The study is examined in terms of its consistency with other findings, the heritability of IQ, the g aspect of IQ, the simplex pattern of longitudinal interage mental test score correlations, mother-child IQ correlations, and criteria for establishing educationally and socially significant gains in intelligence defined as g rather than as a score on a particular test. Narrow transfer of training from cognitive intervention techniques to IQ test performance in early childhood, rather than enhancement of the g factor itself, is hypothesized as a cause of the typical fadeout of early IQ gains in later childhood.     

Resolving Ethical Dilemmas in Management: Experimental Investigations of Values, Accountability, and Choice

Hypotheses regarding the effects of personal values and accountability on the resolution of ethical dilemmas in management were formulated and tested experimentally with a sample of 135 M.B.A. students. Personal values were found to be related to how subjects chose to resolve an ethical dilemma presented to them; but, as expected, this relationship did not hold when subjects were made to feel accountable to another for their choices. Accountability, unexpectedly, however, did not have a main effect on choices. This lack of an effect tentatively was attributed to the inexplicitness of the accountability manipulations. In a second and third experiment, support for the importance of explicitness in accountability research was obtained. The theoretical and practical implications of the findings from all three experiments were discussed.     

Respect: Response to shame in health care

Shame is a not uncommon experience of patients in health care settings. Religious assessments often confuse shame with guilt, and therefore respond in ways that may not be appropriate. Illustrated by a case study, this article distinguishes shame from guilt and examines systemic considerations. Then shame is explored in relation to traditional, negotiating, and individualistic belief paradigms, looking at epistemology, causality, response to shame, healing models, and tasks. It concludes with a discussion of the idea of respect as foundational for responding to people experiencing shame in health care.
