Eyewitness identification decisions are vulnerable to various influences on witnesses' decision criteria that contribute to false identifications of innocent suspects and failures to choose perpetrators. An alternative procedure using confidence estimates to assess the degree of match between novel and previously viewed faces was investigated.…

A reminding-based generalization view of category learning was studied in 4 experiments involving a total of 247 college students. Experiments demonstrated that categorization by reminding can affect what is learned about the category and later categorization performance. Implications of the results for category learning are discussed. (SLD)

The development of the ability to use taxonomic, phonemic and sense impression categories as dimensions of encoding was investigated using third and fifth graders and college students. (ED)

Two experiments were conducted to establish the psychological validity of the text type distinction. In the first, 20 college students sorted 12 texts on the basis of their similarities. The resultant sortings were subjected to a clustering analysis. Despite the fact that other bases for grouping texts existed--a number of pairs of semantically…

Two experiments were conducted with 124 undergraduate and graduate students to investigate the interaction between strategy use and accessibility to relevant knowledge. Variations in relevant knowledge accessibility significantly affected strategy use on the first memorization trial, and ease of use on the first trial affected maintenance of the…

Literature in mathematic problem-solving suggests that learners store information in memory which helps them solve stereotyped algebra word problems. Cluster analysis has been used as an exploratory tool to infer the types of problems which have common representations in memory. This study compares the results of a hierarchical cluster analysis of…

The ability of preverbal infants to abstract a prototypical representation of a category, when presented with examples of an artifically constructed category, was investigated. It was determined that infants could process visual information constructively and could take a more active role in category formation than previously believed. (Author/MH)

A study examined the effect of variation in category dominance on retrieval latencies (and errors) from semantic memory. Subjects, 66 students enrolled in an introductory psychology course, were required to perform 6 successive retrievals from each of 18 conceptual categories. The six retrievals consisted of two successive blocks of three from…

In a study of individual differences in long-term memory access, university undergraduates verified (1) whether an item was a member of a category; (2) whether two items belonged in the same category; and (3) whether two words had the same name. Reaction times from these tasks were correlated with verbal ability, as measured by performance on a…

The four sections of this paper provide an analysis of the structure of human memory. The first section, intended to provide a clear example of personal memory, examines a hypothetical episode in the life of an undergraduate student, and shows how one episode can give rise to three different forms of memory: personal, semantic, and rote…

Two studies involving 195 undergraduates investigated memory errors occurring when the context standard used in judging target behaviors differs from the category norm standard available when behaviors are recalled. Results support a "natural" tendency to use the current categorical meaning of a judgment to reconstruct the referent of…

Investigates the influence of logical skills (inclusion and seriation) on the degree and kind of semantic integration performed on remembered material among 47 third- and fourth-grade boys and girls and college students. (JMB)

A model of category effects found in reports of episodic memory is proposed. The model holds that stimuli are presented at a fine-grain level of detail and a category. Four experiments involving a total of 131 University of Chicago (Illinois) students and faculty are reported in support of the model. (SLD)

Investigated a prior classification of Wechsler Memory Scale-Revised (WMS-R) subtests into Verbal and Visual categories. Findings from 45 college students found that memory test performance correlated significantly with performance on subtests of Form II of Luria-Nebraska Neuropsychological Battery that measures substrates of particular memory…

The organizational factors in memory relevant to learning medical diagnosis terms are discussed in this paper. Two hypotheses are tested: that the type of list organization will affect total recall; and that the type of curriculum and year in school will affect the organization of recall. Ninety-six second and third year medical students from two…
