Defines data base for Army Selection and Classification Project (Project A) as containing two major samples: concurrent validation sample and longitudinal validation sample. Describes data base resulting from concurrent sample, sampling procedure, distribution of sample sizes over jobs, total array of variables, and data collection procedures.…

Describes the Army's Project A effort to scale the relative utility of different levels of performance across entry-level jobs, or Military Occupational Specialties. Explains how combined procedure incorporating interval estimation and ratio estimation method was used to estimate utility of 5 different performance levels for each of 276 jobs.…

Examined extent to which personality disorders and associated symptom criteria were found among 117 cocaine- and opioid-dependent men in drug dependence treatment unit. Drug groups were distinguished by higher rates of antisocial and borderline symptomatology rather than by features associated with other personality disorders. Different…

Three-, four-, five-, and 24-year-olds were exposed to continuum of new objects: category boundaries became less fuzzy with age; verbal justifications of category decisions were idiosyncratic or uninterpretable in youngest children, but by five years children referred to specific visual features; and fuzzy categories became less sensitive with age…

Argues that words with different meanings normally appear in discriminably different contexts, and that the cue for learning to associate direct antonyms is not their substitutability but rather their frequent co-occurrence in the same sentence. (Author/VWL)

The problem of scaling ordinal categorical data observed over two or more sets of categories measuring a single characteristic is addressed. Scaling is obtained by solving a constrained entropy model. A Kullback-Leibler statistic is generated that operationalizes a measure for the strength of consistency among the sets of categories.

Patterns of memory dysfunction were determined in 50 middle school learning disabled readers (LD) through a hierarchical cluster analysis. Results were consistent with memory capacity theories of LD and provided external validation for classification of LD readers on psychometric measures according to patterns of memory performance. (Author/DB)

Eleven experiments involving over 200 undergraduate students investigated how categorization of examples influences feature prediction for new examples. Results suggest that category-based prediction generally relies on a single category rather than multiple categories when there is a clear target category. (SLD)

An experiment with 4-, 7-, and 18-year olds investigated classifications of multidimensional objects to test whether the valuing of identity as a classification criterion occurs early in development; the distribution of attention to multiple relations increases with development; and the role of separate, component relations in solving…

Two classes of graded response models, one based on the work of L. L. Thurstone and the other on the work of G. Rasch, are juxtaposed and shown to satisfy important but mutually incompatible criteria and to reflect different response processes. Implications of the choice between these models are discussed. (Author/SLD)

This article presents a straightforward classification system that is a necessary and sufficient condition for identification of the structural component of structural equation models of the block-recursive type with no more than two equations per block. Limitations of other identification techniques are discussed. (SLD)

New data from the Current Population Survey were used to reclassify occupations by level of education and training required. The following categories resulted: first professional degree; doctorate; master's; work experience plus bachelor's; associate's degree; postsecondary vocational training; work experience; and short-term, moderate, or…

An extended marginal homogeneity model is introduced for the analysis of square contingency tables with the same ordinal row and column classifications. The model hypothesizes that the ratio in each column of table delta will exhibit an exponential function of the column. (SLD)

Guidelines are presented for categorizing, documenting, and storing a historical videotape collection. Causes of videotape deterioration are discussed. (Contains three references.) (SLW)

Presents a three-class taxonomy of current approaches to the provision of performance support and suggests that this could form the basis for future developments for electronic performance support. Intrinsic, extrinsic, and external types of performance support are described, and tables outline characteristics of intrinsic and extrinsic…
