Measures of the Halstead-Reitan Neuropsychological Battery (HRNB) were factor analyzed with subtests of the Halstead Category Test (HCT) for 277 9-year-old learning disabled subjects. Eight factors with eigenvalues greater than one were rotated to a final solution that accounted for 67.9 percent of the total variance. HCT-Subtest 1 loaded…

This paper takes issue with the position that children's phoneme acquisition schedule is dictated primarily by auditory perceptual factors and suggests the alternative position that ease of production accounts for age of acquisition. It is felt that perceptual theory cannot adequately explain phonological development, e.g. three-year-olds produce…

The feasibility of completely automating the Minnesota Multiphasic Personality Inventory (MMPI) was tested, and item response latencies were compared with other MMPI item characteristics. A total of 26 scales were successfully scored automatically for 165 subjects. The program also typed a Mayo Clinic interpretive report on a computer terminal,…

A simple, rigorous, small-sample statistical technique is described for testing the hypothesis that two sets of measurements differ only because of errors of measurement and because of differing origins and units of measurement. (Author)

This research provides an initial evaluation of an actuarial diagnostic testing program that is being conducted by the Psychometric Laboratory at the University of Texas Medical Branch, Galveston, Texas. It was hoped that an actuarial program for psychiatric diagnosis would create greater efficiency, lower cost, and superior validity with respect…

A pair of related experiments examined the psychometric properties on the Threat Index (TI), a theoretically based scale for the assessment of threat of death. The high reliability of the TI suggested its functioning as an index of stable conceptual orientation toward death. (Author)

The present study was undertaken with two related goals: (a) to examine the relationships between the WRAT and CAT, and (b) to examine the relationships which may exist between these academic achievement tests -nd a standard intelligence battery such as the Wechsler Scale. (Author)

This study investigated the reliability and validity of the Philosophical Belief Inventory (PBI). With the exception of the relationship between idealism and pragmatism and realism and existentialism, the PBI scales appear to be assessing independent facets of belief. (Author)

Educational and psychological testing textbooks typically warn of the inappropriateness of performing arithmetic operations and statistical analysis on percentiles instead of raw scores. This seems inconsistent with the well-established finding that transforming scores to ranks and using nonparametric methods often improves the validity and power…

This paper provides a description of an online Rorschach interpretation algorithm for the Exner comprehensive system, as well as a study conducted to evaluate the validity of the online interpretive algorithm. The user, systems, and equipment specifications for the algorithm are explained, and the potential advantages of its use to enhance…

An introductory textbook on psychological tests and measurements is presented in paper back booklet form. The style is informal and humorous, and the book is intended to appeal to the contemporary student. Ten chapters constitute the text: (1) On Measurement and Existence; (2) A Brief, Imprecise History of Psychological Testing; (3) The Creation…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report describes the processes used for deciding what should be measured, when, and how. Work of the SMSG Panel on Tests for collecting tests items, conceptualizing scales, pilot testing, and analyzing pilot test data is reviewed. The…

Paper is concerned with the hypothesis that two variables have a perfect disattenuated correlation, hence measure the same trait except for errors of measurement. (Author/RK)
