Male and female enlistees were compared on the basis of their performance on the Armed Services Vocational Aptitude Battery. Mean Aptitude Index scores were compared for male and female enlistees on the original testing and on retest. Males scored higher on mechanical and electronics, and females scored higher on administrative and general. Both…

A method of factor extraction specific to a binary matrix, illustrated here as a person-by-item response matrix, is presented. The extraction procedure, termed ERGO, differs from the more commonly implemented dimensionalizing techniques, factor analysis and multidimensional scaling, by taking into consideration item difficulty. Utilized in the…

Developmental differences in the Denver Developmental Screening Test items were demonstrated between samples of children from Okinawa (n=615) and Tokyo (n=1171), who were 16 days to 6 years old. Journal availability: see EC 112 661. (Author)

Sets of inventory scales were constructed from a common item pool, using variants of what are here called the Inductive, Deductive, and External strategies. Peer ratings for 21 traits served as criteria. Very little variation in validity was attributable to construction strategies. (Author/CTM)

Person changes can be of three kinds: developmental trends, swells, and tremors. Person unreliability in the tremor sense (momentary fluctuations) can be estimated from person characteristic curves. Average person reliability for groups can be compared from item characteristic curves. (Author)

Looks at teacher employment procedures to see what might be termed discriminatory. (Editor)

Just as the Grey Squirrel and the Little Owl were brought to England by well-intentioned enthusiasts so also are well meaning educational enthusiasts anxious to import attainment tests from America. In the former case the results were disastrous for ecology and this research stresses some of the lessons to be learned from the American experience…

In a series of experiments, it was found that asking questions about information in a prose sequence while it is being presented can affect the degree to which that prose material is stored as a unitized whole, and that this in turn will affect how well that prose is remembered. (Editor)

A model designed to account for major factors on personality questionnaires is proposed and evaluated using the Differential Personality Inventory. Two respondent processes are postulated: sensitivity to the underlying desirability of items, and threshold for responding desirably. (Author/JKS)

A properly chosen test model defines the kind of dependence of the observable behavior on underlying abilities of the persons tested in the form of a data-adequate theory. The limitations and potential of several test models are detailed; and they are critically compared as an aspect of empirical evaluation. (Author/MV)

Statements made in a previous article of this journal concerning the Rasch latent trait test model are questioned. Methods of estimation, necessary sample sizes, several formuli, and the general usefulness of the Rasch model are discussed. (JKS)

The verbal analogy item as a measure of intelligence is investigated. Using latent partition analysis, this study attempts to identify a semantic structure of relationships that individuals use to comprehend completed analogies. The implications for test construction and test validity are discussed. (Author/JKS)

The reading comprehension items for a revision of the Nelson Reading Skills Test were administered to several hundred fourth and sixth-grade pupils in order to determine the passage dependency of each item. The passage dependency index was used to locate weak items. (Author/JKS)

Factor analysis of an administration of the Raven Progressive Matrices Test to children in grades 1, 2, and 3 revealed three orthogonal factors interpreted as (1) concrete and abstract reasoning, (2) continuous and discrete pattern completion, and (3) pattern completion through disclosure. Results are discussed in several contexts. (RC)
