Data collected in a study of hospital staff attitudes to drug addicts and other types of patients are used to illustrate the problem of concept-scale interaction in semantic differential research. (Authors)

A general theoretical rationale is outlined for identifying different kinds of traits, states and function fluctuations of intelligence, providing a basis for developing a set of mathematical procedures which would allow for some separation of traits and states, both seen as patterns of distinct but covarying processes.

The Little Jiffy" consists of principal components analysis and varimax rotation of all components with eigenvalues greater than one. (DG)

Results indicate that factor types in Q-technique studies will be considerably more influenced by ordering preferences than they will be by distribution preferences. (AG)

A computer program designed to compare factors from similar concept matrices (person by scale) obtained at different times is presented. (PR)

The psychometric properties of a revised version of Holland's Vocational Preference Inventory were assessed using federal government employees. Factor analyses, interscale correlations, measures of internal consistency, and criterion group profiles are presented. Evidence was supportive of the validity of the revised form. (Author/BW)

The Test of Logical Thinking was designed to measure five modes of formal reasoning: controlling variables, proportional reasoning, combinatorial reasoning, probabilistic reasoning, and correlational reasoning. Analysis of data from students, grades 6-16 indicated high test reliability and confirmed that the test measures one underlying dimension,…

The structure of the Group Embedded-Figures Test was examined. Data from 173 females and 93 males were subjected to Johnson's complete-linkage cluster analysis and principal components analysis. The results showed the importance of simple form type, especially Form E, the cube, and of item position. (Author/RD)

The factorial validity of the Teacher Occupational Stress Factor Questionnaire was determined. Results provided partial support for the construct validity of the instrument. Item rearrangement resulted in changing the composition of three of the five factors; this was thought to provide data for investigating teacher stress. (Author/GK)

The effects of under and overrotation on common factor loading stability under three levels of common variance and three levels or error are examined. Four representative factor matrices were selected. Results suggested that matrices which account for large amounts of common variance tend to have stable factor loadings. (Author/RL)

Reliability and factorial validity of the Attitudes Toward Mainstreaming Scale was supported in a cross-validation study with teachers. Three factors emerged: learning capability, general mainstreaming, and traditional limiting disabilities. Factor intercorrelations varied from .42 to .55; correlations between total scores and individual factors…

The generality of ability factor structure in adulthood and old age was investigated. Data were analyzed for 198 young individuals (15-32 years), 156 younger old individuals (53-68 years), and 156 older old individuals (69-91). Variables were nine tests marking three ability factors. (Author/CTM)

This paper presents a method which can be used to obtain evidence that the concepts rated on semantic differential scales are appropriate for given study. An analysis of six semantic differential concepts, as perceived by 168 graduate education students, is presented; variations of the method are discussed. (Author/GSK)

The conceptualization of teacher role has led to the six-factor Role Dimension Profile Scale. When responses to the scale used with a Likert data collection format are analyzed, the resulting single dimension is interpreted as the teacher's "professional horizon." Implications of these results are discussed. (Author/GSK)
