This study obtained multiple measures of three factors (capacity, strategies, and metamemory) hypothesized to cause memory improvement with age among younger (ages 5 to 8) to older (ages 8 to 11) children. Results suggested that fit of the 3-factor model was statistically significantly better than a 1-factor, general memory model for both age…

Latent dimensions underlying individual differences in performance of information-processing tasks and dual task combinations, and the existence of a time-sharing (TS) ability were studied in 81 male college students. Supportive evidence for a general TS ability was not found. An identified TS factor specific to task combinations is discussed.…

Discusses the Attitude Functions Inventory (AFI), which assesses the extent to which a person's attitude fulfills each of four psychological functions. Reports findings of a study, involving 249 undergraduates, that tested the construct validity of the AFI. Suggests that the AFI provides conceptually meaningful measures of the functions of…

Variations in "foot-in-the-door" effect (gaining compliance in small requests to increase compliance with larger requests) examined for enhancing client motivation to change in counseling. Participants (N=56) assigned to one of four conditions in 2 x 2 factorial design based on presence or absence of request and motivation labeling.…

In a Delphi study of research needs in educational technology, 89 experts suggested 163 research needs. High-priority needs were identified by the Scree test--a method usually restricted to factor analysis. The usefulness of the technique for analysis of survey results suggests that it should be extended to other applications. (SLD)

The accuracy of Houle's typology in providing an accurate conceptual description of systematic structural forms of continuing professional education and business education instructors was tested via a survey of 98 (of 129) business educators. Results of rotation factor analysis added inquiry/reinforcement to Houle's 3 learning modes of…

The Performance Scale of the Wechsler Adult Intelligence Scale-Revised was administered to 185 hearing-impaired young adults. A gender difference was found only on the Digit Symbol subtest, where females outperformed males. The high degree of factorial similarity between males and females indicated that the underlying construct being measured does…

The importance of defining variables to be put into correlation tables for factor-analytic research into intelligence is discussed. Research on job analysis, task decomposition, performance-related intelligence changes, and cross-cultural differences could be incorporated into definition of variables. (TJH)

The internal correlation--a measure of dependency in a set of variables--is discussed and generalized. Applications of the internal correlation coefficient and its generalizations are given for several data-analytic situations. The internal correlation is illustrated and the concept is expanded to a series of additional indices. (TJH)

Use of internal correlation for statistical analysis--proposed by G. W. Joe and J. L. Mendoza (1989)--is discussed. Focus is on the "content" question (what this application can do with the information that statistics contain) and the "eloquence" question (the advantages of this means of encoding information over other means). (TJH)

Multivariate distributions are studied in which all bivariate regressions can be linearized by separate transformation of each of the variables. A two-stage procedure, first scaling the variables optimally and then fitting a simultaneous equations model, is studied in detail. (SLD)

Subjected Modified World Affairs Questionnaire (MWAQ) to comparable common factor analysis which identified five factors: civil defense, escalation, nuclear war outcome, probability/worry, and patriotic. Alpha coefficients and test-retest reliability were determined to be adequate for the first four subscales. Acceptable discriminant validity and…

Satisfactory results for interpersonally incomparable ordinal survey responses can be obtained by assuming that rankings are based upon a set of multivariate normal latent variables that satisfy factor or ideal point models of choice. Two statistical methods based upon those assumptions are described and illustrated via simulations. (TJH)

Observational ratings of 112 preschool student teachers on 9 teaching behaviors were factor analyzed to yield 4 underlying latent variables: facilitating, interpersonal, interactive, and flexible behaviors. The latent variables were positively correlated with each other. A path diagram illustrates the relationships among teaching behaviors and…

The parameters of full-information item factor models of varying dimensionality and mixed-measurement models of varying numbers of latent classes were estimated in 1,000 responses to a measure of Positive Interpersonal Engagement. The most appropriate representation of the data and deciding between mixed-measurement and dimensional representations…
