The present study is an effort to define the structure of normative values or belief systems regarding the desirable. As well it explored the relations of normative values to the liberal-conservative attitude dimension. (Author/RK)

Major finding was that neuroticism is unrelated to overall academic attainment for the high school sample. Although no global relationship was found, some interesting relationships were shown to exist between specific neurotic subvariables and specific achievement tests. (Author)

In the present article it is argued that the Least Squares Simplex Data Matrix Solution does not deal adequately with difficulty factors inasmuch as the theoretical foundation is insufficient. (Author/CB)

Authors conclude that, in the world of real data sample correlation matrices, Guttman's stronger lower bound is not of practical use in determining the effective number of common factors. (Authors/CB)

The longitudinal factor analysis" model, which uniquely resolves factors from two occasions of data representing the same persons measured on the same test battery, is shown to be derivable by application of canonical correlation procedures to factor scores. (Author)

Several alternative solutions are offered to problem posed in AA 513 150. (MB)

The Science Support Scale is not an appropriate instrument for measuring attitudinal changes in high school biology students. Factor analysis indicates that student interpretation of the items does not correspond to the theoretical subtest structure of the scale. (AL)

Results supported the hypothesis that increasing numbers of coactors results in increasing impairment of motor performance. (Authors)

The revised ITPA promises to have continued wide application. It successfully measures general linguistic ability and intelligence, and to a limited extent it successfully measures aspects of cognitive ability. However, it fails to measure many of the cognitive domains that it was designed to measure. (Author)

Purpose of the investigation was to identify the factorial dimensions of 25 characteristics on a scale for rating research articles. (Authors)

Results were quite similar for each of the factor analytic procedures, an indication of a strong underlying structure of the WPPSI tests. Regardless of the factor analytic technique used, two factors appeared--one clearly verbal and the other clearly performance--at each of the three age levels. (Authors)

A behavior problem checklist was administered to the teachers of six to eight year old children. Eight factors were identified as Hyperactivity, Disciplinary Problems, Sluggishness, Paranoiac Tendencies, Social Withdrawal, Acting Out, Speech Problems; and Antisocial Tendencies. Three second order factors were identified as Neutroticism,…
