Intellectual, academic, and neuropsychological measures were used to derive three subgroups. Personality and behavioral data were used to identify four dimensions, which are discussed in terms of…

More than one correlation coefficient can be computed between two variables when the data can be organized into subsets determined by one of more grouping factors. Implications of this fact are discussed when the variables are items and the correlations are being computed for purposes of scale development. (Author/

Critical review of previous techniques for the measurement of an individual's self-concept (SC) is a necessary prelude to the development of more adequate methodologies. This paper focuses on recent methodological innovations in the study of the self, namely, those derived from cognitive social psychology. A view of the self as a cognitive…

Research explored methods of providing a coherent framework for the Instructional Systems Development (ISD) model which would promote better system evaluation, internal communications and student testing. Lists of critical tasks for two Air Force specialties were compiled and multidimensional scaling and hierarchical cluster analysis employed to…
