On the optimality of the simultaneous redundancy transformations

The objective of this paper is to introduce and motivate additional properties and interpretations for the redundancy variables. It is shown that these variables can be derived by application of certain invariance arguments and without reference to the index of redundancy. In addition, an optimality property for the variables is presented which is important whenever one restricts attention in a study to a subset of the redundancy variables. This optimality property pertains to the subset rather than to the individual variables.This paper is based in part on the author's doctoral dissertation, Department of Statistics, Princeton, University. Research was conducted under the supervision of Lawrence S. Mayer.     

A constructivist analysis of the Rotter I-E scale1

A conception of locus of control attribution was advanced as an alternative to the generalized expectancy view presented by Rotter. That alternative stems from regarding the individual as actively constructing a pattern of specific choice consequence relations out of his/her ongoing experience. An integration of structural and factor approaches was used to analyze the Rotter I-E scale. The structural analysis categorized items on four dimensions (focus, area, self-attribution and world attribution) and indicated that the I-E scale unevenly represents the domain it encompasses. Nevertheless, specification of that structural matrix helps to provide a more comprehensive framework for interpreting I-E response patterns of 216 high school juniors and seniors. For example, male responses cohered around asserting active control over tasks hut attributing control to external sources with regard both to personal issues and to more abstract systems-related issues. Females organized their senses of self-efficacy with a central theme being that of a passive agent stance, plus an expectation that circumstances would provide equality of opportunities to which they could respond. Thus the present approach has demonstrated its utility in interpreting I-E findings and its conceptual advantage for personality research on locus of control and on similiar attributional characteristics.
