Theories provide valuable guidance for research and practice. They provide a framework for generating testable hypotheses and integrating empirical evidence and, over time, a road map for the design and implementation of intervention strategies. With repeated use, a theory or set of theories can become the dominant lens through which investigators…

This research was designed to demonstrate that one function of aggression is the restoration of power. Also investigates the effects of timing of aggression on the intensity of aggression. (Editor/RK)

There is increasing debate over the unidimensionality of the construct "drive" in theories of behavior.

Both of these, however, were eclipsed by a positive-positive interaction as a determinant of interpersonal attraction. (MJP)

Based on the assumption that inferential statistics can make the operant conditioner more sensitive to possible significant relationships, regressions models were developed to test the statistical significance between slopes and Y intercepts of the experimental and control group subjects. These results were then compared to the traditional operant…
