Popis: The relatedness of behavior elicited by reward reduction (successive negative contrast procedure) and behaviors produced by three animal models of anxiety (open-field emergence, elevated plus-maze, and context-shock fear conditioning) was examined by correlational and factor analytic procedures. Factor analysis (oblique rotation) indicated substantial independence among the tests: Trials 1 and 2 of the plus-maze loaded on two different factors unaccompanied by any other test; open-field emergence and context-shock fear loaded on the same factor; and negative contrast loaded on a fourth factor. However, negative contrast proved to be a dynamic process, with factor loadings changing across a 4-day postshift period—moving from an independent loading on the 1st postshift day to being clustered with context-shock fear and open-field emergence on the 2nd and 3rd postshift days to being clustered with just context-shock fear on the last postshift day. These latter data support a multistage theory of successive negative contrast.
