Aversive CSs suppress lever pressing for food but not the eating of free food

Forty rats received CER acquisition, half “on the baseline” (response lever present), half “off the baseline.” During initial CER extinction, Ss received: (a) normal CER extinction (lever available), (b) free food during CSs only (no lever), (c) free food during non-CSs only (no lever), or (d) free food during both CS and non-CS periods (no lever). While normal extinction Ss were highly suppressed in the presence of the CS, all free food groups readily ate but did not differ in eating latencies. On subsequent CER extinction trials on the baseline, those Ss which received free food during the CSs were no less suppressed than other Ss. These data offer no support for Estes' (1969) reciprocal inhibition explanation of CER and punishment, nor do they support a fear interpretation of CER.     

Information extraction during visual search: A developmental progression

Five developmental experiments examine the role of context in visual search. Experiments I and II presented either lists or paragraphs that were either in meaningful context or scrambled. Results showed a significant interaction of these variables. Experiment II examined within-item context or predictability and replicated and extended the work of Brand (1971) and Ingling (1972). Experiments IV and V examined search through lists of various widths; results showed a significant interaction of Grade × Position × Width reflecting the different perceptual spans of children and adults. Although these were search tasks, appropriate comparisons between list and paragraph performance were made allowing interpretations of the results to be supportive of a model of reading in which meaningfulness, predictability, and peripheral vision play critical roles.     

Three computational versions of proportion correct for use in forced-choice experiments

Three commonly used measures of performance in forced-choice experiments, all called proportion correct, are compared as response bias, bias in the stimulus outcomes, and level of performance are varied. No position is taken on the question of which is the computational version of choice, but some of the characteristics of the various versions are examined.     

The relationship of factorially validated measures of anger-proneness and irrational beliefs

Cognitive-behavioral formulations have proposed that anger disorders are mediated by irrational beliefs. The modification of irrational beliefs has been followed by reduction in anger-proneness. Determination of a causal relationship, however, requires at least a correlation between irrational beliefs and proneness to anger arousal. Subjects completed a validated measure of self-reported anger-proneness and of irrational beliefs. Multiple regression analyses showed significant positive relationships between all dimensions of anger proneness and several irrational beliefs. Implications for the cognitive-behavior modification of anger are discussed.This work was originally presented at the Annual Convention of the Midwest Psychological Association, Minneapolis, May 1982.     

Perceptual differences in gender ideals among heterosexual and homosexual males and females

The relationship between sexual oreintation (heterosexuality vs. homosexuality) and perceptions of self, ideal male, and ideal female was investigated. Using the Androgyny scale of the Bex Sex Role Inventory [S. L. Bem, “The Measurement of Psychological Androgyny,” Journal of Consulting and Clinical Psychology, 1974, 42(2), 155–162] data were analyzed for 144 male and female subjects. The results indicated that homosexual, compared to heterosexual, subjects were least likely to stereotype their three perceptions, yet showed a significant difference between their perceived self and their same-sex ideals. Moreover, homosexual females were the only group to show a significant difference between their perceptions of the ideal male and ideal female, and to categorize all their perceptions within an androgynous range. Furthermore, they were least likely to utilize traditional sex roles in organizing their perceptions. Finally, the homosexual males, although not as extreme as heterosexual males, still maintain a slight tendency to stereotype their perception of an ideal male.
