Heart rate and skin resistance responses from thirty-six participants (5 men and 31 women) were recorded to determine if significant differences exist among three different types of inducing anger including the present state of anger (Actual Anger), anger elicited through imagination (Imagined Anger), and anger elicited through recollection (Recollected Anger). An analysis of variance indicated significant differences for heart rate among the three methods, F(2,35) = 8.75, p = .0009, but not for skin resistance, F(2,35) = 1.298, p = .287. However, contrary to the hypotheses forwarded, both Imagined and Recollected Anger generated significantly higher heart rate responses than Actual Anger. Implications of these findings and a theoretical framework for interpretation are both presented.

Open-field behavior was observed in 10-min tests of 10 males of each of eight taxa of muroid rodents. Results parallel those of an earlier study of muroid rodents by Wilson, · Vacek , Lanier, and Dewsbury (1976). Considerable variation among species was found for measures of locomotion, boli deposited, and most other behavioral patterns recorded. As in the Wilson et a1. (1976) study, animals displayed a strong tendency to seek walls. Correlation coefficients between measures of locomotor-exploratory behavior and number of boli are presented for 20 taxa of muroid rodents; no support is found for a negative correlation between these measures for these taxa.
