Abstract
As a test of Worthy’s (1974) hypothesis that sex and iride pigmentation are variables which act to determine level of behavioral reactivity, we measured the level of Type A behavior of 421 dark-eyed and 253 light-eyed college students. While our results failed to confirm predictions made from Worthy’s hypothesis, we found an unanticipated Sex x Iride Pigmentation interaction, i.e., dark-eyed females scored significantly lower on the Jenkins Activity Survey (our measure of Type A behavior) than dark-eyed males, but light-eyed females scored higher than light-eyed males. The implications of these data for Worthy’s hypothesis were considered.
