Normal high extraversion male subjects with high scores on a neuroticism scale were compared with similar subjects with low neuroticism scores, as to changes in the discrimination of paired flashes, brought about by activation‐induced heart rate increase. A threshold for fusion indicated slightly improved resolution for the low neuroticism group under increased heart rate, but a marked deterioration for the high neuroticism group. Two signal detection analyses indicated that the differential effects could not be attributed to response criteria and one analysis indicated group differences in sensitivity under activation.
