    Heart rate and forearm blood flow responses were measured during experimental tasks requiring sensory intake, sensory rejection, and a mixture of the 2 behaviors. Subjects were 29 college students who had been categorized using Rotter's locus of control scale. Significant increases in both cardiovascular indices were seen in all 3 tasks; the responses were smaller, however, during sensory intake. Internals showed a differential response of forearm blood flow to sensory intake, in the direction of less of an increase in forearm blood flow. In contrast, externals showed a similar vasodilatation across all tasks. The findings indicate that some of the variability in cardiovascular response to sensory processing may be explained by individual differences in personality characteristics related to subjects' preferred level of involvement in differing sensory processing behaviors.
