Attempted to reconcile the apparently discrepant findings of R. A. Champion's and R. J. Bandler, G. R. Madaras, and D. J. Bem's (see record 1968-13090-001) studies of response to aversive stimuli. It was hypothesized that the discrepancy was in part a function of the choice provided by the Bandler, et al. instructions. 40 undergraduates were given 10 escape and 10 no-escape trials from aversive white noise. 1/2 of the Ss were given instructions which gave them the choice of escape or no escape, while the other 1/2 were given no such choice. Results support both studies. The use of choice instructions appears to be equivalent to giving the S a sense of control over the threatening stimulus.
