MacCoun, R. J., & Kerr, N. L. (1987). Suspicion in the psychological laboratory: Kelman's prophecy revisited. American Psychologist, 42, 199.

Describes the spontaneous occurrence, during an experimental session, of an epileptic seizure experienced by 1 S. Three of the remaining 5 Ss suspected the seizure was part of the experiment; implications are discussed in terms of H. C. Kelman's suggestion that the frequent use of deception in social psychological experimentation creates Ss who enter the laboratory expecting to be deceived and are unlikely to react to the experimental context in a natural way.
