Inhibition of pupillary orienting reflex by novelty in conjunction with recognition memory

Abstract

When recognition memory was well formed, stimulus novelty not only failed to elicit the orienting reflex in the form of pupillary dilation, but elicited pupillary constriction instead, demonstrating the relation of negative induction in the original sense of Pavlov’s theory relating the mechanisms of the pupillary orienting reflex to recognition memory. © 1974, The Psychonomic Society, Inc..
