Partial reinforcement and resistance to extinction in honeybees

Abstract

Previous experiments have shown the partial reinforcement effect in honeybees under conditions which permit an interpretation in terms of sensory carryover. In the five experiments reported here, the effect was sought under conditions which would require an interpretation in terms of associative reinstatement. Since it is not feasible to train honeybees in widely spaced trials, several different interpolated-trials procedures were employed which had in common the feature that nonrewarded response to a stimulus never was followed by rewarded response to the same stimulus. Implications of the negative results for the interpretation of the overlearning-extinction effect and successive negative contrast in honeybees are considered. © 1986 Psychonomic Society, Inc.
