Simultaneous approach and avoidance learning in the teleost marine fish Serranus Scriba Cuv

Abstract

The ability of the fish to discriminate between constant light (the conditional stimulus of food) and flickering light (the conditional stimulus of a painful electric shock) administered in random order during the same experimental sessions was investigated. Approaching the light for food and avoiding the shock by moving away from the light could be tought simultaneously, approach learning being faster.
