Context-specific conditioning in the conditioned-emotional-response procedure.
In 3 experiments, rats were used to investigate the conditions that influence the transfer of a conditioned emotional response from 1 context to another. The subjects experienced training in 2 contexts on each day. In Experiment 1, subjects received a single conditioning trial with a different target stimulus in each of the 2 contexts. Conditioned responding was found to be more vigorous when the target was presented subsequently in the context in which conditioning had taken place than when it was presented in the other context. Experiments 2 and 3 confirmed these results and also showed that neither the unconditioned response evoked by the target stimulus nor the conditioned response acquired after multiple training trials showed evidence of context specificity. Possible reasons for the difference in outcome between single-trial and multitrial conditioning procedures are discussed.
