Abstract
In the present study, six groups of 10 albino rats each were given differential conditioning training in parallel alleys differing only in brightness. The results showed a positive S+ contrast effect when 20-sec delay of reinforcement or lowered drive (12-h deprivation) were used to lower responding, but a negative S+ contrast effect when subjects received both immediate reinforcement and 23-h deprivation. No present theory can adequately explain both effects.
