Abstract
Acquisition of a runway response by 71 albino rats in different segments of a straight alley was investigated as a function of percentage of reinforcement (50% or 100%), 3 drive levels, and shifts of reinforcement schedule. Preshift asymptotic analyses revealed a significant drive effect but no reinforcement schedule or Drive X Reinforcement interaction effect. Postshift trials (101-120) within group comparisons indicated that high- and medium-drive, continuously reinforced Ss shifted to partial increased speed of responding on 2 response measures but under low drive no change on any measure occurred. No change occurred for high- and medium-drive, partially reinforced Ss shifted to continuous reinforcement, but for low-drive Ss an increase in running speed occurred. Results are discussed in terms of Spence and Amsel''s recent theoretical statements.[long dash]Author.Keywords
