The Effect Of Shifts In Reward Magnitude And Changes Of Schedule Of Reinforcement On Resistance To Extinction, Richard James Boylan
All Master's Theses
The problem concerned the resistance to extinction of an alley running response as a function of various combinations of reward sizes (l or 10 pellets) and schedules of reinforcement (50 or 100%). Three experimental phases were used (acquisition, shift of reward, and extinction). Three measures were taken in the alley (start, alley, and goal speed). Animals trained under partial reinforcement (PRF) showed no significant differences in acquisition running speed over animals trained on continuous reinforcement (CRF). Depression effects (decreases in running speed) were observed for both CRF and PRF trained animals during the shift phase. Overall tests between PRF and …
