Abstract
Effects of 2 methods of discrimination reversal (DR) upon previously established learning set (LS) were compared with a LS control in 12 squirrel monkeys, Saimiri sciureus. 1 group received 300, 3-trial DR problems. They remained at chance in this training and exhibited significant, but short-lived, loss in Trial 2-performance upon return to conventional 6-trial LS problems. A 2nd group received criterional DR training for 900 trials. Upon return to conventional LS problems they performed as well as the 3rd group which has received 150, 6-trial LS problems. Results were interpreted to mean that the 3-trial DR condition tended to extinguish the strategy of win-stay, lose-shift which is common to DR and LS tasks.Keywords
