Six rats were trained to perform on a VI 15 second food reinforced schedule following 30 consecutive days of daily treatment with 160.0 mg./kg. RNA. Another group of six was similarly treated with saline. There was no difference in the mean number of sessions it took either group to achieve defined asymptotic behavior, but the RNA pretreated animals displayed a two-fold increase in response rate, during both acquisition and extinction. These findings are discussed in terms of “learning… CONTINUE READING
