Methamphetamine Hydrochloride and Reactions to Aversive Shock and Reward Decrements
A total of 136 rats were employed in three experiments which assessed the effect of methamphetamine hydrochloride on passive avoidance behavior, on the energizing properties of non-reward in the double runway, and on the decrement in runway performance, which follows a drop in reward value. The drug increased passive avoidance behavior, did not alter the effects of non-reward in the double runway, and reduced the performance decline occasioned by…
Effect of Deprivation Level and Overtraining on Differential Conditioning and Reversal
60 rats received 60 or 204 differential instrumental conditioning trials under 3-, 19- or 43-hr. water deprivation, followed by 60 reversal trials. In early acquisition speeds to both S+ and S—were greater with increased deprivation, but the subsequent onset of differentiation was most rapid in groups run at 43-hr. deprivation, this produced by their slower running to S—. Reversal performance was but little affected by deprivation, not was there …
Extinction and Reacquisition Performance as a Function of Sucrose-Solution Rewards and Numbers of Acquisition Trials
Hungry rats ( n = 76) received straight runway acquisition training at 1 of 3 sucrose reinforcement magnitudes (20 licks, 5% solution; 20 licks, 50% solution; or 100 licks, 50% solution) for 1 of 3 numbers of training trials (20, 40, or 100). This was followed by 40 extinction trials, then 16 reacquisition trials at either the highest or the lowest reward magnitude. Both acquisition and extinction performance were increased by larger values of th…

Amobarbital Sodium and the Effects of Reward and Nonreward in the Amsel Double Runway
Rats received 60 trials (Condition I) with 6 pellets reward at the second goal of a double runway and either 6 ( n = 12) or 0 ( n = 12) at the first goal, followed by, for all Ss, 24 trials (Condition II) with 0 reward at the first goal, then 36 trials (Condition III) with 50% reward at the first goal. Half of each reward group received amobarbital sodium (20 mg/kg, IP) and half saline prior to the 6 daily trials. Neither excitatory nor inhibitor…
T-Maze Performance as a Function of Consummatory Activity
Wike and Barrientos ( 1957 ) examined the possibility that selective learning might be positively related to the duration of consummatory activity. Thirsty rats received T-maze training in which both responses were followed by a 5-ml. water reward, on one side through a 0.25-in. diameter tube and on the other through a 0.19-in, tube. The smaller tube required the longer duration consummatory response, and because Ss learned to approach the smalle…
Psychology of the Scientist
Three groups of undergraduate volunteers were given differential expectancies about S's behavior prior to their observations of planaria undergoing conditioning. Group HE ( n = 5) received a high response expectancy, Group LE ( n = 5) a low response expectancy, and Group HLE observed one planarian under each expectancy condition. Group HE reported 18% contractions and 49% head turns in 100 trials whereas Group LE reported but 9% and 9.9%. Group H…
