Free Operant Situation

Rats were trained to bar press for food reinforcement in a two-bar multiple fixed-ratio situation. After the animal had established asymptotic rates of time for transferring between bars and responding on each bar, responding on one bar led to no reinforcement or random intermittent (50%) reinforcement. Responding on a second bar was always reinforced. Under both schedules of reinforcement, rats decreased their time to transfer to the second bar and their time to respond on the second bar. All animals also displayed an initial disruption of transfer back to and responses on the first bar. For rats on the intermittent reinforcement schedule, the decreased response time on the reinforced bar was primarily found after nonreinforcement of response to the previous bar. Reinforcement schedules for response to the first bar did not differentially affect the above behavior.

Reversal Shift

Drive level affected reversal rather than non-reversal-shift learning during initial shift-discrimination trials. Animals under high water deprivation during the original simultaneous discrimination and reversal-shift discrimination made more initial (first trial-block) errors during reversal-shift than animals that were maintained on moderate deprivation during either or both discrimination tasks.

Food Consumed

A total of 48 albino rats were observed over a 15-day period to determine the effects of drive level, maturation, and practice level on eating latency, amount of time during a 5-min. interval spent in eating, amount of food consumed, and rate of eating. In general, the effects of maturation and practice followed expected lines, with facilitation of consummatory behavior accompanying both maturational and experiential development. Although higher-drive Ss have shorter latencies and spend more time eating, they consume less food per unit of time spent in mastication than lower-drive Ss.

Better Than

Moderately (18 hr.) water-deprived rats were able to utilize an incidental cue of floor-texture following learning of brightness of a goal door better than highly water-deprived (23.5 hr.) animals only when water and sucrose liquids were paired with attributes of the new cue. These findings along with results from three subsidiary experiments indicate that drive level influences utilization of incidental cues by determining the differential incentive value of rewards predicted by attributes of those cues. This formulation is contrary to the drive level-focus of attention model of Tolman (1948) and Easter-brook (1959).

Avoidance Responses

Six albino rats responded by lever-pressing to avoid grid shock in a free-operant, signaled avoidance situation. Tone cessation was the warning signal for 3 Ss while tone onset was the warning signal for a fourth S. The distribution of avoidance responses during successive reductions of the response-to-warning signal interval indicated a temporal discrimination during the warning signal. Immediate stimulus control, i.e., occurrence of the greatest amount of avoidance responses immediately following the occurrence of the warning signal, was not observed.
