BEHAVIOR STABILITY AND RESPONSE RATE AS FUNCTIONS OF REINFORCEMENT PROBABILITY ON "RANDOM RATIO" SCHEDULES.

A random ratio schedule is one under which every ordinally specified response has the same probability of reinforcement as any other. Data have been gathered at several values of this type of schedule, using a separate group of pigeons for each schedule value and giving prolonged exposure to each value. No simple relationship was found between response rate and reinforcement probability. In general aspect group data from the present experiment agree with those from a single organism study cited. It was shown that 40 to 50 days of exposure to random ratio schedules yields fairly asymptotic response rate data. The tabulated raw data, and the results of some statistical manipulations, have been deposited with the American Documentation Institute.

Effects of chlorpromazine and d-amphetamine on escape and avoidance behavior under a temporally defined schedule of negative reinforcement.

Chlorpromazine hydrochloride and d-amphetamine sulphate were administered to two rats responding on a baseline temporally defined schedule of negative reinforcement which produced both "escape-like" and "avoidance-like" behavior. The effects of these drugs appeared similar to those expected on the more customary sort of non-cued avoidance schedule.

Two parameters of a temporally defined schedule of negative reinforcement.

Temporal schedules of negative reinforcement were derived in a manner analogous to those for positive reinforcement, and two parametric studies were carried out with two of the three defining variables. With some limiting values of the defining variables, escape schedules result and data obtained at these values were similar to those obtained in escape studies. At other values of the defining variables avoidance behavior was generated.
