Minimum Number

Two procedures were evaluated in terms of their ability to modify the slowed responding of schizophrenics under an FR 40 schedule. FR 40 response rates increased when schizophrenics were instructed to earn a minimum number of reinforcements or to imitate the rate of responding of someone shown earning that minimum number of reinforcements. The greater increase in FR 40 responding occurred under the latter procedure.

Delay Of Reinforcement

15 human Ss received alternating sequences of 0- and variable 15-sec. delay of reinforcement on a FR 15 schedule lever-pulling task. Groups of 5 Ss received either rate instructions to maximize reinforcement or correct responses, or no instructions. Results indicate that delay of reinforcement reduced response rates only for Ss with rate instructions.

Lever Pressing

To determine whether auditory stimuli can control operant responding in mute autistic children, 4 Ss were presented with 5 pairs of auditory stimuli. During the presentation of 1 stimulus the child was able to obtain food on a previously established fixed-ratio schedule of lever pressing, while during the presentation of the second stimulus an extinction schedule was in effect. A new set of stimuli was introduced when the preceding set was learned. 3 of the 4 children learned to discriminate four pairs of auditory stimuli within an average of 36 daily 40-min. sessions. The data indicate that some mute autistic children are capable of learning simple auditory-motor associations.

ABSTRACTAn operant conditioning technique was used to determine whether the reinforcement value of grains and seeds preferred by sheep could be increased by crushing the food. Five sheep were trained to press a plate to receive a food reward. The rate of pressing on a progressive fixed ratio schedule of reinforcement was used as a measure of reinforcement value. Five foods were tested: barley, wheat, oats, lupins and peas. Crushing the foods had no effect on rate of pressing, whereas there was a great deal of variation between sheep and between foods. The preferred foods were wheat and barley.
