A BEHAVIORAL-EDUCATIONAL ALTERNATIVE TO DRUG CONTROL OF HYPERACTIVE CHILDREN

A behavioral procedure for controlling hyperactivity without inhibiting academic performance is described. Using a time-sample observational method, the hyperactivity displayed by three school children was recorded during math and reading classes. Concurrently, math and reading performances were measured. The study consisted of two baselines, one while the children were on medication and the second while they were off medication. A multiple-baseline design across the two academic subject matters was used to assess the behavioral intervention, which consisted of token reinforcement for correct academic responses in math and subsequently math and reading. Discontinuation of medication resulted in a gross increase in hyperactivity from 20% to about 80%, and a slight increase in math and reading performance. Introduction of a behavioral program for academic performance, during no medication, controlled the children's hyperactivity at a level comparable to that when they were on drugs (about 20%). At the same time, math and reading performance for the group jumped from about 12% during baseline to a level of over 85% correct. Each child performed behaviorally and academically in an optimal manner without medication. Contingency management techniques provided a feasible alternative to medication for controlling hyperactivity in the classroom while enabling the children to grow academically.     

Extremely long-term persistence of the McCollough effect.

The question has been raised whether an associative mechanism is responsible for the persistence of the McCollough effect. Since current estimates of its rate of decay are derived from procedures in which subjects are repeatedly tested, it was hypothesized that the measured effects might be attenuated by the testing process. Accordingly, a comparison was made between repeated testing and time-elapse testing. A conventional group of 16 subjects had repeated testing at 0, 8, 24, 56, and 120 hr. after induction. Five other groups of 16 were run, each at one of the time delays, with no intervening tests; an additional measure was taken where appropriate at 120 hr. A magenta-green nulling procedure was used to assess the aftereffect. The repeated-test group showed a linear decrease of effect against the stated delays, reaching zero at 120 hr. In contrast, the time-elapse groups showed little decline up to 120 hr. Those groups retested at 120 hr. showed declines due to prior testing. When four more groups were subsequently tested at intervals up to 2,040 hr., the effect remained at better than half strength.     

The effects of overtraining and successive extinctions upon nictitating membrane conditioning in the rabbit

In Expt. I Group SAE (N = 16) received four successive acquisitions and extinctions of a classically conditioned nictitating membrane response while Group OTC (N = 8) received an equivalent amount of acquisition training followed by a single extinction session. Successive extinctions resulted in a decrease in resistance to extinction (Rn), but extended acquisition training had no significant effect. In Expt. II a total of 96 subjects participated in a factorial study of the effects of various amounts of overtraining at two different UCS intensities. When CR amplitude was asymptotic extended training had no significant effect upon Rn; when amplitude was below asymptote Rn was correspondingly reduced.     

Reinforcement contrast effects on the rewarding and aversive components of intracranial stimulation

Rats performing a free-operant locomotor response in a shuttlebox to initiate and then escape medial diencephalic stimulation were tested daily on a randomized sequence of three stimulation intensities. In spite of a 1-hr interval between stimulation intensity changes, substantial and graded reinforcement contrast effects were obtained. “Elation” effects were obtained both on the rewarding (latency to initiate) and the aversive (latency to escape) components of stimulation whereas “depression” effects were found only on the measure of reward.     

Reciprocity counseling: A rapid learning-based procedure for marital counseling

Existing marital counseling procedures have not been experimentally evaluated or generally have not been based on an experimentally derived theory. The present study formulated a model of marital discord based on reinforcement theory, developed a marital counseling procedure based on that theory and experimentally evaluated its effectiveness. The model viewed marital discord as the resultant of non-reciprocated reinforcement. The counseling procedures attempted to establish general marital reciprocity of reinforcement by teaching reciprocity in several specific areas of marital unhappiness. The reciprocity procedure was conducted for about 3–4 weeks with 12 couples, after first conducting a catharsis-type counseling as a control procedure. The results showed that the reciprocity procedure increased reported marital happiness, whereas the control procedure did not. Once reciprocity was achieved in a specific problem area, the benefits generalized somewhat to other yet-to-be counseled areas. The increase in marital happiness occurred for each of the specific areas of marital interaction, for 96 per cent of the clients, and was maintained and increased during the available follow-up period. These results indicate that the procedure is an effective, rapid and enduring method of producing marital happiness.
