Extinction and recovery of the discriminative stimulus effects of nicotine (0.3 mg/kg) was investigated with a devalued food reinforcer (rats sated). Sixteen rats were trained in a counterbalanced one manipulandum (nose-poke) drug discrimination procedure with the roles of nicotine and saline counterbalanced as S[superscript D] and S[superscript…

Statistically, haloperidol was significantly superior to placebo in reducing behavioral symptoms. In a discrimination learning paradigm, autistic children receiving haloperidol learned the discrimination while those on placebo did not. Discrimination attained on haloperidol was retained when the children were switched to placebo. (Author)

The free play of 5 black preschool Head Start children was observed. The variables manipulated in the study were delayed instructions and reinforcement for play with selected toys, and specific versus general instructions; the correspondence between the adult's instructions and reinforcement to the children's play was assessed. The data indicated…

In an experiment to test the effectiveness of discrimination training--contrasting good and poor teacher behaviors and demonstrating the stimulus occasions for these behaviors--as compared with feedback from an instructor in microteaching, a discrimination model for a limited class of teaching behaviors was devised and subjects were divided into…

The present investigation was conducted to determine if stimulus overselectivity in 19 autistic children (5 to 12 years old) is changed as a function of repeated exposure to testing. (Author/SBH)

The double-blind and placebo controlled study with 45 autistic children (ages 2-7) found that the drug, haloperidol, showed powerful therapeutic effects in reducing behavioral symptoms when administered for 4 weeks at doses raging from 0.25 to 4.0 milligrams/day. Learning effects were not found. (Author/DB)

The study evaluated the usefulness of 48 hours of Restricted Environmental Stimulation Therapy (REST) as a treatment for eight autistic children (between 5 and 11 years old). Ss were placed in a dimly lit room which contained only a mattress, told to ask for toilet facilities when needed, and then left alone except for when meals were brought in.…

Discussions about transfer have mainly dealt with how people manage to do something in a situation thanks to having done something similar in a previous situation. From an educational point of view, however, it appears more fruitful to consider the case when the learner, having learned to do something in 1 situation, might be able to do something…

As a result of findings of a previous study, this study, which sought to program preschool subjects to wait one minute for reinforcement, used pause-building procedures before delay conditions were started. The children, 3- to 5-year-olds, were designated either Baseline (control) subjects (n=3) or Programmed (experimental) subjects (n=5). Though…

Through an experimental analysis, this study demonstrates characteristics of both observer-produced and punishment-produced suppression of cheating behavior. The research procedure, designed to eliminate the interpretative difficulties of prior, comparable research, is fully elaborated. Two delinquent, retarded, adolescent boys served as subjects.…

This study investigated the effects of between-trials variability on the alternation discrimination of retardates. Brightness and size were variable between trials and irrelevant. Initial response outcome and mental age were also independent variables. Neither between-trials variability nor mental age produced a significant main effect, while the…
