The present study explored the possibility of applying Koppitz's developmental scoring techniques of mental maturity to retarded adults. The following hypotheses were tested: 1) that there is a significant correlation between the Koppitz HFD Test scores and the WAIS Full Scale scores; 2) that the correlation between the Koppitz HFD Test scores and the WAIS Performance Scale scores is also significant. Statistical computations did confirm the latter hypothesis but not the former one.

A one-trial learning color discrimination task was extrapolated from Jarvik's (1953) teaching color discrimination to primates. A yellow-blue discrimination was selected to teach eleven autistic children. As in Jarvik's, SD and SA, reinforcer and punisher, were one and the same. Sugar-flavored water was the S D alum-flavored water, S . The instrumental response of reaching for a colored glass and drinking was established. Then one-trial learning occurred. The learning tests were a block of twenty-five trials for each individual subject on the following day. The second day another block of twenty-five trials was administered to each subject. It was hypothesized that the subjects would function at a ninety per cent criterion level. None of the subjects learned the task.

Fifteen hospitalized adolescents were used as subjects. An individually consequated token economy was in effect during baseline. Measures were taken of work output, attending behavior, and disruptive behavior. During the treatment phase, reinforcement was contingent upon the performance of a randomly selected subgroup. Following the treatment phase, the individual token system was reinstated for baseline-2 measures. The mean performance of the group during baseline was compared to performance under treatment conditions for work output and attending behaviors. In addition, performance of the contingent subgroup was compared to performance of the non-contingent group. No significant t values were obtained. With failure to obtain significant t values, the null hypothesis was not rejected, i.e., the two conditions were not proven significantly different.

The study was designed to find a response on the behavioral level that would be an effective index across subjects for determining when conditioned aversive suppression of a response had been achieved. Ten male volunteers received shock during trials in which they had to smoke. Half of the subjects received a brief but more intense shock when they stopped smoking during a trial. A comparison of these subjects to the others showed their average amount of smoking suppression in pre- and post-treatment rates to be significantly (P < .025) greater. In addition, these subjects showed conditioned emotional responding. It was concluded that this behavioral level response was an effective index for determining when suppression of smoking would occur.

The purpose of this experiment was to study the effect of audio feedback from an electromyograph on reading speed and comprehension. The subject reduced as much audio feedback, and thus laryngeal tension, as possible, thus permitting more efficient reading. After baseline, the subject received twelve half-hour practice sessions, six ten-minute testing sessions on easy, or light, material and six ten-minute testing sessions on difficult material. A post-test without feedback was given after training and a follow-up test, without feedback, was given. This method of training permits a higher rate of reading speed, while allowing the subject to process complex information and maintain a constant level of recall.
