The area most widely associated with osmoreception has been the lateral preoptic nucleus. However, Hatton (1976) proposed that the nucleus circularis could be the actual osmoreceptor in the hypothalamus. The present study supported Hatton by using 30 rats which were randomly assigned to sham, lateral preoptic, and nucleus circularis lesion groups. After a 2-week post-operative period, half of each group was injected with isotonic saline while the other half was injected with hypertonic saline. Water consumption was measured at 10-minute intervals for one hour. Following a 4-day recovery period, the injection procedure was reversed. Analysis of difference scores, computed by subtracting the amount of water consumed after isotonic injection from the amount of water consumed after hypertonic injection, revealed a significant difference between the nucleus circularis group and the other two groups.

Silverman's technique of subliminal psychodynamic activation via tachistoscope has been demonstrated to facilitate competitive performance in college males when a sanctioned oedipal gratification fantasy stimulus is utilized. This effect is presumed to result from a decrease in unconscious neurotic conflict. The cognitive component of Meichenbaum's Cognitive Behavior-Modification has been shown effective in reducing test anxiety. This effect is presumed to stem from conscious identification and modification of negative self-statements. The hypothesis that a combination of the two approaches would prove more effective than the cognitive group therapy alone in reducing test anxiety was tested. Thirty-four test-anxious male students attended 10 sessions wherein they received subliminal stimulation and cognitive group therapy. Half of the students were presented active, and half neutral stimuli subliminally via tachistoscope. All received the cognitive group therapy. Therapists conducting the groups were blind to the hypothesis being tested and the assignment of subjects to experimental and control groups. Subjects were randomly assigned to the experimental conditions in order to control for group and therapist effects.

The purpose of this project was to clarify the methodological considerations involved in the posttreatment follow-up evaluation of alcohol-abuse patients. A two-part project was undertaken in an attempt to answer the follow-up questions of how and when to measure treatment effects with discharged alcoholics. In Part I, a large-scale survey was utilized to examine return rates across various program evaluation methods and time frames. In Part II, the predictive validity of scores received at short-term follow-up in relation to scores received at 1-year follow-up was assessed for measures of psychosocial functioning and alcohol consumption.
