In order to test Eysenck's hypothesis that introverts would condition faster than extroverts, twenty undergraduates were given muscle tensing and muscle relaxing trials using a feedback myograph to obtain electrical activity levels of the frontalis muscle. The subjects were divided into two groups of ten each. The Myers-Briggs Type Indicator was used to select ten students classified as introverts and ten classified as extroverts. .Both groups were given forty thirty-second trials to learn muscle relaxing and tensing. Analysis of covariance indicated a significant within trials effect for both the relaxation and tensing trials. No significant differences were found, however, between the introverts and the extroverts in either the muscle relaxing or muscle tensing training.

The hypotheses investigated were (1) as measured by a test of impulse control, elopers are more impulsive than non-elopers, and (2) as measured by a test of impulse control, males are more impulsive than females. The Self-Report Test of Impulse Control (STIC) and the Barratt Impulsiveness Scale (BIS) were administered to 76 female and 40 male patients at the time of admission to an open psychiatric hospital. Of these, 20 females and 10 males eloped. The first hypothesis was only partially supported. The second hypothesis was not supported. The BIS was found to be a potential predictor of elopers. The data also suggested that males elope later than females.

An investigation of concurrent validity of the Non-ah Speech Disturbance Ratio (Non-ah SDR) with the State Form of the State-Trait Anxiety Inventory (STAI). Twenty male college students talked on an anxiety-arousing topic before female audiences who rated observed anxiety. Each subject completed the State and Trait Forms of the STAI. Reliabilities were, by the Intraclass correlation for Raters on Day 1, .63 (p<.01) and Day 2, .20 (p<.05). Pearson's r for scorers was .98 (p<.01). The Non-ah SDR and all other measures of anxiety correlated. A partial correlation test found the naive ratings significantly determined by manifest speech disturbance, as measured by the Non-ah SDR. Certain categories of speech disturbance were only infrequently utilized and added little to the measure as a whole.
