Inquiry mode, occupational stress, and preferred leadership style among American elementary school teachers.

The relationship between teachers' cognitive styles and the kind of leadership style they prefer and the types of occupational stress they experience was explored by obtaining self-reports from 70 elementary school teachers. Analytic teachers preferred principals who were task rather than relationship oriented. Preferences in leadership style appeared to be related to subjects' tendencies to perceive and evaluate situations in particular ways. Compatibility with a principal's leadership style may have depended on how closely the style matched a teacher's fundamental affective and cognitive characteristics.

The relationship between aerobic activity and cognitive performance under stress.

This study examined the relationship between regular aerobic activity and cognitive performance under stress when personality and inherent aptitude were statistically controlled. Aerobically conditioned subjects have been shown to mediate the physiological response to stress under physical challenge. Would aerobically conditioned subjects also respond more efficiently to psychological stress under cognitive challenge? Forty volunteers completed a battery of personality and aptitude measures and then completed two cognitive tasks (written tests of logic), one under a condition of no stress, the other while being verbally pressured by a test monitor. Heart rate and blood pressure were measured during and after each cognitive task. Contrary to the experimental hypothesis, aerobic activity was related to inferior cognitive performance and to elevated blood pressure under stress. Inherent cognitive aptitude and personality traits emerged as far more important correlates of cognitive performance under stress than did the level of exercise.

Addictive personality factors.

This study was designed to compare mean scores obtained by alcoholics, compulsive gamblers, smokers, chronic joggers, and control subjects on six subfactors of the MacAndrew Alcoholism Scale. Results indicated that some MacAndrew factors may be more sensitive to additive pathology than others. Alcoholics emerged as the most pathological group, in terms of scores on the Cognitive Impairment, Social Maladjustment, and Risk Taking scales. Gamblers and smokers appeared to be distinctly different, more socially oriented addicts. Frequency of jogging was negatively related to measures of addiction but positively related to measures of compulsiveness.
