Neurobehavioral studies of human and animal temperament have shed light on how individual personality traits influence human actions. This approach, however, leaves open questions about how the entire system of traits and temperaments function together to exercise control. To address this key issue, I describe a cybernetic model of control and then apply it(More)
BACKGROUND Interviewing and the physician-patient relationship are crucial elements of medical care, but residencies provide little formal instruction in these areas. OBJECTIVE To determine the effects of a training program in interviewing on 1) residents' attitudes toward and skills in interviewing and 2) patients' physical and psychosocial well-being(More)
PURPOSE To use a controlled, randomized design to assess the effect on patient satisfaction of an intensive psychosocial training program for residents. METHOD Twenty-six first-year residents, in two internal medicine and family practice community-based programs affiliated with the Michigan State University College of Human Medicine, were randomly(More)
In a rare study of effectiveness of an interviewing method, we previously reported a randomized controlled trial demonstrating that training in a step-by-step patient-centered interviewing method improved residents' knowledge, attitudes, and skills and had a consistently positive effect on trained residents' patients. For those who wish to use this(More)
Automated non-invasive recorders allow repeated measurement of blood pressure, 24 h a day; the question of how often to sample blood pressure remains unanswered. Interrupting the patients for a reading more often than necessary may elevate blood pressure or compromise patient cooperation. Thirty-two normotensive subjects were each monitored for 24 h at two(More)
This study prospectively tested the hypothesis that patients with periodic limb movement disorder (PLMD) have longer motor conduction latencies than normals. Six healthy adults, 13 patients with PLMD, and 8 patients with long-term multiple sclerosis (MS) had recordings of motor conduction latencies during wake and sleep. MS subjects were included only to(More)
Thirty-six normotensive adults received laboratory stress testing (mental arithmetic, short-term memory, isometric handgrip, cold pressor tests) and 24-hour ambulatory blood pressure monitoring on two work days separated by a month. Laboratory and ambulatory measures of cardiovascular reactivity had low test-retest reliability. Increases in blood pressure(More)
Sixty subjects classified as either Type A or Type B interacted in pairs by pressing buttons which transmitted messages through a television screen while the heart rate and digital blood volume pulse were computer-monitored. Partners could cooperate, compete, punish, reward, or withdraw on each interaction and could send 1 of 55 messages communicating(More)
