    Notes: The purpose of this study was to assess both coronary-prone behavior and physiological responses to stress in adult women. Forty-one women, aged 25–55, were tested; half were professional or executive-level employed women, the remainder were housewives. Based on the Jenkins Activity Survey, the working women scored as strong Type A's; the housewife group contained both A's and B's. The heart rate, blood pressure and skin conductance responses were compared for these groups while they rested, performed math problems, and attempted to solve visual puzzles. Type A women showed higher heart rates and larger increases in systolic and diastolic blood pressure; Type B women showed larger phasic heart rate decelerations. Employment was not a prerequisite for increased cardiovascular responsivity in Type A's; however, the unemployed Type A's indicated a desire to work. Given the similarities between employment status, Type A behavior and physiological responses in these working women as compared to men, their risk for coronary heart disease may also be similar.

    The Effects of Conflict on Tonic Levels of Blood Pressure in the Genetically Borderline Hypertensive Rat (1980)

    Notes: Studies of aversive conditioning in animals have seldom elicited tonic elevations in blood pressure (BP) equivalent to those which produce pathological changes in humans. While it is possible that psychological factors are not that important in the etiology of hypertension, it is also possible that the failure to elicit large tonic elevations in BP in animals may be due either to stressors which are insufficiently potent and/or to an inadequate physiological model. The present study sought to maximize the probability of producing large tonic changes in BPs by using a conflict paradignt in a genetic strain of rats which develops systolic BPs in the borderline hypertensive area (c. 150 mmHg). Forty-eight male F1 generation offspring of spontaneously hypertensive rats mated with normotensive controls were randomly split into three groups: experimental (subjected to 3 weeks of avoidance training and 12 weeks of conflict in conditioning cages), mild restraint control (placed in conditioning cages daily but not shocked), and maturation control (neither shocked nor restrained) groups. Animals subjected to conflict gradually developed tonic levels of systolic BP well into the hypertensive range (c. 185 mmHg). Restraint control animals also showed some elevation (c. 165 mmHg), but maturational controls showed no change (c. 150 mmHg). The saliency of this animal model for the study of stress-induced hypertension is discussed.

    Notes: Abstract Forty-one male and female children were tested for Type A (coronary-prone) behavior using the Bortner test and the MYTH questionnaire. Based on their classification as A or B, three physiological variables were compared: systolic blood pressure (SBP), heart rate (HR) (phasic, tonic, and variability), and skin conductance (SC) (magnitude and latency of responses, number of spontaneous responses) during a 3-min rest period, a 10-min unsignaled reaction time (RT), and a 10-min word task. When using the Bortner to classify groups, Type As showed a tendency toward higher SBP levels and greater SBP reactivity to tasks, and significantly greater HR levels, HR reactivity to tasks, HR variability during rest, and SCR magnitude to RT signals. When using the MYTH, Type A females showed larger increases in SBP and HR to tasks, a lower mean HR, and a faster RT. Type A males showed a higher mean HR. Thus, children classified as Type A resemble Type A adults when compared on physiological responses to stress; however, the results depend on the method used to determine Type A behavior.
