title: Cognitive response to a cold pressor challenge in high and low blood pressure reactive subjects.
abstract: To examine the relationship between cognitive and cardiovascular reactions to a cold pressor challenge, 20 high and 20 low blood-pressure-reactive males were identified. Subjects were trained using a think-aloud procedure and asked to report their thoughts aloud during task presentation. In comparison to low-reactors, high-reactive subjects exhibited greater increases in systolic and diastolic blood pressure, but not heart rate, in response to the task. High-reactive subjects reported fewer distracting self-statements than low-reactors during the task. No group differences in positive, neutral, or negative self-statements were observed. These findings corroborate the importance of distraction strategies in mediating acute cardiovascular reactions to stress.
