Sensory processing, cardiovascular reactivity, and the Type A coronary-prone behavior pattern

E L Diamond, C S Carver

    Biological Psychology
    |June 1, 1980
    PubMed
    Summary

    Cardiovascular reactivity in Type A individuals was studied using sensory tasks. Contrary to expectations, these tasks did not elicit exaggerated responses in Type A participants, suggesting they may not be challenging enough.

    Area of Science:

    • Psychology
    • Cardiovascular Physiology
    • Behavioral Medicine

    Background:

    • Type A behavior pattern is linked to coronary heart disease.
    • Cardiovascular reactivity is a potential mechanism underlying this link.
    • Sensory processing tasks can elicit cardiovascular responses.

    Purpose of the Study:

    • To test if sensory intake and rejection tasks elicit exaggerated cardiovascular responses in Type A individuals.
    • To compare cardiovascular reactivity between Type A and Type B individuals during specific sensory tasks.

    Main Methods:

    • Recruited 15 Type A and 10 Type B male college students.
    • Assigned participants to sensory intake and sensory rejection tasks.
    • Monitored heart rate, blood pressure, and vasomotor responses during tasks.

    Main Results:

    • Sensory tasks did not differentiate between Type A and Type B groups in cardiovascular responses.
    • Both groups exhibited expected cardiovascular patterns for each task.
    • The tasks failed to elicit the predicted hyperresponsivity in Type A individuals.

    Conclusions:

    • Sensory processing tasks may not be sufficiently challenging to reveal Type A hyperresponsivity.
    • Further research is needed to identify appropriate stimuli for eliciting exaggerated responses in Type A individuals.
    • The relationship between Type A behavior and cardiovascular reactivity requires more nuanced investigation.
