Effects of extraversion and mental arithmetic on heart-rate reactivity
1Old Dominion University, Norfolk, VA 23529-0267.
Abstract:
The purpose of the present study was to examine the effect of extraversion and task difficulty on heart-rate reactivity. 15 extraverts and 15 introverts as identified by their scores on the Eysenck Personality Inventory completed mental arithmetic problems of three levels of difficulty. Two-way analysis of variance indicated that heart-rate reactivity increased as task difficulty increased. Also, introverts showed larger heart-rate reactivity to the task than extraverts. The present findings partially support Eysenck's physiological theory of extraversion in that introverted subjects were more aroused by the mental arithmetic task; however, the factors which produce such a difference are unclear.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
