Basic Reading
This course is not organised around a textbook. I shall refer primarily to material in journals. Also consult basic health psychology texts such as
EP Sarafino 2002 Health Psychology: biopsychosocial interactions (4th Edition)
S Taylor (2003) Health Psychology (5th Edition)
The is also an excellent by old book on the topic
A Steptoe (1981) Psychological factors in cardiovascular disorders.
Steptoe has also written a very good chapter on “Psychophysiological bases of disease” in Johnston & Johnston, Health Psychology, volume 8 of Bellack & Hersen Comprehensive Clinical Psychology
Cardiovascular measures
Heart Rate (HR): Number of cardiac cycles per minute
Systolic Blood Pressure (SBP): Maximum blood pressure in a cardiac cycle
Diasystolic Blood Pressure (DBP): Minimum blood pressure in a cardiac cycle
Mean Arterial Pressure (MAP): Average blood pressure over a cardiac cycle
Cardiovascular measures (cont.)
Stroke Volume (SV): Amount of blood pumped in a cardiac cycle
Cardiac Output (CO): Amount of blood pumped in unit of time
CO = SV x HR
Total Peripheral Resistance (TPR): The total resistance in circulatory system to the flow of blood.
MAP= CO x TPR
Autonomic Nervous System- seriously simplified
Sympathetic Nervous System - quite diffuse
Neurotransmitter Noradrenaline
Receptors Adrenoreceptors
Beta - Heart - Increase HR & Contractility
Alpha - Smooth Muscle (e.g, vasculature) -
contract small blood vessels
Parasympathetic Nervous System- quite specific
Neurotransmitter acetylcholine
Receptors cholinergic
Heart- slows heart rate, minor effect on Contractility
Effects of Cortisol
Neuron Enhanced catecholamine synthesis
Hippocampus Enhanced memory function
Thalamus Increased sensitivity to incoming stimuli
Adrenoreceptors Enhanced receptor sensitivity
Adrenulla Medulla Enhanced catecholamine synthesis
Immune system Enhanced & inhibited
Glucose Enhanced production
Fatty acid Enhanced liberation
Kidney Water diuresis & sodium retention
