Resource summary

Question Answer
Outline the pituitary-adrenal system The hypothalamus registers the presence of a stressor and stimulates the pituitary gland to release ACTH This activates the adrenal cortex Which then releases cortisol (which suppresses the immune system)
Outline the sympathomedullary system The hypothalamus registers the presence of a stressor and sends an electric signal to the adrenal medulla This releases adrenaline which arouses the sympathetic nervous system Also adrenaline increases sweating and heart rate
Outline Kiecolt-Glaser's study This was a natural experiment using 75 medical students Blood samples were taken: a) one month before exam season and b) during exam season T cell activity was reduced in the second blood sample and in ppts who reported high levels of life events and loneliness
Briefly explain the SRRS It was developed by Holmes and Rahe Consists of 43 life events that ppts checked off if they had experienced them in the past year Holmes and Rahe propsed that a score of 150 or above could increase the risk of stress-health breakdown by 30% and over 300 = 50%
Outline Rahe's study 2500 male American sailors were given the SRRS to assess how many life events they had experienced in the previous 6 months Over the next 6 months, the sailors' health status was recorded There was a +0.118 correlation between life events and illness scores
Briefly explain daily hassles Daily hassles are relatively minor events that arise in the course of a normal day (e.g. traffic or a malfunctioning computer)
Outline research on daily hassles Kanner - devised the hassles scale which has 117 items and also devised an uplifts scale that could have a positive impact on people's stress levels Scores on the hassles scales correlate with levels of depression, anxiety and health problems DeLongis - found that the correlation between daily hassles and illness was stringer than life events and illness
Identify and briefly explain sources of stress in the workplace Physical environment - space, temperature, lighting and arrangement of an office can affect an individual's stress levels Workload- having too much work to do in a limited time can leave someone incredibly stressed Lack of control - a perceived lack of control increases the stress response and contributes to depression and illness Role ambiguity - when the requirements for a particular role are unclear it is a major contributing factor to stress levels
