- 1Outline the pituitary-adrenal systemThe 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) - 2Outline the sympathomedullary systemThe 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 - 3Outline Kiecolt-Glaser's studyThis 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 - 4Briefly explain the SRRSIt 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% - 5Outline Rahe's study2500 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 - 6Briefly explain daily hasslesDaily hassles are relatively minor events that arise in the course of a normal day (e.g. traffic or a malfunctioning computer)
- 7Outline research on daily hasslesKanner - 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 - 8Identify and briefly explain sources of stress in the workplacePhysical 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
