Question

A. Hans Selye conducted interviews with human participants identifying their emotional state during different lengths of time living under stressful conditions.
B. Hans Selye conducted a study comparing the cortisol and blood sugar levels in rats before and during a stressful situation.
C. Hans Selye conducted a study measuring cortisol and blood sugar levels in rats during different amounts of time living under stressful conditions.
D. Richard Lazarus conducted a study measuring cortisol and blood sugar levels in rats during different amounts of time living under stressful conditions.
E. Richard Lazarus conducted interviews with human participants identifying their emotional state during different lengths of time living under stressful conditions.

Answer 1

Answer:

B

Explanation:

Hans Selye is regarded as the founder of the theory of stress.

He developed the general adaptation syndrome (GAS) which describes how the body reacts to stress.

The stages of GAS are :

alarm reaction - flight or fight response to stress

resistance - continued exposure to stress leads to higher metabolic response to offset the stress

exhaustion - continued exposure to stress can negatively affect the body and lead to health problems

Hans made this discovery in the 1930s after studying the response of rats after the injection of hormones into them. He compared their cortisol and blood sugar levels in rats before and during the experiment.

He concluded that it was the stress that caused the rat to become ill and die
