Questions and Answers
What concept has psychology taken over from common usage but has been difficult to handle experimentally?
The concept of emotion.
What did Cannon demonstrate in his experiments regarding extreme stress situations?
Cannon demonstrated that in emergency situations, there occurs a widespread syndrome of specific reactions involving the circulatory, respiratory, and digestive systems, primarily mediated by the autonomic nervous system and a hormone of the adrenal glands.
What has been the result of attempts to correlate emotional states with specific situations and bodily changes?
The results of these investigations have often been contradictory or, at best, inconclusive.

Study Notes
Stress and Emotions
- The concept of "stress" has been taken over from common usage but has been difficult to handle experimentally in psychology.
Walter Cannon's Experiments
- Walter Cannon demonstrated that in extreme stress situations, the sympathetic nervous system is activated, leading to the release of adrenaline.
- This response prepares the body for "fight or flight".
Correlating Emotional States with Bodily Changes
- Attempts to correlate emotional states with specific situations and bodily changes have been inconsistent and unsuccessful.
- This is due to the complexity of emotions and the variability of bodily responses.
Physiological Responses to Stress
- The "fight or flight" response to extreme stress situations is primarily mediated by the sympathetic nervous system.
- This response is characterized by increased heart rate, blood pressure, and energy levels.
Correlating Stress Situations with Bodily Syndromes
- Abundant experimentation has shown that there is no consistent correlation between specific stress situations and bodily syndromes.
- Each individual's response to stress is unique and can vary greatly.
