Emotions and Physiology - Soo and Evelyn


Here's is a (slightly boring) video about the physiological responses to emotion. It talks mainly about endocrine system.


Emotion and Psychology

Emotion: both psychological and physiological
Easy to notice physical responses: muscles tensing, mouth becoming dry, etc.Emotions and Physiology - Soo and Evelyn - The Neuron
Less easy to notice physical responses: liver pours extra sugar into bloodstream, resporation increases, digestion slows, etc.

Autonomic nervous system

Sympathetic division (arousing):
pupils dilate, salivation decreases, skin perspires, respiration increases, heart accelerates, digestion inhibits, adrenal glands secrete stress hormones

Parasympathetic division (calming):

pupils contract, salivation increases, skin dries, respiration decreases, heart slow, digestion activates, adrenal glands decrease secretion of stress hormones

- when crisis urges, the sympathetic division is active, and after crisis passed, the parasympathetic division becomes active.
- too little arousal can be disruptive as extremely high levels.
- performance is best when we are moderately aroused
- easy tasks are best performed with relatively high arousal
- difficult tasks are best performed with relatively low arousal
- anxious students perform more poorly than confident ones.

The Physiology of Specific Emotions

Different emotions show different facial expressions though other physical responses may be similar: fear and rage cause increased heart rate but stimulate differeEmotions and Physiology - Soo and Evelyn - The Neuronnt facial muscles.However, scientists have discovered that different areas in brains secretes associated hormones based on different emotions.
For example, when someone feels "joy," he/she produces a "smile" as muscles in the cheek and under the eye are stimulated.

Not only do physical responses vary for emotions, but also do the brain circuits involved in them. The limbic system affects much of our emotions, as stimulating specific areas of the limbic system can arouse corresponding emotions.

Negative emotions and personalities (including disgust and depression) involve more activity in the right prefrontal cortex than in the left. Positive emotions and personalities (that of infants and motivated adults) involve more activity in the left frontal lobe than in the right. This relates to the fact that the left frontal lobe is rich in dopamine receptors (you should know what dopamine does from chapter 2! but just in case, it affects movement, learning, attention and emotion).

Although certain emotions come with similar physical responses such as those dealing with heartrate, our brain structures allow for those emotions to be unique to every one of us.

Something interesting...Emotions and Physiology - Soo and Evelyn - The Neuron
Charles Whitman was a student at the University of Texas who in 1966 killed his mother, his wife, and 14 other people at the university. He also wounded 31 others in the process. He himself realized that there was something wrong with him and kept a diary in which he expressed that he is having "unusual and irrational" thoughts. After being shot dead by the police, an autopsy revealed a tumor in his limbic system, which seems to account for his unusual thoughts. Whitman was aware that what he was feeling, thinking and doing was wrong and weird but could not control them. After killing his mother and wife Whitman wrote that he wishes for his life insurance money to be donated to a mental health foundation to prevent similar tragedies from happening in the future.
