Emotion 

Emotions are reactions that human beings experience in response to events or situations.

Key Elements:

1. The subjective experience - your own experience of these emotions may be much more multi-dimensional, hence subjective.
2. The physiological response - emotions also cause strong physiological reactions.

The autonomic nervous system controls involuntary body responses such as digestion and blood flow.

The sympathetic nervous system controls the body’s fight or flight reactions.

The amygdala plays an important role in emotion and fear.

Emotional intelligence refers to the ability to identify and manage one's own emotions, as well as the emotions of others.

Theories of emotion

Darwin’s Evolutionary Theory of Emotion : suggests that emotions are adaptive to our environment and improves our chances of survival.

The James-Lange Theory : our physicals responses are responsible for emotion.

Perception of the angry bull → Physiological reactions → Feeling of fear

= I am scared because my heart is racing instead of my heart is racing because I am scared.

The Schachter-Singer Theory : suggests our thoughts are actually responsible for emotions. We perceive a situation as threatening so we experience fear.
