Emotion
What is emotion?
• A behavior with the following 3 components: (a) a subjective thought and/or
experience with (b) accompanying patterns of neural activity and physical arousal
and (c) an observable behavioral expression (eg. an emotional facial expression)
Physiology of Emotion
• The Initial Response
o Amygdala – a group of nuclei in the medial portion (near the middle) of
the temporal lobes in each hemisphere of the brain
• The Autonomic Response
• Emotional Response
• Emotional Regulation
Experiencing Emotions
• James-Lange theory of emotion – suggested that our physiological reactions to
stimuli (eg. a racing heart) precede the emotional experience (eg. fear)
o Also claims that your feeling of fear is determined by how your body
responds
o According to this theory, emotion would be experienced in the following
way:
▪ (1) based on your initial perception of a stimulus, your heart starts
to race,
▪ (2) your brain receives feedback about that response, and then
▪ (3) the brain decides that based on the feedback it has received,
you should feel fear
