Reward system, is associated with limbic pathway
Activated by reaching goals
Emotional expressions may modulate motivated

Antonio Damasi

certain stimuli
There is no single brain system dedicated to emotions
Automatic Nervous System is activated when in an emotional
situation
o Increased heart rate, blood pressure
James Lange Theory of Emotion
Emotional response occurs after automatic nervous system
response
o Brain reads patterns in automatic nervous system to interpret
current emotional state
o Peripheral Nervous System determines emotional state of
an individual

Document Summary

Defined as a relatively brief display of a feeling made in response to environmental events having motivation significance or in response to memories of such events: changed in emotional states are associated with motivated behaviours. Reward system, is associated with limbic pathway. Antonio damasi: separates feelings from emotions. He argues that emotions are internal reactions that occur automatically and unconsciously in response to certain stimuli. There is no single brain system dedicated to emotions. Automatic nervous system is activated when in an emotional situation: increased heart rate, blood pressure. Emotional response occurs after automatic nervous system response: brain reads patterns in automatic nervous system to interpret current emotional state, peripheral nervous system determines emotional state of an individual. Automatic nervous system is coincidental to emotional state. Physiological changes occur too slowly to trigger emotional reactions and we are not aware of many bodily reactions so we cannot use this information to determine our emotional state.
