Scenario II
The below model of emotion is based on the following work:
LeDoux,J.E.(2000).Emotion circuits in the brain.Annual Review of Neuroscience,23,155-184.
The psychologist Joseph LeDoux tracked the neural mechanisms underlying the fear response in rats.Rats were exposed to the sound of a tone followed by an electric shock.After a few tone-shock pairings,the tone elicited species-typical defense behaviours such as freezing and increased sympathetic activity (e.g. ,an increase in heart rate).Using this fear-conditioning paradigm,LeDoux argued for the existence of both fast and slow neural pathways underlying the fear response.A particular brain structure (arbitrarily labelled "A")simultaneously routes sensory information to structures B and C.In the fast pathway,information is routed to structure C-a limbic structure long known to be involved in emotional experiences such as fear-where it is rapidly assessed.If appraised as a threat,structure C activates the fear response.In the slow pathway,information travels to other structures in the brain (labelled "B")involved in planning and more advanced decision making.The results of the appraisal by structure B is used by structure C to continue or terminate the fear response.
-(Scenario II)In this fear-conditioning paradigm,what constitutes the unconditioned stimulus?
