Question

Operant conditioning of gill withdrawal in Aplysia

phase 1:
experimental animals received shock when gill withdrawal was less than criterion.
control animals recieved shock everytime exeprimental animals received shock

phase 2:
both control and experimental animals received shock contingent on their own behavior ( when gill withdrawal was under criterion)

cumulative plot shows performance of each animal.

How do we interpret these results ?

100 EXTINCTION 75 0C 50 25 -O- Con Phase l Exp Phase l -A-Con Phase II - Exp Phase lII 0 50 % TIME ABOVE CRITERION 0 25 75 100

Explanation / Answer

The experimental animals spent more time with their gills contracted above the criterion level than did the control animals during each period
