The initial experiment with a compound CS (Exercise 6) showed that the amount of conditioning of each of the component CSs was approximately half that of the compound CS. Which aspect of the overexpectation experiment (Exercise 9) best parallels that earlier finding?
a. The essentially equal amounts of conditioning of each of the CSs when they were paired separately with the US before being combined (Stage 1)
b. The high amount of conditioning of the compound CS when it was first presented (Stage 3)
c. The fact that the amount of conditioning of the compound CS changed very little across the trials in which it was paired with the US (Stage 3)
d. The essentially equal amounts of conditioning of each of the CSs when they were presented separately in extinction after having been compounded (Stage 4)
d. The essentially equal amounts of conditioning of each of the CSs when they were presented separately in extinction after having been compounded (Stage 4)
Answer feedback: In Stage 4, the amount of conditioning of the light and tone was approximately the same, as displayed in both the Movement Ratio and CS Response Strength Windows. In addition, this amount was approximately half of what it had been for the compound CS.
