Question 2

The observer's task was to respond whether or not the two pictures were the "same" or "different." The response time was longest for

Accepted Answer

A)  breaking point. 
B)  segment marker. 
C)  event boundary.

Question 14

An afterimage when viewed in the dark appears to move when you move your eyes. The Corollary Discharge Theory predicts this because

Accepted Answer

A)  there is an IDS, but not a CDS. 
B)  there is no IDS, but there is a CDS. 
C)  there is no IDS and no CDS. 
D)  none of the these; the corollary discharge theory cannot explain this event.
