In the presence of a tone/light cue, pigeons were trained to press a foot treadle to gain access to food or to avoid footshock.Subsequent investigations determined that responding in appetitive situations is more likely to be controlled by visual cues; responding in aversive situations by auditory cues.This demonstrates that


A) the type of instrumental response required is a determinant of stimulus control.
B) the sensory capacity of an organism is a determinant of stimulus control.
C) the type of reinforcement is a determinant of stimulus control.
D) the determinants of stimulus control are idiosyncratic.

A training stimulus of a red square inside of a yellow circle was used in a keypeck experiment with pigeons.In a follow-up experiment, one trained pigeon was found to respond more to a red square than a yellow circle.Another trained pigeon responded more to the yellow circle.This demonstrates that


A) stimulus control did not develop in the initial training.
B) stimulus control developed only in the subject responding more to the red square.
C) stimulus control developed only in the subject responding more to the yellow circle.
D) stimulus control can vary from subject to subject.
