Margaret Intons-Peterson manipulated experimenter expectancies by suggesting to one group of experimenters that task performance would be expected to be better for perceptual tasks than for imaginal ones. She suggested the opposite outcome to a second group of experimenters.

Thus, experimental participants performing visualization tasks may be responding in part to the ____ of the task.
a. perceptual difficulty
b. matching variables
c. demand characteristics
