What Was the Important Discovery in Moran and Desimone's Study

Multiple Choice

What was the important discovery in Moran and Desimone's study on attention, which involved recording the activity of individual neurons in the monkey visual cortex while attention was shifted within each cell's receptive field?

A) It showed that if attention was focused on the preferred stimulus the cell produced a variable number of action potentials, depending on what the stimulus was.
B) It showed that when attention was focused on the preferred stimulus the cell produced few action potentials but when attention (not gaze) was shifted, the stimulus provoked far more action potentials.
C) It showed that when attention was focused on the preferred stimulus the cell produced many action potentials, but when attention (not gaze) was shifted, the stimulus provoked far fewer action potentials.
D) It showed that the cell produced few action potentials regardless of whether the attention was on the preferred or ineffective stimulus.
