Fig. 9.

Similarity of eye positions for switch and nonswitch presentations (in each case the fourth in the sequence). The average eye positions at four different times are shown for horizontal position (A) and for vertical position (B). The four time points (0, 100, 200, and 300 msec after image onset) for the times of the eye position measurement correspond to our analysis period of 100–400 msec after image onset, allowing for a 100 msec latency from image onset to IT response. These data are averaged across all 78 of our main group of 92 units, for which the eye-position data were retained.
