Failure to integrate visual information from successive fixations

Abstract

After a 200-msec exposure to 12 dots from a 5 × 5 array, subjects made 4-deg saccades during a 37-msec blank interval, and then saw another 12 dots from the array for 17 msec. Subjects failed to identify the location of the missing dot, contradicting the conclusions of Jonides, Irwin, and Yantis (1982). Performance was also at chance levels with a 2.25-deg saccade, eliminating the possible effect of saccadic suppression of displacement. Screen brightness (2 log units above threshold) eliminated the phosphor persistence that probably accounts for the success of Jonides et al.’ s subjects. © 1983, The psychonomic Society, Inc..
