  • Abstract
  • Look Inside

Express saccades are those that have very short latencies of about 100 msec. Fischer and Ramsperger (1984) found that saccadic reaction times (SRTs) histograms have two peaks at around 100 msec and 150 msec in a gap paradigm in human saccades and termed such saccades with fast SRTs at around 100 msec express saccades. In the gap paradigm employed by them, the central fixation point is extinguished 200msec before the peripheral target becomes visible, enabling subjects to prepare to shift their eyes to the target.
