Abstract
A gap between fixation target offset and saccade target onset encourages the production of express saccades (ES; latency 80-130ms). “Express saccade makers” (ESMs) produce almost exclusively ES in gap trials, and in overlap trials (fixation target present when the saccade target appears), a large proportion (>30%) of their saccades are ES. We investigated performance stability in ESM and nonESM participants over time and the effect of repeated exposure to gap and overlap tasks. Experiment 1. 113 participants (59 ESMs) completed two blocks of 200 overlap trials in the first session (T1). Sixty provided data on a second occasion (T2; 27 ESMs; 200 trials; mean of 87 days later) and 30 provided data on a third occasion (T3; 13 ESMs; 200 trials; mean of 94 days later). Eye movements were recorded using an infrared reflectance eye tracker. For each participant, the percentage of saccades with latencies of 80ms to 130ms (%ES) was calculated for all saccades with latencies between 50ms and 500ms. Participants displayed the same relative performance both within (T1, Block 1 vs 2: ICC=0.97, p
