Perceptual effects of microsaccade preparation. (A) Average ($N$ = 6) sensitivity (d′) in different trial types. Performance is also shown for trials in which a saccade cue was presented but subjects did not perform a microsaccade (fixation congruent/incongruent). (B) Performance in neutral trials plotted against performance in congruent trials. The white data point and error bars represent group mean and SEM. The gray circles represent single-subject data. (C) Average manual response times. Error bars are SEM. Asterisks mark a statistically significant difference (*$P<0.05$, Tukey’s post hoc test).
