Here we show that smooth pursuit eye movement RTs show no effect of SR uncertainty while joystick tracking shows a step change between SRTand CRT, but no significant increases beyond two choices. The results suggest there is a benefit to pre-programming

Regardless of stop signal modality, stop signal reaction time was shorter for eye movements than for hand movements, but notably did not vary with knowledge about which movement to cancel. Most errors on eye + hand stopping trials were combined eye + hand movements. The probability and latency of signal respond eye and hand movements corresponded to predictions of Logan and Cowan's (1984) race model applied to each effector independently.

In fact, the prevalence of grapheme-color synesthesia is currently unknown, with estimates broadly ranging from 0.014% to 4.4% (Baron-Cohen, Burt, Smith-Laittan, Harrison, & Bolton, 1996; Rich,Bradshaw, & Mattingley, 2005; Simner, Mulvenna, Sagiv ... 290 / DOMINGO ET AL. ...

This study addressed the question of whether eye position is used in making perceptual judgments of the relative spatial locations of two successively presented visual targets. ...
