The ability to assess coincidence-anticipation timing has been hypothesized to rely on various monocular and binocular cues. The most commonly mentioned of these are looming and binocular disparity. The purpose of this study was to compare monocular and binocular assessments of coincidence-anticipation timing on the Bassin Anticipation Timer. This device is intended for clinical testing and training of coincidence-anticipation timing responses. Coincidence-anticipation timing responses were assessed using a button press at five different velocities ranging from five miles per hour to 40 miles per hour. Each subject was tested under three viewing conditions. These conditions were binocular viewing, monocular viewing with the dominant eye, and monocular viewing with the non-dominant eye. Although subjects varied in their responses, overall results suggested that there were no differences in performance under binocular and monocular conditions although 12 subjects demonstrated lesser errors binocularly (compared to the other two conditions) at 40mph. Signed and unsigned coincidence-anticipation timing errors were smallest at higher target speeds (early responses were more common at lower speeds). Those errors at 30 miles per hour were smallest. Results indicate that binocular disparity and monocular looming were not likely to be the main cues subjects used to determine coincidence-anticipation timing responses. Arguments are put forward that target speed may be the most important cue for coincidence-anticipation timing responses on the Bassin Anticipation Timer.
