The aim of this research was to examine the temporal limits of binocular and monocular integration useful for one-handed catching. Participants performed 20 one-handed catching trials in 12 conditions (N = 240) defined according to the type of viewing (binocular, monocular) and the manipulation of the visual sample (continuous, intermittent). Catching performance deteriorated significantly when there was no visual information available for 80 ms between 20-ms visual samples provided simultaneously to each eye. However, there was no change in catching performance when continuous monocular vision was available for 80 ms between the binocular samples. Performance under monocular viewing decreased significantly when intermittent samples were separated by less than 20 ms. These results confirm that the equivocality in previously reported temporal limits of binocular integration is due to the different arrangement of the intermittent vision conditions and hence the information available between intermittent samples.
