Visual perception is of utmost importance to guide our actions in daily life. However, blurring vision also affected temporal precision and accuracy, thereby questioning the generalizability of the theoretical predictions to the applied interception task. Our findings confirm that blurring vision decreases spatial precision and accuracy and that the effects were not mediated by concomitant changes in contrast. We found no systematic effects of contrast. Because in the first experiment, blur was potentially confounded with contrast, in Experiment 2, we re-ran the experiment with one difference: instead of blur, we included five levels of contrast matched to the blur levels.

With increasing blur, the spatial and temporal variable error, as well as the spatial constant error increased, while the temporal constant error decreased. As a measure of spatial and temporal accuracy and precision, we analyzed the constant and variable errors, respectively. Participants were asked to indicate (i.e., finger tap) on a touchscreen where and when the virtual ball crossed a ground line. In Experiment 1, we blurred a virtual, to-be-intercepted moving circle (ball).

To test this, in two experiments, we systematically reduced the acuity and contrast of a visual stimulus and examined the impact on spatial and temporal precision (and accuracy) in a manual interception task. The visual system is said to be especially sensitive towards spatial but lesser so towards temporal information.
