FIG 3.

Orientation acuities for CW/ACW judgments with respect to horizontal for CG (a) and JAS (b). Dotted and dashed lines reflect acuities for upward and downward drifting targets, respectively, without distractors. Different columns reflect different conditions, e.g. “U/D” is the condition in which the target drifted up and the distractors drifted down. Each column summarises a minimum of 120 trials. Error bars contain 95% confidence intervals. Acuity was worst when target and distractors shared the same direction of drift.
