Behavioral paradigm for Experiment 2. At the beginning of each trial there was either a valid cue (50% of the trials) correctly indicating the impending direction of motion, an invalid cue (25% of the trials) incorrectly indicating the impending direction of motion, or a neutral cue (25% of the trials) that contained no directional information whatsoever. Invalid cues indicated directions that were offset from the direction of motion of the target RDP anywhere from ±30° to ±180° on a trial-by-trial basis (determined pseudorandomly within a given block of trials). The target RDP contained 80% motion coherence, while the distractors contained 40% motion coherence, where each distractor direction was offset from the target direction by either ±15°, ±45°, ±75°, ±105°, ±135°, or ±165° (randomly chosen per trial, where each distractor direction was unique) for eight of the subjects or by ±18°, ±36°, or ±72° for the remaining four subjects. Note: Cues in the first panel are exaggerated in size for the purposes of clarity.
