In thefirst two experiments, pulse direction identification performance was higher when theremembered direction (FBWM) or the direction of the concurrently attended RDP (FBA) matched the pulse direction thanwhen it was opposite. InExperiment 3, performance was highest when both the remembered and the attended directionsmatched the pulse direction (combined effects of FBWM and FBA), it was intermediate when only one of them matched thepulse direction, and it was lowest when neither matched the pulse direction. Our results demonstrate that both feature-based working memory and feature-based attention can individually modulate the perception of motion direction and thatwhen acting together they produce an even larger modulation.</p>
