Figure-Ground or Depth Processing?

Christopher Koch & Elissa Shinseki

Abstract: This study examined the role figure-ground and depth on the color block Stroop task. In Experiment 1, one color block was presented vertically and one was presented horizontally. The vertical and horizontal bars served as occluders an equal number of times. Incongruent pairs produced longer RTs than control trials. RTs were longer when the target was occluded. A shadow was used to increase perceived distance between blocks in Experiment 2. Results were similar to Experiment 1. In Experiment 3, linear perspective was used to create depth. Incongruent pairs had longer RTs but bars closest to the subjects produced longer RTs.
