The Influence of Figure-Ground and Depth on Attention in a Modified Stroop Task

Post date: Nov 17, 2016 2:41:34 PM

Abstract: Figure-ground and depth cues were examined. Shadows (Experiment 1) produced interference (F(1, 23) = 28.01, p < .001) and slower RTs for occluded targets (F(1, 23) = 9.01, p < .01). Figure-ground images produced interference (F(1, 10) = 7.26, p < .03) in Experiment 2. Linear perspective (Experiment 3) produced interference (F(1, 17) = 15.50, p < .001) and an effect of depth (F(1, 17) = 9.28, p < .01) with longer RTs to closer bars. This finding is not due to perceived size (Experiment 4). Therefore, the effects of occlusion may be mediated by additional depth cues.
