The average judged relative distances between the near and far targets in Experiment 1. (a) Dark condition. (b) Parallel-texture condition. All the data points are below the dash horizontal line in each graph, which represents the physical relative distance between the near and far targets. This indicates underestimation of relative distances in both conditions and viewing modes. Nonetheless, the underestimation is least in (b) with binocular viewing and long stimulus duration (5s). This demonstrates the contribution of the relative binocular disparity information between the suspended target and the visible texture ground surface to distance perception.
