Experiment 3 Stimuli. There were nine conditions, which were varied in three visible distance levels (Near, Middle, and Far; columns) and three navigational boundary levels (No-Glass-Wall, Curtain, and Glass-Wall; rows). The No-Glass-Wall and Glass-Wall conditions were identical to Experiment 1. In the Curtain condition, a transparent curtain was positioned instead of a glass-wall. The location of the curtain was identical across all visible distance levels. We validated our navigational distance manipulation with a separate set of participants through a behavioral experiment. The SVM classifier was trained and tested to classify across three visible distance levels (Near, Middle, and Far), separately for the No-Glass-Wall, Curtain, and Glass-Wall conditions (separated by a horizontal line).
