Regional Effects of Attention from Experiment 1. (A,C) The mean sensitivity of the 44 regions per eye obtained without the foveal attentional task for (A) white, and (C) yellow stimuli. Each region indicates the mean sensitivity computed across the 16 subjects, 2 pupils and 2 eyes. Before averaging, data from right eyes was flipped left to right so that they are left-eye equivalent, thus the temporal visual field is on the left. The mean responses were quite similar for white and yellow stimuli. (B,D) The mean effects (differences) produced by attention at each region (Δ Attention). The data are the terms of region by attention from the same linear models that generated the data of A and C. The medium orange backgrounds represent no effect (cf. calibration bars). Regions that on average are more or less responsive (lighter or darker tones) at the p < 0.05 level are tagged with a ‘*’. White stimuli appeared to generate peripheral suppression in response to attention. Yellow stimuli appeared to generate enhancement on average.
