Visual search with peripheral vision. (A) Task schematics: agent fixates one of the blue circle regions at any given time, the target (left-moving dots) is in one of the black circle regions. (B) Accuracy, (C) Search time and (D) number of switches for C-DAC and Infomax for two environments (c, β1, β₂, β₃, β₄) = (0.05, 0.62, 0.6, 0.55, 0.5), c_s = 0 and c_s = 0.005. C-DAC adjusts the time steps and number of switches depending on the environment, taking a little longer but reducing number of switches when effort has cost.
