Table 1 Subject information. Information for all subjects trained. Subjects are divided into those that trained with stimuli of the same size (unscaled), those that trained with stimuli which were scaled to match initial performance (scaled) and those that trained with crowded stimuli to match initial performance (crowded). M = male, F = female, OD = right eye, DS = dioptre sphere, Pl = plano, VA = visual acuity, LogMAR = logarithm of the minimum angle of resolution
