A: Mean performance functions for all subjects by texture type, presented separately according to subject and texture size. For All16 (16x16 textures) and All32 (32x32) error bars are SE for n = 6 subjects. Glider shapes are shown in the bottom panel. B: Communalities for 5 different factor models. As the number of factors grows, the profile of bars becomes flatter indicating that the models progressively account for the data in a more balanced way. After nf = 3, the improvement in the reconstruction is marginal.
