From: Peripheral vision and pattern recognition: A review Journal of Vision. 2011;11(5):13. doi:10.1167/11.5.13 Figure Legend: Internal representations of pattern categories acquired in direct (centre column) and indirect view (left and right column) by two subjects (AD and KR) in a three-class learning paradigm involving a set of 15 compound Gabor patterns. The corners of the dotted triangles represent the class means of the pattern categories within the generating evenness/oddness Fourier feature space. Internalized class prototypes (open and closed symbols) were obtained by fitting the PVP model to the psychophysical classification matrix cumulated across the learning sequence of each observer. Learning duration, as indicated by the number of learning units to criterion (numbers at the triangle tip), increases nearly ten-fold in indirect view (from Jüttner & Rentschler, 1996).
