Previously, we (Hashemi et al., VSS 2015 & VSS 2016) investigated perceptual learning in a texture identification task using textures that contain diagnostic information (Target) in one orientation band and non-diagnostic information (Context) in a perpendicular orientation band. We found that, compared to Target-alone (ie, no Context) textures, training in a 1-of-6 identification task with Target+ Context textures resulted in lower accuracy, less learning, but greater generalization of learning. Specifically, training with Target+ Context patterns generalized to familiar Target-alone textures, but training with Target-alone stimuli did not generalize to familiar Target+ Context textures. Nevertheless, even with Target+ Context training, we found no evidence of generalization to novel targets, regardless of context. Here we investigated whether greater generalization of learning could be obtained by significantly increasing the …
