e/Perceptual learning

Information
has gloss	eng: The term perceptual learning refers to the process of long lasting improvement in performing perceptual (visual, auditory, tactile, olfactory or taste) tasks as a function of experience. Such tasks range from simple discriminations along a single dimension (e.g. orientation discrimination in the visual modality, frequency discrimination in the auditory modality) to complex categorizations, which typically involve the integration of several dimensions (e.g. an X-ray image, with or without a tumor). The ability to improve in such tasks is retained throughout life.
