Perceptual Exposure

Perceptual learning is learning better perception skills such as differentiating two musical tones from one another or categorizations of spatial and temporal patterns relevant to real-world expertise. Examples of this may include reading, seeing relations among chess pieces, and knowing whether or not an X-ray image shows a tumor... As our perceptual system adapts to the natural world, we become better at discriminating between different stimuli when they belong to different categories than when they belong to the same category. We also tend to become less sensitive to the differences between two instances of the same category.[17] These effects are described as the result of categorical perception. Categorical perception effects do not transfer across domains. https://en.wikipedia.org/wiki/Perceptual_learning cf Tacit Knowledge
