Perception of mechanical contact or deformation through somatosensory receptors and processing. Discrimination depends on stimulus geometry, body site, exploratory action and task, not solely receptor density.

William G. Chase investigated how expertise changes perception and human memory. In experiments with Herbert A. Simon, chess players reconstructed briefly viewed positions and copied positions in view. Grouping and recall differed with skill and with the structure of the arrangement.^[ref]

The expert advantage was especially marked for meaningful chess positions. Random arrangements weakened the value of learned patterns, helping distinguish domain knowledge from a universal increase in immediate storage. The resulting chunking account explains how a player can retain relationships among pieces without encoding every piece as an unrelated item.
