The organization of the conceptual system: the case of the "object versus action" dimension.

abstract：:We report an experimental study of the factors that elicit manual interference in a patient with so-called "anarchic hand" behaviour in everyday life (Della Sala, Marchetti, & Spinnler, 1991, 1994) due to corticobasilar degeneration. The patient, ES, showed problems with both hands. We used tests in which ES had to re...
