A qualitative approach of learning in Parkinson's disease

Abstract

Verbal reports of PD patients and of two control groups (their matched Elderly and Young), obtained during the solving of the 4- disks Tower of Hanoi, were analyzed in terms of enunciative operations, cognitively interpreted. The analysis focuses on the processes involved in the reconstruction of implicit knowledge in a new context. Results show processes of deconstruction of implicit knowledge and several impairments in the processes involved in its reconstruction and stabilization. Notably, instead of locating objects relative to one another at the declarative level, PD patients locate objects, at the procedural level, by means of locating the place where they are or where they go, relative to one another. © 2010 Springer-Verlag.
