[Procedural learning in aphasic patients]

Abstract

Objective: This study concerned the procedural learning of semantic categorization.

Patients and methods: The procedure used was a serial reaction time in an group of aphasic patients.

Results: Group of aphasic patients performed slower reaction times with more errors than the controls, but everyone manifested a decreasing reaction time, even during new semantic material categorization.

Conclusions: Our results showed that the semantic categorization could be facilitated by procedural learning. Furthermore, this study suggest that procedural learning of semantic categorisation is at least relatively independent from cerebral structures usually involved a group of aphasic patients.
