Assessment of explicit and implicit linguistic impairments in patients with aphasia after resection of tumour of the left cerebral hemisphere. Preliminary results.

Background And Purpose: Classical definitions of aphasia des-cribe deficits of different language levels (syntactic, semantic, phonologic) hindering the ability to communicate. Recent studies indicate, however, that impairment of particular aspects of linguistic competencies in aphasia differs in severity. Contemporary approach to the aphasic symptoms presents them as disturbed access of linguistic representations to the awareness system.
