Dissociação entre movimento de xp e de x0: sem evidências do agramatismo

Abstract

This paper is intended to show that a proposal (Grodzinsky & Friederici 2006) on dissociation between two types of movement (MOVE XP and MOVE V ) is not supported by a critical review of data found in the literature of studies dealing with agrammatic aphasia. This procedure is considered to be of fundamental relevance for studies that plan to use evidence derived from studies based on linguistic aphasiology, since this field exhibits some problematic aspects concerning data analysis. Some conclusions reviewed here, thought to be straightforward, are, indeed, subject to questioning. In other cases, there are contradictory results that are commonly ignored in the construction of hypotheses. It is offered, then, a new posture on the consideration of the validity of studies that focus on aphasic syndromes within a linguistic framework.
