| summary | Case studies in Hebrew and Arabic showed that tense inflection was harder than
agreement inflection for agrammatic patients in oral production (Friedmann &
Grodzinsky 1997; Friedmann 2001; Tissen et al. 2007). Recent studies revealed that
this dissociation was found in both oral production and grammaticality judgment in
various languages, including German (Wenzlaff & Clahsen 2004), Greek (Varlokosta
et al. 2006), Moroccan Arabic (Diouny 2007), Dutch (Kok et al. 2007), and English
(Clahsen & Ali 2009). We report results from an Arabic-speaking fluent aphasic whose
performance on sentence completion (oral production) and grammaticality judgment
tasks displays impairment with verbal inflections. We found that the patient was
significantly more impaired in tense/aspect than agreement in production, with the
opposite pattern in grammaticality judgment. This double dissociation supports our
proposal that tense and agreement can be independently impaired, not only across
agrammatic patients (Burchert et al. 2005), but also across tasks/modalities within a
single patient. Our results pose a serious challenge to Friedmann & Grodzinsky’s
(1997) and Lee’s (2003) purely representational/structural ‘Tree-Pruning’ accounts of
Tense/Agreement dissociation in agrammatism, and to both Wenzlaff & Clahsen’s
(2004) and Burchert et al.’s (2005) Underspecification accounts. |
