摘要:The Trace Deletion Hypothesis ofGrodzinsky (1990, 2000 and subsequent work) predicts that derived subjects present difficulties in interpretation for Broca9s aphasies. This prediction is borne out for passives in a number of languages, amongst which Spanish (Beretta et al. 1996). But the TDH in itself is not sufficient to account quantitively for the pattern of peri5rmance of agrammatic speakers (chance performance on the interpretation of actional passives); to account i5r it, Grodzinsky posits a Defiult Strategy. We investigate the predictions of the combined efect of the TDH and the Defeult Strategy for passives in Catalan,in a domain to our knowledge not previously investigated: that of agentive vs. non-agentive passives.
