Abstract

This multiple single case intervention study focusses on the production of non-canonical sentences with seven agrammatic participants. Cross-over training involved the production of object relative clauses, i.e. syntactically complex sentences and relying on higher nodes in the syntactic tree and object derived who-questions, i.e. less complex sentences and relying on lower nodes. The investigation evaluates individual structure specific effects, generalized effects for sentence structures of the same movement type and different movement type. Individual results, unambiguously attributable to the intervention are reported and discussed within two accounts of treatment of agrammatic sentence production, the Tree-Pruning-Hypotheses (TPH) and the Complexity-Account-Treatment-Efficacy (CATE).
