Abstract

Responses of forty-two patients with aphasia secondary to left hemisphere strokes to eleven sentence types in enactment and sentence-picture matching tasks were modeled using Rasch models that varied in the inclusion of the factors of task, sentence type grouping, and patient clustering. The best fitting models required the factors of task and patient group but not sentence type grouping. The simulation suggests that aphasic syntactic comprehension is best accounted for by models that include different estimates of resource availability for different tasks and different resource availability in different groups of patients, but not deficits affecting specific syntactic structures.
