Abstract

This study examined the factors that determine performance on measures of sentence comprehension. The participants were 42 people with aphasia and 25 non-brain damaged controls. There were two measures of performance: accuracy data from each of 5 tasks (Object Manipulation and two versions each of sentence picture matching and grammaticality judgment) and reaction time data from 4 of the tasks (all but object manipulation). The results showed that a single factor accounted for most of the variance in the data. This result was observed both for accuracy and reaction time data, and in both groups of participants.
