Abstract

Short-term memory (STM) effects have shown to be distinguishable from other working memory components supporting complex computations/central executive functions. To develop a measure capable of assessing the effects of STM and linguistic computations on sentence processing,  effects of syntactic complexity and padding were investigated with the Computerized Revised Token Test –Revised in individuals with aphasia and control participants.  Off-line measures revealed clear effects of both factors.  The expected interaction of complexity and padding  and overadditive effects for individuals with aphasia were not found. An effect of complexity on word errors in passive sentences for individuals was shown.
