Abstract

Verbal Working Memory (VWM) specifies the fundamental cognitive components (language computations (LC), short term memory, executive attention (EA)) for sentence comprehension.  Tests for VWM do not assess their differential impairments.  The Computerized Revised Token Test (Reading) (CRTT-R) was administered in normal reading and “Stroop” conditions to controls and persons with aphasia (PWA).  CRTT-R captured the LC and EA components of VWM in both groups.  On-line color word reading times and errors captured the EA effects.  Off-line CRTT-R scores, reading and response times captured the LC effects.  Response time yielded the expected PWA by EA and PWA by LC complexity interactions.
