Abstract

This study evaluated one listening and three reading tasks with stimuli, scoring, and task requirements coherent for auditory and visual administrations of the Computerized Revised Token Test (CRTT), thus allowing for direct comparisons across modalities and language functions. Thirty Persons with Aphasia (PWA) and 30 Normal Elderly Individuals (NEI) received the four versions of the CRTT in random order. The Porch Index of Communicative Ability (PICA) and the Reading Comprehension Battery for Aphasia (RCBA) also were administered. In PWA the four versions were strongly related and highly correlated with the PICA and the RCBA. The NEI differed from this pattern.
