Abstract

The Revised Token Test (McNeil & Prescott, 1978, RTT) is a well-established test of auditory language processing disorders in persons with aphasia. A computerized version of the test, the Computerized Revised Token Test (C-RTT), was developed recently in our laboratory to better control stimuli presentation, and eliminate variability associated with the complex scoring requirements of the RTT. In the current study the impact of participant age and acoustic signal intensity on performance of non-brain injured adults on the C-RTT was assessed. Although age effects have not observed with the RTT, we believed that strict adherence to timing and stimuli characteristics allowed by computer administration and scoring could separate young from older adults.
