An event-related brain potential study of receptive speech comprehension using a modified Token Test

There is a long and distinguished history of evaluating sensory functions with evoked potentials (EPs). However, the clinical utility of event-related brain potentials (ERPs) in the assessment of cognitive functions remains to be established. We present evidence for the efficacy of ERPs in the assessment of speech comprehension. In this normative study, a version of the Token Test (Boller and Vignolo, 1966, Brain, 89, 815-831: De Renzi and …
