Abstract

Eighteen right-hemisphere-damaged (RHD) and 15 control subjects listened to sentences that ended in lexical ambiguities. The sentence verbs biased ambiguity interpretation. Probe words, representing unbiased meanings of the ambiguities, were presented for rapid judgements of their fit with the sentences. In rejecting probe words, both groups showed interference from unbiased meanings of the ambiguities at a short (175 ms) probe interval. Only RHD adults demonstrated interference 1000 ms after sentence offset, indicating that they suppressed contextually inappropriate meanings less effectively than control subjects. Discourse comprehension performance in RHD adults was also correlated with suppression. Theoretical and clinical implications are considered.
