Word frequency, but not word length, consistently predicts lexical retrieval in healthy individuals and in aphasia. Word-retrieval di伍culties accompanying aphasia are typically measured via confrontation naming and cloze tests，but rarely in discourse. Measuring retrieval di伍culty during connected-speech production is challenging，especially when the target word is not pre-determined We examined the e伍ciency of word-retrievai in sentence context by measuring latencies of pre-noun pauses, asking whether word-length and frequency contribute to pre-retrieval pauses in mild nonfluent aphasia.
