No evidence of relation between working memory and perception of interrupted speech in young adults

摘要

Understanding interrupted speech requires top-down linguistic and cognitive restoration mechanisms. To investigate the relation between working memory (WM) and perception of interrupted speech, 20 young adults were asked to recognize sentences interrupted at 2 Hz, 8 Hz, and a combination of 2 and 8 Hz. WM was measured using automated reading and operation span tasks. Interestingly, the results presented here revealed no statistical relation between any of the interrupted speech recognition scores and WM scores. This finding is in agreement with previous findings that suggest greater reliance on linguistic factors relative to cognitive factors during perception of interrupted speech.
