    "abstract": "Multi-modal discourse comprehension requires speakers to\ncombine information from speech and gestures. To date, little\nresearch has addressed the cognitive resources that underlie\nthese processes. Here we used a dual task paradigm to test the\nrelative importance of verbal and visuo-spatial working\nmemory in speech-gesture comprehension. Healthy, collegeaged\nparticipants encoded either a series of digits (verbal\nload) or a series of dot locations in a grid (visuo-spatial load),\nand rehearsed them (secondary memory task) as they\nperformed a (primary) discourse comprehension task. The\nlatter involved watching a video of a man describing\nhousehold objects, viewing a picture probe, and judging\nwhether or not the picture was related to the video. Following\nthe discourse comprehension task, participants recalled either\nthe verbally or visuo-spatially encoded information.\nRegardless of the secondary task, performance on the\ndiscourse comprehension task was better when the speaker’s\ngestures were congruent with his speech than when they were\nincongruent. However, the congruency advantage was smaller\nwhen the concurrent memory task involved a visuo-spatial\nload than when it involved a verbal load. Results suggest that\ntaxing the visuo-spatial working memory system reduced\nparticipants’ ability to benefit from the information in\ncongruent iconic gestures.",
