“…For this reason, such hand and arm actions have variously been called "representational gestures" (McNeill, 1992), "illustrators" (Ekman & Friesen, 1969), "gesticulations" (Kendon, 2004), and "lexical gestures" (Krauss, Chen, & Gottesman, 2000). Consistent with the claim that speech-associated gestures convey information that complements the information conveyed in talk, speech-associated gestures have been found to improve listener comprehension, suggesting that they are meaningful to listeners (Alibali, Flevares, & GoldinMeadow, 1997;Berger & Popelka, 1971;Cassell, McNeill, & McCullough, 1999;Driskell & Radtke, 2003;Goldin-Meadow & Momeni Sandhofer, 1999;Goldin-Meadow, Wein, & Chang, 1992;Kendon, 1987;McNeill, Cassell, & McCullough, 1994;Records, 1994;Riseborough, 1981;Rogers, 1978;Singer & Goldin-Meadow, 2005;Thompson & Massaro, 1986). Speechassociated gestures are thus hand movements that provide accessible semantic information relevant to language comprehension.…”
