“…This follows from the strong correlation between movement displacement and peak velocity that has been observed in both speech and non-speech movements (e.g., Cooke, 1980;Ostry et al 1983;Kelso et al, 1985;Vatikiotis-Bateson and Kelso, 1993;Hertrich and Ackermann, 1997;Löfqvist and Gracco, 1997). One exception to this pattern can occur when a movement of one articulator is truncated by a following gesture, so that its movement displacement is decreased (e.g., Munhall et al, 1992;Harrington et al, 1995;Byrd et al, 2000).…”
