The proportions of target signs produced in response to noun- and verb-target vignettes that were placed in utterance-final position, or produced with proximal joint movement, repetition, or with a base hand by ASL signers. ASL signers were more likely to produce verb-target signs (black) in utterance-final position (first columns on the left, both top and bottom), with large movements of the proximal joints (second columns), and without repetition (third columns). Each of these three patterns was true for both iterable (top) and noniterable (bottom) events. ASL signers made little use of the base-hand function of the nondominant hand (fourth columns); none of the eighteen lexically one-handed target signs produced in response to target stimuli for noniterable events used a base hand (fourth columns, bottom).
