Does being instructed to gesture encourage those with low gesture rates to produce more gestures? If participants do gesture more when asked to, do they produce the same kinds of gestures? Does this vary as a function of the type of discourse being produced? We asked participants to take part in three tasks, a quasi-conversational task, a spatial problem solving task, and a narrative task, in two phases. In the first they received no instruction, and in the second they were asked to gesture. The instruction to gesture did not change gesture rate or gesture type across phases. We suggest that while explicitly asking participants to gesture may not always achieve higher gesture rates, it also does not negatively impact natural behavior.

人们在得到指示时会做更多手势吗？

被指示做手势是否会鼓励那些低手势率的人做出更多的手势？如果参与者在被要求时做更多的手势，他们是否会做出相同种类的手势？这是否会随着所产生的话语类型而变化？我们要求参与者分两个阶段参与三项任务，即准会话任务、空间问题解决任务和叙事任务。第一次他们没有收到任何指示，第二次他们被要求做手势。手势指令不会跨阶段改变手势速率或手势类型。我们建议，虽然明确要求参与者做手势可能并不总是能达到更高的手势率，但它也不会对自然行为产生负面影响。
