谈话中的说话人转换通常很简短，声音重叠最小。签名语言似乎与这种模式背道而驰，频繁、长时间地同时签名。但最近的证据表明，手语中的话轮界限可能只包括话轮的内容承载部分(从第一笔到最后一笔)，而不是所有与话轮相关的动作(从第一次准备到最后一次收回)。我们测试了签名者是否能够在只有最少的对话语境的情况下预测“笔划对笔划”的转弯边界。我们发现，事实上，签名者预计转弯边界在转弯最后冲程的末端。签字人往往反应较早，特别是当转弯时间较长或包含多个可能的终点时。对于疑问句，长句的早期反应尤其明显--长句比短句表现出更多的预期。
Speaker transitions in conversation are often brief, with minimal vocal overlap. Signed languages appear to defy this pattern with frequent, long spans of simultaneous signing. But recent evidence suggests that turn boundaries in signed language may only include the content-bearing parts of the turn (from the first stroke to the last), and not all turn-related movement (from first preparation to final retraction). We tested whether signers were able to anticipate “stroke-to-stroke” turn boundaries with only minimal conversational context. We found that, indeed, signers anticipated turn boundaries at the ends of turnfinal strokes. Signers often responded early, especially when the turn was long or contained multiple possible end points. Early responses for long turns were especially apparent for interrogatives—long interrogative turns showed much greater anticipation compared to short ones.
