Three eye-tracking experiments investigated the role of pitch accents during online discourse comprehension. Participants faced a grid with ornaments, and followed pre-recorded instructions such as "Next, hang the blue ball" to decorate holiday trees. Experiment 1 demonstrated a processing advantage for felicitous as compared to infelicitous uses of L+H* on the adjective noun pair (e.g. blue ball followed by GREEN ball vs. green BALL). Experiment 2 confirmed that L+H* on a contrastive adjective led to 'anticipatory' fixations, and demonstrated a "garden path" effect for infelicitous L+H* in sequences with no discourse contrast (e.g. blue angel followed by GREEN ball resulted in erroneous fixations to the cell of angels). Experiment 3 examined listeners' sensitivity to coherence between pitch accents assigned to discourse markers such as 'And then,' and those assigned to the target object noun phrase.

语调的预期效果：指导视觉搜索期间的眼球运动

三项眼动追踪实验研究了音调口音在在线话语理解中的作用。参与者面对一个带有装饰品的网格，并按照预先录制的指令（例如“下一步，挂蓝球”）来装饰节日树。实验 1 证明了与 L+H* 在形容词名词对上的不恰当使用相比（例如，蓝色球后跟绿色球对绿色球）的处理优势。实验 2 证实对比形容词上的 L+H* 导致“预期”注视，并在没有话语对比的序列中证明了不恰当的 L+H* 的“花园路径”效应（例如，蓝色天使后跟绿色球导致错误对天使细胞的注视）。实验 3 检查了听众的
