在日常生活中，在口语数字和阿拉伯数字之间无缝切换是很常见的。在本研究中，我们系统地研究了成人听觉数字词与视觉阿拉伯数字之间的对应关系。听觉数字词和视觉阿拉伯数字是同时或顺序呈现的，参与者必须指出他们描述的数量是否相同。我们操纵了两个刺激(实验1：-500毫秒至+500毫秒；实验2：-200毫秒至+200毫秒)之间的刺激起始异步值(SA)。在这两个实验中，我们都发现了显著的跨通道距离效应。这一效应在同时呈现刺激时最强，并随着SOA的增加而减弱。数字距离总体上成为最一致的显著预测因子，特别是对于同时呈现的情况。然而，除了数字距离外，刺激之间的物理相似性通常是反应时间的显著预测因素，而在较长的SOA中，刺激之间的物理相似性是唯一显著的预测因素。这表明，SOA调整了参与者访问数量表示的程度。因此，我们的结果支持这样的观点，即当被试执行并行匹配任务时，听觉和视觉数字符号的语义量表征被激活，而在更长的时间内，被试更可能依赖于刺激之间的物理相似性。我们还调查了跨通道加工效率的个体差异是否与数学成绩的差异有关。我们的结果并不能确定跨格式数字对应的效率是否与成人的数学能力有关。
Moving seamlessly between spoken number words and Arabic digits is common in everyday life. In this study, we systematically investigated the correspondence between auditory number words and visual Arabic digits in adults. Auditory number words and visual Arabic digits were presented concurrently or sequentially and participants had to indicate whether they described the same quantity. We manipulated the stimulus onset asynchronies (SOAs) between the two stimuli (Experiment 1: -500 ms to +500 ms; Experiment 2: -200 ms to +200 ms). In both experiments, we found a significant cross-modal distance effect. This effect was strongest for simultaneous stimulus presentation and decreased with increasing SOAs. Numerical distance emerged as the most consistent significant predictor overall, in particular for simultaneous presentation. However, physical similarity between the stimuli was often a significant predictor of response times in addition to numerical distance, and at longer SOAs, physical similarity between the stimuli was the only significant predictor. This shows that SOA modulates the extent to which participants access quantity representations. Our results thus support the idea that a semantic quantity representation of auditory and visual numerical symbols is activated when participants perform a concurrent matching task, while at longer SOAs participants are more likely to rely on physical similarity between the stimuli. We also investigated whether individual differences in the efficiency of the cross-modal processing were related to differences in mathematical performance. Our results are inconclusive about whether the efficiency of cross-format numerical correspondence is related to mathematical competence in adults.
