算术表达，就像动词句子一样，逐渐引导读者预测潜在的适当补全。语言领域的现有工作帮助我们了解了两个大脑半球如何不同地参与和贡献句子阅读的认知过程，但在数学公式处理方面的工作相对较少。在这项研究中，我们通过考察对简单乘法问题提供的答案的事件相关电位反应来解决这一差距，这些问题在正确率水平(给定等式上下文)和呈现的视野(中央呈现的联合注意，或通过对侧视野呈现向左或右半球的偏向加工)上都有所不同。当给出任何视野(半球)的答案时，在传统的N400时间窗之前有一种正确性的效果，我们将其解释为对检测到的目标项(正确答案)做出反应的P300。除这一反应外，等式答案还引发了错误答案的迟发积极复合体(LPC)。值得注意的是，这种LPC效应在左侧视野(右半球)最为突出，而且它对错误答案的易混性也很敏感--与正确答案密切相关的错误答案会引起较小的LPC。这表明右脑在答案评估过程中扮演着特殊而持久的角色。
Arithmetic expressions, like verbal sentences, incrementally lead readers to anticipate potential appropriate completions. Existing work in the language domain has helped us understand how the two hemispheres differently participate in and contribute to the cognitive process of sentence reading, but comparatively little work has been done with mathematical equation processing. In this study, we address this gap by examining the ERP response to provided answers to simple multiplication problems, which varied both in levels of correctness (given an equation context) and in visual field of presentation (joint attention in central presentation, or biased processing to the left or right hemisphere through contralateral visual field presentation). When answers were presented to any of the visual fields (hemispheres), there was an effect of correctness prior to the traditional N400 timewindow, which we interpret as a P300 in response to a detected target item (the correct answer). In addition to this response, equation answers also elicited a late positive complex (LPC) for incorrect answers. Notably, this LPC effect was most prominent in the left visual field (right hemisphere), and it was also sensitive to the confusability of the wrong answer – incorrect answers that were closely related to the correct answer elicited a smaller LPC. This suggests a special, prolonged role for the right hemisphere during answer evaluation.
