This study uses event-related brain potentials to investigate the difficulties that high math anxious individuals face when processing dramatically incorrect solutions to simple arithmetical problems. To this end, thirteen high math-anxious (HMA) and thirteen low math-anxious (LMA) individuals were presented with simple addition problems in a verification task. The proposed solution could be correct, incorrect but very close to the correct one (small-split), or dramatically incorrect (large-split). The two groups did not differ in mathematical ability or trait anxiety. We reproduced previous results for flawed scores suggesting HMA difficulties in processing large-split solutions. Moreover, large-split solutions elicited a late positive component (P600/P3b) which was more enhanced and delayed in the HMA group. Our study proposes that the pattern of flawed scores found by previous studies (and that we replicate) has to do with HMA individuals'difficulties in inhibiting an extended processing of irrelevant information (large-split solutions).
本研究使用事件相关脑电位来探究高数学焦虑个体在处理简单算术问题的明显错误解时所面临的困难。为此，13 名高数学焦虑（HMA）个体和 13 名低数学焦虑（LMA）个体在验证任务中接受了简单的加法问题。提出的解决方案可以是正确的、不正确但非常接近正确的（小分裂）或明显错误的（大分裂）。两组在数学能力或特质焦虑方面没有差异。我们重现了之前的研究结果，表明 HMA 在处理大分裂解时存在困难。此外，大分裂解诱发了一个晚期正成分（P600/P3b），在 HMA 组中更为增强和延迟。我们的研究表明，以前研究（包括我们的复现）中发现的有缺陷分数的模式与 HMA 个体难以抑制对无关信息（大分裂解）的扩展处理有关。
