Abstract

The study examined the role of conscious and unconscious processes depending on the level of arithmetic skill. The participants were divided into two groups according to their arithmetic skill based on the calculation fluency test results. Masked and unmasked single-digit addition problems (primes) followed by correct and incorrect results were presented on the screen. In a conscious perception task (unmasked priming), when large and small problem results were presented, an arithmetic N400 and LPC effects were observed in both groups. In the case of unconscious perception (masked priming), when small problem results were presented, the LPC effect was observed in the group with low arithmetic skill. The fact that the LPC arithmetic effect was discovered during the unconscious presentation may indicate the automatic nature of the encoding and retrieving information processes, reflecting neurophysiological characteristics associated with the level of arithmetic skill.

算术引物任务中的有意识和无意识过程取决于算术技能

摘要本研究探讨了有意识和无意识过程对算术水平的影响。根据计算流畅性测试的结果，被试按算术水平分为两组。在屏幕上显示屏蔽和未屏蔽的个位数加法问题（素数）以及正确和错误的结果。在有意识的感知任务（无掩蔽原语）中，当出现大问题和小问题结果时，两组都观察到了算术 N400 和 LPC 效应。而在无意识感知任务（遮蔽引物）中，当出现小问题结果时，算术能力低的一组中观察到了 LPC 效应。LPC算术效应是在无意识呈现过程中发现的，这一事实可能表明编码和检索信息过程的自动性质，反映了与算术技能水平相关的神经生理学特征。
