Errors in discriminating right from left, termed right-left confusion, reflect a failure in translating visuospatial perceptions into verbal representation of right or left (i.e., visuo-verbal process). There may also be verbo-visual process, where verbal cues are translated into visual representations of space. To quantify these two processes underlying right-left confusion, Study 1 investigated the factor structure of the Right-Left Confusability Scale, which assesses daily experiences of right-left confusion. Exploratory factor analysis suggested that these two processes and another factor reflecting mental rotation underlie right-left confusion. Study 2 examined correlations between the (sub)scale scores and performance on orientation judgment tasks reflecting visuo-verbal and verbo-visual processes. Overall, self-reported measures were not associated with the behavioral performances presumably reflecting the two processes. These results suggest that the cognitive mechanisms underlying right-left confusion can be classified into visuo-verbal and verbo-visual processes and mental rotation, although their psychometric and behavioral indices might be distinct. Further studies may develop better assessments of right-left confusion reflecting these processes.
区分左右时出现的错误，即左右混淆，反映了将视觉空间感知转化为左右的语言表征（即视觉-语言过程）的失败。也可能存在语言-视觉过程，即语言线索被转化为空间的视觉表征。为了量化左右混淆背后的这两个过程，研究1调查了左右混淆量表的因子结构，该量表评估左右混淆的日常体验。探索性因子分析表明，这两个过程以及另一个反映心理旋转的因子是左右混淆的基础。研究2检验了（子）量表得分与反映视觉-语言和语言-视觉过程的方向判断任务表现之间的相关性。总体而言，自我报告的测量与可能反映这两个过程的行为表现无关。这些结果表明，左右混淆背后的认知机制可分为视觉-语言和语言-视觉过程以及心理旋转，尽管它们的心理测量和行为指标可能不同。进一步的研究可能会开发出更好的反映这些过程的左右混淆评估方法。
