本研究通过两个实验考察了正常人在线段平分（LB）错误中所表现出的伪对称性以及LB与知觉不对称性之间的关系。在第一项研究中，63名右撇子和48名左撇子的参与者明显向左横切线条，左撇子的偏见比右撇子的偏见更强。还存在半空间效应。嵌合的脸，点填充的矩形，并比较穆勒-莱尔错觉线箭头的感知不对称与LB分数没有相关性。在第二项研究中，24名右撇子参与者在纸笔版的LB中出现了二等分错误，但在计算机版的LB中没有，尽管分数是相关的。prebisected线的平均感知是无偏的，这和LB任务之间的相关性低于纸和铅笔和计算机LB任务之间的相关性。这些发现表明，一些非知觉，可能是运动，因素有助于LB偏见。
Two experiments were conducted to examine pseudoneglect as reflected in line bisection (LB) errors made by normal individuals and the relationship between LB and perceptual asymmetries. In Study 1, 63 dextral and 48 sinistral participants transected lines significantly to the left, and sinistrals' biases were stronger than dextrals' biases. Hemispatial effects were also present. Perceptual asymmetries for chimeric faces, dot-filled rectangles, and comparisons of Muller-Lyer illusion lines to arrows did not correlate with LB scores. In Study 2, 24 dextral participants had leftward bisection errors for a paper-and-pencil version of LB but not a computer version, although scores were correlated. Average perception of prebisected lines was unbiased, and correlations between this and LB tasks were lower than correlations between paper-and-pencil and computer LB tasks. These findings suggest that some nonperceptual, and possibly motor, factor contributes to the LB bias.
