Perceptual learning accounts of orthographic coding predict that transposed-letter (TL) priming effects should be smaller when the prime and target stimuli are not presented in their canonical (left-to-right horizontal in English) orientation (Dehaene, Cohen, Sigman, & Vinckier, 2005; Grainger & Holcomb, 2009). In contrast, abstract letter unit accounts would propose that TL priming effects should be essentially unaffected by presenting stimuli in most unfamiliar text orientations (Witzel, Qiao, & Forster, 2011). In the present experiments, we examined masked TL priming effects with primes and targets presented in 3 different text orientations (e.g., 0°, as well as 90° and 180° rotations). Results revealed that the magnitude of the TL priming effect with native English readers was equivalent for stimuli presented in these three orientations, providing support for abstract letter unit accounts of orthographic coding.

知觉学习理论对正字法编码的解释预测，当启动刺激和目标刺激不以其典型的（英文从左到右的水平）方向呈现时，转置字母（TL）启动效应应该更小（Dehaene、Cohen、Sigman 和 Vinckier，2005；Grainger 和 Holcomb，2009）。相比之下，抽象字母单元理论则认为，当以大多数不熟悉的文本方向呈现刺激时，TL 启动效应应该基本不受影响（Witzel、Qiao 和 Forster，2011）。在本实验中，我们用 3 种不同的文本方向（例如，0°，以及 90°和 180°旋转）呈现启动刺激和目标刺激，检查了掩蔽 TL 启动效应。结果表明，以英语为母语的读者的 TL 启动效应的大小在这三种方向上是相等的，这为正字法编码的抽象字母单元理论提供了支持。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
