Visual word recognition is facilitated by the presence of "orthographic neighbors" that mismatch the target word by a single letter substitution. However, researchers typically do not consider "where" neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate…

It is well-established that allographs like the uppercase and lowercase forms of the Roman alphabet (e.g., a and A) map onto the same "abstract letter identity," orthographic representations that are independent of the visual form. Consistent with this, in the allograph match task ("Are 'a' and 'A' the same letter?"), priming…

Does visuospatial orientation influence repetition and transposed character (TC) priming effects in logographic scripts? According to perceptual learning accounts, the nature of orthographic (form) priming effects should be influenced by text orientation (Dehaene, Cohen, Sigman, & Vinckier, 2005; Grainger & Holcomb, 2009). In contrast,…

Printed words that have a transposed-letter (TL) neighbor (e.g., angel has the TL neighbor angle) have been shown to be more difficult to process, in a range of paradigms, than words that do not have a TL neighbor. However, eye movement evidence suggests that this processing difficulty may occur on only a subset of trials. To investigate this…

The studies reported here examined the role of orthographic regularity and summed positional frequency in the perception of letter strings. College sophomores and sixth graders were asked to indicate whether or not a target letter was present in a six-letter string. Orthographic regularity and summed positional frequency were found to have no…

Nonwords created by transposing two "adjacent" letters (i.e., transposed-letter (TL) nonwords like "jugde") are very effective at activating the lexical representation of their base words. This fact poses problems for most computational models of word recognition (e.g., the interactive-activation model and its extensions), which assume that exact…

Alphabetic orthographies vary in the (in)consistency of the relations between spelling and sound patterns. In transparent orthographies, like Italian, the pronunciation can be predicted from the spelling, in contrast to opaque orthographies such as English, where spelling-sound correspondences are often inconsistent. The pronunciation of English…
