Orthographic regularity, positional frequency, and visual processing of letter strings: a reply to Krueger's comments.

Typing Letter Strings Varying in Orthographic

Subjects typed six-letter strings varying in orthographic structure. Lexical status, word frequency, position-sensitive log bigram frequency, and regularity of letter sequencing were systematically varied. Cumulative reaction times (RTs) of the keystrokes were adequately described by a linear function of letter position in the test string. Overall, words were typed faster than nonwords, and reg...

From orthography to phonetics: ERP measures of grapheme-to-phoneme conversion mechanisms in reading.

Neuroimaging has provided evidence that the first stages of visual word recognition activate a visual word-form center localized in the left extrastriate cortex (fusiform gyrus). Accordingly, neurological cases of patients suffering from pure alexia reported the left posterior occipital lobe as the possible locus of orthographic analysis. There is less agreement in the literature about which br...

Effect of orthographic processes on letter position encoding

We investigate whether orthographic processes influence the identification and encoding of letter position within letter strings. To minimise word-specific effects, we adopt a visual letter search task that requires participants to identify a cued letter target among a random five-letter string. Using this paradigm, previous studies have shown that letter targets to the left are identified fast...

Reading Ability and Utilization of Orthographic Structure in Reading

A perceptual-recognition task was used to assess whether utilization of orthographic structure in letter recognition varies with reading ability. Anagrams of words were made to create strings that orthogonally combined frequency and regularity measures of orthographic structure. These strings and the original words were used as test stimuli in a letter-recognition task. Good and poor college re...
