Letter recognition errors may be the result of children going through normal states of development. (Author)

Concludes that speed in identifying letters and graphonemes correlates highly with reading achievement. (RB)

Four experiments investigated the phenomenon of letter migration, the tendency of readers to assign letters from one word to another appearing in close proximity. The experiments, which involved college undergraduate students, revealed several properties of letter migration, including the following: (1) migrations are more frequent when the words…

G. Wolford's perturbation model of letter identification is designed to account for identification errors of briefly presented characters. Its chief assumptions are that features are extracted in parallel, that some of these features become perturbed or mislocalized, and that mislocalizations are more likely to occur in the direction of the fovea…

Reviews work on three areas of visual information that are available to readers: information provided by the conventional arrangements of the print on the page, by the features of each letter, and by the shapes of entire words. (HOD)

Fifteen college students read passages from a cathode-ray tube as their eye movements were monitored in a study that investigated the size of the visual region within which they used visual information to distinguish among letters as they read. (HOD)

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…

A study compared peripheral vision applied to letter-pair and Dolch word recognition. Subjects, 6 normal readers, 12 Chapter 1 students, and 34 learning disabled (and assumed dyslexic) students from grades one through three enrolled in a parochial school, a public school, and a university summer reading clinic, completed a test designed to…

This paper presents the results of investigations into mature readers' focal point when viewing letters, words, and phrases. The focal points are accurately determined by using the after image created from a spot of light. The after image is then superimposed on the reading material. The results show that the focal point does not fall haphazardly…

A study investigated the size of the perceptual span within which adults use visual information to distinguish among letters as they read. The eye movements of fifteen college students were monitored as they read passages from a cathode-ray tube. On occasional fixations, letters in specified visual regions were replaced by other letters. The…

Differences in perceptual processes of good and poor readers relevant to single word perception have been studied in a series of experiments. The major differences between good and poor readers have been shown to occur at the level of the single word; other differences occur in knowledge of spelling patterns and ability to make use of letters'…

Shows that native-speaking Arabic readers produce search functions that are radically different from the search functions of readers whose script uses the Roman alphabet (RAs). The processes used by Arabic readers are more akin to the processes used by RAs when searching arrays of shapes. (Author/LMO)
