To learn to read, the brain must repurpose neural systems for oral language and visual processing to mediate written language. We begin with a description of computational models for how alphabetic written language is processed. Next, we explain the roles of a dorsal sublexical system in the brain that relates print and speech, a ventral lexical…

A study of the constraints on word recognition errors (miscues) readers make when reading a passage printed conventionally and one printed in a regularized orthography such as the initial teaching alphabet (i.t.a.) was undertaken with 50 second-grade students divided equally between children taught according to the orthographies being studied. The…

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…

Fourteen college students read passages displayed on a cathode-ray tube as their eye movements were monitored in a study that examined (1) whether letters that lie in the center of vision are used earlier in the fixation than letters further to the right, (2) how soon after a stimulus event that event can affect eye movement control, and (3) how…

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)

Three experiments examine the information extraction process in adults and elementary school children reading paragraphs or words. In experiments 1 and 2 subjects were presented paragraphs to read and to search for specified targets. In experiment 3 subjects were asked to judge whether briefly presented pairs of letters were the same or different.…

Presents contrasting evidence on the rate of letter identification. (AEA)

A study assessed the role of orthographic structure in college students' perceptual recognition and judgment of letter strings. Lexical status, word frequency, bigram frequency, log bigram frequency, and regularity of letter sequencing were orthogonally varied across a series of experiments. Six-letter words and their anagrams were used as test…

The hypothesis that word context reduces visual rather than acoustic confusion between possible targets was tested in a series of experiments. All involved tachistoscopic presentation of letter strings followed by a pattern mask. Data from eight college students showed that target letters that are confusable only visually and acoustically…

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'…

As part of a two-year project that examined the processes by which children initially approach the reading task, a study was devised to test the project's materials and procedures. Selected by a pretest, four kindergarten children, with no prior reading instruction, were taught the same reading content using the initial teaching alphabet for a…

As part of a two-year project that examined the processes by which children initially approach the reading task, the second phase of a preliminary study was devised that modified the pretest, the instructional modes and format, the sequence and amount of information presented in the instructional sessions, and the procedures for testing and…

Summarizing the final phase of a two-year project that examined the processes by which children initially approach the reading task, this report presents both general and individual findings derived from the analyses of the children's performance over the course of a year. The first section discusses the following general topics related to the…
