Skilled readers have developed a certain amount of tolerance to variations in the visual form of words (e.g., CAPTCHAs, handwritten text, etc.). To examine how visual distortion affects the mapping from the visual input onto abstract word representations during normal reading, we focused on a single type of distortion: letter rotation.…

A commonly shared assumption in the field of visual-word recognition is that retinotopic representations are rapidly converted into abstract representations. Here we examine the role of visual form vs. abstract representations during the early stages of word processing--as measured by masked priming--in young children (3rd and 6th Graders) and…

The present study used two letter detection tasks, the classic missing letter effect paradigm and a single word versus familiar word compound version of this paradigm, to study bottom-up and top-down processes involved in reading in normally achieving as compared to low achieving elementary school readers. The research participants were children…

In the Jackson and Coltheart theory of acquisition of word reading it is claimed that, near the beginning of the partial alphabetic phase of development, children have full use of abstract letter units (ALUs). This claim and less exclusive alternatives were examined. In Experiment 1, normal progress children with on average 9 months of school…

The ability of 20-24 month-old toddlers to recognize graphemes and phonemes was investigated by reading a "Phonic Faces" (PF) alphabet picture book. Phonic Faces iconically picture a letter in the mouth of a character producing the sound (the curve of the P looks like the top lip popping the /p/ sound). The book was composed of nine…

We attempted to simulate the main features of letter-by-letter (LBL) dyslexia in normal readers through stimulus degradation (i.e. contrast reduction and removal of high spatial frequencies). The results showed the word length and the letter confusability effects characteristic of LBL dyslexia. However, the interaction of letter confusability and…

Research studies how visual information and redundancy contribute to letter and word identification. (Authors)

A review of (1) the Tutor-Student-System, (2) Initial Teaching Alphabet, (3) Words in Color, and (4) the Michigan Successive Discrimination Program (MSDP) is presented in this paper. (WR)

Reports on experiments designed to explore the way the processing unit depends on the information in the component letters and the information contained in their arrangements in a familiar letter string. Hypotheses were tested by degrading the quality of individual letters and by spacing the letters irregularly. (CLK)

This study investigated alternate methods of letter discrimination pretraining and word recognition training in young children. Seventy kindergarten children were trained to recognize eight printed words in a vocabulary list by a mixed-list paired-associate method. Four of the stimulus words had visual response choices (pictures) and four had…

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…

In this study, the author elucidated whether reading experience continues to contribute to word recognition skills in readers with well-internalized reading skills. The participants performed consecutive same or different judgments regarding the identicalness of letters, words, and pseudohomophones. For a more detailed examination of how increased…

The purpose of this study was to investigate to what extent the knowledge of letter names, letter sounds, or the combination of both facilitates the acquisition of word recognition ability. Forty-eight first graders were pretested and posttested on their knowledge of letter names and sounds, and measures of auditory and visual discrimination…
