The present experiment supports the hypothesis that the letter is the basic perceptual unit in letter, nonword, and word identification. (Author)

In two experiments, a probe technique required subjects to respond when the digit 7 appeared in one of five-letter positions in words or nonwords, inserted at the onset and 500 msec after letter and word processing. The focus of attention given to a letter has a smaller spatial extent. (Author/CM)

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)

The duration and timing of the context is which letters occur is shown to influence the perceptibility of the target in experiments demonstrating that early on enhanced word presentations and pronounceable-pseudoword contexts increase letter perceptibility. The perceptibility of letters in strings sharing several or few letters with words is…

The literature dealing with the identification process in beginning reading is surveyed. The first major section presents a review of the basal, Language Experience Approach, Phonic Word Method, linguistic, and i/t/a programs. Questions are raised about the empirical investigation of the subject matter and the instructional procedures used in…

In this study, eight groups of kindergarten children were trained to discriminate position and order differences in verbal and nonverbal item sequences in the context of a matching task or an associative learning task or both. Transfer was measured by having the subjects sight learn a list of words contrasting in position and order. Subsequently,…
