First grade students (n=221) were tested on measures of verbal fluency, visual attention, phonological awareness, orthographic recognition, rapid automated naming (RAN) of letters and objects, and reading. Findings indicated that word reading was directly and significantly predicted by RAN letter naming and general RAN cognitive processing time of…

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…

This study, involving 47 students in grades 2-10, investigated letter-naming speed to determine whether it measures cognitive speed, a theoretical factor that purportedly influences reading rate. It was determined that cognitive speed and cognitive power are two independent factors and that letter-naming speed can be used to measure cognitive…

Reports results of four experiments testing whether syllable structure affects children's performance in phonemic analysis tasks and in other reading related tasks. The experiments were motivated by theories that syllables consist of an onset (initial consonant or consonant cluster) and a rime (vowel and any following consonants). (AS/Author)

Two criteria for the automatic encoding of learning, instructional manipulation, and stimulus characteristics were studied in subjects who judged the frequency of occurrence of words, letters, and nonwords. In Experiment 1, six word lists were constructed with varying frequency of alphabet letters. A variety of instructions were presented (whether…
