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…

Research suggests that when subjects are given a rule as to how to translate auditory or verbal information into images, the images have many common characteristics with cognitive representations derived from visual perceptions. This experiment examined the process of cognitive integration and the similarities and differences between how imagined…

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…

A previous study by Gibson et al. (1972) that investigated the effect of orthographic structure on letter search was replicated and extended in order to identify factors that might explain the apparent discrepancy between their results and those of comparable studies. Experiment one tested whether the discrepancy might be explained by difference…

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…

The reversal errors in the printing of 51 first grade students were examined. These children were asked to print a series of reversible target figures (letters and numbers, such as 2-s, p-q, p-9, and b-d) that were presented alone and with their mirror-image counterparts. To control for the possibility that the mere presence of another figure…
