In this paper three experimental techniques are described for studying ambiguous characters and for investigating the relationship between physical attributes and functional attributes. (Author)

Letter recognition errors may be the result of children going through normal states of development. (Author)

Children's visual perception of the letters b and d when confronted with them for the first time was studied. (KW)

Primary purpose of the present research was to test the reasoning that any procedure that interferes with the naming of the test stimuli, while leaving visual complexity unaffected, ought to increase the detrimental effects on reaction time and accuracy produced by changing case. (Authors/CB)

Results of three experiments are reported, which indicate that images of simple two-dimensional patterns are formed sequentially. The subjects included 48 undergraduates and 16 members of the Harvard University (Cambridge, Mass.) community. A new objective methodology indicates that images of complex letters require more time to generate. (TJH)

In three experiments, this study addressed two basic questions about the detection of multiletter patterns: (1) How is the detection of a multiletter pattern related to the detection of its individual components? (2) How is the detection of a sequence of letters influenced by the observer's familiarity with that sequence? (Author/BW)

The primary concern in this study has been to interpret the ways in which perception of a letter depends on properties of other letters present in the same display. (Author)

Although a feature detection theory of pattern recognition is consistent with many recent physiological findings, the specific rules governing the perception of the distinctive features of letters have not yet been determined. This article presents two new experimental procedures for determining these rules. (Editor)

Concludes that speed in identifying letters and graphonemes correlates highly with reading achievement. (RB)

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…

This paper reports some experimental evidence on the viability of the preliminary letter recognition hypothesis. (Author)

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

Two experiments examined the perceptual processing of letters embedded within one- and two-syllable words and visually similar nonwords. Results suggest that (1) the size of compelling perceptual units seems limited, and (2) unit size is not necessarily related to the correspondence between letter order and pronounceability.
