A laboratory and a classroom study were conducted to determine if verbal association learning would be facilitated by visual discrimination training. Kindergarten children who could not recognize the letters used were the subjects for both studies. In the laboratory study, 90 subjects were randomly assigned to the experimental group (E) which got…

A study of eighty Canadian kindergarten children showed that discrimination of similar letters was more difficult than distinctive letter discrimination, irrespective of training format or mode of testing. (MJB)

Reports a study in which the letters F, G, and K were presented in normal and backward versions, in varying angular orientations, in left and right visual fields. (Author/NH)

Small graphic changes made in normal letters of the alphabet changed the similarity relations among those letters. Children and adults classified letters of this distinctive font faster and with fewer errors than they did normal letters. Relations between letters in the stimulus set determined how difficult any particular letter was to classify.…

A REVIEW OF THE LITERATURE CONCERNING THE RELATIONSHIP BETWEEN MEASURE OF PREREADING VISUAL DISCRIMINATION AND FIRST-GRADE READING ACHIEVEMENT IS GIVEN. THE RELATIVE PREDICTIVE POWER OF VISUAL DISCRIMINATION OF LETTERS, WORDS, GEOMETRIC DESIGNS, AND PICTURES WHEN THESE ABILITIES ARE STUDIED INDIVIDUALLY AND IN COMBINATION IS INDICATED. STUDIES…

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.

The stimulus properties of the letters b, d, p, and q were investigated in an attempt to demonstrate that the common reversal of these letters by beginning readers is in part determined by the vertical aspect of the stimulus figure. One hundred eighty kindergarteners were randomly selected from a racially mixed population and randomly assigned to…

The purpose of this investigation was to study the effect of controlling the letters used in words both for a training program designed to improve visual discrimination and for a word recognition task. The experiment was designed to investigate the influence of simultaneous and successive discrimination learning with stimuli which varied in…

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

Effects of target-noise similarity on the ability to discriminate between two target letters were investigated. Performance was low when the noise letter shared the same name as the target. Thus, interletter interference effects cannot be explained in terms of inhibition between visual features. A "cognitive masking" hypothesis is proposed.…

Comparing the effectiveness of four methods for training young children (4-4.5 years) in the skills of visual discrimination necessary to letter knowledge acquisition, this study indicates that training in oral description of critical cues of letters contributes to superior achievement in learning to match letters.
