To examine whether enantiomorphy (i.e., the ability to discriminate lateral mirror images) is influenced by the acquisition of a written system that incorporates mirrored letters (e.g., b and d), unschooled illiterate adults were compared with people reading the Latin alphabet, namely, both schooled literate adults and unschooled adults…

Two studies were conducted to evaluate the extent to which visual discrimination (VisD) skills play a role in developing letter identification abilities, which are essential in learning to read. Results from a correlational analysis of 73 4- and 5-year-olds revealed a significant association between VisD and letter identification abilities, which…

Describes a study of the visual discrimination abilities of children who varied in their ability to recognize words. Indicates that visual discrimination skills of the type needed to discriminate between single artificial graphemes do not seem essential for the word recognition aspect of reading. (TJ)

Reviews selected instructional procedures in the four reading readiness skills that can be taught and learned: auditory discrimination, auditory comprehension, visual discrimination, and visual memory. Stresses that readiness skills are prerequisite to reading skills. (RS)

This study examined the discriminability of lexigrams versus printed words with eight adults with severe mental retardation. A match-to-sample teaching paradigm was used. Subjects discriminated lexigrams better than printed letters and were more successful at matching lexigrams to referent objects than matching printed words to referent objects.…

Forty kindergarten children were randomly assigned to four conditions to investigate the influence of criterion level on the discrimination of highly confusable letters in beginning reading. Half the subjects were exposed to simultaneous, and half to successive discriminations. The groups were equally divided as to criterion level, i.e., four vs.…

In two experiments, a short-term recognition memory task that varied the number of letters distinguishing target and comparison stimuli was used to assess the ability of prereaders and beginning readers to utilize graphic information in a three-letter graphic pattern. (HOD)
