Experiment conducted to determine the different effects of a mediational method of verbal learning and visual-discrimination verbal learning. (Author/MM)

Suggests methods and materials for improving the perception abilities of young children. (NH)

Fourteen severely multiply handicapped children with rubella syndrome, six to 16 years of age, were examined with the PLAYTEST system, an operant test procedure using sound and light as stimuli and reinforcers. (Author/MC)

Eighty-two educable and trainable mentally retarded children (6-18 years old) judged whether a series of visual stimuli matched a standard. With each judgment the investigator verbalized "right" or "wrong" and then provided full feedback of cue similarities and differences that supported each judgment. Trained Ss exhibited total intradimensional…

Six diagnostic tasks of two choice discrimination skills were used to assess 32 hearing impaired/mentally handicapped adults residing in a state institution. Two tasks measured sign discrimination skill, two measured visual discrimination, and two measured motor discrimination. (Author)

Reports effects of context that are entirely perceptual. Visual discrimination was enhanced when line segments were flashed in a region that was perceived as a figure. Discrimination was substantially degraded when the same region was seen as ground although the physical stimulus remained identical throughout figure-ground reversals. (Author/JN)

Presents computational and psychophysical evidence in support of a theory of one of the earliest stages of visual processing in reading--the isolation of words in text. (HOD)

Investigated three-month-olds' abilities to discriminate and recognize smiling and frowning expressions of mothers and strangers. Discrimination and recognition occurred regardless of the adult who was involved; however, more infants discriminated the mothers' expressions than the strangers', and boys looked at their mothers' faces longer than did…

Explored the relationship among conceptual tempo, age, sex, and performance of preschool children on the visual association subtest of the Illinois Test of Psycholinguistic Abilities. (Author/DB)

High state-anxious subjects solved fewer problems than middle or low state-anxious subjects under no memory-aid conditions, and all anxiety groups performed comparably with memory aids. High state-anxious subjects tended to use less focusing strategy when memory aids were unavailable. (Author/CP)

Discusses research regarding the development of infants' smiling at, gazing at, and interest in faces. (Author/DB)

Investigated ability of young children to interpret aerial photographs and maps, sought age and/or cognitive development differences, and probed whether or not some environmental features were more consistently recognized than others. (Author/DB)
