This experiment was designed to determine whether children's inability to discriminate mirror-image oblique lines is a function of encoding in memory the left-right orientation or the degree of slope of an oblique line. (Author/SB)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

To test the tendency of subjects to perceptually organize discrete temporal patterns with regard to runs of identical stimulus events, spatiotemporal patterns of white noise were presented for reproduction. It is suggested that changes in runs of auditory patterns are perceptually analogous to changes in contours of visual patterns. (Editor/RK)

Perceptual decentering was examined in 30 nonretarded children, 30 educable mentally retarded (EMR) children equated for CA, and 30 EMR children equated for MA. (Author)

A total of 180 6-, 8-, and 10-year-old children participated in tasks employing an object array in which the views from the experimental positions were objectively of equal difficulty. (SB)

Two approaches to auditory training for improved speech recognition using 20 adults with mild to moderate sensorineural hearing impairments were compared. No significant differences were found between group one which spent training time on activities involving sentence perception and perceptual strategy and group two which focused on consonant…

Outlines research findings on enriched environment investigations on the development of the brain's neocortex. Although the research has been conducted on animal brains, researchers expect to find related patterns in plasticity in humans. The research is important to educators as it challenges them to define, create, and maintain an emotionally…

Results of the study with 24 mildly or moderately retarded subjects (ages 11-55 years) indicates that a separability hypothesis of perceptual development can be extended to retarded populations. Representation as wholistic objects dominated among moderately retarded subjects, and with increasing intelligence, representation of objects as component…

The effects of remediation of hypothesized component deficits prior to remediation of known academic deficiencies were compared with remediation of academic (reading) deficiencies alone among 76 elementary grade learning disabled students. Results indicated better achievement for students receiving both remedial treatments. (Author/DB)

Four experiments studied the perception of the unity and boundaries of objects by 88 4-month-old infants who manipulated them out of the visual field. Infants perceived the unity/boundaries of these objects by detecting the motion patterns they themselves produced. Discrimination between motion patterns transferred from touch to vision. (SLD)

Evaluates models of infant visual preferences with predictions based on the physical attributes of visual patterns using pairs of schematic faces and abstract patterns identical except for contrast reversals. Results suggest that a fundamental change in the determinants of visual preference occurs postnatally between 6 and 12 weeks. (Author/RWB)

A series of six experiments compares young children's competence in attributing absence of knowledge (ignorance) to their competence in attributing a false belief to the other. (HOD)

Examines developmental change in 4- 7- and 10-month-old infants' perceptions of correlations among attributes to determine whether relational information plays a role in abilities ranging from the perception and recognition of a simple pattern to the formation of a category. (HOD)

Two variants of the habituation paradigm were used to investigate fine orientation discrimination and shape constancy in 34 young infants. Results demonstrate that conditions determine whether young infants show sensitivity to relatively fine variations in pattern orientation or give evidence of shape constancy with the same patterns. (HOD)

The position statement of the Council for Learning Disabilities' Board of Trustees opposes the measurement and training of perceptual and perceptual-motor functions as a part of learning disability services and recommends instead that assessment and remediation focus on the primary disorders of listening, speaking, reading, writing, reasoning, and…
