Problem studied: How children represent haptic spatial information in memory. Question aimed at: Whether, and if so in what ways, children's spatial representations differ according to the main modality of prior experience. (JH)

Non-verbal recall of haptically presented spatial positions by three age groups of blind and sighted children was tested under conditions varying cuing, recall type and stimulus position in a within-subject design. (Editor)

Forty-eight blind children, able to cope with set sizes of two and three, four, five or six serial items were tested on probed recall of Braille letters they could either name or discriminate. (Editor/RK)

Two experiments examined the question of whether blindfolded young children and congenitally blind children show mental practice effects for blind movements that cross the body midline. Results suggested that young children with sight can show mental practice effects in the absence of visual cues. (GLR)

This study explored tactile retention by children with attention-demanding and modality-specific distractors. (Author)

This research tested the hypothesis that grouping has adverse effects on the recall of tactual shapes but facilitates the recall of tactual letters on the assumption that this depends on different processes. A further question was the relation of grouping to letter recall span (set-size).

The hypothesis that letters can be matched on the basis of tactual physical features was tested in three experiments with blind Braille-reading children. (Editor)

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

A new psychological test battery was designed to provide a much-needed comprehensive tool for assessing the perceptual and cognitive abilities of visually handicapped children in using active touch. The test materials consist of raised-line, raised-dot, raised-surface shapes and displays, and familiar and novel 3-D objects. The research used 20…
