Predictive coding theories suggest that core symptoms in autism spectrum disorders (ASD) may stem from atypical mechanisms of perceptual inference (i.e., inferring the hidden causes of sensations). Specifically, there would be an imbalance in the precision or weight ascribed to sensory inputs relative to prior expectations. Using three tactile…

Changes to a scene often go unnoticed if the objects of the change are unattended, making change detection an index of where attention is focused during scene perception. We measured change detection in school-age children and young adults by repeatedly alternating two versions of an image. To provide an age-fair assessment we used a bimanual…

Spatial abilities are fundamental to human functioning in the physical world. Spatial reasoning allows people to use concepts of shape, features, and relationships in both concrete and abstract ways, to make and use things in the world, to navigate, and to communicate. Surgeons, pilots, architects, engineers, mechanics, builders, farmers, trades…

Four elements of clinical programming must be considered during development in order for a software program to be truly useful in rehabilitation: presentation of a useful task; treatment parameters selectable by clinicians; data collection/analysis; and authoring capability. These criteria govern the development of all Brain-Link Software…

Project CREATE was a 4-year federally funded research program which sought to determine ways in which computer technology could improve the education of learning-disabled students. Early work on the project centered on the development of a theoretical and conceptual foundation; a hierarchical conceptual model was constructed that related school…

This study investigates children's spatial cognition in the microcomputer environment created by "HyperGami." Two categories of spatial cognition have been described: spatial visualization, which involves mentally rotating, manipulating and twisting two- and three-dimensional objects; and spatial orientation, which involves the ability…
