Two experiments investigated 5-month-old infants' amodal sensitivity to numerical correspondences between sets of objects presented in the tactile and visual modes. A classical cross-modal transfer task from touch to vision was adopted. Infants were first tactually familiarized with two or three different objects presented one by one in their…

In this article, we examine the extent to which children with autism and children with learning difficulties can be discriminated from their responses to different patterns of sensory stimuli. Using an adapted version of the Short Sensory Profile (SSP), sensory processing was compared in 34 children with autism to 33 children with typical…

Based on a thesis submitted by Dennis Pilgrim to the Graduate School, University of South Dakota, 1967.

Sighted subjects assembled puzzles under separate conditions of visual-haptic perception and used vision and touch simultaneously to illustrate visual-type involvement and links in haptic encoding processes. A cognitive component in perceptions was found. When visual input was inadequate or independent of haptic perception, tactual information was…

Three experiments examined whether 8.5-month-olds considered an object's width and compressibility when determining whether it could be inserted into a container. Results suggested that infants realized that large balls could fit into large but not small containers, whereas small balls could fit into both containers. Infants understood that large…

Full-term middle-class, full-term lower-class, and preterm infants were compared on cross-modal and visual intramodal functioning in order to determine whether cross-modal functioning would be impaired in infants born prematurely, or in full-term infants who were being raised in less advantaged environments.

Three experiments examined cross-modal transfer of shape between touch and vision in 1-month-olds, controlling for side bias and stimulus preference. Results did not provide good evidence that 1-month-olds can transfer information about smooth or nubby shapes from touch to vision. Findings highlight the need to control for side bias and stimulus…

This paper summarizes the results of a review of the empirical literature (1990-2005) focusing on use of assistive technology as a self-management tool for persons with intellectual disabilities. Forty investigations were identified which provided information on assistive technology to assist persons with disabilities to initiate and complete…

The Tactile Vision Substitution System converts the visual image from a narrow-angle television camera to a tactual image on a 5-inch square, 100-point display of vibrators placed against the abdomen of the blind person. (Author)

Examines 3-month-old infants' perception of "camouflaged" forms that were only visible when moving. Shows infants effectively use kinetic information to organize visual input in higher-order structures. (HOD)

Two experiments studied the impact of the nature of information available at different processing levels on differences in haptic (tactile) and in visual, free classification development. Found that exploration characteristics (involving simultaneous versus independent processing of stimulus dimensions) and presentation of the stimulus dimensions…

Tested the hypotheses that errors of ommission would occur more frequently than errors of commission and errors would be related to stimulus complexity. A total of 48 children from grades 1 and 3 were given a memory task (involving visual and haptic memory) for recognition of random polygons. (MS)

Explored are the possibilities of using amplification in three sensory modes (audition, vision, and touch) in the education of the aurally handicapped. (BD)
