A cell-by-cell analysis of finger movements of 16 blind adolescent braille readers was conducted to separate, catalog, and measure the components of scanning movements across braille cells as a function of reading proficiency. Results confirmed the superiority of bimanual reading and suggested that the two hands may perform different functions.…

Different materials that are used in manufacturing long cane shafts were assessed for their ability to transmit vibration and their sensitivity to tactile information, flexibility, and durability. It was found that the less flexible a cane shaft is, the better it transmits vibrations that are useful for discriminating surface textures and that…

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 paper presented at the National Convention of the American Cleft Palate Association (1968).

Four major types of interaction of stimulus dimensions based on perceptual research are described: integral, configural, separable, and asymmetric separable. Implications of these interactions for concept and choice processes are discussed. (Author/DEP)

Infants aged 3, 5, and 7 months were shown solid objects and comparable intangible images of objects both within and beyond possible arm's reach. The infants' emotional reactions and reaching behavior in the presence of the image stimuli were found to be very similar to their responses to the solid objects. (Author/JMB)

As part of an ongoing evaluation of the Tactile Vocoder, a device that allows the acoustic waveform to be felt as a vibrational pattern on the skin, two prelingually profoundly deaf teenagers reached criterion on a 50-word vocabulary (live voice, single speaker) after 28.5 and 24.0 hours of training. (Author/DB)

The linguistic abilities of three adult deaf-blind subjects who acquired language through the Tadoma method (involves monitoring a speaker's articulatory motions by placing a hand on his face) were examined. The subjects' English language abilities were excellent, suggesting that the tactile sense is adequate in highly trained Tadoma users in…

Five male learning disabled students (eight to 13 years old) learned more words using the nonpreferred hand in tactile processing to remediate reading than with the preferred hand. (CL)

Signs selected from lists used in studies with mentally retarded and autistic children and previously rated for visual iconicity were presented tactilely to 13 blind adults and adolescents. Visual and tactile ratings were found to be very similar across blind, deaf, and hearing-sighted adults and hearing-sighted children. (Author/CL)

Examination of hypothesis-testing and nonlinguistic symbolic abilities of 10 language impaired and 10 language normal children revealed that language impaired Ss performed significantly more poorly than controls on haptic recognition tasks and on a portion of the discrimination learning task. No differences were found between the groups' concept…
