In recent years, increasing attention has been given to the development of deaf children, though few studies have included Deaf parents. The present study examined emotional availability (EA) and functions of touch used by Deaf or hearing parents with hearing or deaf infants during free play. Sixty dyads representing four hearing status groups…

The purpose of the project was to gain information with which to improve the quality of tactual maps for the blind. Empirical studies of the pair-comparison type were conducted, using blind students as subjects, to determine discriminable sets of areal, linear, and point symbols made in plastic and to identify discriminable sets of linear and…

A brief review of selected research on tactual perception was reported to reveal a lack of theoretical perspective, definition problems, and emphasis on applied research. (CB)

The studies involving two blind adults evaluated a new system-- Trigemina--that relates visual information to blind persons by tactile stimulation through a matrix of 10 x 10 vibrating rods applied to a postage stamp-sized area of skin over the forehead. (Author/SBH)

The study demonstrates that, with a brief training period, deaf adolescents (N=8) can attain a high level of perceptual performance with a tactual speech system in discrimination of certain hard to lipread word pairs pronounced by both a male and a female speaker. (Author/SBH)

The study involving 96 undergraduates with no previous experience with braille investigated variables (such as size of the braille symbols) affecting the learning of braille. Data were analyzed in terms of the number of correct responses, item difficulty, and error patterns. Visual Ss did better than haptic Ss on the regular bralle items but not…

Sixty-four 8-year-old children were divided into fast and slow learner groups and trained on a tactile simultaneous discrimination task. Selective attention was measured in terms of percentage contact time per trial to the relevant dimension. Inter- and intracouplings per trial were also recorded. A multivariate analysis was carried out to examine…

Telephone interviews were conducted with 12 experienced blind adults to determine the strategies and techniques they employed in locating point, linear, and areal symbols and in following a track on a pseudo-map. (GW)

Three experiments were conducted which tested the orosensory acuity (or cutaneous sense acuity) and form discrimination via tactual perception of congenitally deaf secondary school students. (Author)

Examined was the use of immediate and continous corrective tactile feedback for the improvement of speaking intonation with 12 deaf students aged 12 to 16 years. (Author/DB)
