Peer reviewedMoricca, Larry S. – Journal of Visual Impairment and Blindness, 1980
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)

Download full textNewman, Slater E.; And Others – 1980
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…

Berla, Edward P. – New Outlook for the Blind, 1972
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)

Peer reviewedMangold, Sally S. – Journal of Visual Impairment and Blindness, 1978
The extent to which a developmental program of tactile perception and braille letter recognition would affect errors in these abilities and reduce scrubbing and backtracking behaviors of 30 legally blind braille users (5-15 years old) was studied. (Author/BD)

Kershman, Susan M. – Education of the Visually Handicapped, 1976
A study involving 60 blind children (in grades k-2) was conducted to validate the hypothesized order of a series of tactual discrimination tasks and to determine the grade level(s) at which most "normal blind" children successfully perform simple tactual discrimination tasks presented on the Optacon.

Hanninen, Kenneth A. – Education of the Visually Handicapped, 1976
A study involving 29 sighted and 22 blind children in grades 3-12 was conducted to determine whether there are grade, sex, and handedness group differences in texture preferences and whether such preferences effect discrimination accuracy. (SBH)

FOULKE, EMERSON; WARM, JOEL – 1967
GROUPS OF 24 BLIND ADULTS (ALL SKILLED BRAILLE READERS) AND 24 SIGHTED COLLEGE STUDENTS WERE COMPARED ON A TACTUAL IDENTIFICATION OF FORM TASK IN WHICH RAISED DOTS WERE USED. THE TWO INFORMATION PARAMETERS, COMPLEXITY AND REDUNDANCY OF THE DOTS, WERE ASSESSED USING PUNCTIFORM METRIC FIGURES RESEMBLING HISTOGRAMS AND SIMILAR IN SIZE AND SPACING TO…
