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.

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…

Presents the results of a study concluding that poorer oral stereognostic skills may not be indicative of poor speech performance. (TO)

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)

By monitoring skin conductance and heart rate of 19 psychopathic, 21 neurotic, and 26 normal juvenile delinquents, it was concluded that the psychopathic autonomic characteristics resides in lower initial reactivity and not in more rapid adaptation, at least in response to a simple auditory stimulus.
