Sa. Rollman et Rd. Harrison, A COMPARISON OF DEAF AND HEARING SUBJECTS IN VISUAL NONVERBAL SENSITIVITY AND INFORMATION-PROCESSING, American annals of the deaf, 141(1), 1996, pp. 37-41
This investigation compared deaf and hearing subjects in the degree of
accuracy with which they can perceive visual nonverbal information ab
out people, their short-term recall of visual information and the exte
nt to which they focus on different parts of the body. Subjects were a
sked to gauge information about relationships between people shown in
photographs and later to indicate what they remembered from the photos
. Neither group demonstrated a statistically significant advantage in
accuracy or recall. When comparing the reasoning processes used by the
two groups to arrive at their conclusions it was found that deaf subj
ects were more than twice as likely as hearing subjects to base their
judgments upon hand and arm behavior.
