J. Yamamoto et al., Establishing joint visual attention and pointing in autistic children withno functional language, PERC MOT SK, 92(3), 2001, pp. 755-770
Joint visual attention is defined as looking where someone else is looking.
The purpose of this study was to examine the conditions for establishing j
oint visual attention in autistic children who have no functional speech. A
n experimenter, sitting facing the child, looked at one of six pictures nea
r the child. Analysis showed that joint visual attention to stimuli behind
the child and therefore outside of the visual field occurred at a higher ra
te when the visual angle between the stimuli was about 60 degrees. Spontane
ous pointing at the target object increased with training which included fe
edback and physical guidance. These results are discussed in terms oi the e
ffects of environmental variables and perceptual mechanisms on the emergenc
e of joint visual attention in autistic children. The possibility of using
an adult's social cues and expanding the child's visual field as a remedial
procedure is also addressed.
