"Our study provides the first empirical, systematic and longitudinal
investigation of infants reared with specific reduced
experience of eye contact and gaze behaviour owing to blindness
in the primary carer. The results clearly demonstrated
that no SIBP showed any autistic-like behaviours during the
early infant and toddler years of life, indicating that early
and ongoing interaction with a blind primary carer is not
associated with clear and pervasive/persistent atypicalities in
social-communication skills development."
