The “Baby Sib” Approach
• Study autism from birth
• Need to study 100 babies
just to find 4 or 5 or 15
with an ASD
• Studies autism only in multiplex
families – are genetics different?

• Investigates autism as
it occurs in the population
• Investigates the feasibility
of on-site screening and scoring

Why study LATERALITY?
• Hemispheric specialization is crucial aspect of
language development
• Structural asymmetries in language areas
prenatal in origin
• In older children and adults, left hemisphere
predominance of language response, especially
in frontal and temporal cortex
• Greater right hemisphere involvement in
pragmatics
• Less known about normal development of
functional asymmetries or how this may go awry
in ASD
Brain Response to Speech During Sleep?

al., (2002, Science)
Current Study
• Goals
– Extend prior work to include infants and toddlers with
subsequent confirmation of ASD
– Examine development of left-hemisphere
predominance of language response in typical
children and laterality abnormalities in ASD
