What have recent research studies been able to tell us about the neurobiological link to childhood autism?
  1. There is no significant relationship between the rate of growth in the womb and the probability of developing autism.
  2. Babies whose fetal growth is very slow (i.e., premature babies with low birth weights) are at higher risk for autism than both normal size and markedly oversize babies.
  3. The risk for developing autism as related to baby birth weight is substantially increased for both extremes of the baby weight continuum.
  4. The significant relationship between low baby birth weight and the likelihood of the child’s developing autism is only found in children who have a low birth weight because their mothers were taking drugs or alcohol during their pregnancy.
Explanation
Answer: C - Early research on the subject showed substantial correlations between low birth rate and the likelihood of developing autism. However, more recent research shows that babies who are extremely large when they are born are also at high risk for becoming autistic.
