When comparing autistic girls and boys between the ages of 6 and 15 with similar IQs and levels of autism, girls were shown to use far more social words—that is, words that make reference to other people, including family and friends—than their male counterparts. In particular, girls used significantly more words to talk about friends than boys did. Discussion about family was relatively consistent in both groups.
