Note. ADOS S+C = Autism Diagnostic Observation Schedule: Social and Communication Total. The ADOS consists of four modules, and the individual being evaluated is given just one module, depending on the level of expressive language and chronological age. Each module has different cutoff scores and should not be considered equivalent. One TDC participant was not administered the ADOS and one AIQ participant received an older version of the ADOS (version 1988), which is not reported above. TDC = Typical Developing Control, AIQ = Average IQ, and LIQ = Low IQ.
