Aspects of developmental sequences and structures were assessed in low‐ and high‐Functioning autistic and non‐autistic developmentally disabled children. Specific developmental issues examined included sequences, regressions and profiles. Classification into the high‐ or low‐functioning groups was based on a full stale IQ cutoff of 50. In general, there were few differences in the sequences of development among the groups. However, the autistic children were more likely than non‐autistic children to display developmental regressions and unevenness across developmental domains. These developmental peculiarities were more pronounced in the low‐ as compared to high‐functioning autistic children. These findings are discussed with regard to issues of developmental processes, classification and autism.
