AU autism, DS Down syndrome, and TD typical development group; subscripts refer to average age (in months) at observation. Scores are number of children exhibiting a pattern (with percentage of group in parentheses). Group percentages may not sum exactly to 100% due to rounding. One and two asterisks indicate cell frequencies significantly below (subscripts) and above (superscripts) their expected values, p < .05 and < .01, respectively
