AB - Sampled 160 sibling pairs from 2-child families from 16 subgroups defined by the factors: Grade Level of Younger Sibling (kindergarten and 2nd grade), Age Spacing between Siblings (2 and 4 yrs), Sex of Younger Sibling, and Sex of Older Sibling. For 1/2 of the pairs, the younger sibling worked alone on an object-sorting task; for the remainder, the older sibling aided the younger and their interaction was recorded. Measures of the younger sibling's categorization style were obtained from a subsequent object-sorting task. Children aided by siblings made more groups than children who worked alone; those children aided by siblings 4 yrs older made larger groups and left fewer objects ungrouped than those aided by siblings 2 yrs older (p < .05). Sibling interaction behaviors were related to measures of categorization style. The study provides additional evidence of the importance of a child's siblings to his cognitive development. (19 ref.)
