Abstract
This longitudinal study examined various intellectual and social experiences older siblings create for or with their infant siblings, and how these experiences relate to sibling status variables and infant cognitive level. Eleven categories of firstborn-created intellectual and social experiences were coded from free play of 69 infant-sibling dyads when infants were 12 1 2 and 17 1 2 months old. Infant cognitive level was assessed with the Bayley MDI and from the developmental level of infant solitary play. Results suggested that infants of widely spaced dyads experience a more intellectually and socially stimulating environment than infants of closely spaced dyads. No relationships were found between infant cognitive level and any firstborn-created experience or age-spacing. These results were discussed in light of additional findings relating variations in sibling age-spacing to variations in household structure in middle-class, two-parent families.
