Peer reviewedBertenthal, Bennett I.; Fischer, Kurt W. – Developmental Psychology, 1978
Presents a study of the development of self-recognition in infants from 6 to 24 months of age. The development of self-recognition is compared to the development of object permanence. (BD)

Peer reviewedAnd Others; Jackson, Elaine – Developmental Psychology, 1978
Presents a study of decalage between object permanence and person permanence. Decalage was influenced by environmental as well as stimulus factors with infants tested between 6- and 81/4-months/of-age. (BD)

Peer reviewedCampos, Joseph J.; Ramsay, Douglas S. – Developmental Psychology, 1978
Attempts to determine whether infants' performance in two search tasks is related to their entry into Stage 6 of object permanence development (thereby testing Piaget's claim that only Stage 6 infants possess the capacity for representation). (BD)
