Infants' success in hiding tasks is influenced by the orientation of the cavities used as concealments. The infants ( n =23, aged 11–13 months) performed better than chance when the cavities were upright, and worse than chance when they were inverted. This confirms and extends results by Freeman et al. (1980). Implications for the concept of object permanence are discussed. 相似文献
