The Effects of Children on Parents: Adoptee Genetic Dispositions and Adoptive Parent Psychopathology

The purposes of this experiment were to investigate the effects of age, item type, and culture on the mental-real distinction made by children. A sample of 42 children (21 affluent and 21 deprived) in three age ranges (3- and 4-year-olds, 5-and 6-year-olds, and 7- and 8-year-olds) participated. Nine items were used. The behavioral-sensory and public-existence criteria (Wellman &; Estes, 1986) were used to gauge the children's ability to make the distinction. Contrary to previous research findings, the 3- and 4-year-olds in this study were unable to make the mental-real distinction. An age-related improvement in making this distinction was observed, and item type affected the mental-real distinction. The affluent children consistently outperformed their deprived counterparts. This finding was partly construed as evidence for the influence of culture on the ability to make this distinction in these age groups.
