The inheritance of desired characteristics: Children's view of the role of intention in parent-offspring resemblance.
Two studies examined children's beliefs about maternal intention as a mechanism for trait inheritance. In Study 1, 42 preschool-aged (4 to 5 years old) children and 81 adults were shown pictures of adult women (mothers) and were asked to identify their daughters. In the critical condition participants were asked to choose between a girl who shared an attribute with the mother and a girl who had the attribute desired by the mother. Trait types included physically heritable traits, nonheritable traits, and beliefs. Results from this study suggest that preschoolers do believe that maternal intention plays a role in the inheritance of physical traits. Study 2 was designed to determine whether preschoolers recognize limits on both the efficacy and the timing of maternal intention. Results suggest that children see some properties as outside of maternal control. Further, they do seem to see maternal intentions as operating prior to birth. One finding of these studies is that preschoolers may not have strong intuitions that offspring will resemble their parents. In addition, children seem to have different intuitions about the mechanisms of inheritance than do adults.
