Abstract: | The beliefs that individuals hold about knowledge and knowing have been the focus of a growing body of work on “personal epistemology.” There has been general agreement among researchers about a developmental trajectory of epistemological understanding that takes place in adolescence and adulthood. Rarely has this research included children, however, and we know little about the origins of epistemological awareness or its early development. A separate group of researchers have investigated children's “theory of mind,” or the ability to understand others’ beliefs, actions, and desires, with primary attention to the onset of this cognitive achievement between the ages of 3 and 5. This article reviews the theoretical foundation for a proposed relation between these constructs, and reports on an exploratory investigation with 3–5 year olds, in which epistemological level was significantly related to theory of mind ability. Results are discussed in relation to a general timeline depicting the development of children's beliefs about knowledge and knowing, a process that involves an ongoing tension between objective and subjective perspectives. We propose that the trajectory of epistemological development be expanded to include an initial period of egocentric subjectivity that characterizes epistemological thinking prior to the achievement of theory of mind. |
