Indeed, our epistemological beliefs are thought to influence the questions we ask, the sources of information we place trust in, the certainty of our beliefs, and even academic outcomes (Greene, Sandoval, & Bråten, 2016a). However, most of the literature describes the developmental patterns of epistemological understanding in adolescence and adulthood, without characterizing the cause-effect mechanisms at play, particularly those in childhood. Although there is observational evidence suggesting that parent-child interactions are a context in which epistemological understanding may develop (Luce, Callanan, & Smilovic, 2013), and parent epistemological beliefs have been found to predict children’s critical evaluations of speakers who reason about evidence with varying competence (Suárez & Koenig, accepted), the role of adult influences on children’s epistemological development has not been examined experimentally. In the present study, I investigate: 1) How children develop the ability to consider the nature of knowledge within the context of conversation; 2) Whether improved epistemological understanding supports children’s critical thinking in informal social learning; 3) Whether cognitive self-control and verbal IQ moderate or mediate epistemological development; and 4) Whether individual differences in epistemological understanding relate to parent characteristics.endevelopmental mechanismsepistemological understandingexecutive functioningindividual differencessocial cognitiontheory of mindThesis or Dissertation
