Are Children "Intuitive Theists?" Teleological Reasoning about Purpose in Nature Deborah Kelemen Department of Psychology Boston University Separate bodies of research suggest that young children have a broad tendency to reason about natural phenomena in terms of a purpose and an orientation towards intention-based accounts of natural entity origins. This presentation explores these results further by drawing them together with recent findings in cognitive developmental research to address the following question: Rather than being "artificialists" in Piagetian terms, are children "intuitive theists" - disposed to view natural phenomena as resulting from non-human design? Specifically, I will review recent research from my own and other labs on preschool children's agency concepts and imaginary companions, their reasoning about biology and their "design stance" understanding of artifacts to suggest that, by around 5 years of age, the "intuitive theist" description may have explanatory value and practical relevance to our understanding of how a scientific understanding of nature develops.
