The meaning, mechanism, and function of imitation in early infancy have been actively discussed since Meltzoff and Moores (1977) report of facial and manual imitation by human neonates. Oostenbroek etal. (2016) claim to challenge the existence of early imitation and to counter all interpretations so far offered. Such claims, if true, would have implications for theories of social-cognitive development. Here we identify 11 flaws in Oostenbroek etal.s experimental design that biased the results toward null effects. We requested and obtained the authors raw data. Contrary to the authors conclusions, new analyses reveal significant tongue-protrusion imitation at all four ages tested (1, 3, 6, and 9 weeks old). We explain how the authors missed this pattern and offer five recommendations for designing future experiments. Infant imitation raises fundamental issues about action representation, social learning, and brain-behavior relations. The debate about the origins and development of imitation reflects its importance to theories of developmental science.
