The developmental sources of the link between stylistic externality and food-related externality found in the obese by Schacter and others were explored by testing whether the externality phenomena that have been found to differentiate obese and normal adults are also discriminators of obese and normal children. The results suggest that obese children as young as 7-12 years of age show an external responsiveness to salient food cues but not yet a generally external perceptual style. The implications of these findings for the development of obese externality are examined.
