A suggested ethological explanation for Sullivan & Birch (1980).
Potts, H. W. W.
Abstract: Sullivan & Birch found that, in 4/5-year-olds, experience with one version of a food produced a decrease in preference for other versions of that food (Developmental Psychology, 1990, 26, 546-551). Primates' diets contain many foods where the flavour indicates differences in toxicity and nutritional value (e.g. fruit (over)ripening). Thus, to automatically avoid variations from a flavour previously experience as safe and nutritious would be of survival value.
