Abstract

Expected satiety informs self-selected portion sizes and thereby influences energy intake. At present the extent to which these beliefs are learned remains unclear. In an initial study the proposition that familiarity influences expected satiety was explored. Self-report measures of familiarity, along with other measures such as degree of liking, were collected for wine gums and milk chocolate, together with expected satiety estimates obtained using a psychophysical task. Familiarity was indeed significantly correlated with expected satiety, but only in respect of frequency of having eaten the food to fullness. In a second experiment a significant increase in expected satiety was observed after eating a large portion of wine gums at a subsequent test session. Together, these findings indicate that expected satiety changes in response to increased familiarity of eating a food to satiety. (c) 2012 Elsevier Ltd. All rights reserved.
