Brief Summary

This study examined whether remembered meal satisfaction (encompassing memory for meal liking and satiety) can be manipulated in the laboratory and whether this influences later food intake.

Detailed Description

This study examined whether remembered meal satisfaction (encompassing memory for meal liking and satiety) can be manipulated in the laboratory and whether this influences later food intake. In a between-subjects design participants consumed a fixed lunch and then rehearsed the satisfying or dissatisfying aspects of the meal, or a neutral experience (control), in order to manipulate memory for meal satisfaction. Three hours later, in a second visit to the laboratory, participants completed a bogus taste-test to measure food intake and meal memory measures.

Primary Outcome Measures
NameTimeMethod
Ad libitum snack intakeMeasured during second visit that took place 3 hours after the baseline visit

Energy intake (kcal) measured from a bogus taste-test task. Lower intake in those in the satisfying rehearsal condition compared to the control condition and greater intake in the dissatisfying rehearsal condition compared to the control condition were expected.

Secondary Outcome Measures
NameTimeMethod
Memory for satisfaction with meal satietyMeasured during second visit that took place 3 hours after the baseline visit

Memory for general satisfaction with the lunchtime meal was measured via two questions: 'How satisfied were you with how filling the lunchtime meal was?' and 'How dissatisfied were you with how filling the lunchtime meal was?'. Responses were measured using 100-point visual analogue scales with anchors 'not at all' and 'extremely' (0-100). A higher score in those in the satisfying rehearsal condition compared to the control condition and a lower score in the dissatisfying rehearsal condition compared to the control condition were expected.

Memory for general satisfactionMeasured during second visit that took place 3 hours after the baseline visit

Memory for general satisfaction with the lunchtime meal was measured via five questions: 'Overall, how satisfying did you find the lunchtime meal?', 'Overall, how dissatisfying did you find the lunchtime meal?', 'I liked the lunchtime meal', 'How satisfied were you with the taste of the lunchtime meal?' and 'How dissatisfied were you with the taste of the lunchtime meal?'. Responses were measured using 100-point visual analogue scales with anchors 'not at all' and 'extremely' (0-100). A higher score in those in the satisfying rehearsal condition compared to the control condition and a lower score in the dissatisfying rehearsal condition compared to the control condition were expected.
