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.

Interventions

Participants rehearsed dissatisfying aspects of the lunchtime meal they just ate.

BEHAVIORALNeutral rehearsal

Participants rehearsed their journey to campus that day.

BEHAVIORALSatisfying rehearsal task

Participants rehearsed satisfying aspects of the lunchtime meal they just ate.

Design outcomes

Primary

Measure	Time frame	Description
Ad libitum snack intake	Measured 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

Measure	Time frame	Description
Memory for general satisfaction	Measured 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.
Memory for satisfaction with meal satiety	Measured 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.

Other

Measure	Time frame	Description
Hunger before lunch	Measured before lunch (during baseline visit)	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.
Hunger after the bogus taste-test	Measured after the bogus taste-test (in second visit that took place 3 hours after the baseline visit)	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.
Hunger after lunch	Measured after lunch (during baseline visit)	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.
Hunger before the bogus taste-test	Measured before the bogus taste-test (in second visit that took place 3 hours after the baseline visit)	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.
