About this study
Official title: Remembered Meal Satisfaction, Satiety and Later Snack Food Intake: A Laboratory Study
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Satisfying rehearsal taskBehavioural
Participants rehearsed satisfying aspects of the lunchtime meal they just ate.
Dissatisfying rehearsal taskBehavioural
Participants rehearsed dissatisfying aspects of the lunchtime meal they just ate.
Neutral rehearsalBehavioural
Participants rehearsed their journey to campus that day.
| Study group | Role | What they receive |
|---|---|---|
| Satisfying rehearsal | Experimental | Participants completed the satisfying rehearsal task where they rehearsed the satisfying aspects of the lunchtime meal. Receives: Behavioral: Satisfying rehearsal task |
| Dissatisfying rehearsal | Experimental | Participants completed the dissatisfying rehearsal task where they rehearsed the dissatisfying aspects of the lunchtime meal. Receives: Behavioral: Dissatisfying rehearsal task |
| Neutral rehearsal | Active comparator | Participants completed the neutral rehearsal task where they rehearsed their journey to campus that day. Receives: Behavioral: Neutral rehearsal |
What is being measured
The primary outcome is the main question the study is designed to answer.
Ad libitum snack intake
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.
Measured: Measured during second visit that took place 3 hours after the baseline visit
Secondary outcomes (2)
Memory for general satisfaction
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.
Measured: Measured during second visit that took place 3 hours after the baseline visit
Memory for satisfaction with meal satiety
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.
Measured: Measured during second visit that took place 3 hours after the baseline visit
