About this 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. 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.

Treatment and study plan

Satisfying rehearsal task

Behavioral

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

Dissatisfying rehearsal task

Behavioral

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

Neutral rehearsal

Behavioral

Participants rehearsed their journey to campus that day.

Primary outcomes

  1. Ad libitum snack intake

    Time frame: 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 outcomes

  1. Memory for general satisfaction

    Time frame: 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.

  2. Memory for satisfaction with meal satiety

    Time frame: 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 outcomes

  1. Hunger before lunch

    Time frame: 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.

  2. Hunger after lunch

    Time frame: 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.

  3. Hunger before the bogus taste-test

    Time frame: 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.

  4. Hunger after the bogus taste-test

    Time frame: 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.
