Q

procedure

A

Session 1

  • Participants assigned to 1 of 2 groups (Love and Control group)
  • Upon arrival, participants were told that their data would be entered into a computer, that would later generate a personal profile for them
  • Participants then completed 5 questionnaires: FHI, Food preferences Questionnaire, Restaurant Questionnaire as well as two filler questionnaires which included personality Questionnaire and Desirability Scale
  • Filler questionnaires were to distract from true aim of experiment.

Session 2

  • Participants returned to the location, where they received false feedback on their performance from Session 1.
  • The critical item was embedded in their “computer generated” profiles which read: “You loved asparagus the first time you ate it.”
  • Participants then viewed 20 slides each of which was displayed for 30 seconds, and completed 4 ratings of each slide. The slides contained photographs of common food including the critical item Asparagus.
  • The photos were rated based on their degree of appetite or disgust, and the properties of the photograph’s origins.
  • Participants then completed the FHI, Food preferences questionnaire and Restaurant Questionnaire for the second time.
  • Also additionally completed a memory of belief questionnaire
