Summary

A fundamental limitation to the application of appetitive sensations is how they are measured. The most common approach relies on untrained individuals to self-report the sensations they experience under a given set of conditions. Investigators believe this is problematic because assumptions made about participant ratings are likely not valid. The proposed protocol will permit examination of whether training on appetite lexicon enhances the reliability of appetite ratings. Investigators also hypothesize that different preloads will induce different magnitudes of appetite sensations (hunger, fullness, desire to eat, and prospective consumption) depending on their energy density.

Lexicon training

Participants will receive training on the lexicon of appetite on up to 3 days during the training week. This will entail reading written definitions, watching an instructional video, eating exercises and completing training exams demonstrating they understand the distinctions between appetitive terms (hunger, desire to eat, fullness, and prospective consumption). The training will require about 30 minutes to complete. To ensure the success of training, participants must verbally describe the definitions of the outcome sensations to a member of the research team and complete a written quiz with at least 90 % correct responses. Failure to satisfactorily convey understanding of the concepts will result in an offer to repeat the training 2 more times or be rejected from the study.
