Brief 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
Detailed Description: 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 Most commonly participants are asked to rate their hunger desire to eat fullness and prospective consumption For example researchers have demonstrated that hunger and fullness stem from different physiological processes eg different gut-peptides and neurotransmitters and serve different purposes eating initiation hunger meal termination fullness and accordingly expect participants to rate the two sensations independently However participants treat them as opposite poles on a common continuum Additionally in focus group analysis consumers often use researcher-defined distinct terms interchangeably hungerdesire to eat fullness lack of desire to eat However the distinction between these sensations is clinically important Hunger and fullness do not always change reciprocally and equally in clinical conditions Hunger can change without a shift in fullness and the reverse has also been reported Investigators believe reporting sensitivity selectivity and reliability can be improved by training participants on the terminology of appetitive sensations prior to testing just as any bench researcher would calibrate their instruments before measurements 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
