Nutrient-Specific System v. Full Fact Panel: Understanding Nutritional Judgment Using Lens Model Analysis
Year: 2017
Type: article
Abstract: Current food labels include comprehensive nutritional information, but evaluations of their effects on judgments of nutritional quality and food choice are scarce.Building on previous empirical research that demonstrates that amount and complexity of information is negatively related to judgment accuracy, this study used an experimental design to evaluate nutritional information labels of varying complexity.Lens model analysis (Brunswik, 1955;Cooksey, 1996;Hammond, 1955;Stewart, 1976) was used to quantitatively compare individuals' judgment accuracy to a gold standard nutritional quality criterion in three conditions that implemented front-of package (FOP) labels.The conditions were: no highlighted information, information highly related to nutritional quality highlighted, and information marginally related to nutritional quality highlighted.Findings indicate that different FOP labels had different effects on accuracy, but there were no effects of FOP labeling on judgment consistency, model agreement, or nutritional choice.Implications for understanding efforts to improve American food choices and reducing obesity are discussed.González-Vallejo, for her guidance, mentorship, and support throughout the development of this study and document.I also thank my committee members, Dr. Jeffrey Vancouver and Dr. Sarah Racine for their time and insightful assistance.Many thanks also to Drs.Carlson, Porter, and Williams for their inspiration and instruction in my study of psychology and statistics, and to Drs.Berheide, Guthman, and Pulsford, for teaching me a love for writing and thinking.I am
