Data for: Cognitive aids and food choice: real-time calorie counters reduce calories ordered and correct biases in calorie estimates

Description

Data from 344 participants of an online experiment on the sequential selection of ingredients in a sandwich-building choice exercise. Participants completed the experiment in one of two conditions: 1) a calorie information condition ("Calorie Information"), in which each ingredient had the number of calories that it would add listed next to it, and 2) a calorie summation condition ("Calorie Summation"), in which participants had calorie information about each ingredient and a counter automatically added up a running total number of the calories ordered across all ingredients as they were added.
