With foods used as the target stimulus, this task is purported to measure “self-controlled food choice”. In general, the ability to forgo an immediate reward (e.g., a small portion of a “comfort” food) for a delayed benefit (e.g., a larger portion of that food) is the outcome of interest in a delay discounting task. Using this task, an indifference point is calculated, which is the point at which participants switch from choosing a smaller immediate reward to choosing a larger delayed reward; operationally, lower indifference points indicate greater self-controlled food choice, and is associated with lower BMI and lower obesity rates.
