Preference and the specificity of goals

In this study, the authors examined (a) the effect of changes in the need to eat on expressed preferences for foods that are appropriate for different times of day and (b) whether that need is directed toward food in general or foods contextually appropriate to the time of day. Previous findings suggest that, when the goal is active relative to when it is inactive, items relevant to satisfying a goal increase in value but items unrelated to that goal decrease in value. The authors observed that, when people needed to eat, they sought foods that are contextually appropriate to the time of day of the study. Hence, the goal they sought to fulfill was narrower than seeking foods in general.
