Herman CP, Polivy J. External cues in the control of food intake in humans: the sensory-normative distinction. Physiol Behav. 2008 Aug 6;94(5):722-8. doi:10.1016/j.physbeh.2008.04.014
Why we cite it
A review of the history of external cues in human food intake, from Schachter’s proposal that obese individuals are ”especially (and perhaps exclusively)” responsive to them, through its challenges and revival. The authors ”introduce a distinction between normative and sensory external cues”: normative cues (e.g., portion size) indicate appropriate intake, sensory cues (e.g., palatability) the food’s hedonic appeal. ”We propose that normative cues affect everyone, whereas sensory cues, while affecting everyone, have a more powerful effect on some types of individuals (e.g., the obese) than on others.” It is a proposal in a review, not a test.
