- Score: descriptions of food-related events as specific stimuli.
- Do NOT score references to thoughts or internal processes without a specific external sensory
experience.
- Do NOT score references to circadian rhythm or passage of time without description of external
sensory experience.
Note: There must be a specific short-term physical stimulus affecting eating behavior.
