Neutral Levels
Neutral levels are a concept in the adaptation-level phenomenon which is the tendency to judge novel stimuli based on our perceptions of stimuli experienced in the past. Our neutral levels are the intensity at which stimuli and events are comfortable to us - feeling not too hot or cold, whether music is too loud or too quiet, and whether a situation is pleasant or unpleasant. We base our experiences with novel stimuli and situations on our neutral levels that are a result of what we have already experienced.
