Habituation
A decrease in response to a stimulus that is presented repeatedly and has no significant consequence, one of the simplest forms of learning, found across species. It is distinguished from sensory adaptation and fatigue by features such as recovery after a pause and restoration of the response when a different stimulus intervenes. In emotion research, habituation of physiological responses to repeated stimuli must be considered when interpreting declining responses over a session, because a smaller response does not by itself indicate that an emotion has been processed or resolved. Affective computing promises to infer emotion as if it were a system metric. The evidence on facial movements and autonomic signals, together with questions of consent, explains why every metric in this artifact is an artistic value. Why a restorative experience can leave the underlying difficulty unchanged: negative reinforcement, experiential avoidance, acute mood effects of exercise, rumination and the peak-end rule. The works the definition rests on, with the level of evidence each was appraised at. (2009).

Expert consensus on basic learning; it does not address emotional processing.Where the site uses it
