Running head: SATIATION OF DESIRE OVER TIME 1 Desire Over Time: The Multi-Faceted Nature of Satiation

Desire is dynamic in that enjoyment and wanting typically decline as one repeatedly consumes the same thing. This consequence of satiation arises in many fields, including economics (diminishing marginal utility), psychology (adaptation, habituation), food sciences (nutritional needs), advertising (wearout), and well-being (hedonic treadmill). Although researchers have often viewed satiation as an automatic meter that tracks the quantity consumed and inexorably leads to satiation, growing research indicates that satiation also has a malleable component rooted in perception and self-reflection. This chapter details the multi-faceted nature of satiation, offers a framework to capture its mechanisms, and discusses implications for influencing satiation through interventions and individual differences.
