Votaw 1992), a reduction in the appeal of the food (Inman 2001), and goal fulfillment (Laran and Janiszewski 2009). Given our focus on changes in liking within a consumption episode (e.g., on hedonic appreciation across bites), we will focus on habituation wherein habituation refers to in both physiological and behavioral responses to eating that occur as an eating “reductions episode progresses” (Epstein et al. 2009, p. 384). In the domain of food hedonics, habituation is characterized by a decrease in the ability to appreciate flavor, as opposed to a loss in the ability to taste flavor (Rolls et al. 1983). Hedonic Escalation Hedonic escalation is an increased appreciation for an experience over repeated trials in a single consumption episode (Epstein et al. 2008, p. 254). hedonic escalation is consistent with anecdotal experiences (see the wine vignette), there is surprisingly little empirical support for the phenomenon. The lack of evidence is a consequence of the research agenda in the food hedonics literature and the motivated eating literature. Wherein both literatures have investigated adaptation, only the motivated eating literature has investigated behaviors that are consistent with a sensitization response (e.g., Bellisle and Le Magnen 1980; Cornell et al. 1989; Yeomans 1993). For example, Yeomans (1996) found that a highly palatable pasta (i.e., sauce seasoned with oregano) was eaten at an accelerated rate (e.g., more pasta was eaten in the second two minutes than in the first two minutes), whereas a less palatable pasta (i.e., unseasoned sauce) was not. Consequently, evidence for hedonic escalation must be inferred from evidence showing increased consumption, a tenuous inference given that motivation and liking are disassociated in some situations (Berridge 2009; Grabinsky, Morewedge, and Shiv 2014; Finlayson, King, and Blundell 2007; Morewedge, Huh, and Vosgerau 2010) but not others (Havermans et al. 2009; Rolls et al. 1981a).
