:"Wanting is influenced by a variation in deprivation states, the presence of learned incentives for rewards, and the anticipated potential for a given stimulus to satisfy one’s desire based on past experience (Berridge, 1999; Berridge & Robinson, I998). Liking is somewhat more complex, and may vary due to the strength of relevant wanting states (e.g., strong vs. weak desire) and specific characteristics of stimuli such as sweetness. In humans, the extent to which novel sensory stimuli are liked may be influenced by the degree of their cognitive and perceptual interpretability—a quality referred to as “processing ease” or “fluency” (Reber & Schwarz, 2002; Reber, Winkielman, & Schwarz, 1998). Presumably, fluent stimuli are better liked because fewer cognitive resources are required in order to arrive at meaningful representations of the stimulus (Bush, Luu, & Posner, 2000; Vallacher & Nowak, 1999; Whittlesea,1993; Winkielman, Schwarz, Fazendeiro, & Reber, 2002). With repeated exposure, stimuli become progressively more interpretable, more easily understood, and therefore better liked."<ref>>Litman, Jordan.
