“…The sequential effect has been widely and robustly observed with the physical properties of sensory stimuli, such as the loudness and brightness of sensory stimuli or the size of visual objects (Holland & Lockhead, 1968;Petzold & Haubensak, 2001;Ward & Lockhead, 1970). Also, the sequential effect has been found with more complex, nonphysical properties, such as price, performance in sports, auditions for the American Idol television show, and cooperativeness in a series of strategic choice decisions (i.e., prisoner's dilemma games; Damisch, Mussweiler, & Plessner, 2006;Matthews & Stewart, 2009;Page & Page, 2010;Vlaev & Chater, 2007). Recently, it has been shown that the sequential effect is observed even for subjective decisions on the properties of items whose external true value is undefined; Kondo, Takahashi, and Watanabe (2012) investigated the sequential effect in face attractiveness judgments and found that the attractiveness ratings were biased toward those on the preceding trials (i.e., response-response sequential effect).…”
