“…We argue that through studying the effects of social influence on perceptual decision making, we can potentially probe deeper into the brain mechanisms through which social factors exert their influence. There are many studies in which social psychologists have used perceptual paradigms to examine the influence of other people's opinions on decision-making processes (e.g., Asch, 1952Asch, , 1956Martin, 1998;Moscovici, Lage, & Naffrechoux, 1969;Moscovici & Personnaz, 1980). Similarly, neurophysiologists have utilized perceptual paradigms to unravel the neuronal circuitry underlying perceptual decision making in the monkey (e.g., Britten, Newsome, Shadlen, Celebrini, & Movshon, 1996;Dodd, Krug, Cumming, & Parker, 2001;Newsome, Britten, & Movshon, 1989;Uka & DeAngelis, 2004).…”
