We investigated whether observing a socius consuming food CSs and facially expressing like or dislike (US) changed their evaluation of food. During acquisition, subjects consumed neutral colored and flavored drinks, while watching a videotaped model drinking identical drinks and expressing his evaluation (neutral/dislike). The presence of particular flavors or of particular colors functioned as CS+/CS-. An evaluative learning effect was obtained when flavor but not color was contingent on the expression of dislike. This effect depended on local acquisition context cues. A double dissociation was observed between subjects' explicit beliefs and subjects' "evaluative knowledge".
