Previous studies on anchoring effect have shown that knowledge activated by an anchor plays an important role. If this is true, a number will not be necessarily presented as an anchor and stimuli which active different knowledge will suffice to produce anchoring effect. In the present study, we examined whether stimuli that would activate different knowledge would work as “anchor.” We found that presented number as an anchor affected numerical estimation more than stimuli that would be assumed to activate different knowledge. These results suggested that the presented specific number as an anchor played an important role in producing anchoring effects.
