The present research adopted the basic anchoring paradigm, used time words and physical duration as numerical anchors and physical anchors separately, and explored the effects of anchors that with different presentation forms or magnitudes on decision processes of time production (experiment 1) and verbal estimation (experiment 2). 55 undergraduate students were recruited to participate in the present study. The results indicated that the numerical anchors provide starting points for verbal estimation and assimilated the verbal estimates at the decision-making process; while the physical anchors were used as standard of comparison in time production and verbal estimates and assimilated time productions but contrasted verbal estimates at the decision-making process.
