摘要：

采用基本锚定范式，以时间词和物理时距分别作为数字锚定值和物理锚定值，探讨了不同形式和大小的锚定值如何影响产生法（实验1）和口头估计法（实验2）中的时距估计的决策过程。55名在校大学生参加了本次实验。实验结果表明，数字锚定值被作为时距估计的调整起始点，对决策过程中的数值估计产生同化影响；物理锚定值则被作为时距估计的比较标准，同化产生法中的决策估计值，对口头估计法中的决策估计值却产生对比影响。

Abstract:

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.

Key words: duration estimation, anchoring effect, numerical anchor, physical anchor
