在两个实验中，我们研究了身体姿势是否会影响人们对数量的估计。根据心理数字线理论，人们在心理上沿着一条线来表示数字，左边的数字较小，右边的数字较大。我们假设，偷偷地让人们向右或向左倾斜会影响他们的定量估计。参与者站在Wii平衡板上回答评估问题。研究人员对受试者的姿势进行了调整，让他们在回答一些问题时稍微向左倾斜，回答一些问题时稍微向右倾斜，回答一些问题时笔直站立。关键是，参与者没有意识到这种操纵。受试者向左倾斜时的估计值明显小于向右倾斜时的估计值。
In two experiments, we investigated whether body posture influences people's estimation of quantities. According to the mental-number-line theory, people mentally represent numbers along a line with smaller numbers on the left and larger numbers on the right. We hypothesized that surreptitiously making people lean to the right or to the left would affect their quantitative estimates. Participants answered estimation questions while standing on a Wii Balance Board. Posture was manipulated within subjects so that participants answered some questions while they leaned slightly to the left, some questions while they leaned slightly to the right, and some questions while they stood upright. Crucially, participants were not aware of this manipulation. Estimates were significantly smaller when participants leaned to the left than when they leaned to the right.
