从产品评估到医疗决策，再到数轴估计，在判断和决策过程中，左数字效应被广泛观察到。例如，3美元被认为比2.99美元要贵得多，而在数轴上，“801”被估计在“798”的右边太远了。虽然对判断和决策行为的影响的后果已被记录在案，但影响的来源尚未得到很好的确定。当前工作的目标是将左数效应的研究扩展到一个新的复杂判断活动，并评估个人水平上的影响程度是否可以从一个更简单的数字技能任务的表现中预测出来，其中左数效应最近也被观察到。在三个实验中（N= 434），成年人完成了一个判断任务，在这个任务中，他们对假想的大学录取申请人的实力进行评估，并完成了一个自定进度的数轴估计任务。在所有实验中，在大学录取任务中发现了小或中等的左数效应，在数线估计中发现了大的效应。观察到个体水平的差异，但在两个任务中的影响程度之间没有关系。这些发现为新的多属性判断任务中的左数字效应提供了证据，但没有证据表明这种表现可以从简单的数字技能任务（如数轴估计）中预测出来。
A left digit effect has been broadly observed across judgment and decision‐making contexts ranging from product evaluation to medical treatment decisions to number line estimation. For example, $3.00 is judged to be a much greater cost than $2.99, and “801” is estimated strikingly too far to the right of “798” on a number line. Although the consequences of the effects for judgment and decision behavior have been documented, the sources of the effects are not well established. The goal of the current work is to extend investigations of the left digit effect to a new complex judgment activity and to assess whether the magnitude of the effect at the individual level can be predicted from performance on a simpler number skills task on which the left digit effect has also recently been observed. In three experiments (N= 434), adults completed a judgment task in which they rated the strength of hypothetical applicants for college admission and a self‐paced number line estimation task. In all experiments, a small or medium left digit effect was found in the college admissions task, and a large effect was found in number line estimation. Individual‐level variation was observed, but there was no relationship between the magnitudes of the effects in the two tasks. These findings provide evidence of a left digit effect in a novel multiattribute judgment task but offer no evidence that such performance can be predicted from a simple number skills task such as number line estimation.
