Abstract：
Previous research described different cognitive processes on how individuals process distributional information. Based on these processes, the current research uncovered a novel phenomenon in distribution perception: the Endpoint Leverage Effect. Subjective endpoints influence distribution estimations not only locally around the endpoint but also influence estimations across the whole value range of the distribution. The influence is largest close to the respective endpoint and decreases in size toward the opposite end of the value range. Three experiments investigate this phenomenon: Experiment 1 provides correlational evidence for the Endpoint Leverage Effect after presenting participants with a numerical distribution. Experiment 2 demonstrates the Endpoint Leverage Effect by manipulating the subjective endpoints of a numerical distribution directly. Experiment 3 generalizes the phenomenon by investigating a general population sample and estimations regarding a real-world income distribution. In addition, quantitative model analysis examines the cognitive processes underlying the effect. Overall, the novel Endpoint Leverage Effect is found in all three experiments, inspiring further research in a wide area of contexts.
摘要：
先前的研究描述了个体如何处理分布信息的不同认知过程。基于这些过程,当前的研究发现了分布感知中的一种新现象：端点杠杆效应。主观端点不仅会影响端点周围的局部分布估计，还会影响分布整个值范围的估计。该影响在接近相应的端点处最大,并且朝向值范围的相对端在大小上减小。三个实验研究了这种现象：实验1为参与者呈现数字分布后的终点杠杆效应提供了相关证据。实验2通过直接操纵数值分布的主观端点来证明端点杠杆效应。实验3通过调查一般人口样本和有关现实世界收入分配的估计来概括该现象。此外,定量模型分析检查了影响背后的认知过程。总的来说,在所有三个实验中都发现了新的终点杠杆效应，在广泛的背景下激发进一步的研究。
