Abstract
The featured article by Sakurai and Tomonaga (2024) in this issue has set out to test to what extent dolphins can estimate relative differences between pairs of object numbers by echolocation. For this they used three consecutive experiments with multiple controls and compared their data statistically to existing data from visual experiments done on other species. Previous studies already indicate that dolphins can visually estimate relative numerosity (e.g., Jaakkola et al., 2005; Yaman et al., 2012). Therefore, the goal of the present study was to investigate the dolphin's capacity to apply Weber's law (quantity judgments are more accurate proportional to the quantities investigated) to two sets of object quantities under sonar evaluation.

樱井和Tomonaga（2024）在本期杂志上的专题文章开始测试海豚在多大程度上可以通过回声定位来估计物体数量对之间的相对差异。为此，他们使用了三个连续的实验，有多个控制，并将他们的数据与现有的其他物种的视觉实验数据进行了统计比较。先前的研究已经表明，海豚可以通过视觉来估计相对数量(例如，Jaakkola等人，2005；Yaman et al., 2012)。因此，本研究的目的是研究海豚在声纳评估下将韦伯定律（数量判断与所调查的数量成正比）应用于两组物体数量的能力。（PsycInfo Database Record (c) 2024 APA，版权所有）。
