Dataset for "Cross-modal perception of puppies and adult conspecifics in dogs (Canis familiaris)"

We investigated if dogs have a cross-modal mental representation of conspecific age class using a cross-modal matching paradigm. In Experiment 1, dogs were presented with images of an adult dog and a puppy projected side-by-side on a wall while vocalization of either an adult dog or a puppy was played back simultaneously. In Experiment 2, we administered the same paradigm within an eye-tracking experiment, to investigate whether the results would be replicated when analyzing the dogs’ gaze behaviour in a more detailed way.
Here we provide the data, R code and videos.

本研究采用跨模态匹配范式（cross-modal matching paradigm），旨在探究犬类是否具备对同种个体年龄层级（conspecific age class）的跨模态心理表征（cross-modal mental representation）。实验1中，研究人员将成年犬与幼犬的图像并排投射于墙面，并同步播放成年犬或幼犬的叫声。实验2将该范式应用于眼动实验（eye-tracking experiment），以期通过更细致的犬类注视行为分析，验证实验1的结果是否可复现。本研究公开提供实验相关数据、R代码及实验视频。
