摘要: The prediction of upcoming events is importance not only to humans and non-human primates but also other animals that live in complex environments with lurking threats or moving prey. In this study, we examined motion tracking anticipatory looking dogs two eye-tracking experiments. Experiment 1, presented pet (N = 14) a video depicting how players threw Frisbee back forth multiple times. horizontal movement the explained substantial amount variance dogs' eye movements. With increasing duration video, looked at catcher before arrived. 2, showed (N = 12) same recording. This time, however, froze rewound parts examine would react surprising (i.e., hovering midair reversing its direction). again captured attention, particularly when was frozen for first time. Additionally, faster moved forward compared it rewound. We conclude paradigms provide promising tools future cognitive research canids.
