How We Get Our Bearings
Research has suggested that animals and young children mainly rely on geometric cues (lengths, distances, angles) to help them get reoriented after a change of scene. Human adults, however, can also make use of feature cues (color, texture, landmarks) to get a sense of where they are. But which method...

Being Bullied Has Its Benefits for Groundhogs
