Ben co-authored a new paper published today in PNAS about the relationship between brain size and problem-solving ability in mammalian carnivores. We show that mammalian carnivores with larger brains relative to their body size are better able to solve a novel problem (opening a puzzle box). This was work done in collaboration with Sarah Benson-Amram, Kay Holekamp, Eli Swanson, and Greg Stricker.
Check out the video by Sarah Benson-Amram summarizing our results (embedded below) and the press release from the University of Michigan. It has also been covered by The New York Times, National Science Foundation, Scientific American, BrainDecoder, Popular Science, and New Scientist, ARS Technica, among others.
