Pigs
Sus scrofa domesticus
Summary
Pigs demonstrate cognitive abilities in specific domains--such as spatial memory, object discrimination, and social learning--that are sometimes compared to those of young children or dogs. However, cross-species cognitive comparisons are inherently limited, as different species excel in different domains (Marino & Colvin, 2015).
Cognitive Abilities
Evidence Summary
Cognitive abilities: Pigs have been extensively studied and consistently demonstrate remarkable intelligence: Problem-solving: - Can learn to operate joystick-controlled video games - Navigate complex mazes - Use mirrors to locate hidden food (mirror-mediated spatial awareness (using mirror reflections to locate hidden food — Broom et al., 2009, though a replication attempt by Gieling et al., 2014 found weaker results)) - Learn from watching other pigs Memory and learning: -
