Autistic writer and primatologist Dawn Prince-Hughes describes seeing her own symptoms of exclusion and marginalization in the animals she watched and studied at the zoo: “I would see this kind of behavior with gorillas in captivity. They had nervous tics similar, if not identical, to mine: hair plucking, picking at scabs, scratching, rocking, chewing on themselves, and other repetitive and self-stimulating behaviors. One gorilla spun in tight, fast circles. Another bobbed her head up and down.”42
