Regurgitation in gorillas: possible model for human eating disorders (rumination/bulimia)

Regurgitation and reingestion behavior in gorillas is compared with two human disorders, rumination and bulimia. Eighty-four percent of captive gorillas that are more than 5 years old regurgitate and reingest. Comparisons are made on the basis of ontogeny, context, motor...
