Comparative Cognition of Object Recognition

Object recognition is fundamental in the lives of most animals. The authors review research comparing object recognition in pigeons and humans. One series of studies investigated recognition of previously learned objects seen in novel depth rotations, including the influence of a single distinctive object part and whether the novel view was close to two or only one of the training views. Another series of studies investigated whether recognition of directly viewed objects differs from recognition of objects viewed in pictures. The final series of studies investigated the role of motion in object recognition. The authors review similarities and differences in object recognition between humans and pigeons. They also discuss future directions for comparative investigations of object recognition.
