The recognition of others’ behavior is vital for all animal species, including the highly mobile pigeon (Columba livia). Previous research shows that pigeons can discriminate behaviors using single static poses and smooth motion pose sequences. We investigated whether pigeons use perceptual or mnemonic mechanisms during this discrimination. Three pigeons were tested using a go no-go task in which ... read morethe birds were presented with either single poses or multiple stationary poses of two distinct behaviors. After determining that the birds were using momentarily available perceptual cues, we started training to promote the use of mnemonic mechanisms. After this training, perceptual features were still found to be vital for the pigeons’ discrimination, suggesting that these features are more accessible than the memory of recently viewed poses. Comparisons to theories of action recognition in humans will be discussed.read less
