Pigeon’s recognition of cartoons: effects of fragmentation, scrambling, and deletion of elements

摘要: J. Cerella [Pattern Recognit. 12 (1980) 1] and more recently S. Watanabe [Behav. Proc. 53 (2001) 3] demonstrated that pigeons showed no decrement in recognizing cartoons were spatially scrambled, indicating pigeons' discriminative responding is controlled by local features alone. In contrast Kirkpatrick-Steger et al. [J. Exp. Psychol. Anim. Behav. 24 (1998) 34] used line drawings as stimuli the importance of spatial organization for picture recognition pigeons, confirming related findings reported their previous studies. The present study revisited pigeons. Experiment 1, trained to discriminate cartoon people on a variety background scenes. Subsequent tests revealed performances with both familiar novel instances decreased objects object-like parts progressively fragmented, search targeted stimulus array might have enhanced attend global aspects people. 2 faces examined effects scrambling deletion components. A set components (eyes eyebrows) exerted strong control over behavior only moderately suppressed responding. results suggest use aspects, different mixtures these types information depending particular perceptual context.
