Pigeons show same-different conceptualization after training with complex visual stimuli.

چکیده
Eight pigeons were first trained to peck 1 button in the presence of 16 distinct 4 x 4 arrays of identical pictures and to peck a 2nd button in the presence of 16 distinct 4 x 4 arrays of nonidentical pictures. Later, they were tested with 16 other same and 16 other different stimulus arrays involving untrained pictures. Performance to the testing arrays greatly exceeded chance levels, thus suggesting same-different conceptualization by pigeons.

Comparative Cognition: Beginning the Second Century of the Study of Animal Intelligence
Concepts One of the empirical hallmarks of conceptualization is the independence of discriminative responding on the specific details of the prevailing stimuli. Thus, it was imperative in work on object concepts to show that discriminative responding established to a set of training stimuli also extended to a set of untrained test stimuli. To have conceptualized chairs requires that new chairs ...
متن کاملOddity of visual patterns conceptualized by pigeons
Pigeons were trained to learn an instrumental oddity-from-sample discrimination involving visual forms. One group, the "few examples" group, dealt with 5 patterns in 40 different combinations. Another group, the "many examples" group, dealt with 20 patterns in 160 different combinations. After both groups had reached asymptotic performance and had learned to operate under partial reinforcement ...
متن کاملPigeons' recognition of partially occluded objects depends on specific training experience.
DiPietro et al (2002 Perception 31 1299-1312) reported a dramatic improvement in pigeons' recognition of partially occluded objects after the birds had been trained to recognize objects that were placed on top of another surface. Here, we investigated whether training with partially erased stimuli or with notched stimuli that had a thin gap between the object and another surface would similarly...
متن کاملAbstract-concept learning carryover effects from the initial training set in pigeons (Columba livia).
Three groups of pigeons were trained in a same/different task with 32, 64, or 1,024 color-picture stimuli. They were tested with novel transfer pictures. The training-testing cycle was repeated with training-set doublings. The 32-item group learned the same/different task as rapidly as a previous 8-item group and transferred better than the 8-item group at the 32-item training set. The 64- and ...
متن کاملVisual artificial grammar learning: comparative research on humans, kea (Nestor notabilis) and pigeons (Columba livia).
Artificial grammar learning (AGL) provides a useful tool for exploring rule learning strategies linked to general purpose pattern perception. To be able to directly compare performance of humans with other species with different memory capacities, we developed an AGL task in the visual domain. Presenting entire visual patterns simultaneously instead of sequentially minimizes the amount of requi...
