Discrimination of contour-deleted images in baboons (Papio papio) and chimpanzees (Pan troglodytes).

abstract：:This study describes how three individual fish, Atlantic cod (Gadus morhua L.), developed a novel behaviour and learnt to use a dorsally attached external tag to activate a self-feeder. This behaviour was repeated up to several hundred times, and over time these fish fine-tuned the behaviour and made a series of goal-...
