Why learn? The adaptive value of associative learning in wild populations

The ability to associatively learn is highly conserved, having been evidenced in all bilateral animals tested to date. This general cognitive process has been shown to play a role in a wide diversity of behaviours, including interactions with predators, prey, rivals and mates. Learning is thus expected to be essential for survival and reproduction in many species, but because of associated costs, it is also predicted to be fine-tuned to...
