We offer an evolutionary model of the emergence of concepts of salience through similarity-based learning. When an individual faces a new decision problem, she chooses an action that she perceives as similar to actions that, when chosen in similar previous problems, led to favourable outcomes....

In this experiment, individuals recurrently play coordination games that are similar to, but not identical with, one another. Initially, subjects are no more successful than if they had acted at random, but coordination rates gradually increase to levels similar to those found in one-shot games...
