APA Dictionary of Psychology

a form of social learning in which one or more individuals engaging in some behavior with an object in a particular location draw the attention of another to that location, which facilitates the acquisition of similar behavior by that observer. The attraction of attention to a particular place in the environment, not any specific social interactions among the demonstrators and observer, is what leads to learning. For example, ducks in a pen may ignore an escape hole unless they are near another duck who escapes through the hole, thus drawing their attention to it.
