Experimental economics is bothered with utilizing laboratory experiments to realize understanding of how cognition, memory, and heuristics have an effect on behavior of individuals in an economic setting. Such experiments are sometimes motivated by theory validation, policy framing, or institutional/market style issues. Usually, experimental subjects are asked to form variety of choices in a very controlled laboratory setting. Often, the "games" these subjects play are interactive - how well one will depends on the choices of different subjects - closely resembling real economic things. Evolutionary learning models are usually used to elucidate the information.
