We report an experimental test of the influence of ambiguity on behaviour in a coordination game. We study the behaviour of subjects in the presence of ambiguity and attempt to determine whether they prefer to choose an ambiguity safe option. We fi?nd that this strategy, which is not played in either Nash equilibrium or iterated dominance equilibrium, is indeed chosen quite frequently. This provides evidence that ambiguity aversion infl?uences behaviour in games. While the behaviour of the Row Player is consistent with randomising between her strategies, the Column Player shows a marked preference for avoiding ambiguity and choosing his ambiguity-safe strategy.

	Experimental evidence suggests that the frequency with which individuals get feedback information on their investments has an effect on risk-taking behavior. In particular, when they are given information sufficiently often, they take fewer risks compared with a situation in which they are informed less frequently. In this paper we find that this result still holds when subjects do not know the probabilities of the lotteries they are betting upon. We also detect significant gender effects, in that the frequency with which information is disclosed mostly affects men’s betting behavior, rather than women’s, and that men are much more risk-seeking after experiencing a loss.
