The impact of the certainty context on the process of choice.

@article{citeulike:100372, abstract = {In this study we examine how the introduction of a reference lottery with nonrandom outcomes alters the way in which choices among pairs of lotteries are made, even if it does not alter the choices.

In our experiment, the change from gain to loss domain affects choices: subjects are risk averse in the gain domain, but not in the loss domain.
