We tested capuchins, macaques and orang-utans in a food-gambling task to investigate whether or not individuals estimate the chances of...</para>

This chapter provides a critical review of the theories of decision making under risk and under uncertainty and the notion of choice-based subjective probabilities. It includes formal statements and discussions of the various models, including their analytical frameworks, the corresponding...

We examine the nature of stated subjective probabilities in a complex, evolving context in which true event probabilities are not within subjects' explicit information set.
