Abstract

Animal and human choices are sensitive to both average and variance of reward. This has been demonstrated separately for several reward dimensions, notably amount of reward and delay between choice and delivery. Of several theories that deal with Risk Sensitivity in biology, psychology and economics, Scalar Utility Theory is special in being grounded in psychophysics and in accounting for more empirical evidence than its alternatives with great economy of parameters, but it has not yet been developed to handle joint effects of more than one dimension of reward. It is proposed to test how joint variability in both amount and delay affects choices, and to test and contrast all prevalent theories of risk sensitivity in animals.
