As anthropogenic influences on climate change become more readily apparent, the role of behavioral science in understanding barriers to sustainable actions cannot be overstated. Environmental psychologists have proposed that a major barrier to sustainability is the delayed, socially distant, and probabilistic effects of public policy efforts aimed at preserving Earth’s resources. This proposal places sustainability squarely within the research topic of delay, social, and probability discounting – processes well known to behavioral scientists. To date, there has been surprisingly little behavioral research examining the role of discounting processes in environmental decision making. In the present study, we examined the degree …

Previously, we (McKerchar et al., 2009) showed that two-parameter hyperboloid models (Green and Myerson, 2004; Rachlin, 2006) provide significantly better fits to delay discounting data than simple, one-parameter hyperbolic and exponential models. Here, we extend this effort by comparing fits of the two-parameter hyperboloid models to data from a larger sample of participants (N= 171) who discounted probabilistic as well as delayed rewards. In particular, we examined the effects of amount on the exponents in the two hyperboloid models of delay and probability discounting in order to evaluate key theoretical predictions of the standard psychophysical scaling interpretation of these exponents. …
