Abstract
Every action demands some effort, and its level influences decision making. Existing data suggest that in some decision contexts, effort devalues outcomes, but in other contexts, effort enhances outcome valuation. Here, we describe an empirical study and propose a model that incorporates negative, positive, and mixed impacts of effort on outcomes in different decision contexts and different participants. Participants chose between money and an item associated with varying levels of stair-climbing effort. Some participants had previous direct experience with a real physical effort and made decisions about a physically present reward. For other participants, the effort and the associated reward were always purely hypothetical. Furthermore, the decisions were framed as prospective or retrospective-before or after effort exertion. The key behavioral finding was that in the "real" condition, greater effort decreased outcome value when considered prospectively, but increased outcome value when considered retrospectively. Interestingly, even within the same decision context, individuals showed diverse relationships between effort and outcome value. These relationships ranged from those where greater effort increased value and decreased value to nonlinear patterns, where small effort initially increased outcome value but higher effort decreased it, or the other way around (initial decrease followed by a decrease). When our model was applied to participants' individual choices, it was able to capture the monotonic and nonmonotonic relationships and outperformed previous solutions.

期刊介绍:
The Journal of Experimental Psychology: General publishes articles describing empirical work that bridges the traditional interests of two or more communities of psychology. The work may touch on issues dealt with in JEP: Learning, Memory, and Cognition, JEP: Human Perception and Performance, JEP: Animal Behavior Processes, or JEP: Applied, but may also concern issues in other subdisciplines of psychology, including social processes, developmental processes, psychopathology, neuroscience, or computational modeling. Articles in JEP: General may be longer than the usual journal publication if necessary, but shorter articles that bridge subdisciplines will also be considered.
