Abstract

A current aim in research on moral cognition is the development of computational models of moral choices and judgements. We fit diffusion models with and without dependence on visual fixations to data on binary moral choices. We find that a fixation dependent model provides a better fit and can capture many features of the empirical data. We discuss the implications for understanding moral cognition and future development of moral choice models.
