Ambiguity preferences in intertemporal and risky choice: A large-scale study using drift-diffusion modelling.

ABSTRACT: Intertemporal choices constitute a significant topic of interest in both psychological and behavioral-economics research. While many studies focus on decisions with precisely known reward delivery times, real-world situations typically involve only an imprecise knowledge of these timings (i.e., the delivery times are ambiguous). The current study uses a large size dataset (sample size N > 669) consisting of both risky and intertemporal ambiguous and nonambiguous choices and aims (i) to clarify the relationship between probability-ambiguity and time-ambiguity effects on choice, and (ii) to evaluate different computational models (attribute-wise and integrated-value models) across risky and intertemporal choice domains using a drift-diffusion model (DDM) framework. Analysis of the choice dat
