Dynamics of pre- and post-choice behaviour: rats approximate optimal strategy in a discrete-trial decision task

Fam, Justine; Westbrook, Fred; Arabzadeh, Ehsan


We simulate two types of environments to investigate how closely rats approximate optimal foraging. Rats initiated a trial where they chose between two spouts for sucrose, which was delivered at distinct probabilities. The discrete trial procedure used allowed us to observe the relationship between choice proportions, response latencies and obtained rewards. Our results show that rats approximate the optimal strategy across a range of environments that differ in the average probability of...[Show more]
