Unlocking a new dimension in the speed–accuracy trade-off

K Tsetsos - Trends in Cognitive Sciences, 2023 - cell.com
Why do we sometimes spend too much time on seemingly impossible-to-solve tasks instead
of just moving on? Masís et al. provide a new perspective on the speed–accuracy trade-off …

Pushing the bounds of bounded optimality and rationality

S Musslick, J Masís - Cognitive science, 2023 - Wiley Online Library
All forms of cognition, whether natural or artificial, are subject to constraints of their

Decision bias and sampling asymmetry in reward-guided learning

Y Cao, K Tsetsos - bioRxiv, 2023 - biorxiv.org
Human economic decisions are highly sensitive to contexts. Deciding between two
competing alternatives can be notoriously biased by their overall value ('magnitude effect') …
