The paper investigates how stimulus prior and reward probability affect response bias in perceptual decision making using rats, finding that reward ratios have a more significant impact than stimulus presentation ratios.

This paper investigates how stimulus uncertainty and relative reward rates influence adaptive decision-making in rats and pigeons, showing that models incorporating these factors better explain behavior than existing models.

The paper investigates how reinforcement and its omission affect trial-by-trial changes in response bias during perceptual decision-making in rats, finding that a generalized matching law-based model better explains the data than traditional criterion learning models.

The paper investigates how people monitor their voluntary movements by analyzing metacognitive efficiency in different task conditions and movement parameters.

The paper investigates how response-related signals affect confidence and metacognitive performance in perceptual decision tasks, finding no effect of overt vs. covert decisions but increased confidence with motor actions paired to stimuli.
