A Multi-task Platform for Profiling Cognitive and Motivational Constructs in Humans and Nonhuman Primates

This paper introduces a multi-task software platform for assessing cognitive and motivational functions in humans and nonhuman primates, demonstrating its use in testing NHPs on multiple tasks and extracting performance metrics.

Dose-dependent dissociation of pro-cognitive effects of donepezil on attention and cognitive flexibility in rhesus monkeys

This study shows that different doses of donepezil affect attention and cognitive flexibility differently in rhesus monkeys, with higher doses improving attention but not flexibility.

A Kiosk Station for the Assessment of Multiple Cognitive Domains and Enrichment of Monkeys

This paper introduces a Kiosk Station for running cognitive tasks in cage-housed monkeys, showing high engagement and consistency in cognitive performance.

Learning at variable attentional load requires cooperation between working memory, meta-learning and attention-augmented reinforcement learning

The paper shows how working memory, meta-learning, and attention-augmented reinforcement learning cooperate at different attentional loads to enable flexible learning in rhesus monkeys.

Gains and Losses Affect Learning Differentially at Low and High Attentional Load

This study investigates how prospective gains and losses affect flexible learning under varying attentional loads, finding that gains improve learning at low loads while losses impair learning, especially at high loads.
