Bridging Species Differences in Rule Switching: How Humans and Monkeys Solve the Same Wisconsin Card Sorting Task

Journal of Neuroscience April 16,2025

Goudar et al. (2024) used a novel, high-dimensional version of the Wisconsin Card Sorting Test and an unsupervised computational model (input–output HMM-GLM) to compare rule-switching strategies in humans and monkeys. They found that while both species employed similar inference strategies, monkeys were slower to adapt, made more errors, and showed less sensitivity to feedback, highlighting both shared and divergent cognitive processes across species
