So how smart are lemurs, exactly? How do we even start to figure that out? Meet Ray Vagell, researcher and graduate student from Texas State University who uses SMARTA (a custom-designed touch screen system) to study how lemurs solve problems at the Duke Lemur Center. We also discuss the fun – but mysterious – fact that only female ruffed lemurs have color vision. Ray also uses SMARTA to study ruffed lemur vision, and how his research has become enrichment for some ruffed lemurs who love pushing playing with the device. Sometimes they even find ways to cheat the system!
