Say hi to Halley. Do lemurs perceive the world as we do? Can they perceive colors? If so, what colors do they "see"? What do you think? Part of my research is understanding lemur vision and perception, specifically with the ruffed lemurs (genus Varecia).

Decisions. Decisions. These ruffed lemurs are trained to target a red square and then given two-choice discrimination tasks. Aptly named, the lemurs have two choices (stimuli) and they have to discriminate one over another (one gives food reward, and the other doesn't). Here, you see Halley doing her two-choice discrimination task and has to make a decision. What do you think? Do you think Halley "gets it"? Do you think she will touch the red square over the gray square? Will there be craisins in the horizon ...?

Here's a short clip of Halley doing a two-choice discrimination task. I posted a photo earlier of her contemplating which square to touch. Watch her solve the task. Please Like and Comment below. Tag your friends if you think they like lemurs!
