The award-winning Pixar film "Inside Out" explored five specific human emotions: joy, sadness, anger, fear and disgust. But a recent study concludes we have a lot more than that — somewhere between 25 and 27.

The study had more than 800 men and women watch more than 2,000 “emotionally evocative” short films and measured what they felt. Then they put together a multidimensional, interactive map to display how some of the emotions related to each other.

We spoke with Dacher Keltner, psychology professor at UC-Berkeley, about the study.
