32/36, but only because it was multiple choice and because I had a static picture that I had all the time in the world to examine and logic through. I have no idea where to start when looking at these; all the women look flirtatious and all the men look neutral except for the second one (the older person with the wrinkles and the triangle eyes), who I can tell looks sad or upset. But with the multiple choice, I can usually rule out three of the emotions because they just don't fit at all.
Most of the pictures are of a person with their face turned away and looking out the side of their eyes, towards the camera. And then they give you options like Ashamed (requires eyes down), Hostile (requires eyes and face straight forward, low eyebrows), Surprised (requires eyes straight forward, high eyebrows), or Thoughtful (the only one left, and even if it wasn't my first reaction, the markers fit).
I really like the show 'Lie to Me', where the main character is basically a human lie detector because he taught himself how to read peoples emotions based on micro expressions. They go into a lot of detail about the specific markers he's picking up on, which emotion they signify, and they use examples from history and media to show different examples of the markers.
