In any case, I am highly skeptical that emotions can be measured by physical reactions.

Using physical reactions to measure emotions has a long history. It's the basis of things like lie detectors. When people are sad, they cry. When they are happy, they laugh or smile. When they are frightened, their heart speeds up. When they are angry, they frown or become red faced. The blush is an involuntary physical reaction to embarrassment. While I'm sure that not everyone's physical reactions are precisely the same for a given emotion and it's certainly possible to repress physical reactions, being able to do so is not very common.
