A part of Fe is "reading emotional data" right? Picking up on signals from others that indicate what they are feeling right?

So if I were to ask some Fe base types and some Fe PoLR types to watch a short film and write down the number of times they picked up on an indication of what the person in the film was feeling, would it be an adequate way to test the Fe difference between Fe base types and Fe PoLR types? Yes or no and why?

Thanks for your replies.
