Facial Feedback Theory?Student needs help

Looking for information on, facial feedback theory and script/affect theory. I believe these were both put forth by S.S.Tomkins, though I'm not sure. What I need is a simple (please, remember, first year student) definition of these two theories and whatever correlation there is. My paper topic is how our body-language and/or facial expressions can influence our interaction with others, regardless of what we communicate verbally. Thank you for any help offered. Patricia
