Oh I like this one, and I'm going to contribute with somethings I know from my researches in behaviors, although i don't really know much on psychology. I would love to know how to be able to manipulate audiences and people, but unfortunately it takes some natural talent(leaned at childhood) and allot of practice, which requires you to try and lie to everybody, allot, but if you have imagination, I think you can practice by yourself and reach some good results.
I have some of the works I've read in my computer and try to sum up the best ones in here. Alright then, there are 4 ways to communicate with other people, Verbal and Non-Verbal (Facial expressions, Body Language and the last one i don't quite remember the name but it has to do with uncontrollable body actions, like sweating). For the verbal part I don't really know anything, but the pitches of the voice and stuff like that also fall under the Non-Verbal category, although not very refereed.
For the Non-Verbal, I have quite a collection.
Lets start with the first one, Facial expressions, I suggest you read "Emotions Revealed" by Paul Eckman, the guy who inspired and was the base for the creation of the series "Lie to me*", the book basically divides the wide spectrum of emotions in to 6 categories (a 7th is under research but still not conclusive) of "pure" emotions: sadness, anger, fear, surprise, happiness, disgust, the seventh is contempt but is described in disgust. In each of those emotions, he goes into describing the cause for each and the related facial expressions, from mild to extreme. I suggest you take a look at these and train in picking them up from other people, specially the mild ones. Oh and the author suggests a way to train emotions quite simple and fascinating, it is proved that if you imitate a facial expression, you will feel the emotion, specially if you are imitating an extreme from another person, this can help you allot in representing the 6 different emotions truthfully.
For Body Language, I don't have any specific one to suggest, but just get one that has allot of pictures, trust me, they will illustrate each case quite nicely. This ones will explain the meaning of each position you take, each hand movement, each way you put your arms or legs, anything that concerns your body actions. If you haven't heard about Body Language, i suggest it would be the first thing you search! Seriously, you will be overwhelmed by the amount of information you can learn from it!!! You should see it and practice trying to decipher other people! Quick spoiler: when a person talks to you with their hands open, this reveals... openness, that he is not hiding anything, that he is opened to suggestions and ideas from the outside, just like a dog exhibits their neck, a very vulnerable part.
On the last part, the uncontrollable body actions, I've only seen a vague reference to them in some articles and books, since they are still under heavy research. But mainly they reveal your past actions or some emotions you are having, and the most obvious of them all can be controlled with confidence and a tissue eh eh.
I also advice you to read one or other book about public speech, which I haven't read yet. Don't really expect to learn much in books about manipulation, I have read one, and it doesn't talk much about manipulating an audience, but it talked about marketing tricks and some of them might come useful one day or another. It all depends on what you really want to specialize.
Oh and a tip, actors and the best liars don't really fake emotions, they actually sum them up, normally by their past memories, thats why you can't even tell if they are faking it or not, because in a certain way, they are not!
Anyway, tell me if you find anything interesting
btw: sorry for the terrible writing, i got carried away and gave it a quick spell check
