I'm trying to figure out what degree you're pursuing. I'm guessing psychology but then you said you had a math test. Unless its stats then it makes sense. Am I wrong?
Oh as for your paper, you could add voice quality. Pitch, volume, rhythm and rate of speech. You could even write about clothing. What kind clothes you wear could convey your intentions and personality and in turn affect the interaction you have with other people.
I'm majoring in Communication Sciences and Disorders with emphasis in Speech Language Pathology. I have to take math as part of my general education. I still have a few extra classes like that to pick off before I get to move into the higher level courses in my field. It's unfortunate, but at least I'm almost done.
That's a great suggestion! I'll incorporate that into my brainstorm. I have such a hard time writing papers because I'm indecisive about what I want to say, but that really helps!
