unanswered questions to spark interest

is it only me or do other people listen to certain songs because it also gives them a feeling or an emotion?  different music elicit different types of emotions.  perhaps it's a generational thing, but i bet some older people listen to oldies to feel the nostalgia of their younger years.  should do a multi-generational survey about music and emotions.

if language is performance and we are all performing our identities and roles all the time...then why do we enjoy watching other people play different people in movies and such.  we are actors too and our friends as well.  why do we love movies so much?  does watching a movie elicit different emotions then reading the novel?

we talked about code-switching for bilinguals but how about code-switching for multi-linguals (polyglots)?  if you get people that can speak 3 or more languages together, then which language will they decide to use?  of course language proficiency plays an important role in deciding which language they will use, but it would be worth seeing which languages people use for which situations.

what if we analyzed the errors that bilinguals make when they speak two very similar languages such as korean and japanese, vietnamese and cantonese, spanish and portuguese, english and german, or french and italian? are they more likely to mix languages or more commonly make lexical errors than people who speak more different languages such as swahili and arabic or english and chinese?
