yeah, that's the kind of stuff they're looking for. i also researched some stuff generally on form and writing, since i didn't write a particular genre. so i looked at a huge amount of short stories, and analysed them in my journal like i would for any english text, and also i wrote down whether or not they sucked, so that going back you can see what makes a good short story, and what elements are important and what you can be flexible with. i also looked at poetry for the writing styles and the imagery that it uses, but depending on your audience and the style of writing that you'd be using, that's not really necessary.
as well as all that, as jellymonsta said, they love your own experience. so you mention how you drew on dreams, or your relationship with your little sister, or a guy that you bumped into in the street when you were seven. different mediums are good - i stuck amelie and lantana leaflet things in my journal, because i liked the colours, and ended up justifying them as examples of great characterisation, which my teacher liked. i used newspaper articles about various people, and again called it characterisation research. anything - advertisements for movies, conversations with your grandma. oh, and i think you can also do research on how writers write. we had peter skrzynecki come to our school to give a lecture on his poems, and he ended up talking to the 4u people too about writing and stuff, so i stuck that in. basically, anything you see that you can connect to your story. lots of the links sound kind of tenuous now, but you'd be surprised at the things that end up influencing you. they just basically want you to seek them out and identify them.
