I'm designing a study in which 2 participants each write 4 statements about a topic, and then rate each others' statements. (I'm planning to have them swap computers/seats after writing their statements and rate the others'.)

I have 2 questions here:
1) Can I randomize the order that those statements come up for the 2nd participant to rate?
2) Can I actually have all 4 statements come up together? See, participants will be asked to write 2 sincere statements and 2 sarcastic ones, and the rater is supposed to guess the writer's intentions; it would be a different task to have all 4 statements side by side and ask which 2 are sincere and with 2 are sarcastic than to have 1 statement come up at a time and ask whether it's sarcastic or sincere and then go to the next one.

I know that one can put custom items into MediaLab, but unfortunately I have no programming experience...
Thank you.
