First of all, if you don't mind providing some important info -- are you looking to measure the affects of 'the perception of revenge' when subjects view violent attacks?
Since you mentioned getting two clips, one 'initial attack', & one 'revenge attack', I see some immediate experimental design flaws.
The thing is, the students will see one of the attack clips first, which will affect the subjects' viewing of the second clip. The first contaminates the second viewing (desensitization, etc). And/or if you only show one clip to one group, & a different clip to another, you'll create extra variables (such as: one clip had male on female, one's crueler, etc).
You can remove the contamination by only exposing the subjects to the same single violent clip; then before subjects view clip, simply inform subjects of Group A 'it's an unprovoked attack', & to Group B 'it's a revenge attack'. Of course, the clip must be exactly the same to avoid the extra variables that different clips introduce.
And as Ferox asked, how will you be measuring the subjects reactions? A questionnaire, or hooking them up to a bio-sign machine?
