I am going to create an aggression index to find out the aggressiveness of a male. For one hour, I will show a male his reflection in a mirror, and will time how long it takes him to flare at it. Then I will take it out for 2 minutes and repeat for 30 trials, or until the male becomes used to the reflection ( does not flare for 1 minute of exposure). I will use this formula: a= 1- (avg. time until flare / # of responses until habituation). I think that will work, if it does not, I will have to change the formula a bit.
