2X2X2 design.. what statistics should I use?


I am doing a research with a 2X2X2 design:
Between subjects (Positive Mood VS Negative Mood)
Within subjects (Positive Stimuli 1 VS Negative Stimuli 2)
Within subjects (Positive Stimuli 2 VS Negative Stimuli 2)

I have a range of dependent variables including response time/ decision time/ type of decision made...etc.

Should I use a ANCOVA, or is a factorial ANOVA just fine.

Thank you very much! :):):)
