You'll probably want aversive.stimulus in there as well:

+ geom_point(aes(colour = "Aversive Stimulus", x=aversive.stimulus))

The reason why Emilio's first attempt didn't work is that I have
removed the add argument from qplot because it is no longer necessary
- I might not have removed it from the documentation yet though,
sorry!
