They are different, forget about significance. > How can I do that? You don't. Your problem translates to whether reward or punishment gives a better learning curve, so you build a model using a factor that represents whether the learning curve comes from reward or punishment, and test the significance of the difference using the correct approach in the framework of your choice. And since curves are functions, you actually need a method for functional data analysis. Either you start eg here : http://www.psych.mcgill.ca/misc/fda/ or you take the advice of Bert. If I was you, I'd go for the latter. > Thank you. You're welcome.
