While testing my hypothesis on motor learning rates, I noticed that while there does appear to be a variance in the slope from person to person, some of the data appears not to make much sense. In particular, one person had a POSITIVE slope in his frontal lobe.
Now, what that essentially means is that this person had to do more and more processing with each repetition of the task. Tasks require less cognitive processing with each repetition; this is how we learn to do things like walk.
So what on earth is a positive slope supposed to signify? 🙂
