Corrected a couple of spelling errors and clarified the meaning of the sentence (hopefully).

comment Are motivation and efficiency inversely correlated?
It seems that you are using anecdotal evidence to back up the claim that motivation and efficiency are inversely related and then ask for the reasons. But it's not that clear that the claim is true in the first place. Before one can look for reasons there must be some confidence in the relationship which I don't think there is.

comment Fitting a psychometric function when data does not lend itself to a sigmoidal fit
What exactly is the plot showing? Is it data from a single participant or data for an item? Since there are no lables for the axes, what is plotted on the x- and y-axis? It looks like the y-axis could be the probability for getting the right answer since it goes from 0 to 1. Is that correct?

This is interesting. Can you give some insights into your experiments?

comment Do we need a pre-test to compare the effectiveness of two treatments?
I would emphasize that while random assignment is in theory sufficient (as Jeromy already noted), in reality it is very hard to obtain random samples. E.G. you can't randomly assign students to a class. And even if you did, from that point on they are all in the same class and measures are not independent anymore. Hierarchical models were developed with this application in mind, but they are suited for a variety of contexts. So maybe this might be an option.
