Subject Motivation and Psychophysical Thresholds

Has anyone attempted to determine if a subject's basic discrimination thresholds can be manipulated by their level of motivation?

I think many people assume, for good reason, that lack of motivation will lead to worse thresholds. Subjects who fall asleep during sessions are often excluded from analysis. I am interested in the effect of positive motivation. Does anyone have an empirical reason to think that thresholds for a given [awake] individual would be lower if an additional monetary reward was offered for good performance?
