The aim of the present study was to investigate the effect of enhanced
motivation on feedback processing during learning. To achieve
this end, we performed two experiments. In the first, we tested a motivational
interviewing manipulation that could increase motivation (or
attenuate natural decreases in motivation) across two sessions of a
learning task. In the second, we capitalized on the motivational variability
within those who experienced the motivational interviewing manipulation
and used fMRI to explore neural differences associated with
varying motivation levels before and after the interview. In both experiments,
participants completed two separate sessions of a feedbackbased
word association learning task. Changes in their motivation for
each session were used to investigate motivational effects on learning
and feedback processing
