a
Win accuracy following a 10%, 30%, 50%, 70%, or 90% selection.
b
No win accuracy following a 10%, 30%, or 50% selection (70% and 90% were not included in behavioral or imaging analyses due to expectancy violations).
c
Win reaction time following a 10%, 30%, 50%, 70%, or 90% selection.
d
No Win reaction time following a 10%, 30%, or 50% selection (70% and 90% were not included in behavioral or imaging analyses due to expectancy violations).
