Session 1 Session 2 Session3
Incongruency trials

a

For Incongruency, significant RT reductions were observed between each successive session (all pairwise p<0.05).

b

For Incongruency accuracy and Gratton RT, significant differences were observed between sessions 1 and 2, but not between sessions 2 and 3 (all pairwise p<0.05).

c

For Gratton trials, accuracy was significantly increased from session 1 to 3, but neither session were significantly different from session 2 (p<0.05).
