Working memory (N-back) task
Mean reaction times decreased over session [F(2,54) = 4.54, p= 0.015] and increased with level [F(3,81)= 113.09, p < 0.0001], thus replicating the standard N-back effect (19). However, all effects involving migraine group vs. control were far from signi cant [F’s < 1]. Error rates decreased with session [F(2,64)=25.68, p < 0.0001] and decreased with lower levels of dif culty [F(3,96)= 104.46, p < 0.0001]. Reaction times for each session are presented in Table 5.
