A trial began with a 0–100 ms jittered fixation-cross. An eyetracking
trigger then required fixation on the cross for 250 ms before
the stimulus was presented for 250 ms. A white response-screen
was then presented for 900 ms. There were 8 blocks of 260 stimuli
(10 pictures per condition × 26 conditions). This resulted in a total
of 80 trials per condition (2080 trials total).
