Figure 6. Example of the stimuli and the results for Experiment 3.
(A) Orientated isosceles triangles used in the current experiment. (B) and (C) The accuracy and reaction times for the three irrelevant change conditions while triangle's orientation kept constant, respectively. The * and ns show the result of planned contrast between the three types of change and no change. * means the difference is significant, whereas ns means the difference is nonsignificant. (D) The ERPs recorded at FZ and FCZ. Total change elicited N270 relative to no change, whereas no difference existed between conjunction change and no change.
