Figure 8
The Lateralized Readiness Potential (LRP). LRP curves are represented by solid lines where the LRP significantly deviated from zero. The dotted arrows show the opposite polarity of the LRP in children relative to adults in the neutral and congruent conditions. The solid arrow shows the incorrect response tendency signalled the LRP in the incongruent condition of numerical comparison. The red horizontal markers denote significant differences between LRPs in the neutral vs. incongruent conditions. The timing of the first EEG distance effects is represented by thick horizontal markers at the time axes. The reaction time is marked above the LRP curves ("RT"). The long vertical marker denotes the reaction time in the neutral condition; the shorter markers denote the reaction time in the congruent (earlier) and incongruent (later) conditions.
