Figure 1From: Neighborhood consistency in mental arithmetic: Behavioral and ERP evidenceGrand average ERPs with short (150 ms) SOA presentation. On the right-hand side, the grand average ERP of electrode PZ is zoomed in for better readability. Stimulus onset of the probe is represented by the vertical microvolt calibration bar. Grand average curves are baseline-corrected in the time window 100 ms before stimulus onset. Note that negative voltages are plotted in the upward direction. Numbers in brackets are examples for probes presented after the problem 8 × 4. rel = related; unrel = unrelated; cons = decade-consistent; incons = inconsistent.Back to article page
