Figure 2.
Mean RTs (A) and ERs (B) by stimulus congruity condition. Mean RT was found to increase with stimulus incongruity (CON < INCLO < INCMED < INCHI; p < .001 for all comparisons). Mean ER also increased with stimulus incongruity (CON < INCLO < INCMED < INCHI) with CON versus INCLO and INCMED versus INCHI comparisons reaching significance (p < .001) and INCLO versus INCMED approaching significance at p = .113.
