Figure 5. MRGS peak frequency by condition.
Box plots showing the peak frequency for the congruent (left) and incongruent (right) conditions. Frequency (in Hz) is denoted on the y-axis. The center line within each box denotes the median frequency, and the bottom and top of each box designate the first and third quartile, respectively. Each lower and upper stem reflects the minimum and maximum values. The peak frequency of the MRGS response was higher in the incongruent relative to the congruent condition, t(41) = 2.159, p = .037.
