Elevated physiological arousal is associated with larger but more variable neural responses to small acoustic change in children during a passive auditory attention task.

A marginally non-significant bivariate relationship was identified when comparing between-trial variance in N250 peak amplitude and N250 amplitude, suggesting that participants with greater between-trial variance in N250 amplitude showed lower average N250 peak amplitude responses ρ(20) = .42, p = .067 ( Fig. 3 b).
