Group averaged Day-1 (panels A, B, and C) and Day 2 (panels D, E, and F) aEA, |aY|, and aYϕ for both pass and refer groups. Shaded areas denote the IQRs. (Pass = light gray shading; Refer = dark gray shading; where there is IQR overlap, the dark gray shading can been seen “behind” the light gray shading). Black lines, solid and dashed, represent the 50th percentile for the DP1-Pass and DP1-Refer groups respectively.
