Fig. 2.

Reproducibility, stability, and vector norm for object trials. Across-trial and within-trial dva and spatial L2 norm, for noncontrol (object) trials, are shown both with (left column) and without (right column) mean matching. (A) Across-trial directional variance (1 – reproducibility) as a function of time for unseen (gray) and seen (black) target-present trials. Stars at the bottom of each panel mark time points where the difference unseen – seen is significantly greater than chance (gray, P < 0.05; black, P < 0.01, both corrected for temporal nonindependence using a cluster-based permutation test). (C) Within-trial directional variance (1 – stability). (E) L2 norm of the mean vector within the sliding window. (B, D, and F) Same as A, C, and E after performing the mean-matching procedure (1) on the L2 norm. Analyses were performed using a 100-ms sliding window.
