Table 1.

Both raw and centered group-mean thresholds are reported for each syllable on each task. Centered values are relative to the task mean, facilitating cross-task comparisons. Syllable error terms are within subjects standard deviations (relative to centered thresholds), consistent with the design of the study. Task mean error terms are between subjects standard deviations (relative to raw thresholds).
