Caveats on these fits (2 terms)

Each tag below is attached to one or more candidate fits for this finding. The chip column in the table flags which row carries which tag.

accuracy-summary fit
Fit is a descriptive p(correct)-by-strength model over accuracy summaries, not a signed-choice or reaction-time model.
figure/source data
Fit is based on paper figure source data or summarized values, not a full public trial table.
