Note: The overall R² reports the proportion of total item variance accounted for by fixed effect factors effects (items, repetition, concreteness, and random intercepts—individual differences in mean FOKs). The fixed-effects R² is the proportion of total item variance accounted for by the fixed effect factors, ignoring intercept variance.
