AAT Approach Avoidance Task, GNG Go/No-Go, IAT Implicit Association Task, SST Stop Signal Task

For the AAT, split-half Pearson correlations are shown, while for the other tasks, split-half Spearman-Brown-adjusted Pearson correlations are shown. The column Coef contains the value of the coefficient, while the column % shows the percentile of this value in the cumulative empirical distribution of non-stratified permutated coefficients. Below each coefficient obtained via resampled splitting, the 95% HDI is shown in italics. Coefficients that could not be calculated are left empty, while coefficients of splitting methods that are equivalent to the splitting method above them are indicated by dashed lines (--)
