Note: S1v2 represents the contrast code for membership in study 1 versus study 2 and S12v3 and S123v4 represents those for studies 1 and 2 versus 3 and studies 1–3 versus 4, respectively. Entries are squared semi-partial correlations for each predictor (unique variance explained by that effect), except for rows labeled Model R2, which report the multiple squared correlation for each model (variance explained by the set of predictors). Note that
*
indicates significant at p<.05;

<.01; and

<.001.
