Table 3. Results of the Hierarchical Regression in Which Model 1 Predicts WMC Using Performance From the No Distraction Condition, and Model 2 Predicts WMC Using Performance From No Distraction Condition Together With Both the Encoding Distraction and Delay Distraction Conditions.
| Study | Model | Predictor | R2 change | Standardized beta | p value | Partial correlation |
|---|---|---|---|---|---|---|
| Note. The results of partial correlations are also shown for each of the predictors in Model 2, showing the extent to which they correlate with WMC, whilst controlling for the other two predictor variables. | ||||||
