| B | Beta | t | p | ΔR2 | |
|---|---|---|---|---|---|
| Step 1 | .097 | ||||
| Age group | − .2.56 | − .312 | − 3.02 | .003 | |
| Step 2 | .138 | ||||
| Age group | − 3.60 | − .438 | − 3.18 | .002 | |
| Matrices | 0.46 | .199 | 1.70 | .092 | |
| Processing speed | − 1.45 | − .357 | − 2.48 | .015 | |
| Working memory | 0.58 | .243 | 2.22 | .029 |
ΔR2 represents the additional variance counted for by all the variables in a step. Regression statistics given with relevant variables at a step in the prediction equation. Age group was treated as a dichotomous variable (young vs. older adults) in the regression.
