One‐way ANOVAs evaluating main effects of radius (r = 20, 25, 30, and 35 mm) within each age group in each region
| Brain region | 8–12 years | 13–15 years | 16–19 years | |||
|---|---|---|---|---|---|---|
| Left F 3,20/P | Right F 3,20/P | Left F 3,35/P | Right F 3,35/P | Left F 3,40/P | Right F 3,39/P | |
| Frontal | 9.1/<0.001 | 11.5/<0.001 | 7.7/0.0004 | 8.1/0.0003 | 6.5/0.001 | 10.9/<0.001 |
| Parietal | 11.3/<0.001 | 6.4/0.003 | 5.8/0.002 | 10.0/<0.001 | 6.5/0.001 | 11.8/<0.001 |
| Temporal | 6.6/0.003 | 9.3/<0.001 | 6.9/0.001 | 9.96/<0.001 | 7.4/0.0005 | 19.8/<0.001 |
| Medial Temporal | 0.06/0.98 | 0.3/0.8 | 0.23/0.9 | 1.6/0.2 | 0.3/0.8 | 0.2/0.9 |
| Occipital | 1.8/0.2 | 1.0/0.4 | 0.13/0.9 | 2.1/0.1 | 0.49/0.7 | 0.5/0.7 |
| Cingulate | 1.5/0.3 | 0.76/0.5 | 0.98/0.4 | 1.3/0.3 | 2.3/0.1 | 2.1/0.1 |
Note that the effect of the choice of radius using the approach Schaer et al. (2008) is highly significant for most cortical regions. This shows that this approach to measure GI is less stable.
