Location (general brain areas) | Appropriate infant age at testing | Information-processing skills tested | Laboratory measures (cognitive tasks) | |
Orienting network | Parietal lobes | 3ā9 mo | Disengage, shift, refocus | Habituation tasks, looking time tasks, shift rate tasks (32ā34) |
Executive network | Frontal lobes | From 8 mo | Resolution of conflict | A-not-B tasks, problem-solving tasks1 (35, 36) |
Although not previously linked with the executive attention network, problem-solving tasks tap higher-order processes and require voluntary control of attention (12).
