- Primary Outcome Measures
Name Time Method <p>Outcome of the study: The leading theory predicts a positive correlation<br /><br>between strength of lateralization and dual task efficiency and a negative<br /><br>correlation with CC-size, for subjects classified as contra-lateral.<br /><br><br /><br>Primary study parameters: The blood flow velocity in the middle cerebral artery<br /><br>of both hemispheres is measured with fTCD during a single language task and a<br /><br>single visuospatial task. This way, pattern and strength of cerebral<br /><br>lateralization in the subjects can be assessed. The relationship between<br /><br>pattern and strength of lateralization and dual-task performance.</p><br>
- Secondary Outcome Measures
Name Time Method <p>Secondary study parameters: The size of the corpus callosum is measured with<br /><br>MRI and will be related to dual-task performance and pattern and strength of<br /><br>lateralization.</p><br>
