Design outcomes

Primary

Measure	Time frame
Outcome of the study: The leading theory predicts a positive correlation between strength of lateralization and dual task efficiency and a negative correlation with CC-size, for subjects classified as contra-lateral. Primary study parameters: The blood flow velocity in the middle cerebral artery of both hemispheres is measured with fTCD during a single language task and a single visuospatial task. This way, pattern and strength of cerebral lateralization in the subjects can be assessed. The relationship between pattern and strength of lateralization and dual-task performance.	—
