Healthy children and adolescents (8 to 18 year olds)

Exclusion Criteria

Children and adolescents cannot participate in the proposed MRI-experiment if one of the following applies:
1) Metal parts, that cannot be removed, are present in or on the upper part of the body (e.g. plates, screws, aneurysm clips, metal splinters, piercings or medical plasters).
2) The participant has an active implant, such as a pacemaker, insulin pump, neurostimulator and/or ossicle prosthesis.
3) Head surgery has been performed.
4) The participant suffers from epilepsy.

Primary Outcome Measures

Name	Time	Method
<p>In the proposed study, brain activation patterns are the dependent variables.<br /><br>We are interested in the neural correlates of landmarks with different<br /><br>navigational relevance. More specifically, we would like to investigate how<br /><br>they change with age. Moreover, we would like to investigate whether more adult<br /><br>like brain activation patters are associated with better performance on the<br /><br>navigation task.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>In addition we are interested in behavioral measures such as response times and<br /><br>percentage of errors.<br /><br>We will also include measurements of IQ and emotional status to describe our<br /><br>study population. If the scores of a subject deviate from the mean more than 2<br /><br>standard deviations, the experimental scores will not be included in further<br /><br>analysis. </p><br>
