Primary Outcome Measures

Name	Time	Method
<p>The primary study parameter in the current study is the error in size<br /><br>estimation of the size of the abdomen before and after providing multisensory<br /><br>input. By subtracting these two scores a difference score emerges. This allows<br /><br>for testing whether size estimation changed from pre to post multisensory<br /><br>input, and whether AN patients and healthy controls differ on this variable. In<br /><br>addition, participants will also estimate the size of control body parts<br /><br>(shoulders, hips, height), we do not expect any differences in size estimation<br /><br>error from pre to post multisensory stimulation. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The first secondary study parameter is again the difference in size estimation<br /><br>error from pre to post multisensory stimulation. However, not only group<br /><br>differences will be assessed, we will also investigate whether size estimation<br /><br>errors differ between synchronous and asynchronous multisensory stimulation.<br /><br>Based on our previous study we do not expect differences between providing<br /><br>multisensory input synchronously compared to asynchronously.<br /><br>The second secondary study parameter is the error in size estimation during the<br /><br>follow up measurement. This follow up error can be compared to pre and post<br /><br>size estimation errors. This will indicate whether within either group the<br /><br>change in body size experience after multisensory input is persistent over<br /><br>time. </p><br>
