A dynamic systems and network model of talent and excellence across the lifespan Paul van Geert, Henderien Steenbeek and Marijn van Dijk		Distinguishing and Improving Mouse Behavior in ASD and ADHD children Baukje Veenstra, Paul van Geert and Bieuwe van der Meulen
For this version of the model, you must have an add-in for Excel installed, called Poptools, which is freely downloadable from the website http://www.poptools.org/ Note that the add-in has been written for 32-bit PC versions of Microsoft Excel. For 64-bit PC versions, a new version of this model will be posted soon. I don't know if the visual basic macro will work on the Mac.		Supporting Materials
Excel model for Excel 2010 and 2007 (32 bits)
If you open the file, do not forget to enable all macros and enable all links. After enabling the links, click Continue. If you still have problems with links, click the POptools menu in the Add-Ins menu of Excel, then click Update Poptools links.
