ImPACT Normative Extension

Study Overview
=================
Brief Summary
-----------------
The researchers want to find out more about a standalone software application, ImPACT Online and how it relates to other commonly used tests of memory, attention and reaction time. ImPACT Online is a computer-based neurocognitive test for concussion management. The test was designed to help measure the effects of concussion on cognitive processes (for example, memory, attention, brain speed) and visual functioning.
