Guidelines/Instructions

Measure the interaction between accuracy (percentage correct) and speed (reaction time) in seconds on the Symbol Match Test. This score was not developed to make return to play decisions, but can be helpful in determining the extent to which the athlete tried to work very fast on symbol match (decreasing accuracy) or attempted to improve their accuracy by taking a more deliberate and slow approach (jeopardizing speed). The range of scores is from approximately zero to approximately .70 with a mean of .34. A higher score indicates that the athlete did well on both the speed and memory domains of the symbol match test. A low score (below .20) means that they performed poorly on both the speed and accuracy component. If the score is a negative number, the test taker performed very poorly on the reaction time component. Calculated as follows CEI = (1-(ImPACTSymbMatchVisAvgCorrRTDur/3)) * (ImPACTSymbMatchHidTotCorrNum/9).
