These key words are underlined in the score sheets. Each key word repeated correctly is one point. Subtract the total correct from each list from 23.5 to get the SNR-50; this is the signal-to-noise ratio for 50% correct. The next step is to average the SNR-50 scores for both lists of the list pair, then average the list pair scores. Finally, compare the list pair score to the age-related norm to determine the SNR loss.
