Abstract:

Results obtained on a group of 446 men given both the standard Radium Plaque Adaptometer test and also the same test at a brightness .20 log units lower than the standard, indicate that a much larger percentage of men will necessarily fail the test if the brightness is lowered. Classification based on a more difficult test has the same statistical properties as that based on the regular test, and consequently will doubtless be no more reliable.
