Base rate of "10 to 11" clocks among patients referred for neuropsychological evaluation.
Of 655 neuropsychological referrals who were asked to draw a clock and set the hands at "10 after 11," 9% set the hands at "10 to 11." This low base rate of occurrence suggests the error was not highly sensitive to neurological impairment or diagnostically specific.
