highly significantp <0.001
After excluding the four-flash stimulus, a linear regression analysis showed that the number of flashes reported was a highly significant predictor of the number of flashes actually presented ( R 2 = 0.86, F (1,52) = 367.4, p <0.001), with a nearly unitary slope ( β = 0.93, t (52) = 19.2, p <0.001), indicating that as the number of flashes presented increased by one, the number flashes reported was also likely to increase by one.
