[a] For graded LS, the one-way ANOVA for the effect of grade produced a significant F (4,1041) value of 93.26, p < .001; the F (1,1041) value for the linear trend was 168.98, p < .001 and for the quadratic trend, F (1,1041) = 197.27, p < .001. Student-Newman-Keuls revealed that 4 = 6<5<3<2. For graded words, ANOVA indicated a significant F (4,1041) value of 50.84, p < .001; the F (1,1041) for the linear trend was 137.91, p < .001 and for the quadratic trend, F (1,1041) = 56.03, p < .001. Student-Newman-Keuls revealed 5<6 = 4 = 3<2. For common LS, ANOVA indicated a significant F (1,1041) value of 100.86, p < .001; the F (1,1041) for the linear trend was 375.26, p < .001 and for the quadratic trend, F (1,1041) = 33.23, p < .001. Student-Newman-Keuls revealed 6<5<4<3<2. For common words, ANOVA indicated a significant f (4,1041) value of 31.47, p < .001; the F (1,1041) for the linear trend was 125.05, p < .001 and for the quadratic trend, .51, ns. Student-Newman-Keuls revealed 6<5 = 4<3<2.
