marginally significantp<0.07
For length 3, a two-way ANOVA for the three representations and the second and third positions showed a significant interaction (F(2, 20) = 7.07, p<0.01), a marginally significant effect of positions (F(1, 10) = 4.73, p<0.07), and a significant effect of representations (F(2, 20) = 36.95, p<0.001).
