Results of normality and homogeneity tests for the distributions of the ratings of the spatial words.

Note. The Anderson-Darling normality test and the robust Brown-Forsythe modification of Levene's test (see Conover, Johnson, & Johnson, 1981) to compare two variances were used. The popular F-test (or so-called variance ratio test) is known to be non-robust to small and/or unequal sample sizes and non-normal distributions (Sun, Chernick, & LaBudde, 2011), and hence was not used.
