Note: Values in the upper triangle (above diagonal) are Kendall’s τ correlations and reflect the rate of concordant ranked pairs of variables. Given the small sample sizes (i.e., n = 10), the non-parametric Kendall’s τ is recommended as it reflects whether, when ranked, two variables tend to place items in the same order. Since Kendall’s τ is less familiar, the lower triangle (below diagonal) are Spearman’s ρ. The mean, standard deviation, and range of each variable (by column) is shown in the bottom two rows.

STX = SUBTLEX_US, Freq. = word frequency, diversity = semantic diversity, AoA = age of acquisition, BOI = body-object integration, SD = standard deviation
