We performed a large number of statistical tests, which raises the problem of evaluating statistical significance when performing multiple comparisons. None of the effects we report below would be likely to survive the overly stringent Bonferroni correction. However, questions about the number of tests to correct for, whether the GZTS scales are truly independent, and whether the Bonferroni correction is appropriate, do not have clear-cut answers (47). Consistent with most previous studies (e.g., 29, 31), we therefore opt to focus on the effect sizes, comparing the results we obtained with those reported in the literature.
