Wilcoxon's sign-rank test was used for paired comparisons. Wilcoxon's rank-sum test was used for unpaired, independent observations. McNemar's test was used for proportions comparing two conditions (2 × 2 contingency tables). For circular statistics, the Rayleigh test for unimodality was used throughout. For continuous analyses, Pearson's r was calculated. For correlations with multiple data points per animal, multiple linear regression (MLR) was performed in Matlab (regstats function). P-values indicate the significance of the explanatory variable of interest after accounting for within animal dependence. If given, r values refer to the full model. Error is reported as mean ± standard error of the mean (±SEM), unless otherwise noted.
