Table 1.
Parameters and 95% confidence intervals of the logistic regression models fitted to each one of the n = 12 bees used during the study. The model describes changes in the percentage of correct choices as a function of time for two different colour discrimination tasks, and statistically tests the significance of the slope. † Confidence intervals constructed based on a likelihood-based profile. § p-values calculated from differences in deviance values. ** Significant slopes at α = 0.05.
