Correlations of individual test performances in Experiment 1: Visual learning experiment with free-flying bees. Pairwise Spearman rank correlations between the test performances (Percent of correct choices) of individual bees in A the 1st phase of reversal learning (1st RL) and the 2nd phase of reversal learning (2nd RL; n = 27, rho = 0.53, p = 0.005, R² = 0.34), B the 1st phase of reversal learning and negative patterning (NP; n = 33, rho = 0.42, p = 0.02, R² = 0.2) and C the 2nd phase of reversal learning and negative patterning (n = 27, rho = 0.25, p = 0.201, R² = 0.06). Each dot represents data from one bee. The regression line is indicated in orange and the dotted grey lines show the 95%-confidence intervals of the regression. Solid regression lines indicate a significant correlation and dashed lines indicate a non-significant correlation (color figure online)
