In addition to our analyses based on bees for which the learning speed could be quantified using exponential decay curve fitting with Microcal Origin (OriginLab Corporation), we also found no significant difference between the sexes in the prevalence of learning curves, to which no decay function could be successfully fitted, which was the case for 42 of 178 (males) and 47 of 167 (workers) learning curves (? 2 1 = 0.93, P = 0.33).

We found a significant difference in overall learning speed between the two training sequences (GLM: Wald test = 5.71, df = 1, P = 0.02) associated with asymmetrical learning performances on feeder types with similar colours. For both small-distance colour pairs (yellow-green, CD: 0.061; blue-purple, CD: 0.189) initial choice accuracies were significantly different depending on which of the two colours in the pair was rewarded. The choice accuracies on green rewarding and yellow nonrewarding feeders was significantly lower for the first 30 visits than those achieved on the reverse challenge (10 visits: t92 = 3.48, P 91 = 2.45, P = 0.02; 30 visits: t91 = 4.67, P 105 = 2.08, P = 0.04; 20 visits: t105 = 2.45, P = 0.02). In both cases these differences diminished as training progressed (green-yellow: 40 visits: t90 = 1.83, P = 0.07; 50 visits: t88 = 1.47, P = 0.14; blue-purple: 30 visits: t104 = 1.55, P = 0.12; 40 visits: t104 = 0.81, P = 0.42; 50 visits: t102 = 0.34, P = 0.74). No significant asymmetries in choice accuracy were found for the two colour pairs consisting of highly different colours (purple-green, blue-yellow). This effect, however, was not affected by sex and was similarly seen in males and workers (GLM: seq?sex: Wald test = 0.66, df = 1, P = 0.42). The differences also did not extend to the latency to switch (GLM: sex: Wald test = 0.67, df = 1, P = 0.41; seq?sex: Wald test = 0.32, df = 1, P = 0.57).
