Reflex arena diffuse colour2/13/2023 ![]() However, there was considerable variation among workers within each colony in their performance in both learning tasks. Our results showed neither a correlation, nor a trade-off, in individual performance for learning tasks using different sensory modalities. Olfactory learning was assessed using proboscis extension reflex (PER) conditioning and visual (colour) learning was examined using a well-established free-flying paradigm. Do individuals that are good at learning in one sensory modality also perform well in another (performance is correlated between modalities), or do individuals demonstrate specialisation in learning performance in one modality (trading-off performance between modalities)? We tested these hypotheses by examining the performance of 76 Bombus terrestris workers, from four colonies, in both an odour-and visual learning task. ![]() ![]() Whilst there is appreciable variation in the cognitive performance of animals, we know surprisingly little about the extent to which learning varies among individuals across different sensory modalities. ![]() Animals use cues from a range of sensory modalities to discriminate stimuli and as predictors of reward. ![]()
