文摘

Individual ants show consistency in their exploratory behaviour. Ants learn to associate a positive or negative stimulus with spatially distinct positions. Cognitive judgement bias was tested with the stimulus in an intermediate position. Fast explorers showed a pessimistic bias while slow explorers an optimistic bias. Results suggest a link between personality and cognitive state in eusocial insects.
