Symmetry perception in an insect

Article Abstract:

Bees and flower-visiting insects can be trained to discriminate bilaterally symmetrical and asymmetrical patterns and generalize this training to novel stimuli. Their preference for symmetry or asymmetry is based on experience, and they learn this symmetry detection as a perceptual category. Bees are predisposed to learning and generalizing symmetry. If trained for symmetry, they show preference for novel symmetrical objects more frequently and for longer duration than those trained for asymmetry do for the novel asymmetrical objects.

Cognition by a mini brain

Article Abstract:

Liu and colleagues have reported results on visual learning by Drosophila and show that individual flies can undertake complex tasks. They showed that files can generalize a trained response to several other, different environmental contexts. The study provides insights into the function of central brain structure on an elementary form of cognition and the role of context in learning.

The concepts of 'sameness' and 'difference' in an insect

Article Abstract:

Research is presented concerning the flexibility which is displayed by honeybees in the processing and learning of information. The development of 'difference' and 'sameness' concepts by honeybees is discussed.
