Pattern learning by honeybees: Conditioning procedure and recognition strategy
In recognizing a pattern, honeybees, Apis mellifera, may focus either on its ventral frontal part, or on the whole frontal image. We asked whether the conditioning procedure used to train the bees to a pattern determines the recognition strategy employed. Bees were trained with the same patterns pre...
