English: Error Example 1. Following five trials of successful cap pushing, a discrimination task was performed. The previously trained cap was moved to the side and a novel cap was used to cover the sucrose feeding well. The trained cap was counterbalanced between cross patterned and solid caps, and the novel cap presented for the discrimination task was different in shape. Upon first return, 11 of 12 bees pushed the cap previously trained, ignoring the cap that actually covered the sucrose well. If the bee pushed the cap off the plate, it was quickly returned. Bees would continue to push the incorrect cap when available (see S5 Video: Error Example 2).
