Mrs. Ridcully, a dog trainer, is struggling to train a dog to learn a new trick. Mrs. Ridcully classically conditioned the dog to sit whenever she whistled. However, the dog responds only to Mrs. Ridcully's specific whistle, not to the whistle of the dog's owner (who hired Mrs. Ridcully to train the dog). What operant principle is causing this difficulty?
- Extinction
- Selective attention
- Instinctive drift
- Proactive interference
- Discrimination
