The ducklings with the pecking mechanical mother, though, followed much more closely. But as they grew, there would be more distance between them. Over time, he went on, the ducklings in the control group would waddle along behind their mother. And then they watched the ducklings grow and imprint bond with their mother. Each group was pecked with a different level of frequency. A painful peck, one a real duck would not give. For the experimental group, the scientist used a mechanical duck they had created - feathers, sound, and all - which would, at timed intervals, peck the ducklings with its mechanical beak. The control group was a real mother duck and her ducklings. So the scientists set out to test how that imprint bond would be affected by abuse. Ducks, like people, develop bonds between mother and young. “Some scientists were conducting an experiment, he said, trying to gauge the impact of abuse on children.
