Here Viki excitedly watches Cathy Hayes use a hammer to pound a stake into the ground. She then attempts, without a great deal of success, to imitate the action. At the time this clip was filmed, Viki was familiar with hammers, but had never seen one used this way before.

For imitation to succeed, the imitator must pay attention to the action. Viki clearly gives Cathy her full attention on this trial.
