Explanation: Victoria is using her critical thinking skills to execute mindfulness.
Mindfulness in Psychology can be defined as aying attention on purpose, in the present moment, and non-judgementally which can develop through the practice of meditation, and other training.
It is an act of focusing one's attention at the present moment and accepting it without judgement.
In this example, john's whistling is serving as a discriminative stimulus.
This procedure, studied by Ivan Pavlov, shows a stimulus ( in this case the action of John's whistling) and a response ( the cattle run to the food trough).
Pavlov studied it with dogs. He realised that when a trainer fed them, dogs salivated. So, he presented the dogs with a "stimulus" ( the sound of a metronome) and when he gave the dogs food. After a few repetitions, when the dog listened to the stimulus, it salivated.
Virginia, North Carolina, and Georgia were the three states with 1 battle during the American Revolutionary War.
