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.
In a dictatorship there is one party and one leader, in some dictatorships you are not free to speak your mind, most dictators (leaders of a dictatorship) adore their countries, most dictators emphasise war within their country, in a dictatorship the country is entirely controlled by the leader, no one else. Always be sure to review.
Hope this helps :)
