I wonder how the third group of dogs quickly jumped over the fence and escaped?
In 1967, a psychologist named Martin Seligman was researching clinical depression. In an experiment, Seligman placed dogs in three experimental groups. The dogs in the first group were given mild electric shocks, which they could turn off by pressing a panel. Dogs in the second group were given repeated electric shocks regardless of their actions. The third group of dogs received no electric shocks. All the dogs were later put in boxes where they were given electric shocks but from which they could easily escape by just jumping over a low fence. The dogs in the first group and the dogs in the third group quickly jumped over the fence and escaped. The dogs in the second group, who could not stop the electric shocks earlier, made no effort to escape. They simply lay down in the box while receiving the shocks.

They had not gotten out of the box because of the electric shocks.
please help me understand it!
