A high school football coach is doing a simulation with his team using backup players as the opponent. In the simulation he even has his assistant coaches dress as referees. He plays the sounds of an opponent's crowd over the stadium's loudspeakers, and asks the referees to deliberately make questionable calls. Gradually, sounds of the crowd will grow more hostile and the referees' calls will become even worse. He has taught his team techniques for managing challenging situations like this. Now they will have an opportunity to use these techniques during the simulation. The coach is using 1 stress inoculation training 2 autogenic training 3 progressive relaxation 4 the relaxation response
