You Have Been Called as a Sport Psychology Consultant to Meet

You have been called as a sport psychology consultant to meet with a team of baseball players. The coach tells you that a few of the athletes on the team are extremely emotional and get angry and upset when they don't do well, or when the team doesn't do well. The coach has noticed that when these athletes start to get angry, the mood of the team takes a turn for the worse very quickly, and it is affecting the team's performance and the athletes' relationships with their teammates. The coach tells you that so far he's tried to let the athletes have their space and try to figure it out for themselves, but his approach is not working and the problems seem to be getting worse. What are two key concepts you would tell the coach and the team to educate them about social environmental factors influencing emotions within the team?
