It could also be a parent at home criticizing you about a grade to do better in school. When a coach would tell me something that would sting, it would motivate me to do better. I noticed that when the coach said the same thing to a teammate, he would get upset and cry. I never understood why they didn't just improve, instead of pouting at a simple criticism. This is due to differential sensitivity. Differential sensitivity is “the idea that some people are more vulnerable to particular experiences than others” (Berger, 2010, p.21). I was able to accept this criticism from the coach because I was used to having someone at home who criticized my weaknesses so I could improve. When someone criticizes me, I don't take it to heart because I work harder on it to show them that I can do better. The other teammate was more sensitive to the situation and took it to heart. This may be because the teammate was going through a sensitive period. Some small comments to children can still affect them later in life, but some may forget them an hour later. Differential sensitivity is used to “facilitate prediction and therefore target intervention” (Berger, 2010,
