¹ Expression of anger vary around the world. ²Suppose a child has just completed its detailed drawing. ³When a classmate spills a drink, ruining the drawing. ⁴Most American children would respond with anger. ⁵In contrast, children growing up in east asian countries that practice buddhism (e. g ., Mongolia, Thailand, and nepal) rarely respond with anger because this goes against the Buddhist tenet to extend loving kindness to all people . ⁶Instead, they probably remained quiet and experience shame that they had left the drawing in a vulnerable position. ⁷Thus, culture can influences when and how much children express emotion. ⁸Of course, expressing emotion is only part of the developmental story. ⁹Children must also learn to recognize other's emotions.
