From the age between 2-7 years old, a child is in the "preoperational stage" of development, characterized by symbolic representation or thinking and egocentric thinking. The child also tends to plan, perceive, and solve problems based on appearances (e.g. a half cup of water in a wide glass is to him/her smaller in amount compared to the same amount of water in a tall thin glass). A good example of the child's egocentric thinking is most apparent before the child enters kindergarten. When a child is told to hide, he/she usually only covers his/her face, because in his/her thinking, "if i can't see you, then you can't see me!" In egocentrism, the child thinks that other people think and perceive the world the way he/she does. However, a recent study tried to explain this action of "ineffective hiding" in children as their way of demanding or insisting on reciprocity, and mutual recognition and regard, instead of merely egocentrism (source: https://theconversation.com/young-children-are-terrible-at-hiding-psychologists-have-a-new-theory-why-67979)
Explanation:when men are under stressful situations they are more likely to react with anger.
As compared to women, men are less likely to talk about how they feel because sometimes they feel it will make them look weak hence in most times they will burst with anger if they are stressed up by something or if they feel both stress and fatigue .
