我的儿子已5岁,语言发展较好,思维活跃,可有时他会故意说反话。例如比赛时,会自定规则:谁输谁就算赢,谁赢谁就算输。有时给他讲故事后要他回答问题,他明知道答案,可会故意说错,还说是要考考妈妈。请问碰到这种情况,该怎样引导他,从而促进他思维的健康发展? My son has been 5 years old, the language development is good, active thinking, but sometimes he will deliberately talkative. For example, when the game, will set the rules: who lose who win, who win who even lose. Sometimes he was asked to answer a question after telling him a story. When he knew the answer, he could deliberately wrongly say that he was going to test his mother. Can I encounter such a situation, how to guide him, so as to promote the healthy development of his thinking?
