很多人都认为小孩头大就一定聪明,这是他们将一个人的智力高低和头颅的大小作牵强附会的联想。实际上,单纯以头颅的大小来判断一个人的智力是不科学的。头颅的大小,是以测量头围来判断的。测量时,用一根皮尺沿着头后枕骨处向前经眉毛上面绕一周,在皮尺上所见到的数字就足头围。婴儿头围平均为33厘米;6个月时为42厘米;1～2岁为47厘米;成人头围平均为52厘米。6岁儿童的头围已接近成人了。如果孩子的头围明显

In fact, it is unscientific to judge a person’s intelligence simply by the size of the skull. The size of the skull is determined by the circumference of the measuring head. Measurement, with a tape measure along the head and occipital bone around the previous eyebrows around a week, the number seen on the tape measure enough head circumference. The average head circumference of a baby is 33 cm; 42 cm at 6 months; 47 cm at 1 to 2 years of age; and the average head circumference of an adult is 52 cm. 6-year-old child’s head circumference is approaching adult. If the child’s head circumference is obvious
