Methods 732 valid questionaires were chosen on the basis of “a component part first, then groups” at random samplings ,and gradual screening according to diagnostic standards by filling in unified survey forms. Results The incidence of nervous behaviors for primary schools’ pupils was 45.08%, with remarkable difference for different grades. The incidence of those addicted to biting fingernails accounted for 29.64%.Mentally habitual spasmodic jerk incidence came to 16.39%, thumb blowing addictors 8.88%, breath holding attacks 4.78%, habitual leg rubbing activities 1.64%, head hitting incidence was very low, all of which had no sexual relation except mentally habitual spasmodic jerk.
