摘要: <正> 从发展的观点来分析,儿童的生长与发展虽然基本上是連續的与逐漸的,但有时加速,有时減速,并不是直綫的与等速的。許多作者(Courtis 1937、1948、Thorpe和Cruze 1956、Watson和Lowrey 1958等)都指出,自嬰孩发展至成人可能存在若干显然加速的时期,因而形成发展的周期或閉环。从心理、生理与解剖等多方面来綜合探討上述周期或閉环,无疑是儿童发展分期的重要客观基础。就嬰孩至7岁这个

Abstract: Electroencephalographic investigations of the spontaneous and "evoked" potentials were performed on 758 normal preschool children with an Ediswan 16-channel electroencephalograph. "Evoked" potentials was initiated by "threshold" single and repetitive flashes of light:1. EEG aged 4—7 years show an outstanding competition between α and θ waves. At about 7 years of age this competition is finished on 51.5% children in the occipital region, but only on 6.7% children in the temporal region.2. From 4—7 years the occipital rhythmic activity increases in frequency but amplitude stands high with age. The range of changes in frequency always exceeds 1±1/sec.3. The vast majority of children aged 4—7 years shows the phenomenon of "dicrotic" and "muhicrotic".4. Short duration and low percentage of display are the traits of the "blocking" responses elicited by "threshold" single flashes on preschool children.5. Occasional display, narrow range of "driving" frequency and absence of afterdischarge are the traits of the "driving" responses elicited by "threshold" repetitive flashes on preschool children.6. Our results show that it seems to have a period of acceleration of brain's development between 5—6 years of age.
