學齡兒童身體成長與側化偏好

The condition of growth and lateral preference in 6-12 years old children

目的：本研究探討學齡兒童身體成長與側化偏好情況，並進一步分析不同性別之側化差異，以提供國小體育教師瞭解目前孩童身體發展和側化偏好情況。方法：以1,337位臺南市國小學齡兒童為研究對象，並填寫身體側化情況問卷，共24細項（含眼睛、耳朵、手、腳與日常用手等慣用側）。結果：身體成長，身高除了6歲兒童男生明顯大於女生，其他年齡則無顯著差異，而男生的體重明顯大於女生。側化偏好方面，身體不同部位的側化情況有明顯差異並傾向於使用右側。不同性別之間的側化偏好沒有差異，手、眼、足與耳朵已傾向使用同側。結論：身體兩側有不對稱使用的情況發生，兒童階段的側化偏好並未因性別因素而趨異，但肢段的使用上已有傾向於使用右邊。Purpose: To investigate the condition of growth and laterality in 6-12 years old children.
