本研究的目的在利用我國修訂貝萊嬰兒發展量表中的「心理量表」對於我國台灣地區2個月至30個月大的1680名嬰兒（男、女各半）施測，以獲得我國嬰兒智力發展之特徵，制訂常模，並提供我國嬰兒保育及診斷之參考，研究結果之主要發現為：1．嬰兒在心理量表各項目之通過率，呈直線性之發展趨向；2．嬰兒智力的發展隨著年齡而呈直線性的發展趨向；3．女性嬰兒智力平均數，比男性嬰兒的平均智力為高。4．在3、5、21、24個月組中，都市嬰兒的智力高於鄉村嬰兒者；5．照顧的方式對於嬰兒智力的發展未產生影響作用。

The purpose of this study aims at standardizing the Mental Scale of Bayley Scales of Infant developemnt, establishing age norms for Chinese infants and toddles and understanding the major characteristics of cognitive function of infants. These knowledge can be for infant caring and clinicat diagosis.

In the 3, 4, 21 and 24 month age groups, subjects of city residence have higher mental scores than the subjects of country residence. 5.
