幼儿思维时期可以分为两个部分:思维前期(两岁至四岁)和思维后期(五岁至七岁)。幼儿思维前期最重要的部分包含了语言、符号和象征性游戏。在开始时,符号和象征性游戏的作用尤显重要,因为它们能表明孩子即刻浮现某一具体事物特性的能力。例如,孩子会把玩具熊称作“娃娃”,就表明,玩具熊能表示出或象征着“娃娃”这一概念。玩具熊是一个“象征性”的娃娃。语言的进一步发展,使幼儿能够通过使用词语表达对周围情景所产生的感觉。幼儿可以使用词语确定所需之物,然而,由于他们自身的体验和感受有限,他们对周围世界的洞察力和理解力显得很不成熟,还不能轻易地区别精神的、物质的以及社会性的实际事物和具体现实。例如,如 Early childhood thinking period can be divided into two parts: pre-thinking (two years old to four years old) and thinking late (five years old to seven years old).
