Section 2 Introduction - Developmental psychologist, Jean Piaget believed the preschool years to be a time of preoperational intelligence. Meaning that children at this stage can use symbolic thought, however, they still lack the ability to use logic (). With the development of symbolic thought preschoolers are primed for language acquisition and are often called language sponges. Also seeking to explain the cognitive development at this stage of life, Lev Vygotsky, focused on the social aspect of early childhood learning process emphasizing the aid of mentors. These two foundational theories will be discussed in this section as well as their implications for early childhood education.
