SPCL 7804 Human Development: Session 5: Unit 2 – The Early Years, continued

Open Educational Resource (OER) created for Professor Elizalde-Utnick's SPCL 7804 course.

Video: Example of Egocentrism Using Piaget’s Three-Mountain Task

Video: Example of Centration – Lack of Conservation

Video: Piaget vs. Vygotsky on External Speech

Piaget called external speech “egocentric speech,” representing its non-communicative nature and lack of perspective-taking. In contrast, Vygotsky considered external speech to serve a self-regulatory role. Can you identify this latter function in the video?


In this session we will explore the preschool child’s acquisition of skills in several developmental domains: motor skills; self-help skills; and cognitive development. We will focus much of the session’s time discussing cognitive development, particularly, Piaget’s preoperational period, Vygotsky’s theory of cognitive development, and information-processing theory.  We will begin with a quiz on the assigned reading and then discuss the material and engage in application activities.


Text Ch. 4, pp. 110-133 (Library linkPDF link)
