In your own words, using citations to support your assertions, compare and contrast Piaget’s and Vygotsky’s theories about cognitive development. Which theory do you believe is most sound, based on your own experiences? Share one personal experience that supports your stance. Share only information that you are comfortable with, or you may use another’s experiences or a fictitious example. Note that your posting should be thorough and 300 to 400 words. If you quote the course textbook, identify the section where you took it from and add to the citation where you would normally add the page number (e.g., Shriner & Shriner, 2014, Chapter 1, section 1.1).
