The document discusses the Experience-Dependent theory of early brain development. The Experience-Dependent theory states that specific experiences shape brain development, unlike Experience-Expectant development which is universal across humanity. An example is provided of a boy named Jay whose eye was covered as an infant, preventing the brain from developing the neural pathways for sight in that eye. The document also discusses cognitive distortions like all-or-nothing thinking and overgeneralization. Finally, it covers Dynamic System Theory, which explains that a child's current experiences, memories, and motor skills work together to help them solve problems and develop concepts over time through changing experiences.
