LITERACY Why and how does reading change children?
While the content of what children read is important, it is literally the ACT of reading that physically changes the brain of a child

Sequential Neurodevelopment • The brain is undeveloped at birth • The brain organizes from the “bottom” up - brainstem to cortex and from the inside out • Organization and functional capacity of neural systems is sequential • Experiences do not have equal “valence” throughout development
The more a neural system is “activated,” the more that system changes to reflect that pattern of activation • This is the basis for development, memory and learning
Patterns and Organization of Brain Function • Patterned activity is required to effectively develop and organize neural systems • With chaotic sensory input, inconsistent patterns of activity or sensory input, there may be abnormal development and related dysfunctions
The brain develops and organizes as a reflection of developmental experience, organizing in response to the pattern, intensity and nature of sensory and perceptual experience
Cortical Modulation As the brain develops in this sequential and hierarchical fashion, and the more complex limbic, sub-cortical and cortical areas organize, they begin to modulate, moderate and ‘control’ the more primitive and ‘reactive’ lower portions of the brain
What Builds Cortical Modulation Capacity? • Healthy attachment experiences leads to healthy development of limbic and cortical areas involved in social affiliation and modulation of impulsivity • Education, specifically literacy, helps build in cortical systems that modulate reactivity • Therefore, enriched cognitive and socioemotional experiences during childhood help build healthy brain
Literacy and Brain Organization • Repetitive, patterned cognitive stimulation helps organize various cortical association capabilities • These ‘reading-related’ brain systems facilitate abstract cognition, creativity and modulation of impulsive, less-mature functioning • Learning to read literally changes the brain – increasing the probability of “humane” problem solving and conflict resolution
