How do diverse populations with different cultures and language communicate with each other?

Science of Early Child Development “The science of ECD shows that brain development is highly sensitive to external influences in early childhood starting in utero with life long effects.” WHO, 2008
Experience-Based Brain development in the early years of life sets neurological and biological pathways that affect throughout life: 03-080 Health Learning (literacy) Behaviour
08-039 Why do we care about brains? You are your brain. BUT Your brain is not just produced by your genes. Your brain is sculpted by a lifetime of experiences. The most important time in brain development is the first few years of life. Kolb, U Lethbridge
08-026 What is experience? Everything that you encounter both pre- and postnatally as well as in adulthood… Examples: sounds, touch, vision, smell, food, thoughts, drugs, injury, disease… Kolb, U Lethbridge
08-029 Does Experience have the Same Effects on Brain Development at Different Times in Life? No ! There are qualitative differences at different stages of life. There is something fundamentally different prenatally vs infancy vs juvenile vs adult. One difference is gene expression. Kolb, U Lethbridge
08-081 All the neurons have the same DNA. How do they differentiate for their diverse functions?

01-012 Early Learning and Criminal Behaviour "Significant correlation with registered criminality (teenage) appeared for language development at 6, 18, and 24 months.” Early verbal skill development depends upon language exposure which requires holding the infant and toddler (touch). Stattin, H. et al Journal of Abnormal Psychology 102; 369, 1993
08-031 A “Natural” Experiment: Romanian Orphan Adoption • Children adopted into middle class homes after 8 months in the orphanages show at 11 years in contrast to children adopted early: • Abnormal brain development (small brain, low metabolic activity, abnormal EEG) • Social and cognitive problems (IQ loss) • 3. High vulnerability to behavioural problems (ADHD, aggression) Kolb, U Lethbridge
08-014 Epigenetics (nature and nurture) The process by which normal gene expression is altered by experience. Genotype vs Phenotype
07-123 Brain Pathways “Higher levels of brain circuits depend on precise, reliable information from lower levels in order to accomplish their function. Sensitive periods for development of lower level circuits ends early in life. High level circuits remain plastic for a longer period.” Knudsen 2004

07-105 The Brain and French Immersion
Levels of Literacy: A Reflection of ECD 01-040 Level 1: indicates persons with very poor skills. Level 2: people can deal with material that is simple. 42% of Canadians Level 3: is considered a suitable minimum for coping with the demands of everyday life. Level 4: people who demonstrate command of higher-order processing skills. Level 5: competence in sophisticated reading tasks, managing information and critical thinking skills.

IT takes a Village to Raise a Child What does it take to raise a village?
Changing the Way we do things Whether the issue is early human development, childcare, french immersion, food security, youth engagement, literacy, suicide, global warming, poverty, employment, crime, civil societies….
All our governance systems must move towards an intersectoral/holistic approach. This is especially important at the local level where services, programs and relational supports need to be connected and integrated towards a communities vision
The Components to Raise the Village The Message: Critical importance of early human development - hope The Process: who to involve, where to start, questions to ask, steps to follow. The Content: What are the components that create a comprehensive and integrated system of programs and supports The Evidence: EDI, 18 month screening…
School communities are a natural place to start to engage the broader community with an inclusive and meaningful process.
Get the Message Out !Regional Leaders Retreats • The revitalization of community comes through citizen participation and through having communities that understand EHD and value all their families and children. • An important first step in mobilizing community is to foster and encourage the coming together of a new cross sectoral leadership - with the usual and unusual suspects - to share their knowledge, assess needs, determine priorities and then commit to act!
CARS-Communities Achieving Responsive Services- “Road Map” *Begins with what currently exists in the community and collectively plans the future-involves stakeholders. *Develops a common community vision, community values, and community action plan *Mobilizes community partners and resources. *Is ongoing, celebrates and revitalizes the “village” *Developing regional models of integration will help to provide evidence and to inform policy framework towards universality.
