4 What is experience?08-026The stimuli that you encounter both pre- and post-natally as well as in later stages differentiate neuron function.Examples: sound, touch, vision, smell, food, thoughts, drugs, injury, disease, physical activity, etc.Experience begins in utero that effects the differentiation and function of the neurons in the brain.Experience that affects brain development in the early years of life include the neural pathways that relate to sound, touch, vision, smell, thoughts, drugs, injury, and disease. Obviously, food (nutrition) is crucial for the development of neurons. Adequate nutrition without the other experiences will not lead to full development of the architecture of the brain.Kolb, U Lethbridge
5 Health(physical and mental) Learning (literacy) Behaviour 03-080Experience-Based Brain Development in the early years of life sets neurological and biological pathways throughout life that affect:Health(physical and mental)The exponential growth in knowledge from the neurosciences about the development of the brain and related biological pathways has provided clear evidence as to how experience in early life affects the development of the brain and biological pathways. Experience-based brain development in the early years of life sets neurological and biological pathways that affect, throughout life, health [physical and mental], learning (literacy) and behaviour. Thus, experience in the early years of life can set trajectories that affect health, well-being and competence for life.Learning (literacy)Behaviour
7 Early Child Development and Language 04-200Early Child Development and LanguageStarts early – first 7 months – neurons differentiate language sounds (e.g. English, Japanese)Sets capability for masteringmultiple languages in early lifeSets literacy, language and learning trajectory for the second and third stages of development
8 Literacy Levels for the Population Ages 16 to 65 – USA 05-178Literacy Levels for the Population Ages 16 to 65 – USAProseDocumentQuantitativePercentThe United States Department of Education has replicated the OECD studies. This slide is adapted from Adult Literacy in America: A First Look at the Findings of the National Adult Literacy Survey. U.S. Department of Education The results are similar to the OECD studies of literacy in the United States and other developed countries. In developed countries, nearly 50% of the U.S. population is at Levels 1 and 2 (low) and about 5% are at Level 5 (high).LowHighLevelNALS, p. 17, 2002

U.S. Department of Education. 2002) shows the competence of the adult population in literacy and the burden of physical and mental health problems. In terms of the literacy assessments, Level 1 is low and Level 5 is high. There is a gradient in health status when the data are plotted against the level of literacy competence of the population.The OECD data on developed countries shows a significant correlation between levels of literacy and life expectancy. It may be because the brain pathways that affect language and literacy have some link to the LHPA (stress) pathways that affect behaviour and health.LevelNALS, p. 44, 2002

21 The Commission recommends that: Recommendation 5.2The Commission recommends that:Governments build universal coverage of a comprehensive package of quality early child development programmes and services for children, mothers, and other caregivers, regardless of ability to pay.WHO, August 2008
22 10-002Of all the countries in the Americas, Cuba’s programs of nutrition and stimulation for rural and urban children provide the best example of equity for early human development in the Americas. We all can learn from what Cuba has accomplished.
