3A Bit About Our Purpose: To create a safe learning environment that nourishes and promotes your thinking about “you” in the context of your relationships with children, families, and staff.As facilitators, we are committed to supporting creative and open exploration of relationship-based work as it applies to your setting.We hope to create a “holding” environment that furthers your journey in this important work.Take advantage of the “Wondering Wall”.
4It’s all about the bricks and mortar: Infant Mental Health as the “Context” for Robust Early Intervention Services.

6What do we know about the relationship between early relationships and brain development? Infants develop in the context of relationshipsTheir brains develop neural connections in response to their experienceThe quality of the relationship between parent and child matters most, as they need experience with an effective “relational partner” in order for the parts to organize into a “self”
7Key Ingredients: Emotions… Emotions organize behavior……. and lay the foundation for sense of self (inner working model).
8Key Ingredients: Social Infants are biologically predisposed to interact with others.Originates with survival need.Harlow’s work with rhesus monkeys demonstrates the critical role of contact with others in development.
9“There is no such thing as an infant… “There is no such thing as an infant….If you set out to describe a baby you will find you are describing a baby and someone. A baby cannot exist alone, but is essentially part of a relationship.”D.W. Winnicott, 1966
10Ingredients: Relational Relationships provide the framework and context in which behaviors are organized.The Still Face Procedure by Ed Tronick provides an example of the opportunities that exist in each interaction.
11The Importance of Relationships Relationship is the fuel that drives development, affecting basic capacities such as self-regulation, exploration and learning, identity, and interpersonal understandingThe parent (relational partner) is the organizer of the child’s psychological experienceRelationship can be stressed by internal and external factors
12Relationships Effect virtually all aspects of development: IntellectualSocialEmotionalPhysicalBehavioralMoral

14Taken together, these ingredients comprise the key components of infant mental health.How do we as professionals who work with young children and their familiesActivate and nourish the growth of these ingredients to create robust programs?What are some key ingredients of Early Intervention programs?
16An integrated understanding of attachment and how it affects development An understanding of the attachment system and the relationship between security and explorationCan a child form different attachments to different people?How does attachment affect self-regulation, exploration, peer relationships?
17An understanding of the importance of organized stimulation in the early years An awareness of the role of relationship in brain development as well as the role of the environmentAn awareness of the effects of environmental stress on brain development
18An understanding of the complex and long-lasting factors that affect the relationship between parent and childAn understanding of the effects of the parent-child relationship on developmentAn appreciation for the deeply PERSONAL history and convictions that every parent brings to parentingA sensitivity to the nuances of cultural and familial differences in parenting
19Relationally-based intervention with parent and child Skills of observation, regulation, reflection, translationProfessional use of self: noticing, feeling, containing, assessing – learning to promote strengths by “being with”Helping parent learn new skills for self and child: think about, feel for, act on behalf of, derive pleasure from
20A bit of basic information about brain development
21Hardwired to ConnectMechanisms by which we become and stay attached to others are biologically primed and increasingly discernable in the basic structure of the brain.Nurturing environments, or the lack of them, affect the development of brain circuitry.Nurturing touch promotes growth and alertness in babies.Presence of a secure attachment protects toddlers from biochemical effects of stress.Field, 1986; 1995Gunnar, 1989; 1996

24Gene / Environment Interaction Environments can influence genes as they release. Their intensity can either reduce or increase genetically based risks.The interactive dance between genes and environment is much more ongoing than once thought. Of course we know that genes set the stage for how we experience things but now we also know that environment influences the workings of genes and how they are expressed. Environment can influence intensity of release in ways not previously understood.2. We don’t want to give the impression however that gene is not extremely powerful. The brain is formed basically by genetic code.Sometimes there are problems.Neurulation problemsanencephaly (absence of 2 hemispheres of brain)spina bifidaCell Proliferation problems (bad cells created)Fetal alcohol syndromeCell Migration problemsschizencephaly - cortex is entirely missingagenesis of the corpus callosum (absence of it causes communication problems)

28Brain Architecture is Built Over Time Brain development progresses in a hierarchical, “bottom-up” sequence, with advanced skills built on more basic capabilities.As it develops, the quality of brain architecture establishes a sturdy or weak foundation for learning and behavior.Brain circuits consolidate with increasing age, making them more difficult to rewire.The timetable of brain plasticity varies: it is narrow for basic sensory abilities, wider for language, and broadest for cognitive and social-emotional skills.1.

32Experience creates Expectation which alters Perception 1. The early experiences a child has, when they happen repeatedly, create the condition of expectation – because they happen so often we come to expect they will happen again and we come to look for them or sings of them. We then link the chronology and cause-and-effect of happenings with our total understanding of the event. So we come to see the beginnings of behaviors or precursors of behaviors as signs of the behaviors and use them to predict the experience. After a number of these predictions these links come to be used as evidence of the beginnings of behaviors or as part of the actual behaviors themselves. We in a sense come to see thisngs and react to things that sometimes are not really happening.2.

33“Culture influences every aspect of human development and is reflected in childrearing beliefs and practices designed to promote healthy adaptation.”Core Concept #2 “From Neurons to Neighborhoods”National Academy of Sciences, 2000Culture is crucial in infancy to the formation of the first sense of self and the development of intellectual and social styles and patterns. The brain adapts to cultural expectation.
35Prenatal DevelopmentThe nervous system begins to develop just before the third week of gestation.Cell creation and movement to the right spots occur during the first five prenatal months.Brain Size: 25% at Birth; 90% Age 5Talking Reasonably and Responsibly about Early Brain Development, University of MinnesotaThis image shows the growth of the brain in the prenatal period. The brain matures from the neck up with the brain stem at the base of the brain maturing first and the frontal lobes behind the forehead maturing last (around age 30 or later). The pattern is virtually universal among humans.However, brain development should be viewed as the interaction of biology and experience throughout the lifespan and not just what takes place in the earliest years.Talking Reasonably and Responsibly about Early Brain Development, University of Minnesota:(Eliot, 1999)
36Positive StressRefers to moderate, short-lived stress responses, such as brief increases in heart rate or mild changes in stress hormone levels. Learning to adjust to it is an essential feature of healthy development. Examples: meeting new people, getting an immunization, entering child care.Events that provoke positive stress tend to be those that a child can learn to control and manage well with the support of caring adults and which occur against the backdrop of generally safe, warm, and positive relationships.Positive stress refers to moderate short-lived stress responses such as brief increases in heart rate or mild changes in the body stress hormone levels. This kind of stress is a normal part of life, and learning to adjust to it is an essential feature of healthy development. Adverse events that provoke positive stress responses tend to be those that a child can learn to control and manage well with the support of caring adults, and which occur against the backdrop of generally safe, warm, and positive relationships. The challenge of meeting new people, dealing with frustration entering a new childcare setting, getting an immunization, and overcoming the fear of animals all can be seen as positive stressors if a child has the support needed to develop a sense of mastery.National Scientific Council on the Developing Child, Excessive Stress Disrupts the Architecture of the Developing Brain. (2005). Working Paper No. 3., Summer 2005.
37Tolerable StressRefers to stress responses that could disrupt brain architecture, but generally occur within a time-limited period and are buffered by supportive relationships that facilitate adaptive coping. These conditions usually give the brain an opportunity to recover from potentially damaging effects.Examples of stressors include death, a serious illness of a loved one, a frightening injury, divorce.Tolerable stress refers to stress responses that could affect brain architecture but generally occur for briefer periods that allow time for the brain to recover and therby reverse potentially harmful effects. In addition to their relative brevity one of the critical ingredients that make stressful events tolerable rather than toxic is the presence of supportive adults who create safe environments that help children learn to cope with and recover from major adverse experiences such as death or serious illness of a loved one, a frightening accident, or parental separation or divorce.National Scientific Council on the Developing Child, Excessive Stress Disrupts the Architecture of the Developing Brain. (2005). Working Paper No. 3., Summer 2005.
38Toxic StressRefers to strong and prolonged activation of the body’s stress management systems in the absence of the buffering protection of adult support, disrupts brain architecture and leads to stress management systems that respond at relatively lower thresholds, and increases the risk of stress-related physical and mental illness.Examples of stressors include extreme poverty, physical or emotional abuse, chronic and serious neglect, enduring maternal depression, family violence.Early, frequent, and intense stress tunes the brain to set stress regulation mechanisms at high levels. This often results in a child operating in a persisting fear state.Toxic stress refers to strong frequent or prolonged activation of the body stress management system. Stressful events that are chronic uncontrollable and/or experienced without the child having access to support from caring adults tend to provoke these types of toxic stress responses. Studies indicate that such stress responses can have adverse impact on brain architecture. In the extreme, such as in cases of severe chronic abuse, toxic stress may result in the development of a smaller brain. Less extreme exposure to toxic stress can change the stress system so that responds at lower thresholds to events that might not be stressful to others, thereby increasing the risk of stress related physical and mental and illness.National Scientific Council on the Developing Child, Excessive Stress Disrupts the Architecture of the Developing Brain.

40Persistent Stress Changes Brain Architecture Typical -neuron with many connectionsNormalBrain architecture is created by the formation of connections between neurons as a result of interactions with one’s environment, and then the pruning of connections that aren’t used. Neural connections in different areas of the brain are responsible for different kinds of activities. For example, the prefrontal cortex and hippocampus house activities related to memory and decision-making (executive function). As you can see from these depictions of neurons, brains subjected to chronic stress have underdeveloped connections in the areas of the brain most critical for success in school, work, and behavior.In contrast, the Amygdala is the area of the brain that governs our “fear response”. As you can see, in brains subjected to chronic stress, neurons have OVERdeveloped connections in this area -- which can result in exaggerated assessment of and response to fearful situations.ChronicstressNeuron damaged by toxic stress – fewer connectionsPrefrontal Cortex andHippocampusSource: C.

41Under Any Type of Perceived Threat (physical, intellectual or emotional)The Brain:loses ability to take in subtle cluesreverts to “tried & true” behaviorsbecomes more automatic & over-reactiveis less able to use “higher order” thinking skillsloses some memory capacity

43Chemicals in the BrainThe capacity to deal with stress is controlled by a set of highly interrelated brain circuits and hormonal systems that are specifically designed to deal adaptively with environmental challenges. When an individual feels threatened, stress hormones are produced that convert the physical or emotional stress into chemical signals that are sent throughout the body as well as to the brain.“Excessive stress disrupts the architecture of the developing brain”Working Paper #3 Summer 2005, National Scientific Council on the Developing Child.
44Cortisol Kills brain cells Reduces number of cell connections Shrinks hippocampusImpairs selective attentionImpairs thinkingCreates anxious behavior
45Noradrenalin: An Alarm Hormone High levels trigger over-arousal and tendency toward impulsive, hot-blooded acts of violence.
46Serotonin: An Impulse Modulator Low levels = an adaptation to a threatening environment - impulsive, aggressive behaviorNormal levels = clear thinking, social success
47Small Group Questions: How can child care programs help children cope with tolerable stress?How can child care programs avoid exposing infants to toxic stress while in care?How can your program support infants who are experiencing toxic stress outside the child care program?
48Responsive Care Watch child’s cues for signs of interest Ask what the child wantsAdapt your behavior to child’s signalsBathe child in languageConcern yourself with identity messages
49Small Group Question: What has worked for you? What do you think would be most important for infant care teachers and families with infants and toddlers to know about early brain development?What has worked for you?Please share with your group a successful strategy you have used to teach about brain development of infants and toddlers.Please write one statement about each.
50Points to RememberThere are learning windows but for humans most windows never close completelySynapse loss is a natural occurrence based on the pruning of seldom used connectionsEarly emotional and social experiences are as important to the wiring of the brain as intellectual experiencesHealthy early development depends on nurturing and dependable relationshipsExperiences create expectations which alter perceptionsThe early years matter because the interaction between early experience and gene expression shapes the maturing architecture of the brainThe early years matter because the interaction between early experience and gene expression shapes the maturing architecture of the brain . The development of the brain incorporates experience, whether positive or negative, that shapes the brain’s capacities
