Living Without: The Effects of Poverty on Child Development

For many decades we’ve known that poverty can have a negative impact on child development. The existence of federally funded programs like Head Start and Early Head Start is a testament to the fact that even our legislature understands this at some level. Recently, however, research has led to evidence that the direct relationship between income and brain structure is very large and seen very early in development (Blair, 2016). Today we will discuss some specific results of these recent studies, how caregiving can impact these outcomes, and how the Growing Great Kids and Growing Great Families curricula can help you as you support families in their efforts to overcome the effects of poverty in their child’s development.

Research tells us that the effects of poverty on brain development are seen as early as infancy and the children in low income families have brain volumes that are nearly half a standard deviation smaller than those not living in poverty (Hanson, Hair, & Shen, 2013). These differences were found to be the most pronounced in the parts of the brain that are responsible for executive functioning (Lawson, Duda, & Avants, 2013). Before we move on to discuss what can be done about this, let’s first see if we can get some understanding about what causes the situation, from a neurobiological model.

Early research on child development would lead us to believe that it was all about the reduced opportunities for learning that children living in poverty have. As more disciplines come together to study this, however, it becomes clear that in addition to the reduction in positive stimulation, poverty is also characterized by a lot of other stimulation that actually negatively impacts brain development (Blair, 2016).

“The presence of chronic stressors such as noise, including background noise like that associated with ongoing and unmonitored television, household chaos, and conflict among family members” can adversely impact the brain (Coley, Lynch, & Kull, 2015). These kinds of chronic stressors early in life lead to an overabundance of stress related hormones. Excessive stress hormones are toxic to the developing brain and result in a whole host of negative cognitive, emotional, and behavioral consequences (McEwen & Gianaros, 2010). Chronic stress also alters neural activity in the brain, establishing responses that cause the developing child to become more reactive and defensive (Loman & Gunnar, 2010).

Contributing to this perfect storm, we must also consider the idea that often, when parents are faced with stressful conditions within the home, they are at greater risk for lack of warmth and sensitivity in caregiving. This possible lower parental sensitivity can increase the likelihood that children will have elevated cortisol levels. Elevated cortisol can lead to changes in the brain that cause difficulty regulating emotion and behavior (Evans, Gonnella, Marcynyszyn, Gentile, & Salpekar, 2005). When you combine all of these pathways, we begin to understand why we see wide disparity in school readiness and achievement, and positive life outcomes (Blair, 2016).

Let’s think for a minute though about the fact that some families are able to maintain high levels of nurturing care for their children despite the struggles of poverty. When this happens, the responsive caregiving acts as a protective buffer for the child’s developing brain. Growing these kinds of resilient families is a common goal for both Great Kids Inc. and most of the programs using the GGK and GGF curricula. Let’s take a look at some of the resources within the curricula for supporting the kinds of positive parenting behavior that can have a huge impact on the developing brains of children living in poverty.

There would probably be justification for listing almost everything that is included in GGK and GGF, as it is all designed specifically to target exactly the kinds of threats to the developing brain that research has identified. That all-inclusive list, however, would probably be less then helpful. Instead we’ll look at a few specific modules that are focused on helping parents understand the critical nature of their parenting behavior in growing a resilient child. When they begin to understand why they are so important in the development of their child’s brain, the how will become much easier for them.

All of the Daily Do’s, of course, will be important for this process, as well as Getting in Sync and Ready for Play. All of the Social and Emotional, Physical and Brain, and Play and Stimulation modules in each unit of each manual also apply here. These won’t be listed repeatedly, but be sure to include them in planning home visits. In addition, you will want to pay particular attention to the following sections:

The struggles of poverty are vast and very real. They can’t be righted with just one simple solution, it requires a multi-pronged approach in which we each play a role. During an initial interview with a family seeking services, one four year old little girl spent most of the time drawing pictures while her mom talked with the worker. As they were walking out the door, the child turned and asked “Are you really going to help us?” (Benfer & Walsh, 2016)

Out of the mouth of this little girl came the real question that we are all called to ask ourselves everyday…are we really going to help…and even further…how are we going to do that? The brain is where all thought and emotion originates. Assuring that each child’s brain is provided with everything that it needs to develop to its full potential is at the very heart of the work we do. As individuals and as a society, we need to use all the tools we have at our disposal to protect the brain development of our children.

“Can I play the drums again?” they asked. Without giving it a moment of thought, a “no” came out of my mouth. It wasn’t the most convincing ‘no’ ⸺ more of a feeble reaction to the extra effort this activity would require when my patience was already thin. To this child, that no from their warm-hearted aunt sounded negotiable, and the lure of the shiny drum kit won over.
