In the articles Fisher et al. (2016) and Blair & Raver (2012), they both describe how early adversity have long-term consequences on child development. In the Blair & Raver article quality of caregiving is then in turn hypothesized in the article to act as a key mediator of the linkage between children’s exposure to poverty-related hazard and subsequent physiological, neurobiological, and cognitive development (Blair & Raver (2012), pg). For example in a study with rats, the variation in the maternal behaviors in the rat that initiate the cascade from the behavioral to the genetic level and back again is in part driven by the quality of the environment in which development is occurring. The authors understand this as the idea here is that environmental quality leads to particular types of caregiving behaviors that initiate a physiological cascade leading to patterns of development that are appropriate or beneficial for that environment (Cameron et al., 2005; Meaney, 2001, 2010, As cited in Blair & Raver (2012), pg. ). In the context of adversity on early development, studies show children with a heightened vigilance that may be evolutionarily beneficial in the short run by keeping children alert and ready to respond when facing potentially threatening situations or interactions at home or at school. However, that same level of behavioral vigilance may translate to a level of wariness or reticence with unfamiliar teachers and peers that carries longer term social costs. These…
