190 The Professional Counselor | Volume 11, Issue 2 and chronic stress posed by racially hostile or unwelcoming environments, ACEs screening tool development has continued to evolve (e.g., the ACE-IQ; Cronholm et al., 2015). Additionally, the need for improved understanding of protective factors that may interact with or even counteract ACEs has been identified. For example, researchers developed measures like the Health-Resiliency-Stress Questionnaire (Wiet & Trauma-Resiliency Collaborative, 2019) and Benevolent Childhood Experiences (Narayan et al., 2018) and Positive Childhood Experiences (Bethell et al., 2019) scales to identify positive childhood experiences that may also influence health and resilience amidst adversity. Such measures include factors associated with the individual student, such as self-acceptance, as well as systemic factors, including the community (e.g., culture, community traditions, fair treatment, opportunities for fun, resources for skill development and assistance), school (e.g., caring adults, sense of belonging), peers and supportive others (e.g., role models and non-parent adults), and family (e.g., home routine, safety, family cohesion, emotional expression), all of which may contribute to risk and resilience. It must also be noted that the interaction of risk and protective factors experienced by an individual is also an important consideration in research and practice. For example, Layne et al. (2014) proposed the Double Checks Heuristic, which involves considering protective factors, vulnerability factors, and negative outcomes when conceptualizing clients. The Double Checks Heuristic helps clinicians and researchers consider risk factors as well as strengths and protective factors to find the best ways in which to intervene and support clients (Landolt et al., 2017). Biological Development As is clear in the ACEs literature, childhood experiences have strong and significant relationships with biological development and physical health outcomes later in life (Copeland et al., 2018; Edwards, 2018). Specifically, childhood experiences are integral to brain development and gene expression (Anda et al., 2006). During this period, the brain is highly sensitive to the experiences a child has, adapts to these new experiences, and learns from them by adapting through growth and development. Chronic stressors, adverse experiences, and traumas disrupt equilibrium in the developing brain, especially during sensitive periods of development (Glaser, 2000). Consistent disruptions to the developing brain’s homeostasis create new, less flexible patterns of operation within the brain (Perry & Pollard, 1998). Researchers have linked ACEs to impairment in brain development and neurological functions. Both structural and functional impairments occur in the brain as a result of traumatic experiences in childhood (Edwards, 2018). Specifically, sexual abuse, neglect, and other ACEs are believed to impede brain development because of insecure attachment and continued stress response in the body. Attachment in infants is linked to heartrate variability and the exposure to neurotransmitters like oxytocin and dopamine in the brain (Glaser, 2000). Chronic stress is also linked to the death of hippocampal cells that contribute to memory, learning, and emotion. Further, Roth et al. (2018) examined the impact of severe neglect on brain development in the amygdala—the location in the brain responsible for emotion regulation. The authors found a relationship between right hemisphere amygdala volume, anxiety, and neglect in adolescents aged 9–15. Boys who experienced severe neglect showed increased amygdala volume, which contributed to higher instances of anxiety and fear response within the brain (Roth et al., 2018). Psychological Development Childhood emotional and psychological development is paramount to success in children. Children who are not at economic risk and who exhibit higher levels of self-regulation are more likely to experience success in school (Denham et al., 2012). Parenting style also appears to be a major contributing factor to positive psychological development (Le et al., 2008).
