Article Synopsis
- Childhood adversity (CA) is linked to higher risks of negative health outcomes, with differences in how various types of adversity affect brain structure during development.
- Recent research indicates that deprivation leads to slower decreases in cortical surface area in certain brain regions, while threat exposure results in increased surface area in areas related to socio-emotional processing as adolescents age.
- These findings suggest a need to reconsider how different forms of adversity affect brain development over time, highlighting the varying impacts on cognitive and emotional functions.
It is well-established that disrupted autonomic nervous system (ANS) reactivity exacerbates risk for long-term maladjustment following childhood adversity (CA). However, few studies have integrated measures of both the sympathetic (SNS) and parasympathetic (PNS) branches of the ANS, resulting in a unidimensional understanding of ANS functioning as a mechanism of risk. Further, past work has primarily measured CA only at the aggregate level (e.

In a sample of adolescents (N = 97) and their parents, the current study examined parental depression symptoms, an observational measure of parenting, and parents' physiological reactivity during a dyadic conflict discussion task in association with adolescents' internalizing and externalizing psychopathology. Parental depression symptoms and harsh/insensitive parenting showed positive associations with youth psychopathology symptoms.
