Past research has demonstrated barriers to IPV victims seeking legal intervention including mistrust of the court system generally, extensive and confusing legal processes and procedures, and failure of the courts to assess more invisible forms of abuse (Calton et al., 2017; Cerulli et al., 2015; Cuomo & Dolci, …

Self-Regulation In Children With Fragile X Syndrome: Biobehavioral Underpinnings, Familial Predictors, And Outcomes, Erin Evelyn Hunt

Theses and Dissertations

Self-regulation is a multifaceted construct that occurs on biological, cognitive, emotional, and behavioral levels. Self-regulatory abilities typically emerge in the first years of life and continuously develop through early adulthood. There is considerable interindividual variability in developmental trajectories of self-regulation which are associated with numerous adaptive and maladaptive outcomes. Factors influencing the development of self-regulation include interacting genetic and social environmental factors. Given the high heritability of self-regulation, within-family associations are common.

Individuals with Fragile X syndrome (FXS), an inherited, single-gene neurodevelopmental disorder, have heightened vulnerability for self-regulation deficits that are evident in early infancy; however, the developmental trajectories and …
