Studies indicate that 30-43% of children in the United States have witnessed some form of physical violence between their parents. This violence can have a profound effect on the cognitive and emotional development of preschool children. Studies suggest that younger children may be more vulnerable to the effects of witnessing domestic violence than older children (Johnson & Lieberman, 2011), so it is very disturbing to recognize that young children are more likely to witness incidents of violence compared to older children (Ybarra, Wilkens, & Lieberman, 2011). Witnessing these acts of violence has a detrimental effect on cognitive development, emotion regulation, and internalizing and externalizing behaviors in preschool children (Lieberman, 2011; Ybarra, Wilkens, & Lieberman). Studies show that dysfunctional development can be discouraged through a positive relationship with mother and child, and that resilience is possible if there is a nurturing relationship in which the mother is attuned to her child's emotions. Having at least one parent who engages in physical violence, psychological aggression or high levels of other conflict behaviors towards one's adult partner has a positive correlation with the child's behavioral difficulties and young children are seriously affected by violence within their families (Ybarra, Wilkens and Lieberman). One of the biggest obstacles faced by preschoolers who witness domestic violence is their reduced verbal ability. Three- to five-year-olds exposed to domestic violence show lower verbal skills than their unexposed peers. There is a 4% change in the IQ of young children when they are exposed to domestic violence, which corresponds to an average reduction of eight points.
