Harsh physical punishment of children may reduce the amount of grey matter in some area of the prefrontal cortex, resulting in a variety of mental health disorders.
How to discipline the next generation is a hotly debated topic. In 2012, a national survey showed more than half of women and three-quarters of men in the United States believe a child sometimes needs a "good hard spanking."
Science tells a different story. Researchers say physical punishment actually alters the brain -- not only in an "I'm traumatized" kind of way but also in an "I literally have less gray matter in my brain" kind of way.
"Exposing children to HCP (harsh corporal punishment) may have detrimental effects on trajectories of brain development," one 2009 study concluded.
Harsh corporal punishment in the study was defined as at least one spanking a month for more than three years, frequently done with objects such as a belt or paddle. Researchers found children who were regularly spanked had less gray matter in certain areas of the prefrontal cortex that have been linked to depression, addiction and other mental health disorders, the study authors say.
