Research: Hitting Children Has No Benefits, Only Negative Consequences

On International No Hit Day, a growing body of scientific evidence reinforces a clear message: physical punishment is detrimental to child development and fails to achieve its intended disciplinary goals. This aligns with the growing global consensus against corporal punishment, urging parents and caregivers to seek alternative, non-violent methods of guidance.

Hitting children cannot achieve the purpose of discipline and only brings negative effects.

Extensive research, including a meta-analysis of nearly 160,000 children, has consistently demonstrated a strong correlation between spanking and a range of negative consequences. These include increased behavioral problems, defiance, aggression, and impaired cognitive development. Crucially, the studies found no evidence that physical punishment yields any positive effects on a child's behavior or well-being. The research even indicates that the distinction between "mild spanking" and "physical abuse" is statistically insignificant in terms of harmful impact, suggesting that any form of physical punishment carries inherent risks.

Further neurological studies using MRI scans have revealed that children subjected to frequent corporal punishment exhibit measurable differences in brain structure. Specifically, reductions in gray matter volume in the prefrontal cortex—a region vital for emotional regulation, impulse control, and social cognition—have been observed. This is particularly concerning as the very purpose of discipline is to help children develop self-control, a capacity that physical punishment appears to undermine.

The research shows that hitting children is significantly associated with negative consequences, and no indicator shows that 'hitting' can bring positive effects.

Experts like Dr. Su Yi-ning, a prominent obstetrician and gynecologist, emphasize that the immediate "effectiveness" of hitting or yelling stems from activating a child's fear response. This teaches them to avoid punishment in the moment but does not foster genuine understanding of right and wrong. Instead, children may learn to conceal their actions, become more deceptive, or develop a heightened state of alert, perceiving their parents as a source of threat rather than safety.

The purpose of hitting children was originally to make them 'learn to control themselves,' but in reality, what you hit away is the part of their brain that 'they use to control themselves.'

The scientific community's findings are unequivocal: physical punishment does not lead to better behavior; it often exacerbates behavioral issues and damages the parent-child relationship. While the goal of discipline is to guide children toward positive behavior, the research suggests that hitting children primarily serves to vent adult frustration. International No Hit Day serves as a crucial reminder that even a single day of refraining from physical punishment is a vital first step towards fostering healthier, more constructive parent-child interactions.

The research repeatedly tells us the same thing: hitting does not make children better, it only makes them harder to teach.
