Over 50 years of research illustrates how corporal punishment violates not just children's right to freedom from all violence, but also their rights to health, development, and education. Corporal punishment, defined as the "intentional infliction of physical pain by any means for the purpose of punishment, correction, discipline, instruction, or any other reason," has been identified as a public health crisis due to its strong evidence of negative impacts and very high prevalence. The relationship between corporal punishment in educational settings and mental health outcomes represents a significant concern for child development and well-being, with implications that extend far beyond the school environment.
Enormous numbers of children experience corporal punishment in their homes, schools, care and work settings and the penal system in countries across world regions. The high prevalence of corporal punishment in schools is particularly concerning given the educational environment's role in child development. The legality of corporal punishment undermines child protection by reinforcing the idea that a certain degree of violence against children is acceptable, which may contribute to normalization of such practices in educational settings. This normalization creates a cycle where violence becomes an acceptable tool for behavior control, potentially affecting multiple generations of children.
Research has established strong links between corporal punishment and negative impacts on mental health. These associations include behavior disorders, anxiety disorders, depression, hopelessness, and low self-esteem. Later studies have confirmed these connections and found further links with suicide attempts, alcohol and drug dependency, hostility and emotional instability, self-harm and other mental health problems. The emotional trauma associated with corporal punishment may manifest in various psychological symptoms that affect academic performance, social relationships, and overall quality of life for students in educational settings.
Importantly, the increased risk for these mental health conditions continues into adulthood, suggesting that the effects of corporal punishment during school years may have lifelong consequences. The cumulative impact of experiencing violence in what should be a safe learning environment can disrupt normal emotional development and create patterns of negative self-perception and maladaptive coping mechanisms that persist long after the school years have ended.
Recent research has begun to uncover the neurodevelopmental mechanisms underlying these mental health impacts. A study led by Kreshnik Burani and Greg Hajcak at Florida State University examined how corporal punishment affects neural measures of error and reward processing in 149 adolescents aged 11 to 14. The researchers conducted a longitudinal study using EEG to examine the neural underpinnings of the experience of corporal punishment and its downstream consequences.
The researchers found that adolescents who received physical punishments exhibited larger neural responses to errors and blunted responses to rewards compared to their peers. This altered brain activity represents a neurodevelopmental pathway through which corporal punishment may increase risk for mental health disorders. Specifically, the study links corporal punishment to increased neural sensitivity to making errors and decreased neural sensitivity to receiving rewards in adolescence.
These findings suggest that corporal punishment might alter specific neurodevelopmental pathways that increase risk for anxiety and depression by making children hypersensitive to their own mistakes and less reactive to rewards and other positive events in their environment. The increased neural response to errors is associated with anxiety and risk for anxiety, whereas decreased neural response to rewards is related to depression and risk for depression. This research provides new insights into the neural systems that may be affected by corporal punishment and the mechanisms that may underlie its adverse effects on mental health.
Cameron Carter, MD, Editor of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, noted that "Using EEG, this study provides new insights into the mechanisms that may underlie the adverse effects of corporal punishment on mental health in children as well as the neural systems that may be affected." The work provides new clues as to the neural underpinnings of depression and anxiety and could help guide interventions for at-risk youth.
The negative effects of corporal punishment on individual children and adults contribute to broader societal impacts. Research suggests that the more a society approves of violence for certain purposes, the more likely it is that violence will be used for other purposes as well. This normalization of violence in childhood may perpetuate cycles of aggression and maladaptive coping strategies that extend into adult relationships and parenting practices.
Corporal punishment in childhood is associated with adulthood health issues including developing cancer, asthma, alcohol-related problems, migraine, cardiovascular disease, arthritis and obesity as an adult. These physical health consequences, combined with the persistent mental health impacts, create a significant public health burden that could be reduced through the elimination of corporal punishment practices. The connections between corporal punishment of children and wider violence in society suggest that addressing this issue may have far-reaching benefits for community health and safety.
Considering the strong evidence of the many negative impacts of corporal punishment combined with its very high prevalence, prohibiting and eliminating corporal punishment is recognized as a critical preventative health strategy. This approach can be understood as a low-cost public health measure critical in preventing injury and disability in childhood, emotional trauma and mental illness, anti-social behaviour and aggression, and promoting optimal welfare, development and educational outcomes for children, which last throughout life.
Evidence suggests that eliminating violent punishment of children may reduce other forms of violence in society, including domestic, intimate partner and gender-based violence, and diminish drug and alcohol abuse and suicide in adulthood. The implications for public health systems are significant, as addressing corporal punishment represents an opportunity to prevent multiple adverse outcomes across the lifespan. The legality of corporal punishment undermines child protection efforts by creating a legal distinction between violence against children and violence against adults, which reinforces power imbalances and may prevent children from seeking help or reporting abuse.
The prohibition and elimination of corporal punishment can be understood as a critical preventative health strategy that addresses the root causes of multiple negative health outcomes. By removing this form of violence from educational settings and other environments where children spend significant time, societies can create safer, more nurturing spaces that support healthy neurodevelopment and emotional well-being.
The research clearly demonstrates that corporal punishment in schools has significant negative impacts on mental health, both immediately and across the lifespan. The neurodevelopmental changes identified in recent studies provide biological mechanisms for the increased risk of anxiety and depression observed in adolescents who experience corporal punishment. Given these findings, the elimination of corporal punishment in educational settings represents a critical public health priority with potential benefits for individual well-being and broader societal outcomes.
The complex emotional experience evoked by corporal punishment, particularly when inflicted by authority figures such as teachers, can create lasting psychological effects that extend beyond the immediate moment of punishment. The altered neural processing of errors and rewards identified in research may contribute to the development of anxiety disorders and depression, which are among the most common mental health conditions affecting adolescents.
As public health awareness grows regarding the risks associated with corporal punishment, alternative approaches to discipline that promote positive behavior without violence are increasingly being recognized as both more effective and more aligned with children's rights and well-being. The evidence supports a shift away from punitive measures that cause physical and emotional harm toward educational environments that foster healthy development, emotional regulation, and positive social learning.
