Can frequently yelling at and scolding children affect their intelligence?

Generally speaking, whether frequent yelling and scolding negatively affects a child's intelligence depends on specific factors such as the frequency, intensity, and duration of such behavior. The detailed analysis is as follows:

Occasional and mild reprimands used as reminders, without personal attacks or prolonged stress, do not adversely affect a child's intelligence. In such cases, the criticism serves more as immediate guidance. The child's emotional fluctuations are brief and they can quickly return to a calm state, with no disruption to brain cognitive functions. On the contrary, correcting behavior in this way may help establish awareness of rules.

Long-term, frequent, and intense yelling and scolding, especially when accompanied by humiliation, threats, or other negative emotional outbursts, can keep children in a persistent state of anxiety and fear. This condition consumes cognitive resources in the brain, impairing attention, memory, and mental flexibility. It may also suppress curiosity and motivation to learn, indirectly hindering cognitive development and thereby negatively affecting intellectual performance.

When communicating with children, try to remain patient, calmly explain issues, and express expectations clearly. Pay close attention to the underlying needs behind their behaviors, offering sufficient understanding and encouragement, so that children can grow up in a safe and supportive environment. When feeling emotionally overwhelmed, take a brief pause to calm down before resuming communication, avoiding actions driven by anger. This approach better protects the child's psychological well-being and creates favorable conditions for healthy cognitive development.
