How parental praise and criticism can shape a child's emotional resilience

Research reveals that repeated patterns of verbal attacks and conditional affection can undermine children’s self-worth and emotional stability, emphasising the importance of nurturing unconditional love and behaviour-focused guidance.

Parents are often told to avoid a handful of toxic phrases, as if child-rearing were a matter of memorising a banned-word list. The research is less theatrical and more useful than that. It points instead to two repeated habits that can do damage over time: verbal attacks on the child’s character and affection that seems to depend on performance. Everything else is more complicated, and far less absolute.

The first pattern is the one most people would recognise in principle, even if the details are more specific than they expect. In a 2013 study published in Child Development, Ming-Te Wang and Sarah Kenny found that harsh verbal discipline – shouting, cursing and insults aimed at the child rather than the behaviour – was linked with more depressive symptoms and conduct problems a year later in adolescents from 967 two-parent families. The study also found that parental warmth did not cancel out those effects, suggesting that affection elsewhere does not make contempt in the moment harmless. The relationship ran both ways, though: children with behaviour problems were also more likely to draw harsher discipline later, which makes the dynamic look cyclical rather than one-sided.

The second pattern is quieter but just as important. Psychologists call it parental conditional regard, meaning praise, affection or approval that is visibly tied to the child doing what the parent wants. Research by Avi Assor, Guy Roth and Edward Deci showed that this approach may secure short-term obedience, but it carries emotional costs. Children exposed to conditional regard were more likely to feel resentment towards their parents and to develop a more fragile sense of self-worth. A later study by Roth, Assor and colleagues found that conditional negative regard was associated with resentment, emotional dysregulation and academic disengagement in adolescents, while separate work suggested that both positive and negative forms of conditional regard can interfere with children’s emotional skills.

What makes this worth taking seriously is that it does not require overt cruelty. A cold response after a poor grade, praise that disappears when results slip or the repeated message that love must be earned can all send the same signal without a single explicit insult. Over time, that can teach a child not simply how to behave, but how to doubt their own value. The danger is not only hurt feelings in the moment; it is the slow shaping of motivation around fear of disapproval rather than confidence, curiosity or internal standards.

None of this means parents need to speak perfectly, or that a single bad exchange is a catastrophe. The studies in this area are about patterns, not isolated lapses, and much of the evidence is based on self-report and specific family samples. Firm boundaries are not the same as verbal aggression, and high expectations are not the same as making affection conditional. The crucial distinction is between correcting behaviour and attacking identity, or between guiding a child and making love feel transactional.

For parents who recognise one of these habits in their own home, the answer is not guilt but repair. Taking a step back after a harsh moment, acknowledging the loss of temper and reconnecting can all help restore a sense of safety. And if a family feels stuck in a cycle of conflict, or if a child’s mood or behaviour is becoming a concern, evidence-based parenting support or a child mental health professional is a more useful response than searching for a perfect script. The research does not say parents must never fail. It says children are more likely to thrive when criticism is aimed at actions, not character, and when love is not made to look like something that has to be earned.
