Selective mutism is a mental disorder. It refers to children who have acquired normal language skills but remain silent in certain social situations due to psychological stress. Its essence lies in social dysfunction rather than language impairment.This condition typically emerges between ages 3 and 5, with girls being more commonly affected. During periods of silence, children may use gestures, nodding, or shaking their heads to express opinions, or communicate solely with words like "yes," "no," or "want." Occasionally, writing serves as their means of communication. Refusal to speak usually occurs in school settings or in the presence of strangers.A minority exhibit the opposite pattern, speaking at school but remaining silent at home. Some children refuse to speak with adults, while others communicate only with children or familiar individuals.Why Do Children Develop Selective Mutism? (Public Health Network) Behavioral experts suggest that selective mutism in children represents a coping mechanism for navigating social environments. Silence serves as a primary self-protective tool, particularly for those who haven't yet learned to adapt to environmental changes. When a child perceives an environment as triggering anxiety, silence often becomes their most immediate instinctive response.
If your child exhibits the following five symptoms, they may have selective mutism:
1. Inability to speak in situations requiring verbal communication, while speaking normally in other settings;
2.This condition persists for over a month;
3. There are no speech impairments, and the issue isn't caused by speaking a foreign language (or a different dialect);
4. The condition arises due to life changes such as starting school, changing schools, moving, or social interactions affecting the child.
5. The child does not have conditions like autism, schizophrenia, intellectual developmental delays, other developmental disorders, or mental illnesses.
Why do children become "silent"? In extremely rare cases, genetic factors may be involved. Hysterical disorders, affective psychoses, and schizophrenia may also present with mutism. For most children, this is significantly related to excessive indulgence and overprotection by parents within the family.
