Signs of Low Intelligence in Children

Children with delayed intellectual development, also known as low intelligence quotient (IQ), may exhibit the following characteristics: 1. Delayed motor development: This is mainly manifested by later achievement of common movements such as walking and running compared to peers of the same age. Prominent features include unsteady gait, poor balance, and a tendency to fall easily. 2. Delayed language development: Normal infants can usually babble and imitate sounds at 7–8 months of age, and begin to consciously say "mama" or "dada" at 1 year old, as well as understand simple conversations. However, infants with low intelligence often experience delayed speech development. 3. Poor memory: Infants with low intelligence generally demonstrate reduced perception of their surroundings and may require repeated exposure to barely remember things around them. 4. Abnormal facial features: Compared to typical children, infants with low intelligence may appear expressionless, with specific manifestations including limited facial expressions, drooling, and a large tongue. 5. Low hearing and vision: Conditions such as myopia, total deafness, or hearing impairment may occur. These deficiencies can reduce the child's perceptual abilities, which, in turn, can significantly affect the child's communication skills. Over time, the child may develop significant communication difficulties.
