4 Cost-Free Ways for Parents to Boost Their Child’s IQ

A child's intelligence is influenced both by genetic factors and the nurturing provided by parents. If these four principles are instilled in children from a young age, they will grow up to be highly accomplished individuals.


Allow your child to play freely outdoors

Neuroscience researchers Marc Berman, John Jonides, and Stephen Kaplan from the University of Michigan have demonstrated the benefits of nature exposure on children’s cognitive abilities. They have shown that walking in the park or even looking at nature paintings can improve memory and attention by up to 20%.

Allow your child to play smart video games

Scientists from the University of Rochester in the United States have discovered and proven that action video games can enhance a player’s ability to make quick decisions. Players become highly alert to what is happening around them. This helps them perform better and improve essential skills for everyday activities like multitasking, driving, reading small print, keeping track of friends in a crowd, and navigating routes. Moreover, their brains gather information efficiently, enabling them to make well-timed decisions.

Expose your child to music

Professor Dennie Palmer Wolf, an expert in the study of artistic development in young children at Harvard University, collaborated with Carnegie Hall in Manhattan, USA, to conduct a study called “Why Music Matters” on the role of music in a child’s development.

A child who can feel music, such as tapping their feet, clapping, swaying, and moving to the rhythm, can develop the best coordination of body movements. Even simple games or songs help develop the connection between the mind and body. If a child continues to play musical instruments as they grow older, this ability will continue to develop. These factors constitute important connections between many areas of the brain, helping individuals carry out complex actions and interactions.

Through observing music and dance classes, researchers have discovered that children who engage in artistic activities develop positive emotions and have better emotional control.

In addition, music is also beneficial for a child’s communication and interaction with peers. Music with rhythm and tempo, lyrics and refrains helps children understand the rules of social life. Furthermore, music can shape the social interaction structure for children who have experienced psychological trauma or autism.

Lastly, music brings joy and excitement. These positive emotions are crucial aspects of humanity, attracting others, improving mood, and reducing sadness.

Talk to your child every day

The Hart & Risley study in 1995 and the subsequent LENA validation study in 2008 showed differences in language skills between children raised in language-rich environments and those in language-deficient environments.

The Hart & Risley study found that “the more parents talk to their children, the faster their vocabulary develops, and the higher their IQ test scores are after the age of 3.” Children with talkative parents hear 45 million words in their first 4 years of life, while children with less talkative parents only hear 13 million words. Therefore, after 4 years, there is a difference of 30 million words.

The LENA study showed that children aged 0-4 years with parents who talk a lot and have more conversational interactions develop better language skills. The most intelligent children – about 10% – hear more than 191 words per day and engage in more than 18 conversations per hour compared to less intelligent children.
