Environmental stimulation during childhood often contributes to the development of intelligence by altering the circuitry of the brain. this alteration illustrates

Neural Plasticity

Explanation:

The ability to change the form and function of the neurons in response to the changes that takes place in the environment is termed as neural plasticity. Due to neural plasticity, the brain has the capability to change throughout the life of an individual. Neural plasticity is important for the optimum working of the brain. The environmental stimulation that takes place during childhood alters the circuitry of the brain and hence, contributes to the intelligence of the child and this alteration in the circuitry with respect to he environmental stimulation is an example of neural plasticity.
