Watch (and listen) to a toddler as s/he plays.
You may often overhear her actually telling herself what to do (“I’m going to get my toolbox. Then I am going to fix my peppa car”).
In the above example the verbal instructions to self allows the child to gather and plan (cognition) her ideas (thoughts) and behaviour (self-regulation) and then accordingly put them into action.
Language thereby enables the following:
1. Be more clearly understood by others
Eg: “I want bread and jam. I will spread the jam myself 1 Please Mumma”
2. More tangibly understands events around.
Eg: “The clouds are bursting, and it is dark outside. It is going to rain mama”
3. Increases adaptation and coping skills.
Eg: “My tummy is hurting. I will eat my chocolate later”. And keeps his chocolate in the fridge.
4. Picks up non-verbal communication.
Eg: Dad: Smriti did you see Vinay covering his face when you threw the ball at him. It is because he was afraid that he might get hurt. Let’s be gentler at throwing. Come let me show you.
