Hello Kadna :) It's nice to see you here. Good opportunity to thank you for your support (including re-esteeming my last post)!
behaviour can also arise, be sustained or modified by means of the consequences that follow it
The consequence meaning either reinforcement or punishment. It has been largely demonstrated that this sort of consequence does either give rise to, maintain or alter behaviour :D. With punishment being, in Skinnerian terms, an event that follows an action that leads to the decreased frequency of it.
I do agree that when it comes to children a more productive way to inform them about rules and norms is through reinforcement. Because, as observed in the article, punishment is limited in the way that only tells them what not to do, and often fails to guide them towards the desired conduct. Children more than any one are the ones who need information and guidance. Through kindness and compassion that is :)
The little ones who are under your care are indeed privileged ones!
