Learning is a dynamic activity and it involves the active presence of both mind and body. The factors that affect the process of learning, especially of school children, are mostly the factors that relate to their mind or psyche. The minds of the children are shaped or affected mostly by the factors in their family as the children’s world is very much confined to the family. The family background and the experiences of children in the family or neighbourhood plays a vital role in setting their mind towards learning.In this paper, we analyse several factors which are the adverse childhood experiences that affect the learning process of school children and determine the most important of them. For this purpose, fuzzy cognitive maps (FCM) is modified with Pythagorean fuzzy numbers as edge weights. A new simulation process is proposed and executed. The fixed points obtained through this process indicates the dominant factors that affect learning of school children.
