Answer:
Assimilation
Step-by-step explanation:
According to the concept of Assimilation by Piaget's.
It can be termed as the part of the adaptation process in which a person is tend to incorporate new experiences into their life and also sometimes are expected to combine the new experiences with the older ones and thus forming a whole new experience. It can normally be misjudged by the change in the behaviours of the people as they all of a sudden start doing something that they do not generally/usually do.
The children in their early age are always assimilating with the surroundings as they tend to learn and behave differently every other day. It is a part of growing up as the cognitive abilities of a person change constantly.
Therefore, the Louis's dribbling of the new ball represents his Assimilating behaviour.
