Mental or Cognitive development: – The meaning of cognition is to know, perceive or comprehend. Hence, it would mean the development of the capability of knowing and understanding things over time, again in interaction with an environment.
Cognition also involves the ability to construct mental images based on one’s own imaginations and reasoning.
These mental images are also constructed by an individual after examining the surroundings around him/her.
Thus, every individual has a unique model of his imagination based on his understanding of the unique process of observation.
This is how a learner tries to learn about the world around him.
