Statement I - Parents and teachers have a highly significant impact on the maturation aspect of cognitive development.Explanation-Maturation is the process by which we change, grow, and develop throughout life.The process of increasing intellectual reasoning and ability whereby knowledge is acquired is typically associated with increasing chronological age prior to adulthood is known as cognitive maturation.Some important aspect of cognitive maturation is the processing of information, language development, reasoning skills, development of intellect and memory.Cognitive maturity comes from individual growth without any external stimuli.Hence, parents and teachers have a limited impact on the maturation aspect of cognitive development.Therefore, Statement I is incorrect.Statement II- Schemes are an organized system of actions or thoughts that allow us to mentally represent or "think about" the objects and events in our worldExplanation-.A scheme is a cognitive framework or concept that helps organize and interpret information.Schemes can be useful because they allow us to take shortcuts in interpreting the vast amount of information that is available in our environment.Hence, Schemes are an organized system of actions or thoughts that allow us to mentally represent or "think about" the objects and events in our world.Therefore, Statement II is correct.So, Statement I is false but Statement II is true
