Answer :

At age of 5-7 years, children begin to realize that some things should be remembered, and they began to use simple strategies, primarily rehearsal.

  • Children start to employ basic tactics, mostly rehearsing, once they learn that some things should be recalled (repeating an item again and again). Although this is not a highly effective tactic, repetition leads to automatization.
  • According to Piaget, the Preoperational Stage relates to the first few years of childhood. According to Piaget, this period lasts from the age of two to seven years. Children who are still in the preoperational stage use symbols to represent words, images, and concepts, which encourages them to engage in pretend play.
  • The study of cognitive development focuses on how a child grows in terms of information processing, conceptual resources, perceptual skill, language learning, and other characteristics of the fully developed adult brain and cognitive psychology.

Thus the answer is 5-7 years.
