What are the key milestones in cognitive development?

Cognitive development refers to the growth and progression of intellectual abilities and processes as individuals mature. It involves how children think, understand, learn, and solve problems. There are several significant milestones in cognitive development that can be observed in children:

1. Sensorimotor Stage (birth to 2 years): During this stage, infants learn about the world through their senses and actions. They develop object permanence, the understanding that objects still exist even when they are out of sight.
2. Preoperational Stage (2 to 7 years): Children begin to represent things with words and images, but they often struggle with logical reasoning. Their thinking is egocentric, meaning they have difficulty taking others' perspectives into account.
3. Concrete Operational Stage (7 to 11 years): At this stage, children become more capable of logical thinking and conservation, understanding that certain properties of objects remain constant despite changes in appearance.
4. Formal Operational Stage (11 years onward): During adolescence and beyond, individuals develop abstract reasoning abilities. They can think hypothetically and engage in deductive reasoning.

These milestones are general guidelines, and every child develops at their own pace. However, understanding these stages can help caregivers, educators, and psychologists gauge a child's cognitive growth and provide appropriate support and stimulation.
