Reversibility ability develops in the stage:

Question

Accepted Answer

Reversibility ability develops in the stage:

1. **Concrete operational stage**: The concrete operational stage, which typically occurs between the ages of 7 and 11, is characterized by the development of logical thinking and the ability to perform operations mentally. One of the key cognitive abilities that emerge during this stage is reversibility. Reversibility refers to the understanding that objects or numbers can be changed and then returned back to their original condition. For example, a child understands that if you have a certain amount of liquid in a short, wide glass and pour it into a tall, narrow glass, the amount of liquid remains the same. This ability to mentally reverse actions is a hallmark of the concrete operational stage, making Option 1 the correct answer.

2. **Preoperational stage**: The preoperational stage occurs from approximately ages 2 to 7. During this stage, children are developing language and beginning to engage in symbolic play, but they lack the ability to perform operations or understand concepts like reversibility. Their thinking is more intuitive and egocentric, meaning they have difficulty seeing things from perspectives other than their own. Therefore, reversibility does not develop during the preoperational stage, making Option 2 incorrect.

3. **Formal operational stage**: The formal operational stage begins around age 12 and continues into adulthood. In this stage, individuals develop the ability to think abstractly, reason logically, and use deductive reasoning. While these are advanced cognitive abilities, the concept of reversibility is already established by this stage. Thus, the formal operational stage is not where reversibility first develops, making Option 3 incorrect.

4. **Sensory motor stage**: The sensory motor stage spans from birth to about 2 years of age. During this period, infants learn about the world through their senses and actions. They develop object permanence and begin to understand that objects continue to exist even when they cannot be seen. However, the concept of reversibility is far too complex for this stage, as infants are primarily focused on immediate sensory experiences and motor activities. Therefore, Option 4 is incorrect.

In conclusion, the concrete operational stage is the correct stage where reversibility ability develops, as children begin to understand and apply logical operations to concrete objects and events.
