Final answer:
Critical periods are specific time frames in an individual's life when they are highly receptive to learning or developing certain skills. The duration of critical periods can vary depending on the skill or ability being acquired.
Step-by-step explanation:
Critical periods are specific time frames in an individual's life when they are highly receptive to learning or developing certain skills. These periods are characterized by increased plasticity and are crucial for the acquisition of particular abilities.
An example of a critical period is the development of language skills in children. Between the ages of six and ten, children undergo important cognitive changes that allow them to develop more mature ways of thinking and improve their language skills.
The duration of critical periods can vary depending on the skill or ability being acquired. Some critical periods, such as the acquisition of language, tend to last until early adolescence, while others, like the development of vision, may occur during infancy.
