Answer:
A. preoperational stage
Explanation:
Cognitive development can be defined as the development of thought processes, skills, knowledge and problem-solving abilities from infancy through adulthood.
Jean Piaget was a developmental biologist and psychologist who worked extensively on cognitive development in infants and teenagers; these are judgement, knowledge and thoughts.
Jean Piaget's stages of cognitive development in an ascending order are;
I. Sensorimotor: this is between 0 - 2 years (18 - 24 months) where the child exhibits object permanence.
II. Preoperational: this is age 2 - 7 years where the child acts in an egocentric manner.
III. Concrete operational: this is age 7 through age 11 and the child thinks logically at this stage.
IV. Formal operational: this is from adolescence (11 years) through adulthood and focuses on logically thinking about abstractions.
Hence, the preoperational stage in Piaget's cognitive development theory reflects a child's egocentrism, which leads the child to act in a self-centered fashion.
