Final answer:
According to information-processing theorists, abstract thinking is a cognitive capability that develops earlier than Piaget thought, emerging during adolescence.
Step-by-step explanation:
According to information-processing theorists, some cognitive capabilities are believed to be more advanced and acquired earlier than Piaget thought. One of these capabilities is abstract thinking, which allows individuals to consider multiple points of view, imagine hypothetical situations, and form new ideas. Piaget referred to this stage as formal operational thought, which he believed develops between 11 and 20 years old. However, information-processing theorists suggest that abstract thinking emerges earlier during adolescence.
