Which cognitive development stage continues into early adulthood, supporting abstract reasoning and hypothesis testing?

• A. Sensorimotor stage
• B. Concrete operational stage
• C. Formal operational stage
• D. Postformal stage

Answer: (C)

The key idea is the ability to think abstractly and test ideas systematically. In Piaget’s framework, the formal operational stage brings on abstract reasoning and hypothetical-deductive thinking. This isn’t tied to concrete objects; it lets you consider possibilities, form hypotheses like “If I change this variable, that outcome will occur,” and reason through consequences without needing physical objects to manipulate. This capacity starts in adolescence and continues into early adulthood, enabling sophisticated problem solving, planning, and scientific-minded thinking. Sensorimotor reasoning is tied to based-on-sensory-motor actions and develops in infancy. Concrete operational thinking handles concrete, tangible problems and rules of reversibility but not abstract concepts. Some theories extend thinking into adulthood with a postformal stage, which describes more flexible, integrated approaches to real-world problems, but the classic stage associated with abstract reasoning and hypothesis testing that lasts into early adulthood is the formal operational stage.
