Final answer:
Post-formal thinking is described as reflective and contextual thinking. It's a stage beyond Piaget's formal operational stage, involving decision-making based on specific contexts and blending logic with emotion.
Step-by-step explanation:
The statement that best describes post-formal thinking is D) Reflective and contextual thinking. Post-formal thinking is considered by many developmental psychologists as a fifth stage of cognitive development that goes beyond Piaget's formal operational stage. This advanced form of thinking involves making decisions based on situations and circumstances, integrating logic with emotion, and developing principles that are context-dependent. Adults in the post-formal thought stage can handle emotionally charged issues more adeptly than adolescents in the formal operational stage because they can draw on past experiences and recognize that different problems may require different solutions.
