Process of categorizing objects, events, or concepts based on shared attributes?

• A. Conservation
• B. Classification
• C. Industry vs. Inferiority stage
• D. Formal operation stage

Answer: (B)

Classification is the process of grouping objects, events, or concepts based on shared attributes. This cognitive skill lets learners organize information into categories—like animals, colors, or shapes—and recognize hierarchies such as dogs and cats being animals, and animals being a broader category. It typically emerges as children move into concrete operational thinking, when they can consider multiple features and subcategories rather than just one attribute. This differs from conservation, which is about understanding that quantity stays the same despite changes in appearance, and from the ability to think abstractly in the formal operational stage. It’s also not a psychosocial developmental stage, but a cognitive skill crucial for logical thinking and later reasoning.
