Which type of intelligence involves solving problems by performing mental operations?

• A. Crystallized Intelligence
• B. Working Memory
• C. Processing Speed
• D. Fluid Intelligence

Answer: (D)

The main idea here is distinguishing how we reason with new, unfamiliar problems versus relying on what we already know. Solving problems by performing mental operations describes fluid intelligence—the ability to think logically, analyze novel situations, and use abstract reasoning to work through problems, independent of prior knowledge. It’s about how flexibly you can manipulate information in your mind to find solutions. Crystallized intelligence, by contrast, is about the knowledge and skills you’ve accumulated from experience and schooling. Processing speed refers to how quickly you can carry out cognitive tasks, which can affect problem solving but isn’t the specific type of intelligence being described. Working memory is the capacity to hold and manipulate information in the short term, a crucial cognitive function used during problem solving but not the broad intelligence type itself. So, the best match for solving problems through mental operations is fluid intelligence.
