Which construct measures the capacity to maintain and manipulate information in temporary storage during problem solving?

• A. Working Memory
• B. Processing Speed
• C. Verbal Comprehension
• D. Visual-Spatial Reasoning

Answer: (A)

The main concept being tested is the ability to hold and actively manipulate information in temporary storage while solving problems. This is what working memory does: it provides a mental workspace where you keep intermediate data, rules, and steps in mind and then transform them as you plan and carry out a solution. It’s not just about storing information briefly; it’s about processing and updating it in real time as you work through a task. That makes it the best fit for describing the capacity to maintain and manipulate information during problem solving. Processing speed is about how quickly you can perform cognitive operations, which affects pace more than the actual capacity to hold and manipulate information. Verbal comprehension centers on understanding language content, which helps with language-based tasks but doesn’t pinpoint the active storage-and-manipulation system. Visual-spatial reasoning concerns how you mentally manipulate visual and spatial information, a component of working memory, but the broader concept of holding and actively working with information across tasks is best captured by working memory itself.
