Which of the following is a sign related to problem solving in intellectual disability?

• A. Developmental delays in motor milestones
• B. Having trouble solving problems
• C. Not understanding how to pay for things
• D. Having trouble understanding social rules

Answer: (B)

Problem solving is a key component of adaptive functioning, which is often impaired in intellectual disability. When someone has trouble solving problems, it signals difficulties with planning, trying different strategies, and evaluating outcomes—core aspects of how a person adapts to new tasks and challenges in daily life. This is exactly what problem-solving signs look like in this context: slower, less efficient or less successful attempts to identify and carry out steps to reach a solution.

The other signs point to different domains. Delays in motor milestones reflect motor development issues, not cognitive problem-solving. Not understanding how to pay for things involves practical math and financial concepts, a specific functional skill but not the core process of solving problems. Trouble understanding social rules indicates difficulties in social cognition and norms, which is a separate adaptive domain. So, trouble solving problems best captures the issue of problem-solving ability.
