The digit span test primarily assesses which cognitive function?

• A. Attention and concentration
• B. Language fluency
• C. Long-term memory
• D. Executive planning

Answer: (A)

The main idea assessed by the digit span test is attention and concentration. It requires you to listen to a sequence of digits and reproduce it, which taps the ability to sustain focus and hold information in short-term memory. The forward version emphasizes pure attentional capacity and immediate memory, while a backward version adds mental manipulation and taps working memory (an aspect of executive function). However, the test’s primary purpose is to gauge attentional capacity, not language fluency, long-term memory storage, or planning.
