Which task is used as an alternative attention task in this set?

• A. Spelling backwards
• B. Serial sevens
• C. Digit span
• D. Remote memory

Answer: (A)

Attention testing in cognitive screens often uses two forms of the same domain to gauge concentration and working memory, giving clinicians a flexible way to assess a patient without relying on a single method. Spelling backwards is used as the alternative attention task because it challenges attention and working memory through language processing rather than arithmetic. The patient must hold the word in working memory and reverse its order, which taps sustained attention and cognitive control in a different way than counting backward by sevens. This makes it a good substitute when the arithmetic attention task is difficult for the patient or could bias the result.

Other options target different abilities: the serial subtraction task is the more typical calculation-based attention measure; digit span assesses immediate memory and attention but in a way focused on briefly storing and repeating sequences; remote memory evaluates long-term recall rather than attention.
