MoCA Digit Span (Forward and Backward)

Question 1

How many digits are in the forward digit span sequence used in the MoCA?

Accepted Answer

5 digits

Answer

The MoCA forward digit span uses a 5-digit sequence (e.g., 5-4-2-1-8). The examinee must repeat the digits in exactly the same order presented. This tests auditory registration and immediate attention span.

Question 2

How many digits are in the backward digit span sequence used in the MoCA?

Accepted Answer

3 digits

Answer

The MoCA backward digit span uses a 3-digit sequence (e.g., 7-4-2). The shorter length compared to the forward span reflects the added working memory demand of reversing the sequence.

Question 3

How should the MoCA digit span sequences be read to the examinee?

Accepted Answer

Read aloud at 1 digit per second in a clear, steady voice

Answer

Standardized MoCA administration requires the examiner to read the digit sequence aloud at exactly one digit per second in a clear, even tone. This pacing ensures consistency across administrations and examiners.

Question 4

Under which MoCA domain do both forward and backward digit span tasks fall?

Accepted Answer

Attention

Answer

Both forward and backward digit span tasks are classified under the Attention domain of the MoCA. Forward span tests auditory attention and immediate registration; backward span additionally taps working memory through the requirement to mentally reverse the sequence.

Question 5

How many total points can be earned from both digit span tasks combined on the MoCA?

Accepted Answer

2 points total

Answer

Each digit span task is worth 1 point (forward = 1 point, backward = 1 point), for a combined maximum of 2 points within the Attention domain. Each is scored pass/fail based on whether the complete sequence is reproduced correctly.
