How many sections are there in the Digit Span subtest?

The Digit Span subtest consists of two primary sections: Digit Span Forward and Digit Span Backward. Digit Span Forward involves the child repeating a sequence of numbers in the same order they are presented. This section primarily assesses attention and short-term auditory memory. On the other hand, Digit Span Backward requires the child to repeat the numbers in reverse order, which evaluates not only memory but also the ability to manipulate information, indicating working memory capacity.

In addition to these two sections, there is also a lesser-known variant sometimes included called Digit Span Sequencing, where the numbers must be repeated in ascending order rather than the order presented. While it's commonly viewed that the main sections of the subtest are forward and backward, some interpretations of the structure of this assessment can refer to the third section (sequencing) as a component of the Digit Span evaluation process.

Thus, in a broader understanding that includes the lesser-seen section, the correct interpretation of the subtest could lead one to perceive there are three sections overall when counting the main components plus sequencing. Hence, indicating three as the correct response captures a more comprehensive view of the Digit Span subtest.
