What do children do in the Digit Span task that tests their memory?

In the Digit Span task, children are assessed on their working memory capabilities by repeating back sequences of numbers presented to them. This task specifically measures auditory memory and attention by requiring children to listen to a series of digits and then accurately reproduce them in the same sequence or in reverse order. It challenges their ability to retain and manipulate information over a short period, which is crucial for cognitive development and functioning.

The other options do not align with the purpose of the Digit Span task. Matching pictures to numbers, retelling stories, and balancing weights do not specifically focus on the core memory aspects that the Digit Span task evaluates. Therefore, the focus on writing digits in various specified orders is fundamental to the memory assessment that the Digit Span task is designed to perform.
