A popular working memory test that is used in many cognitive and neuroscience research labs. Repeat the sequence of numbers shown during the test. To make it more interesting (and difficult), gradually increase the Span, which starts out at 5, and change to Fast test speed. You can also switch from Forward to Reverse, which means entering the number sequence in **reverse** order.

Working Memory Definition
Working memory is the capacity to hold small amounts of information in an active, easily accessible state, usually for less than 30 seconds at a time. Examples include keeping a new phone number in working memory long enough to dial the number, and keeping a new, important meeting date & time in your active memory long enough to write it down.
