If you are working through a WAIS-5 report, whether it is your own or a family member’s, the Working Memory Index describes a kind of mental juggling that touches a lot of everyday tasks. This guide explains what it measures, how to read the number, and what it does and does not tell you, in plain language.
The Quick Answer
The Working Memory Index, usually shortened to WMI on a report, is a measure of how well a person holds information in mind and works with it for a short time, the mental equivalent of keeping several things on the desk at once. It is one of five main index scores on the WAIS-5. On its own it describes one slice of thinking, not a person’s overall ability, and no single index decides what a report means.
