Final answer:
The Working Memory Index (WMI) in the WISC-V measures an individual's ability to hold and manipulate information in short-term memory while performing cognitive tasks. It includes subtests assessing auditory and visual working memory and working memory span. Primary capacities associated with working memory include attention control, inhibition, and task switching.
Step-by-step explanation:
Working Memory Index (WMI) Primary Capacities
The Working Memory Index (WMI) is one of the five indices in the Wechsler Intelligence Scale for Children - Fifth Edition (WISC-V). It measures an individual's ability to hold and manipulate information in short-term memory while performing cognitive tasks. The WMI is composed of subtests that assess auditory working memory, visual working memory, and working memory span. For example, a typical WMI subtest involves listening to a series of numbers and then repeating them in reverse order.
