What is the focus of the WMI component in the WISC-V?

The WMI, or Working Memory Index, is specifically designed to measure an individual's ability to hold and manipulate information in their mind for brief periods. This component of the WISC-V assesses how well a child can use information immediately after hearing or seeing it. Working memory is crucial for learning and reasoning, as it allows individuals to carry out tasks that involve remembering sequences, following instructions, and solving problems step by step.

In contrast, the other components focus on different cognitive abilities: Verbal Comprehension evaluates understanding and using language, Visual-Spatial Skills assess the ability to visualize and manipulate objects in space, and Processing Speed measures the speed at which one can process simple or familiar information. Each component contributes uniquely to understanding a child's overall cognitive functioning, but the WMI's emphasis on working memory makes it specific to the ability to hold and manipulate information in real-time.
