What does Spatial Span on the WNV measure?

Spatial Span on the Wechsler Nonverbal Scale of Ability (WNV) measures an individual's visual and spatial working memory. It assesses the ability to remember and reproduce a sequence of spatial locations or patterns, which reflects cognitive processes related to attention, memory, and visual-spatial reasoning. This task is particularly useful for evaluating nonverbal cognitive abilities in individuals who may have language barriers or communication difficulties.
