Definition

A performance-based task to assess spatial judgment and visualization skills.

Purpose

This measure tests a respondent’s total range of function with respect to spatial reasoning. It is therefore more specific and sensitive than a measure of global mental status and can be used to assess major problems in spatial reasoning (e.g., due to head trauma or Alzheimer’s disease) as well as minor variations that may be a consequence of normal development and aging.

Selection Rationale

Block Design was selected because it is a widely used, validated protocol that requires less time to administer than similar instruments.
