The Wechsler Adult Intelligence Scale is a widely used intelligence test that assesses cognitive abilities in adults.
These index scores include:
- Verbal Comprehension Index (VCI): Assesses verbal reasoning, understanding of verbal concepts, and verbal knowledge.
- Perceptual Reasoning Index (PRI): Measures non-verbal reasoning, spatial processing, and visual-motor integration.
- Working Memory Index (WMI): Evaluates attention, concentration, mental manipulation of information, and working memory capacity.
- Processing Speed Index (PSI): Measures speed and accuracy in completing simple visual-motor tasks.
In other words, if a person performs well in one cognitive domain, they are likely to perform well in other related domains. Similarly, if there is an area of cognitive weakness, it should be reflected across related domains.
A comprehensive and individualized interpretation is crucial to making informed decisions about interventions or support if necessary.
