What is WAIS?
The Wechsler Adult Intelligence Scale (WAIS) is a psychological test designed to measure intelligence in adults and older adolescents.
It was developed by psychologist David Wechsler, who believed intelligence is not a single ability but a combination of multiple cognitive skills.

Clinical psychology
Neuropsychological assessment
Educational evaluation
Cognitive research
The modern version of the test is known as WAIS-IV.

Cognitive strengths and weaknesses
Memory performance
Problem-solving ability

Brain injuries
Dementia and cognitive declineGiftedness or high intelligence
Structure of the WAIS Test
The WAIS is divided into several subtests, grouped into four main index areas:
1. Verbal Comprehension Index (VCI)
This measures verbal reasoning and understanding of language.
It includes tasks like:
Defining words
Explaining similarities between concepts
Answering general knowledge questions
This section shows how well a person understands and uses language.
2. Perceptual Reasoning Index (PRI)
This section evaluates non-verbal and visual-spatial reasoning skills.
It includes:
Solving puzzles
Interpreting visual patterns
Working with shapes and designs
It measures how well someone can solve problems without language.
3. Working Memory Index (WMI)
This measures how well a person can hold and manipulate information in their mind.
Tasks may include:
Remembering number sequences
Mental arithmetic
Following multi-step instructions
Strong working memory is important for learning and decision-making.
4. Processing Speed Index (PSI)
This evaluates how quickly a person can process simple information.
It includes:
Symbol matching
Timed visual tasks
Quick decision-making exercises
It reflects mental speed and efficiency.
How WAIS Scoring Works
The WAIS produces a score called the IQ score (Intelligence Quotient).
Score Breakdown:
90–109 → Average intelligence
110–119 → High average
120–129 → Superior
130+ → Very superior (gifted range)
Below 70 → Possible intellectual disability range
The average IQ score is set at 100.
The test also provides:
Subscale scores
Index scores
Full Scale IQ (FSIQ)

The WAIS is designed for individuals aged:
16 years and older
It is commonly administered to:
Students (for learning assessment)
Patients in mental health clinics
Individuals with suspected brain injury
People undergoing cognitive evaluation for legal or occupational reasons

Raven’s Progressive Matrices
- Non-verbal IQ test
- Focuses mainly on pattern recognition
WAIS is considered more comprehensive because it measures multiple cognitive domains.
