A measure for nonverbal intelligence
Individuals comparison of verbal and non-verbal intelligence
Used to overcome biases in language, culture and educational background.
Provides clinician an opportunity to observe behavior in standard setting because performance test requires longer interval of sustained effort, concentration and attention than verbal tasks

- consists of subsets that requires verbal
- consists of subsets that require the
individual to respond by performing
such as pointing to a missing detail
Is the ability to define words
The most stable measure of intelligence
Individuals that show deterioration because of emotional or brain damage shows that the vocabulary subtests to be the last one affected.
Mild concentration difficulties that lower optimal performance do not affect vocabulary until they become severe.
Used to evaluate premorbid intelligence in some cases
Measures thedegree to which one has learned, been able to comprehend and verbally express vocabulary
Consists of 15 paired items of increasing difficulty
Easier items just need responses from previously learned associations i.e. ( How is bread and water alike?) while difficult items require abstract thinking as they are already dissimilar objects i.e. (how is an ant and rose alike?)
Character of persons thought processes is seenin many cases i.e. (schizophrenic giving idiosyncratic concepts)
Measures abstract verbal reasoning
Contains 15 relatively simple problems
Retaining figures in memory while manipulating it is the challenge
Sample of ninth most difficult question:
A person with $28 spends $.50, how much does he have left?
The main aspect measured is concentration, memory and reasoning
Requires the subject to repeat digits, given at the rate of one per second, forward and backward.
Measures short-term auditory memory

Measures attention, concentration and mental control
Measure subject range of knowledge
Factors that tends to influence the test scores are subjects curiosity and acquisition of knowledge, alertness to environment and alertness to cultural opportunities.
Asks three type of questions:

One of the newest of WAIS III subtest
Not required to obtain verbal IQ score
Made up of seven items in which subject is asked to reorder lists of numbers and letters.
It measures working memory and attention
Subject is shown a picture wherein some important detail is missing while timed
Visual discrimination is measured
Some factors that may affect the score are visual-perceptual difficulties or environmental awareness
Subjects are given 120seconds to copy numbers from 1-9 each paired with a symbol as much as they can
Measures visual-motor dexterity, degree of persistence, speed of performance and ability to learn an unfamiliar task
Age, inadequate visual acuity and motor capabilities may affect the results
Materials used are nine variously colored blocks and a booklet with specific geometric design or configuration
Subject must arrange the block in increasingly difficult designs
Measures nonverbal concept formation, abstract thinking and neurocognitive impairment
Enhances WAIS III assessment of fluid intelligence
Subject is presented with a nonverbal, figural stimuli and is tasked on finding a pattern or relationship between the stimuli
Measures abstract reasoning, information processing and fluid intelligence
Requires subjects to notice relevant details, cause and effect relationships.
The test consists of 11 items, which consists of related pictures similar to comic strips, the subject must arrange the pictures in the right order to tell a story
Measures nonverbal reasoning ability and interpretation of social situations
Consists of puzzles that the subject have to put together as quickly as possible
Measures visual assembly and its coordination with simple assembly skills
Subject is shown two geometric figures. The task is then to search from among a set of 5 additional search figures and determine whether the target appears in the search group. Ther
