Full Scale Intelligence Quotient (FSIQ)
Full-Scale Intelligence Quotient (FSIQ) is a term coined for an individual’s complete cognitive capacity. With regard to children, the Wechsler Intelligence Scale for Children (WISC) is the most commonly used test in helping measure a child’s mental capacity. Children with autism spectrum disorder (ASD or autism), more often than not, require special education to help them improve and develop skills despite their developmental disability.
David Wechsler originally developed WISC in 1949. In 2003, the fourth and latest edition of WISC was published and is presently being used by practitioners to determine the intellectual strengths and weaknesses of children ages 6–16. The WISC-IV consists of four different indexes, each with its own subtests, named as follows:
Verbal Comprehension Index (VCI)
- Similarities – Here your child is asked what likeness two different words have.
- Vocabulary – Your child is usually given 35 words to define.
- Comprehension – Here your child is asked 16 questions that pertain to social situations.
- Information – This is usually a 29-question subtest about general knowledge.
- Word Reasoning – Here your child is given a word related to a specific object or a word that your child needs to be able to say.
Perceptual Reasoning Index (PRI)
- Block design – This is a timed test with your child copying a presented model with the use of blocks.
- Picture concepts – Your child is asked to identify pictures that go together in a series of pictures laid out in rows.
- Matrix reasoning – Here your child is presented with a series of pictures and will be asked to fill in the missing detail.
- Picture completion – Your child points or names a missing part of a picture that is presented to him.
Working Memory Index (WMI)
- Digit span – Here your child is given a series of numbers and is asked to repeat it either in sequence or in reverse order.
- Letter-number sequencing – Here your child is given a set of numbers and letters. The examiner will then ask for a prearranged order.
- Arithmetic – This is a timed oral questioning of arithmetic questions.
- Processing Speed Index (PSI)
- Coding – This is a timed subtest wherein children are asked to write a digit-symbol code.
- Symbol search – Here, a row of symbols and a “target” symbol are presented to your child. Your child is then asked if the target symbol is present in each row.
- Cancellation – Here your child is presented with random pictures
