The Symbol Search subtest is designed to
assess information processing speed and visual perception
. It is one of three subtests that contribute to the Processing Speed Indices derived from the Wechsler intelligence scales.
What is symbol search on WISC V?
“In addition to processing speed, the subtest measures
short-term visual memory
, procedural and incidental learning ability, psychomotor speed, visual perception, visual-motor coordination, visual scanning ability, cognitive flexibility, attention, concentration, and motivation.
What do the WAIS subtests measure?
The subtest was developed to measure
non-verbal reasoning and the ability to understand abstract visual information
. The individual is presented with a picture of a pair of scales in which there are missing weights, and they have to choose the correct weights to keep the scales in balance.
What does Coding subtest measure?
Coding measures
visual-motor dexterity, associative nonverbal learning, and nonverbal short-term memory
. Fine-motor dexterity, speed, accuracy and ability to manipulate a pencil contribute to task success; perceptual organization is also important. Coding is a timed core Processing Speed subtest.
What is the difference between coding and symbol search?
Coding, which requires children to draw symbols, is heavily influenced by
grapho-motor demands
. Children with poor handwriting or dysgraphia may struggle with this task. Symbol Search has less emphasis on motor output but requires rapid differentiation of abstract symbols.
What is a set error on Symbol search?
Some items contain a symbol in the search group that shares
similar characteristics
with the target symbol (i.e., a set error symbol). On the items for Naming Speed Literacy and Naming Speed Quantity, each misnamed attribute is considered an error.
How do I read my WISC scores?
| Composite Score Range Traditional Description WISC-V Classification | 110 – 119 High Average High Average | 90 – 109 Average Average | 80-89 Low Average Low Average | 70 – 79 Borderline Very Low |
|---|
What types of skills do the Wechsler subtests measure?
The Wechsler Scales provide an estimate of global intellectual ability (Full Scale IQ) and four Composites: Verbal Comprehension Index (VCI), which measures the
application of verbal skills and information to problem solving
; Perceptual Reasoning Index (PRI), which measures the ability to engage in nonverbal reasoning …
How is your IQ calculated?
The equation used to calculate a person’s IQ score is
Mental Age / Chronological Age x 100
. On most modern IQ tests, the average score will be 100 and the standard deviation of scores will be 15.
What is the highest IQ score on Wechsler?
The highest score that can be obtained on the Wechsler Intelligence Scale for Children-III, which is the preeminent test of intelligence used in the United States today for identifying gifted children, is
160
. For the Wechsler Adult Intelligence Scale-III, the ceiling is slightly lower: 155.
What is coding on IQ test?
Coding—the student matches and copies symbols that are associated with either objects (i.e., Coding A) or numbers (Coding B). This subtest is a
measure of processing speed
, short-term visual memory, mental flexibility, attention, and motivation. … This subtest measures the student’s general fund of knowledge.
What is Wechsler IQ test?
The Wechsler Adult Intelligence Scale (WAIS) is
an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents
. The original WAIS (Form I) was published in February 1955 by David Wechsler, as a revision of the Wechsler–Bellevue Intelligence Scale, released in 1939.
What does the WISC measure?
The WISC-IV measures
intellectual ability of children from 6 to 16 years
. It was developed to provide an overall measure of general cognitive ability, and also measures of intellectual functioning in Verbal Comprehension (VC), Perceptual Reasoning (PR), Working Memory (WM) and Processing Speed (PS).
What is a relative weakness?
When a scaled or standard score is compared with another scaled or standard score, the phrases ‘relative strength’ and ‘relative weakness’ are used
to describe statistically significant differences when comparing performance on one score in relation to another
.
What is a good Wisc score?
| Standard Scores Qualitative Descriptions Percent of Cases | 120 – 129 Very High 6.7 % | 110 – 119 High Average 16.1 % | 90 – 109 Average 50 % | 80 – 89 Low Average 16.1 % |

Can anxiety affect processing speed?
When any of us feel anxious, we freeze for a moment. During that time,
we’re not processing information as fast as
we might otherwise be. We may take longer to respond, make decisions, or size up situations. That’s how anxiety can impact processing speed.
