Intelligence test

In case of a real need (such as clues about attention problems, difficulty in learning processes, neuropsychological evaluation if there is a different situation compared to the average age), there are intelligence tests that provide very important data to experts. Today, the most important of these is the Weschsler Intelligence Scale for Children – IV (Wisc-IV Intelligence Test). Since the old intelligence test version WISC-R belongs to the 1980 norms, its application is not accepted today, its results are invalid and its application is unethical ( When the WISC-R test is applied, the performance of the child is determined to be higher than it is, and many children with normal levels labeled ‘superior’).It is important that applicants pay attention to this information as we know it is still being applied.

WISC-IV Intelligence Test

The WISC-IV (WISC-4) Intelligence Test, whose validity and reliability is accepted today, is an individually administered clinical measurement tool that measures the cognitive abilities of children between the ages of 6 years 0 months and 16 years 11 months (Wisc- IV, Pearson).

10 basic subtests are used in the WISC-IV evaluation. When necessary, 5 backup subtests are used. The 10 basic subtests used are grouped under 4 main headings. Each title aims to measure a separate mental skill. In summary, under 4 main headings; There are grouped tests to measure verbal comprehension, perceptual reasoning, working memory and processing speed.

Verbal Comprehension subtests in the group; It aims to measure verbal reasoning, verbal comprehension, concept formation, verbal knowledge and verbal expression ability. It measures their ability to understand the auditory stimulus, access verbally encoded information in long-term memory, and verbalize responses. Evaluates language and cultural proficiency and academic success.

Perceptual Reasoning subtests in the group; measures perceptual reasoning and perceptual organization. Visual perception and organization measures reasoning abilities using visually presented non-verbal material. In some subtests, visual motor coordination (hand-eye coordination) and speed, visuospatial and fluent reasoning are evaluated. It reflects cultural experience and school knowledge less than verbal comprehension. In summary, it evaluates non-verbal, visual reasoning functions.

Working Memory tests in the group; It measures short-term auditory memory, auditory attention, concentration, working memory. Skills in this group are associated with learning processes.

Processing Speed tests in the group; mental processing speed measures letter-motor processing speed. It measures visual perception and organization, visual scanning, competent control and maintenance of attention, skills under time pressure. Skills in this group are linked to attention skills.

WISC-IV Test; In summary, it is applied in order to recognize the mental skills of the child, to understand the intelligence status, to see which skills are strong and in which skills they need to be supported. Children’s learning difficulties, attention deficit and hyperactivity disorder, school adjustment problems, lesson failure, perception, friendship-communication problems, social anxiety, school phobia, etc. It shows whether many psychological symptoms such as intelligence level are related to the level of intelligence. Treatment and therapy processes are planned in a healthy way according to the test results applied when necessary.

Test Period

The application of the entire test takes approximately 1-1.5 hours. However, the test duration may differ depending on the working speed and motivation level of each child. Therefore, it can sometimes take up to 2 hours. A repeat (re-application) of the WISC-IV test can be re-administered at least 1 year after the first administration. It is not recommended to apply more than once in the same year.

WISC-IV Report

Reporting is usually reserved for experts and family. It is not recommended to give information containing scores to the family in order not to label the child. For this reason, the family is informed that includes verbal information and suggestions that do not include the scores of the result. When the referral for the intelligence test is made by another specialist (the child’s doctor, teacher, etc.), the evaluation report resulting from the test is delivered to the specialist with the knowledge and approval of the family.
