WISC 4 Intelligence Test

The Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV), is an intelligence test designed to assess the cognitive abilities of children. Targeting individuals aged 6 to 16, WISC-IV measures performances across a broad cognitive spectrum. The test aims to understand cognitive processes, evaluate problem-solving abilities, and identify learning difficulties.

WISC-IV consists of four main sections:

1- Verbally Mediated Index (VMI): This section includes vocabulary, comprehension, and logical reasoning skills. The Verbally Mediated Index evaluates language skills by focusing on verbal abilities.

2- Perceptual Reasoning Index (PRI): This index assesses visual-spatial abilities and visual problem-solving skills. Tasks such as figure similarities, picture completion, and arrangement are part of evaluating visual object perception.

3- Working Memory Index (WMI): It evaluates a child's short-term memory and processing speed. Tasks like reading numbers backward, coding, and memory tests are components of this index.

4- Processing Speed Index (PSI): This index measures visual scanning and quick task performance. Tasks like visual-motor speed, symbol search, and picture matching are included in evaluating processing speed.

WISC-IV is used to understand children's cognitive profiles and identify learning difficulties. It is a frequently used tool in education and psychology to comprehend children's cognitive development and provide appropriate support for their individual needs.
