Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III)
The Wechsler Preschool and Primary Scale of Intelligence – Third Edition (WPPSI-III Australian) is similar to the WISC and is used to assess young (usually preschool children, Ages 2:6 to 7:3 years.).
The Whip-See is not a stock man’s whip or a blender! It is simply an abbreviation that many psychologists use to represent the Wechsler Preschool and Primary Scale of Intelligence. Like the WISC is not the WISK! (Sorry for the confusion – check out the WISC-IV here).
The WPPSI is not a Whip-See or a Whip!
What is a WPPSI?
The WPPSI is a colorful, current, and interesting for children. It measures Full Scale IQ, Verbal IQ, Performance IQ, and Processing Speed and has an optional General Language Composite. IQ stands for Intelligent Quotient. It is an indication of a person’s intelligence as indicated by an intelligence test.
The WPPSI had three main Scales:
- Full Scale IQ (FSIQ) – most reliable and representative of general intellectual functioning. (Information, Vocabulary, Word Reasoning)
- Verbal IQ (VIQ) – acquired knowledge, verbal reasoning and comprehension, and attention to verbal stimuli.
- Performance IQ (PIQ) – fluid reasoning, spatial processing, attentiveness to detail, and visual-motor integration. (Block Design, Matrix Reasoning, Picture Concepts)
Verbal IQ Sub Tests
- Information: recall of facts learned through interaction with the world.
- Vocabulary: knowledge of and the ability to express the meaning of words.
- Word Reasoning: measures verbal comprehension and reasoning.
Performance IQ Sub Tests
- Block Design: measures the analysis and reproduction of abstract design with blocks.
- Matrix Reasoning: measures verbal reasoning, verbal comprehension, general reasoning ability, the ability to integrate and synthesise different types of information, verbal abstraction, domain knowledge and the ability to generate alternative concepts.
- Picture Concepts: measures abstract, categorical reasoning ability.
