Final answer:
An optional subtest on the WPPSI is Animal Coding, which assesses a child's processing speed and attention to detail. The WPPSI is part of a suite of tests that yield a comprehensive IQ score and profiles of cognitive strengths and weaknesses.
Step-by-step explanation:
An optional subtest on the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is Animal Coding. This subtest evaluates a child's ability to match symbols with their corresponding shapes or animals. The WPPSI, like its counterparts, the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC), provides scores on various cognitive abilities, including Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed, leading to a Full Scale IQ score.
The WPPSI offers several optional subtests, which provide additional information about a child's cognitive abilities. For instance, the Animal Coding subtest is accessible for younger test-takers and provides evaluators with insight into their processing speed and attention to detail. Education professionals use these assessments to identify areas of strength and weakness in a child's cognitive development and to recommend appropriate educational strategies.
It's important to note that while optional subtests are available, not all children will need to complete them. Decisions on which subtests to administer can be based on the specific referral question for the assessment or particular areas of concern raised by parents or educators.
