What task component distinguishes between the wechsler scales from the SBIS?

The task component that distinguishes between the Wechsler scales and the SBIS (Stanford-Binet Intelligence Scales) is the format and structure of the tests.

The Wechsler scales, which include the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC), are individually administered tests that use a variety of tasks to measure different cognitive abilities. They typically include subtests that assess verbal comprehension, perceptual reasoning, working memory, and processing speed. The test-taker is presented with a series of tasks or questions and their responses are scored based on their accuracy and speed.

On the other hand, the SBIS is also an individually-administered intelligence test, but it follows a different format. The SBIS is a series of hierarchical subtests that progressively assess a person's cognitive abilities from early childhood to adulthood. The tasks in the SBIS include items such as pattern completion, vocabulary, quantitative reasoning, and working memory. The test-taker is presented with a variety of different tasks, and their responses are scored based on their correctness and the difficulty level of the tasks.

So, to answer your question, the task component that distinguishes between the Wechsler scales and the SBIS is the way in which the tasks are structured and administered within the tests. The Wechsler scales use a broader range of tasks to measure various cognitive abilities, while the SBIS follows a hierarchical subtest model to assess cognitive abilities.
