Which tool is designed for very young children and includes domains such as Verbal and Performance depending on edition, with measures of Working Memory and Processing Speed?

• A. Wechsler Intelligence Scale for Children (WISC)
• B. Bayley Scales of Infant and Toddler Development
• C. Preschool Language Scale, Fifth Edition (PLS-5)
• D. Wechsler Preschool and Primary Scale of Intelligence (WPPSI)

Answer: (D)

This tool is designed for very young children and a cognitive profile that includes Verbal and Performance domains, with measures of Working Memory and Processing Speed, best fits the preschool-age range. The Wechsler Preschool and Primary Scale of Intelligence is specifically developed for young children, roughly ages 2.5 to 7 years, and its editions structure cognitive abilities into Verbal and Performance components (with newer editions also providing separate indices for Working Memory and Processing Speed). This combination captures both language-based skills and nonverbal reasoning while also assessing memory and speed of processing, which are key for understanding early cognitive development. In contrast, the Bayley scales target infancy and toddler development; the PLS-5 centers on language abilities; and the WISC targets older children, not the very young group.
