A widely used set of intelligence tests for adults and children that assess both verbal and nonverbal performance abilities is known as what?

• A. Gardner's Multiple Intelligences
• B. Emotional Intelligence
• C. Stanford-Binet Intelligence Scale
• D. Wechsler Scales

Answer: (D)

The Wechsler Scales. These batteries are designed to measure both verbal abilities and nonverbal (performance) abilities and are widely used for people of all ages. They come in versions for adults (WAIS) and children (WISC), with separate verbal and performance subtests that feed into a Full Scale IQ as well as index scores such as Verbal Comprehension, Perceptual/Performance Reasoning, Working Memory, and Processing Speed. This structure lets clinicians see how someone handles language-based tasks versus visual-spatial and reasoning tasks, highlighting strengths and weaknesses across age groups.

Gardner's theory presents multiple intelligences rather than a standardized battery. Emotional intelligence focuses on social and emotional skills, not a general IQ test. The Stanford-Binet is a well-known intelligence test too, but the Wechsler Scales are specifically designed to compare verbal and nonverbal performance across both adults and children in a widely used, practical framework.
