Which category includes both verbal and nonverbal domains, such as verbal communication and math reasoning?

• A. Developmental Delay
• B. Cognitive Delay
• C. Specific Learning Disability
• D. Speech Impaired

Answer: (B)

Verbal and nonverbal domains are tied together by underlying thinking and reasoning skills. When there is a cognitive delay, the challenge is in overall intellectual functioning—how a person reasons, solves problems, and processes information—which affects both language-based tasks (verbal communication) and nonverbal tasks like math reasoning. This makes cognitive delay the best fit because it encompasses difficulties across a range of thinking abilities, not just a single skill.

Developmental delay is broader and covers multiple developmental areas, but the question emphasizes the thinking processes behind both verbal and nonverbal tasks. A specific learning disability, by contrast, involves difficulties in particular academic skills (like reading or math) despite typical overall intelligence, so it doesn’t inherently describe verbal and nonverbal cognitive functioning together. A speech impairment focuses on speech production or language use itself, not on broader cognitive reasoning across domains.
