Which of the following would be highly generalizable?

• A. Preferred Music Genre
• B. Careers
• C. Working Memory Span
• D. Nutritional Needs

Answer: (C)

Generalizability depends on whether a measure taps a broad, domain-general construct that operates across tasks and populations. Working memory span reflects a domain-general cognitive resource used to hold and manipulate information across a wide range of tasks. Because this capacity underlies many cognitive activities, performance on memory-span measures tends to relate to diverse outcomes and holds across different groups and settings, making findings from such measures widely applicable. In contrast, preferences for a music genre, career choices, and nutritional needs are more tightly shaped by culture, environment, and life circumstances, so they don’t transfer as broadly across contexts.
