Which term describes the IQ score increase across generations likely due to nutrition and education?

• A. Flynn Effect
• B. Stereotype Threat
• C. Achievement Test
• D. Aptitude Test

Answer: (A)

The Flynn Effect describes IQ score increases across generations, driven by environmental improvements such as better nutrition, more education, and broader cognitive stimulation. This trend shows up as higher average IQ scores over decades and is not about genetics changing quickly, but about the environments people grow up in amplifying test performance.

Stereotype Threat is about the anxiety that people may underperform because they fear confirming negative stereotypes about their group, which can affect test results in the moment but doesn’t explain long-term, generational shifts. An Achievement Test measures knowledge or skills someone has already learned, not changes across generations. An Aptitude Test aims to predict potential for future learning or performance, rather than documenting a historical rise in IQ scores.
