Question

Quizplus · Accepted Answer

The Flynn effect refers to the phenomenon of increasing average IQ scores over time. The magnitude of this effect is influenced by when the test was normed, as IQ tests are standardized based on the average performance of a certain population at a certain time. As the population or time of norming changes, so too can the average performance on the test, and thus the magnitude of the Flynn effect. The other factors may also play a role in the magnitude of the Flynn effect, but they are not as influential as the time of norming.
