Question

Comparing the average performance of the initial WAIS standardization sample with the average performance of the most recent WAIS standardization sample provides convincing evidence of

a) Test-retest reliability
b) Cultural bias in intelligence testing
c) Flynn effect
d) Genetic determinants of intelligence changes over time

Answer 1

Comparing initial and recent WAIS standardization samples shows the Flynn effect, which is the rise in average IQ scores with each generation, suggesting environmental influences on these changes.

Step-by-step explanation:

Comparing the average performance of the initial WAIS standardization sample with the average performance of the most recent WAIS standardization sample provides convincing evidence of the Flynn effect. The Flynn effect refers to the observation that each generation has a significantly higher IQ than the previous one, which suggests that environmental factors such as education and nutrition are likely influencing these changes. However, this observation does not necessarily imply that individuals are intrinsically more intelligent but indicates a rise in test scores over time.
