Topic 1: Intelligence Evaluation Flashcards
Why is the study not generalizable?
The sample was only from the Netherlands, so the results lack population validity and can’t be generalized to other populations.
How reliable is the RPM test?
Test-retest reliability is high (0.8 for children, 0.9 for adults), meaning the test is consistent and replicable.
How is the RPM useful?
It shows that both genetic and environmental factors influence intelligence, which can be applied in various settings.
Why does the RPM lack validity?
The study lacks population validity, and the validity can be affected by the type of test used.
What ethical guidelines were followed in the study?
Informed consent was obtained, and participants were protected from harm. The test was valid for measuring fluid intelligence.
How does nature influence intelligence?
Intelligence development is influenced by innate biological factors, and genetic factors play a significant role in IQ variance.
How does nurture influence intelligence?
IQ can be influenced by a person’s background, and environmental factors (like the Flynn Effect) can affect IQ scores.
What is the freewill perspective on intelligence?
Environmental influences are within our control, and factors like assortative mating affect genetic transmission.
What is the determinism perspective on intelligence?
We cannot control natural or genetic influences; people do not have control over their genetics or family environment.
What does reductionism say about intelligence?
Reductionism uses the ‘g’ factor to explain intelligence and focuses on a small range of cognitive abilities.
What does holism say about intelligence?
Holism looks at multiple cognitive abilities (like Gardner’s theory) and considers a broader range of factors contributing to intelligence.
How does individual perspective view intelligence?
Individual performance remains stable across situations, as seen in the correlation of IQ scores in MZ twins.
How does the situational perspective view intelligence?
Situational factors like illness or stress can affect cognitive abilities, and IQ tests might include cultural knowledge.
Why is psychometric testing scientific?
It relies on standardized models, removes confounding variables, and is based on consistent measures of intelligence.
Why is psychometric testing considered unscientific by some?
There is no agreed definition of intelligence, making it difficult to measure in a truly scientific way.
What is the issue with IQ tests in relation to the Flynn Effect?
IQ tests like the RPM may not measure a single ‘g’ factor of intelligence. The Flynn Effect shows that IQ scores have increased over generations, suggesting environmental factors play a significant role.
How does the Flynn Effect challenge the idea that IQ tests measure a fixed intelligence?
The Flynn Effect shows that IQ scores have increased over time, likely due to improved education and problem-solving abilities, not just genetic factors.
