1. The difference between fluid intelligence and crystallized intelligence has to do with
a. performance of verbal tasks versus performance of spatial tasks
b. amount learned versus amount learned and now forgotten
c. speed of learning versus amount already learned on some topic
d. recall memory versus recognition memory
2. Why do critics complain about questions on IQ tests that ask for factual information?
a. such questions do not predict performance in school
b. such items measure knowledge, not necessarily ability
c. factual knowledge is unrelated to problem-solving ability
d. these questions fail to differentiate among people who take the tests
Please post your answers and reasons for them, and we'll be happy to critique them.

Thank you. These 2 questions have been stumping me.
1. I chose answer B. because fluid intelligence is what you learn and crystallized is what you have learned and was through experience...
2. I chose answer A. because IQ tests were formed to reflect school performance...
Please help me! I think these are right. Are they?
I don't see how B can be the correct answer to # 1. Intelligence has nothing to do with knowledge that has been forgotten.
Fluid intelligence is often measured by the performance part of an IQ test while crystallized intelligence relates strongly with the verbal parts of the test. Fluid intelligence is also measured by how quickly a person can solve a new problem, regardless of previous knowledge.
Please check your text materials to see what the author emphasizes. Also check this site with a variety of explanations of these two different aspects of intelligence.
For # 2, the emphasis is upon IQ tests that ask for factual knowledge. For that reason, B seems like the best answer. Also -- IQ tests were first developed by the U.S. army during World War I to determine the abilities of incoming soldiers. They later were used in schools to predict academic achievement.
