conclude that the tests or subtests (at least partly) measure the same factor. A factor
analysis determines which sets of tests form groups.
-Factor analysis provides clues about the nature of intelligence, but it cannot provide a
theory of intelligence. The names given to the factors are up to the investigator and
therefore include a degree of subjective judgment.
-Factor analysis can never be more meaningful than the individual tests on which it is
performed. To identify the relevant factors in human intelligence, one must include an
extensive variety of tests in the factor analysis, and be assured there are many.
-Many factor analyses have been performed on tests of intellectual abilities, such as
Thurstone’s seven factors, Cattel’s fluid intelligence(gf) and crystallized intelligence(gc)
-Word analogies and vocabulary, general information, and use of language tests load
heavily on the crystallized intelligence factor.
-According to Cattel, gc depends on gf. Fluid intelligence supplies the native
ability(potential ability to learn and solve problems), whereas experience with language
and exposure to books, school, and other learning opportunities develop crystallized
An Information Processing Theory of Intelligence
-According to Robert Sternberg, the degree of success that people achieve in life is
strongly affected by the extent to which they effectively analyze and manage their
unique combinations of strengths and weaknesses.
-Sternberg has devised a triarchic theory of intelligence that derives from the information
processing approach used by many cognitive psychologists. The three parts of the
theory deal with three aspects of intelligence: analytic intelligence, creative intelligence,
and practical intelligence.
-These three aspects contribute to successful intelligence, which is the ability to (a)
analyze one’s strengths and weaknesses,(b) use the strengths to greatest advantage,
and (c) minimize the impact of weaknesses by overcoming or compensating for them.
-Analytic intelligence, consists of the mental mechanisms people use to plan and
-The following three components of analytic intelligence serve three functions:
