Chapter 10 Flashcards
How did the Stanford- Binet (Terman) measure intelligence?
- IQ (radio intelligence quotient)
- IQ= mental age / chronological age x 100
Spearman’s two factory theory of intelligence proposed two ideas of intelligence- what are they?
- General intelligence (g) : part of all forms of intellect
2. Specific intelligence (s): special abilities
Factor analysis was used in who’s theory?
- Spearman
Verbal comprehension, verbal fluency, memory, and perceptual speed were some of the 7 primary abilities proposed by _____
Thurstone
The hierarchical model of intelligence is a compromise between __ and ___
- g and s
The Binet- Simin scale gave a measure of ______ age
- Mental
This scale includes :
Verbal Comprehension, Perceptual Reasoning,
Working Memory,
and Processing Speed.
It is the most widely used intelligence test
- Weschler scale
Using factor analysis, there appear to be 2 major “factors” measures on the WAIS- what are they?
Verbal abilities and performance abilities (nonverbal subtests)
This approach to intelligence focuses on the use of standardized tests to identify individual differences among ppl.
- Psychometric approach
IQ tests girls ordered differences among ppl. What does that mean?
- It results in an evaluative dimension in which person A is less or more intelligent than person B
What does it mean to say that IQ tests are pragmatically oriented?
- They determine the type of education that a student should receive
IQ scores correlate ___ to ____ with school performance
0.5 to 0.6
What is the difference between reliability and validity?
- Reliability = asks whether the test gives repeatable scores (consistency of measurement)
- Validity = asks whether the test measures the intended domain
- -> criterion validity determines whether Iq can predict a criterion such as school performance
Do IQ tests work?
- Reliable? In the short term, yes. Long term, less so.
- Valid? Yes, they are reasonable predictors of success in school and the workplace, particularly for more complex jobs
Dynamic testing can improve ______
- Validity
