Intelligence (language, thinking & intelligence) Flashcards
What is intelligence testing, who created it, when was it created and which test is the most popular in Weschler?
- Testing school children
- Binet-France
- In 1916 –> “Stanford-Binet”
- Adult test
How is a kid’s IQ calculated? What is the average?
- Mental age/chronological age x 100
- 100
How is a adult’s IQ calculated? What is the average?
- Deviation score - you vs others your age
- 100
Distribution of IQ follows what?
Normal (bell) curve
What does 2% of scores above IQ of 130 equal to?
“Superior”
What does 2% of scores below IQ of 70 equal to?
“Development disabilities”
What is the “Flynn effect” and what is the average rate?
It’s the IQ scores rising over time. The average weight is 3 IQ points increase per decade
What are the requirements for Good Tests and what are they? (3)
- Reliability : get similar scores for each other each time you take the test
- Validity : measures what it is intended to measure
- Standardization : administered the same way to everybody
What is the correlation for elementary school, high school, university and graduate school?
Correlation is positive, but declines:
- e.s. : 0,6-0,7
- h. s. : 0.5-0.6
- uni. : 0,4-0,5
- g. s. : 0,3-0,4
*intelligence alone isn’t sufficient enough for academic achievement
Most tests are written with what type of people in mind?
White middle-class children/adults
What do the studies show? What are the explanations? (2)
- Asian-Africans > Caucasian > Hispanic > African-American
- Genes (G) –> determine intelligence; Env. (E) –> how you are raised
What research was done on “Nature vs Nurture” ? (twins) (4)
- MZ twins raised together : IQ’s very similar = G
- DZ twins = less similar
- MZ twins raised apart : IQ scores highly similar = G
- Adoption studies : IQs are more similar to biological parents’ IQs vs adoptive parents
What are the factors of E? (3)
- Flynn effect –> unlikely due to G
- Schooling –> little school = poor IQ
- Early intervention –> large initial effects on IQ, then “fade-out” –> other long-term positive effect
What are the three main elements of “Nature vs Nurture” ?
- Research
- E factors
- Family size and birth order
What are the factors of family size and birth order?
- smaller families, children who are earlier born = higher IQ (small effect)
- preternal factors: alcohol, exposure to lead and prolonged malnutrition lowers IQ of fetus,
