Reification occurs when a construct, such as intelligence, is treated as if it were a concrete, tangible object.
37
What was Francis Galton's contribution to intelligence testing?

39
The Stanford-Binet Intelligence Scale was developed by \_\_\_\_\_\_\_\_\_\_.
Lewis Terman
40
How does the Stanford-Binet Intelligence Scale measure someone's intelligent quotient (IQ)?
IQ = MA/CA \* 100 ## Footnote MA = mental age CA = chronological age

1. knowledge 2. fluid reasoning 3. working memory 4. visual-spatial processing 5. quantitative reasoning
42
What are the three types of Wechsler intelligence scales?
1. Wechsler Preschool and Primary Scale of Intelligence (W.P.P.S.I.) 2. Wechsler Intelligence Scale for Children (W.I.S.C.) 3. Wechsler Adult Intelligence Scale (W.A.I.S.)
43
What are the two types of scores on the Wechsler intelligence scales?
1. verbal score (vocabulary, comprehension, arithmetic) 2. performance score (picture arrangement, object assembly, block design)
44
How do the Wechsler scales determine intelligent quotients (IQ)?
* intelligence has a bell curve distribution * how spread out the scores are from mean of 100
45
What are the most prominant IQ levels on the Wechsler scale?
* under 70 = cognitively disabled * 80-115 = normal * above 130 = gifted About 68% of the population falls in the normal range.
46
When are the Wechsler intelligence scales more appropriate to use than the Stanford-Binet?
* Wechsler scales are key in identifying extreme levels of intelligence, including mental retardation and giftedness * The difference between Wechsler's verbal and performance scores is helpful in identifying learning disabilities
47
An appropriate synonym for "mentally retarded" is \_\_\_\_\_\_\_\_\_\_.
cognitively disabled
48
What are the four levels of mental retardation based on IQ scores?
* under 20 = Profound * 20-34 = Severe * 35-49 = Moderate * 50-70 = Mild About 85% of cognitively disabled individuals are considered mild.
49
Explain the differences between mild, moderate, severe, and profound mental retardation.
* **mild**: self-care, 6th grade education, hold job, live independently, social skills * **moderate**: self-care, 2nd grade education, menial job, function in group home * **severe**: limited language, requires care, no social skills * **profound**: requires complete care
50

normalization
51
# Define: factor analysis
statistical procedure that identifies common factors within a group of items by determining which variables are most correlated
52
How did Charles Spearman contribute to intelligence research?
* tested a wide variety of mental tasks on a large number of people * identified underlying variables *g* and *s*
53
What are Spearman's *g* and *s* variables?
* g* = general factor underlying all intelligence * s* = less important specialized abilities
54

57
# Define: crystallized intelligence
learned knowledge and skills that increase with age, such as vocabulary
58
# Define: savant
an individual, considered mentally retarded, who is exceptionally skilled in a specific area, usually math, art, or music
59

Howard Gardner
60

nurture; nature
68
What are examples of evidence supporting the idea that intelligence is hereditary?
* mental retardation from genetic defects (Down syndrome) * twin studies (identical twins have higher correlation between IQs than fraternal twins) * IQ scores of adoptees are more similar to biological parents than adopted parents
69
What are examples of evidence supporting the idea that intelligence is learned?
* mental retardation from prenatal exposure to alcohol (Fetal alcohol syndrome) * cultural-familial retardation (from sociocultural deprivation) * school attendance increases IQ scores * **Flynn effect** (increase in IQ scores over time due to better health care and schooling)
70
Define heritability as it relates to testing.
proportion of variation among individuals in a population resulting from genetic causes
71
How does the reaction range model explain intelligence using both nature and nurture influences?
This model states that genetic makeup determines the limits for a person's IQ. The upper limit can be reached when in an ideal environment, just as the lower limit can be displayed when in an impoverished environment.
