Exam 3 Flashcards
examines the elemental structure of a test through an evaluation of its correlate and underlying dimensions
psychometric approach to intelligence
examines the processes that underlie how we learn and solve problems
information-processing approach to intelligence
focuses on how humans adapt to real world demands
cognitive approach to intelligence
Binet’s Principles of Test Construction
Age differentiation and general mental ability
Binet’s definition of intelligence
- to find and maintain a definite direction or purpose
- to make necessary adaptations to achieve that purpose
- to engage in self-criticism so that necessary adjustments in strategy can be made
the simple fact that one can differentiate older children from younger children by the former’s greater capabilities
age differentiation
the total product of the various separate and distinct elements of intelligence
general mental ability
Spearman’s theory of intelligence
intelligence consists of one general factor plus a large number of specific factors
based on the well-documented phenomenon that when a set of diverse ability tests are administered to large unbiased samples of the population, almost all of the correlations are positive
psychometric g (positive manifold)
a method for reducing a set of variables or scores to a smaller number of hypothetical variables called factors - one can determine how much variance a set of tests or scores have in common
factor analysis
theory that there are two basic types of intelligence: fluid and crystallized
gf-gf theory
those abilities that allow us to reason, think, and acquire new knowledge
fluid intelligence
represents the knowledge and understanding that we have acquired
crystallized intelligence
Binet-Simon’s three levels of intellectual deficiency
Idiot-most severe
imbecile-moderate
moron-mildest
Downfall’s of the 1905 Binet-Simon scales
- lacked adequate measuring unit to express results
- lacked validity
- norms were based on far too small a sample
items are grouped according to age level
age scale
1908 Binet-Simon Scale
- improvement
- age scale format
- mental age
1916 Stanford-Binet
- larger sample
- not representative
- IQ
used a subject’s mental age in conjunction with his or her chronological age to obtain a ratio score, reflecting the subject’s rate of mental development
intelligence quotient (IQ)
1973 scale
- extended down the 2-year old level and up to 22 years
- added some tests beyond verbal skills
- standardization sample improved
- ALTERNATE FORMS
1973 scale issues
- reliability was not stable
- variability off
1960 Stanford-Binet
-deviation IQ
16 point deviation from a mean of 100 (how many deviations above/below the mean)
deviation IQ
Modern Binet Scale
-three group factors
three group factors
fluid
crystal
short term memory
1986 revision
- age scale eliminated - bad
- organized by content
- hierarchical model
2003 5th addition
- age scale and point scale
- equal verbal and nonverbal
- mixture of tasks - maintains interest
- start point
- 15 point SD
- 2-85+ age
contains similar content of increasing difficulty
point scale
