artificial intelligence
a
construct validity
the extent to which evidence shows that a test measures a particular hypothetical construct
content validity
refers to the degree to which the content of a test is representative of the domain it’s supposed to cover.
correlational coefficient
a numerical index of the degree of relationship between two variables
criterion validity
is estimated by correlating subjects’ scores on a test with their scores on an independent criterion of the trait assessed by the test
crystallized intelligence
learned knowledge and skills such as vocabulary that tend to increase with age
Downs Sydndrome
Extra 21st Chromosone
equivalent form reliability
the consistency of measurement based on the correlation between scores on two similar forms of the same test taken by the same subject.
fluid intelligence
those cognitive abilities requiring speed or rapid learning that tend to diminish with adult aging
G-factor
general intelligence across all academic domains
giftedness
1-2% of population. IQ of 135+
hydrocephaly
“water on the brain”
intelligence quotient (IQ)
a child’s mental age divided by chronological age, multiplied by 100
mental age
indicates that he or she displayed the mental ability typical of a child of that chronological age
mental retardation
refers to subaverage general mental ability accompanied by deficiencies in adaptive skills, originating before age 18.
multiple intelligence
Gardner developed a theory that features eight different kinds of intelligence including musical, interpersonal, spatial-visual and linguistic intelligences.
phenylketonuria
rare condition in which a baby is born without the ability to properly break down an amino acid called phenylalanine.
reliability
A statistical measure of a tests consistency, or ability to result in similar scores if given repeatedly.
savant syndrome
excel in one particular subject, but slow in everything else.
split-half reliability
The correlation coefficient determined by comparing first half of the measurement to the second half. Measure of the internal consistency of a test or measuring device.
standardization
refers to the uniform procedures used in the administration and scoring of a test
t-score
A group of statistics used to determine if a significance difference exists between the means of two sets of data.
test-retest reliability
The correlation coefficient determined by comparing the scores of the same measuring device administered to the same people on two different occasions.
triarchic theory of intelligence
Three distinct types of intelligence” analytic, Creative, Practical.
