Intelligence
The global capacity of a person to act purposefully, think rationally, and deal effectively with their environment.
Mental Age
The average mental ability displayed by people of a given age.
Intelligence Quotient (IQ)
A measurement derived by dividing an individual’s mental by their chronological age, then multiplying by 100.
Intellectual Extremes
Low End - Intellectual Disability
High End - Giftedness
Stanford-Binet Test
A test developed by Lewis Terman who revised binet’s scale and adapted questions to American students.
Who invented the original IQ test and why?
Alfred Binet and Theodore Simon, for measuring children’s intellectual skills for early 20th century French schools.
Wechsler Adult Intelligence Scale
An intelligence test developed by David Wechsler in the 1930s with subtests grouped by aptitude rather than age level.
Main Areas of the WAIS
- Verbal Comprehension
- Perceptual Reasoning
- Working Memory
- Cognitive Processing Speed
Steps for developing Intelligence tests
- Developing Test Items
- Evaluating the Test Items
- Standardizing the Test
- Establishing Norms
Developing Test Items
Start with a large pool of potential test items.
Evaluating the Test Items
Separate effective test items from those that are ineffective or misleading.
Standardizing the Test
Ensuring consistent administration across all samples and populations to obtain accurate data.
Establishing Norms
Should be a bell-shaped curve when represented on a graph.
Reliability
The dependable consistency of a test over time, or the consistency in responses among similar items on the same assessment.
Test-retest reliability
Method for evaluating test reliability by giving a subject the same test more than once.
Alternate-forms reliability
Method of assessing test reliability in which subject take two different forms of a test that are very similar in content and level of difficulty.
Validity
The ability of a test to measure accurately what it is supposed to measure.
Criterion-related validity
Comparing people’s test scores with their scores on other measures already known to be good indicators of the skill or trait being assessed.
Concurrent validity
Comparing test performance to other criteria that are currently available.
Predictive validity
Deterimining the accuracy with which tests predict performance in some future situation.
Aptitude Tests
Tests designed to predict an individual’s ability to learn new information or skills.
Achievement Tests
Tests designed to measure an individual’s learning (not the ability to learn new information).
Spearman’s Two-Factor Theory of Intelligence
G-factor (General Intelligence) and S-factor (Specific Abilities)
R. Cattell’s Theory of Intelligence
G-factor was split into Fluid intelligence (ability to solve problems without past experience) and Crystallized intelligence (ability to acquire and apply knowledge)
L.L. Thurstone’s Theory of Intelligence
There are seven attributes that make up intelligence: Verbal comprehension, Numerical ability, Spatial relations, Perceptual speed, Word fluency, Memory, Inductive reasoning
J.P. Guilford’s Structure of Intellect Theory
Intelligence is comprised of 5 kinds of mental operations, 5 kinds of contents, and 6 kinds of products. 150 kinds of intelligence in total.
Steinberg’s Theory of Intelligence
People go through six steps when solving intelligence test problems: Encoding, Inferring, Mapping, Application, Justification, Response
