Study Notes

Intelligence and Psychological Testing

Psychological testing is a standardized measure of a person's general ability or specific mental abilities.
Intelligence tests measure general ability.
Aptitude tests measure specific mental abilities.
Achievement tests measure mastery of knowledge.
Personality tests measure motives, interests, values, and attitudes.
Standardization refers to the uniform procedures used in administering and scoring a test.
Reliability refers to measurement consistency. Tests should provide similar results when administered to the same person multiple times.
Validity refers to whether a test accurately measures what it is designed to measure.
Content validity: test content reflects the domain being measured.
Criterion-related validity: measured performance is correlated with an independent/other measure.
Construct validity: the extent to which a test measures a theoretical construct.
Intelligence is a global capacity to think rationally and act purposely to deal effectively with the environment.
Modern views of intelligence consider cultural and social factors. Intelligence is not a concrete physical object but a hypothetical abstract construct.
Intelligence tests are based on a normal distribution, with most scores near the center and fewer toward the extremes. This is measured using standard deviations.

Evolution of Intelligence Testing

Sir Francis Galton (1869): Pioneer in studying heredity and intelligence, focusing on inherited traits.
Alfred Binet and Theodore Simon (1905): Created the first practical intelligence test to identify students needing assistance (Binet-Simon Intelligence Scale).
Lewis Terman (1916): Developed the Stanford-Binet Intelligence Scale, which introduced the concept of IQ (Intelligence Quotient) = (Mental Age/Chronological Age) x 100.
David Wechsler (1955): Developed the Wechsler Adult Intelligence Scale (WAIS) focusing on deviation IQ, which is less dependent on verbal abilities.

Key Concepts in Psychological Testing

Mental ability tests : assess general mental ability or potential, Aptitude- specific mental abilities, Achievement- prior learning.
Personality tests: assess individual motives, interests, attitudes.
Validity and reliability are essential for meaningful and accurate test results.
Standardization is necessary (same procedure).
Normal distribution is used to interpret results.

The Debate about the Structure of Intelligence

Charles Spearman: Proposed general mental ability ("g") and specific mental abilities ("s").
L. L. Thurstone: Criticized the focus on "g", proposing 7 primary mental abilities.

Broadening the Concept of Intelligence

Guilford's theory: proposed 150 distinct mental abilities.
Fluid vs. crystallized intelligence: fluid is problem-solving, crystallized is knowledge and skills.
Biological indexes: brain size and volume, correlation with childhood IQ and later health

Expanding the Concept of Intelligence

Sternberg's triarchic theory: proposes analytical, creative, and practical intelligences.
Gardner's theory of multiple intelligences: proposes 8 distinct intelligences (e.g., logical-mathematical, linguistic, musical).
Goleman's emotional intelligence: the ability to perceive and manage emotions in oneself and others.
Salovey's components of emotional intelligence: defining, expressing, understanding, rationally regulating emotions

Calculating the Intelligence Quotient (IQ)

Determining a person's IQ using mental age and chronological age in a formula.
Calculating IQ scores using mental and chronological ages.

Intelligence and Psychological Tests: Subtests

Information: General knowledge, facts.
Arithmetic: Basic arithmetic skills.
Similarities: Finding similarities between concepts.
Digit span: Repeating numbers forwards and backwards.
Vocabulary: Defining words.
Block design: Rotating/assessing visual-spatial relationships.

Basic Issues in Intelligence Testing

Intelligence tests rely on normal distributions and standard deviations for analysis.
Raw scores are typically converted to deviation IQ scores (mean 100, standard deviation 15).
Deviation IQ scores can be converted into percentile scores.

Reliability and Validity of IQ Tests

IQ tests are generally reliable, with correlations often above .90.
Issues remain with validity. They often measure academic ability but not necessarily practical or social intelligence.
Correlation with school success or years in school suggests some predictive value.
Issues remain about application and appropriateness in different cultures.

Extremes of Intelligence: Intellectual Disability and Giftedness

Intellectual disability is diagnosed based on IQ scores and adaptive skills deficit.
Giftedness is characterized by superior intellectual abilities that are 2 standard deviations above the mean. Also measured by IQ scores, but also involves creativity, leadership, etc.
Identification of giftedness and intellectual disability can be based on ideals vs. practical factors.
Research highlights stereotypes associated with these phenomena.
Environmental factors, such as socio-economic disadvantage, may contribute to differences.

Heredity and Environment as Determinants of Intelligence

The degree to which intelligence is determined by genetics vs. nurture is complex.
Heritability studies (e.g., comparing twins) indicate that both genetics and environment play a role.
The Flynn effect: IQ scores have increased over time.
Reaction range: genetic potential for intellect, environmental factors create the development.

Cultural Differences in IQ

Cultural factors may influence IQ scores, both due to differences in the way tests are built and cultural differences in educational, social, etc. experience.
Research flaws exist, like the cultural bias of IQ tests themselves.
Socioeconomic disadvantage may play a role in IQ disparities.
