The Eleven Plus Exam
Cyril L. Burt
- Measuring intelligence
- Intelligence=inherited
- Help identify talented children, regardless of class or background, and guides them toward needed educational resources
Psychometric approach
French psychologist Alfred Binet in 20th century
- Distinguish mentally retarded children
- Which to place in remedial education
- cognitive skills closely linked to success in school and focuses on developing quantitative measures of intelligence through such means as intelligence tests
- Measures of vocabulary (Peabody)
- Nonverbal reasoning (Ravens Progressive Matrices)
- Spatial abilities (Leitter Performance Scales)
Intelligence quotient (IQ)
mental age times real chronological age
- Not used currently
- Intelligence increases as ages
Standford -Binet Intelligence Scales
*2 year old children to adults
Weshsier Intelligence Scale (WISC-IV)
Verbal comprehension index, perceptual reasoning index, processing speed index, working memory index
Verbal comprehension index (VCI)
comprehension of language-based materials and the ability to solve problems posed in words
Perceptual reasoning index (PRI)
Uses pictures and other visual materials; largely avoids using language
- Complete missing details in pictures
- Arrange pictures to form a reasonable sequence of events
- Use blocks to re-create abstrate designs
Processing speed index (PSI)
How quickly a child seems to process information in tasks ranging from time spent searching for a target shape among a much larger set of shapes to tasks identifying all instances of a target image
Working memory index (WMI)
Performance on tasks that draw on working memory
Bell curve/normal distribution curve
range and distribution of scores in the population
- Curve for intelligence test scores and how such scores would be ideally distributed in a large population
- most common score=highest point of the curve
- Close to the mean
Standard deviation
measuring how much the values tend to vary from the mean
Correlates for Intelligence Test Scores
- Predict academic success
- Predict number of years of schooling that a child will receive
- Somewhat weaker, predictors of level of employment and wealth except Western industrialized cultures
- Success in workplace
- Social and interpersonal skills
General Intelligence (g)
Charles Spearman
- Psychometric approach
- Single, underlying essence to intelligence that affects all kinds of intellectual performance
- Neural processing speed, working memory capacity, brain myelination
- Intrinsic to each individual and unchangeable
Three-Stratum Theory of Intelligence
John Carroll
*hierarchical array of abilities with g as a single factor at the apex, the third stratum
Cattell-Horn-Carroll (CHC) theory of cognitive abilities
factor analysis reveals three levels, each of which makes important contributions to understanding intelligence
- Reciprocal positive causal interactions between lower-level cognitive abilities-elements causing positive correlations with each other-created a higher-order g
- g emerged rather than present from birth
