INTELLIGENCE & PSYCHOLOGICAL TESTING
1 TESTING
1.1 PSYCHOLOGICAL
1.1.1 Mental ability tests 1. Intelligence – measures general mental ability like one’s ability to solve problems, understand language, abstract ideas 2. Aptitude – specific mental abilities, also assess potential in certain areas. 3. Achievement – assess one’s knowledge of subjects like English and reading ability.
1.2 EVOLUTION
1.2.1 Sir Francis Galton (1869) – Studied upper class British families and concluded that intelligence was genetic because it ran in families. He did not consider the environment of the individuals.
1.2.1.1 Alfred Binet and Theodore Simon (1905) – Commissioned by the French Government to devise a way to identify children that needed remedial assistance in school – Result was the Binet-Simon Intelligence Scale – first intelligence test as we know it
1.2.1.1.1 Lewis Terman (1916) – U.S. – Revised Binet’s original test and published the Stanford-Binet Intelligence Scale – This test used the Intelligence Quotient (IQ) – IQ = MA/CA x 100
1.2.1.1.1.1 David Wechsler – Weschler worked in a New York hospital and needed to assess adults – Wechsler Adult Intelligence Scale (WAIS) – First done in 1939 – Later made a children’s version - Wechsler Intelligence Scale for Children (WISC)
2 KEY CONCEPTS
2.1 Standardization - refers to having uniform standards for administering and scoring a test. Test norms – based on large studies that show how one’s score compares to the average score other’s received. Raw Score – score on a test. Percentile score – indicates the percentage of people who score at or below the test taker’s score. Standardization group – group of people the norms are based on
3 R&V
3.1 Reliability – Whether or not a psychological test gives consistent measurements.
3.2 Validity – ability of a test to measure what it was designed to measure More recently the term validity is used when discussing what the test is used for
4 CCC
4.1 Content validity – degree to which the content of a test covers the topic area
4.2 Criterion-related validity – if it correlates well with another measure of the test
4.3 Construct validity – degree to which the test measures a particular trait.
5 DISABILITY
5.1 4 LEVELS
5.1.1 1. Mild - (51-70 IQ) Can attain grade 6 education and benefit from special education. 2. Moderate (36-50 IQ) Attain grade 2-6 - Can be semi-independent if in a sheltered environment but need help even with mild stress. 3. Severe: (20-35) Limited speech, need training on toileting. 4. Profound: (below 20) Little or no speech, not toilet trained.
5.2 INTELLECTUAL
5.2.1 Down Syndrome - physical characteristics, extra chromosome 21
5.2.1.1 PKU - Inability to metabolize phenlalanine.
5.2.1.1.1 Fragile X syndrome - Fragile area of the X Chromosome has area that is repeated.
5.2.1.1.1.1 Hydrocephaly - too much cerebrospinal fluid around brain destroys tissue and become ID.
5.2.2 GIFTED
5.2.2.1 To be considered gifted, on must have an IQ 2 standard deviations above the mean (IQ score of 130 - 170)
6 HEREDITY & ENVIRONMENT STUDIES
6.1 Family - Level of intelligence runs in families.
6.1.1 Twins – Identical twins are compared to fraternal twins in order to study the role of genetics considering that identical twins have 100% of the same genes.
6.1.1.1 Adoption - If adoptive children are more like their biological parents, there is more genetic influence.
6.1.1.1.1 Environmental Deprivation - Children raised in orphanages and other deprived situations have lower IQ scores than average.
