Assessing Intelligence
Alfred Binet
• Paris, 1905
• Looked for mental age
• The goal of understanding intelligence was to predict how well children would do in school
Lewis Terman
• Revised the age standards for children
• Renamed test the Stanford – Binet Test (Terman was a professor at Stanford)
Intelligence Quotient
• William Stern derived the IQ from tests like the Stanford – Binet
IQ= Mental ageChronological age
Multiplied by 100
Modern Tests
• Aptitude tests• Achievement tests• WAIS, David
Weschler: tried to test more than just verbal intelligence
• Performance portion + verbal
Standardization
• People that take tests are compared against the sample group, “standardization group”
• Average IQ is 100• Average range is 85
– 115 • Koko had an IQ of 85
Reliability
• How a test yields consistent results
• Try to make an individuals scores correlate
• Test – retest or split – half scores are 2 ways to check reliability
Validity
• How well a test measures what it’s supposed to measure
• Test based on criterion
Extremes of Intelligence
• Below average 85 – 70• Mental retardation
below 70• Majority of people
classified as mentally retarded can live on their own, with assistance, and they can contribute valuable skills to society
Breakdown of Mental Retardation
• Mild Retardation:– Low 50s – 70s
• Function as an 8 year-old
