Chp 10.1: Intelligence I Flashcards
intelligence
a concept that refers to individual differences in the ability to acquire knowledge, to think and reason effectively, and to deal adaptively with the environment
mental age
the mental level at which a child is performing as determined by a “standardized interview” in which the child responds to a series of questions
intelligence quotient (IQ)
originally defined as mental age (MA) divided by chronological age (CA) multiplied by 100 (IQ = (MA/CA) × 100); an IQ of 100 indicates an individual is average for their age group; IQ scores are today based on norms derived from people of various ages
Why do today’s intelligence tests no longer use the concept of mental age? How is IQ now defined?
- No longer used in current intelligence tests
- Concept works well for children, but not for adults
- As chronological age increases, mental age may not
- Current tests use a deviation score and compares a person’s performance to scores of others who are in the same age group
Who developed the first intelligence test?
Alfred Binet
- believed that intelligence involved complex thinking processes
- Influenced definition of intelligence
Galton’s Anthropometric Approach
Francis Galton
- tried to measure intelligence systematically
- relation between sensory abilities
Anthropometrics
“methods of measuring physical and mental variations in humans”
Entity theory
belief that intelligence is fixed
Incremental theory
belief that intelligence can be changed
