Language and Thought L7 Flashcards
What is a definition of intellegence?
The ability to acquire knowledge, to think and
reason effectively and to deal adaptively with the
environment
What is intelligence?
- Set of mental abilities
- Acquire and use knowledge
- Plan and solve problems by taking thought
- Adapt effectively with the environment and learn
(quickly) from experience
What was Samuel Morton’s contribution to the ideas behind intelligence?
1820s‐1850s):
- Believed head size related to intelligence (the more the better)
- Ranking of races, bias towards Europeans being more intelligent
- Data skewed to not include extremes?
What was Paul Brocca’s contribution to intelligence?
(1824‐1880):
- weighed brains of cadavers
- compared groups
- believed heavier brain = more intelligence
- He corrected for body size so that race differences weren’t a factor but not for gender (women believed to be inferior)
Is a bigger brain actually better?
- Correlation between brain size and intelligence = .33
- Higher for females than males (within the groups not between)
- Higher for adults than children
- Only a rough guide
What is a better measure of intelligence using the brain then IQ?
-Brains of intelligent people are more efficient i.e. there is better quality of connections and processing between neurons
What can be seen when looking at the brain’s of intelligent children?
-Cortex of highly able children starts off thinner at age 7, reaches peak thickness later → extended window of opportunity for developing high-level cognitive circuits?
What was Sir Francis Galton (1822‐1911) contribution to intelligence?
-Viewed intelligence as hereditary
-Coined the term “eugenics” (Selective breeding of races creates a perfect society)
-Intelligence and preeminence were products of evolution (survival of the fittest)
-Made first systematic attempts to measure intelligence
by observing behaviour
What did Francis Galton view as the building blocks for intelligence?
Simple, perceptual sensory motor abilities
- ability to perceive something
- quickness of response
- strength (believed in the “weaker sex”)
What did Francis Galton find when he tried to take measures of intelligence from the population?
Examined performance on tasks, found:
-No relation to social class
-Developed statistical techniques → Pearson’s r
correlation coefficient
What was Alfred Binet’s (1857-1911) contribution to intelligence?
-French scholar: Pioneered intelligence
testing
-Father of modern day intelligence testing (Stanford Binet IQ test)
-Viewed Intelligence as a psychological construct
What was the purpose of the intelligence test Alfred Binet developed/ what did he believe in regards to intelligence?
- Developed test to predict school success in order to help children who were struggling
- Started by measuring head size then came to believe that intelligence was performance on complex tasks, with many levels of difficulty
- Believed that intelligence was a GENERAL ABILITY, not just the accumulation of knowledge
- Did not start out with a precise definition or theory of intelligence and tried to eliminate bias
- Used a 1:1 approach when did testing
What are some examples of the types of tasks Alfred Binet got students to do?
- Copying a drawing
- Repeating digits (memory)
- Making change with coins
- Comprehension
In Alfred Binet’s testing were scores the be all and end all?
No, scores were devices designed to help but do not mark children as inherently incapable
What was the earliest form of an IQ score, who developed it?
- Alfred Binet
- Mental Age/Chronological Age x 100
