Perspectives on Intelligence Unit 9 Lecture 2 Flashcards
Charles Spearman
- The idea that intelligence should be thought of as a single trait
- He developed a technique called Factor Analysis
Ex) Imagine having a measure for the physical dimensions for a bunch of people. You might have measures of head, foot, hand size, weight circumference etc. If all of these measures correlate with one another, it might be sensible to think that some general variable underlies all of them. If so all of these members could be captured by a single number that represents the general trait of body size.
(G) or GIF
General Intelligence Factor (or g)
General Intelligence Factor (or g)
- Represents their degree of mental energy, brain power
Ex) The blue ovals represents children’s performance on different academic subjects that are correlated to justify thinking that one factor, called g, underlies them all
Things that are correlated with g
The General Intelligence Factor (g), as measured by IQ tests has a .50 correlation with high school and university grades IQ scores are also correlated with: Lifetime Earnings # of years of education Lifespan Perceptual Judgment Speed Capacity for Impulse Control Success in Finding a job
G is not perfectly correlated with different _________
academic skills
What is the definition for what Spearman called s?
The part of children’s performance on different academic subjects that don’t correlate with one another
s represents what?
Individual’s subject-specific levels of intelligence
Louis Thurstone
Investigated the concept of g more carefully and identified that it was made up of seven independent clusters of primary mental abilities.
Lois Thurston came up with what 7 mental abilities?
- Word Fluency, Verbal Comprehension, Numeric Abilities, Spatial Visualization, Memory, Perceptual Speed, Reasoning
- ## They are distinct from one and other but also related to one and other.
Hierarchical Model of Intelligence
A the top of the hierarchy there is g (general intelligence factor)
The second level represents Thurstone’s 7 Primary Mental Abilities
The lowest level represents subject specific intelligence
Fluid Intelligence (Gf)
- The ease by which we can learn new information and find solutions to unfamiliar problems
- Refers to our potential for learning new things and adapting to novelty
Crystallized Intelligence (Gc)
Our ability to use our past experience and knowledge we have already acquired to complete tasks.
Robert Sternberg
Tried to capture forms of intelligence that were different from the ones that promote success in academic settings
The Triarchic Theory of Intelligence
- Analytical (Books Smarts)
The academic, “g type” of intelligence that most intelligence tests measure - Practical (Street Smarts)
Flexible problem solving in the real world beyond the classroom - Creative (Creativity)
The ability to solve completely new problems and to generate unique ideas
Howard Gardner
Noted the existence of savants
