Chapter 9 Flashcards
Boring definition of intelligence
Intelligence is whatever intelligence tests measure
Galton’s definition of intelligence
Intelligence is the byproduct of sensory capacity people with better senses, hearing and vision acquire more knowledge because most knowledge first comes through the senses
Research showed sensory abilities don’t seem to be strongly related to one another or to overall intelligence
Intelligence test
Diagnostic tool designed to measure overall thinking ability
Abstract thinking
Capacity to understand, hypothetical concepts
Binette and Simone
-designed the first intelligence test to distinguish students home, teachers perceived a slow learners from other students
Focussed on higher mental processes, reasoning, understanding, and judgement
Most now agree that intelligence is related to the capacity to understand the theoretical concepts abstract thinking
Spearman
General intelligence accounts for overall differences in intellect among people (g) “ individual differences”
Specific abilities, particular ability level in a narrow domain
Ex: some people are better overall athletes (g) , but some athletes excel in certain domains like soccer basketball (s)
Even if we’re really smart high in overall G we might flunk spatial problems because we have a specific deficiency
Cattel and horn
-theorized intelligence is a mix of two capacities
Fluid intelligence: capacity to learn new ways of solving problems
Crystallized intelligence : accumulated knowledge of the world acquired overtime
Fluid intelligence flows into crystallized intelligence overtime
Fluid intelligence likely declines in advanced ageing while crystallize intelligence might stay relatively stable or even increase
Multiple intelligences Gardner
According to Gardner, individuals vary in the type of intelligences at which they excel
Argued the autistic savants (exceptional ability in a limited domain) provided support for these different types of intelligence
Frames of mind
According to Gardner, these were different ways of thinking about the world for him. Each frame of mind is a different and fully independent intelligence.
Gardeners eight different intelligences
Linguistic: speak and write well
Logicomathematical; use logic and mathematic skills to solve problems
Spatial: think and reasonable object objects in three-dimensional space
Musical: perform, understand and enjoy music
Bodily kinaesthetic: Manipulate the body in sports dance, or other physical endeavors.
Interpersonal : understand and interact effectively with other others
Intrapersonal understand and possess insight into oneself
Natural naturalistic recognize identify and understand animals plants and other living things
Exist in intelligence, the ability to grasp deep philosophical ideas like the meaning of life
Triarchic model
Model of intelligence proposed by Sternberg positioning, three distinct types of intelligence analytical, practical and creative
Analytical intelligence: reason logically or booksmart
Practical intelligence : solve real world problems, or streetsmart
Creative intelligence ability to come up with novel and effective answers creativity
Has several weaknesses : practical intelligence is not independent of G
Biological basis of intelligence
Speed of information processing is related to intelligence
Calculating IQ
The Stanford Binet test compares the performance to population norms
Intelligent quotient: calculated by mental age/chronological age x100
Calculating IQ
The original IQ measure compared a persons chronological age to their mental age (age corresponding to the average individuals performance on a intelligence test
This approach works for children, but not adult adults. Intelligence peaks early 16 years for chronological age keeps increasing.
Modern IQ tests get around this problem by using deviation IQ : each person score is compared to what is normal for their age group
Eugenic movement
Improve a populations, genetic stock by encouraging those with good genes to reproduce, discouraging those with bad genes from reproducing
Forcible, sterilization and immigration laws had tragic impacts on society
WAIS
IQ testing today
Most commonly used IQ test for adult adult adults, which consists of 15 subset used to generate five scores
-overall IQ
-working memory
-Processing speed
-perceptual reasoning
-verbal comprehension
Culture fair IQ tests
Consist of abstract reasoning items that don’t depend on language example: ravens, progressive, matrixes starts off easy and becomes difficult
Intellectual disability
Characterized by childhood onset of low IQ below about 70 and inability to engage in adequate daily functioning
Four levels, mild, moderate, severe and profound
Termites
German study of intelligent children show that intelligent people were not more likely to burn out or have a mental illness
Dweck growth mindset theory
Dollars that think IQ is fixed tend to take less academic risks, challenging themselves less
Flynn effect
Average IQ of the population has been rising by about three points every 10 years
Most likely the result of environmental changes increased test, sophistication, increase complexity of modern world, nutrition, and changes at home and school
Gender differences in IQ
Females tend to do better on verbal tasks and recognizing emotions in others
Males tend to do better on spatial ability tasks like mental rotation and geography most appear to be due to environmental differences as environment improves differences almost vanish in ethnic differences in IQ
Within group heritability
Extent to which the variability of a trait within a group is genetically influenced
Equal environments show equal IQs
Between group heritability
Extent to which differences in a trait between groups is genetically influenced
