IQ (In words)
Intelligence Quotient
Who developed the idea that intelligence captures a common general cognitive ability?
Charle’s Spearman
If a kid is good at math, they will also be good at reading, and so on…
“Jack of all trades” is associated with Spearman’s ____?
Spearman’s g
An all-purpose ability to do well on cognitive tasks, to solve problems, and to learn from experience.
intelligence
Intelligence tests that are intended to be culturally unbiased.
Culture-Fair Tests
SUMMARY: Cultural Bias in Testing
Early questions on testing did not measure the knowledge necessary to adapt to one’s environment or to be intelligent. Questions were tailored to urban and white, English-speaking Americans instead of rural neighborhoods, Hispanic, or African Americans, or those with different languages. Even when “culture-fair tests” were developed, they still didn’t adequately accommodate everyone and bias was still present. The variable that shares the strongest correlation with IQ is years of education. However, other environmental factors can also influence intelligence.
Cultural -Fair test that contains no verbal questions
Raven Progressive Matrices Test
Refers to an organism’s genetic material
Genotypes
Refers to the actual characteristics the organism pocesses.
Phenotypes
The proportion of observable differences in a group that can be explained by differences in the genes of the group’s members.
Heritability
- ) TRUE or FALSE
- ) Why is it true or false?
50% of an individual person’s intelligence is caused by genes.
- ) FALSE
- ) Flase bc heritability is a statistic that provides info about a group, not an individual.
- ) TRUE or FALSE?
- ) 2.) Why is it true or false?
A person’s intelligence is fixed by genes.
- ) FALSE
- ) False bc Genes interact w/ environmental factors to determine intelligence.
Intelligence is a _______ ________ trait, meaning that a large # of genetic characteristics are involved in intelligence.
(2 words)
Polygenic trait
What 4 specific experiences in childhood can influence IQ?
Dietary Supplements
Educational Interventions
Interactive Reading
Preschool
When pregnant women, nursing mothers, and infants received _____ milligram supplements of Omega-3 fatty acids, the supplements led to an increase in children’s IQ.
1,000 Milligrams
Learning to play a musical instrument predicts a ___ point increase in IQ.
4- POINT INCREASE
For economically disadvantaged children, sending a kid to preschool increased their IQ by more than ___ points.
4 points or 7 points
A phenomenon around the world that shows the effect of education on intelligence with IQ test scores increasing is called _____ ______.
(2 words)
Flynn Effect
SUMMARY: Genetic & Environmental Influences on Intelligence
Genes are not the only determining factor for intelligence. Several outside factors dictate IQ as well. Such as; a person’s education, environment, eating habits (as children), dietary supplements. The results for heritability as it relates to IQ can be unpredictable based on different groups. For example, if a group lives in wealthy area heritability estimates for intelligence may be high because of the environment. Whereas, if a group lives in an area with wealthy individuals as well as less wealthy or stable environments, the genetic characteristics may be less predictive in regards to intelligence due to environmental factors. The word “intelligent” is not only described as people, but also as behaviors.
Possessing high intelligence (an IQ of 130 or higher) and/or superior talent in a particular area is called _________.
Gifted
Begun in the 1970s, this group of 320 participants (under the age of 13 years old) were considered to represent the Top 1 in 10,000 IQ scores with an average IQ of 180.
SMPY
The Study of Mathematically Precocious Youth
SUMMARY: Extremes of intelligence- Giftedness
A study conducted by Lewis Terman included 1500 students called “Termites” whose IQs averaged 150 which placed them in the top 1%. In comparing the study to the longitudinal study of gifted children called SMPY study years later, the study showed that SMPY participants were doing remarkable things with their life compared to the Termites. The genes and environmental experiences that explain normal-range intelligence, also explain exceptional intelligence. aside from Cognitive ability, being nominated to test for gifted education programs sometimes relies on someone else’s social perception.
