Goals
- Summarize the characteristics of a scientifically valid intelligence test
- Explain how stereotype threat and stereotype lift impact performance
- Understand the broad definition that intelligence is the ability to adapt
- Recognize the theory of multiple intelligences and give two examples from this theory
What is intelligence?
For decades, “intelligence” was referred only to cognitive intelligence that we aimed to measure statistically.
General (g) intelligence
Basic ability that underlies the performance of different varieties of intellectual tasks.
- Such as working memory
- Reading comprehension
Can leave people behind--people who have different domains of intelligence.
Specific (s) intelligence
Measure of specific skills in narrow domains.
- A math test
- A sports performance exam
What's a good test of "intelligence?"
- Reliable
- Consistent over time
- Someone who take the same test gets the same results.
- Valid
- Actually measures what we think it measures.
- Domain is consistent.
- Accurately measures depression when testing for depression.
- Standardized
- Has been given to many people of many ages in many circumstances
Wechsler Adult Intelligence Scale
- Gives a Full Scale Intelligence Quotient (FSIQ) based on the sum of
- Verbal IQ
- Verbal Comprehension Index
- Working Memory Index
- Performance IQ
- Perceptional Reasoning Index
- Processing Speed Index
- Verbal IQ
Sample WAIS (IQ) Tests
- Similarities
- How are "two" and "seven" alike?
- Block design
- Make these blocks look like this picture
- Digit symbol substitution test
- Digit span test
Failures of IQ Tests
- Doesn't test domain knowledge.
- Farmers or people who grew up poor are not going to do as well.
- Bias against people who are neurodiverse.
Stereotypes impact our performance
-
Stereotype threat
- Men vs. Women on math tests
- Men are told they are better at math, so when women know this, they tend to do worse on math.
- Same with sports.
- Men are told they are better at math, so when women know this, they tend to do worse on math.
- Someone who was told they are not smart generally see that stereotype true.
- Someone who grew up with autism is likely to perform worse.
- An individual’s expectation that negative stereotypes about their member group will adversely influence others’ judgments of their performance and that a poor performance will reflect badly on the member group.
- Men vs. Women on math tests
-
Stereotype lift
- A positive stereotype leads to increased performance.
- People who are told they are smart generally perform better.
- A positive stereotype leads to increased performance.
Theory of Multiple Intelligences
More than just basic "cognition intelligence" horsepower. There are different forms of intelligence:
- Ability to adapt
- Interpersonal: Other
- Intrapersonal: Self
Intelligence | Description |
---|---|
Linguistic | Speaking and writing. |
Logico-mathematical | Using logic and mathematical skills to solve problems. |
Spatial | Thinking and reasoning about objects in three dimensions. |
Musical | Performing and enjoying music. |
Kinesthetic | Moving the body such as in sports, dance, or other physical activities. |
Interpersonal | Understanding and interacting effectively with others. |
Intrapersonal | Having insight into the self. |
Naturalistic | Recognizing, identifying, and understanding animals, plants, and other living things. |
Case study
- Middle aged at time of study, cisgender male
- Born, raised, and continues to live in Alabama
- Single father of "the smartest boy in his class."
- Former college football player, Vietnam veteran, and Medal of Honor recipient.
- IQ = 75
