Week 9: Intelligence & Morality 1 Flashcards
Intelligence: Describes Interventions & Policies regarding individual differences
- Identify individuals with potential
- Identify individuals who are at risk
- Provide support and opportunities to people who could use them best
How do Intelligence Tests Work? Name the main 3
1) Rely on very large samples
2) Test a variety of tasks
3) Compare individual performance to norms (by age)
What causes differences in IQ?
Genetic contribution: More relatedness = higher correlation
(Identical twins being raised together vs siblings raised together)
Environmental contributions: Genetics doesn’t explain all (e.g., fraternal twins > siblings)
Define Heritability
proportions of observed variability that can be explained by genetic inheritance
Aside from heritability for IQ, what influences the 50% of variation?
This is explained by the environment
- Effects of shared environment (e.g., children in the same family)
- Effects of non-shared environment
- Different experiences within the family
- Different experiences/environmental factors outside the family
Can IG Heritability vary by socioeconomic status?
YES
What was the connection between SES(socioeconomic status) and IQ Heritability?
- For children in very low-income families, the estimated genetic influence on IQ is close to zero.
- Minimal expected environment
What is the minimal expected environment?
If conditions are very impoverished, children do not attain their genetic potential
What are the main problems with IQ tests?
- Content of IQ tests is designed to predict performance
- Features other than “general intelligence” correlate as much with academic success (e.g., Self-discipline, executive function)
Describe the study of Self Discipline: Delay of Gratification
- Young children(4-5 years old) were placed in a room with a marshmallow and were asked to wait for the researcher to come back so they could have 2 marshmallows
- It was intended to measure the academic achievement in high school
- Self-control may matter more than IQ. “When IQ and self-discipline are entered simultaneously in a multiple regression analysis, self-discipline accounted for almost twice as much variance in GPA”.
Who did the children prefer: the reliable experimenter who says she will bring crayons and does or the unreliable experimenter who says she will bring crayons and doesn’t?
The graph shows that the children prefer the reliable experimenter.
Describe the Carolina Abecedarian Study (Ramey & Campbell, 1984)
- Infants from low-income families were randomly assigned to 1) High-quality infant intervention (0-3years) 2) No infant intervention
- Half of each of those groups was later assigned to 1) School-aged intervention (5-8years) 2) No school-aged intervention
- Main questions: 1) Do interventions improve cognitive outcomes?
2) Does the timing of intervention experience matter?
Describe the two folk theories of intelligence
1) Intelligence as fixed: Entity View
- You are smart or not smart
-Working hard indicates a lack of intelligence
- Think of this as a fixed mindset
2) Intelligence as acquired: Incremental view
- Intelligence is malleable
-You get smarter by practicing
IMPORTANT TO NOTE: Folk theories do not correlate with intellectual ability, but they affect performance
How do incremental theorists act when faced with a challenge?
Incremental theorists can thrive because they see failure and challenge as learning opportunities
How do entity theorists act when faced with a challenge?
Entity theorists see failure as indicating a lack of intelligence or ability, so challenges are threatening
