Q

What criteria should be met to be considered a good test?

A
  1. validity ( through having the right testing criteria)

Q

How do we check for consistency

A

Giving the subjects the test right after taking it. If it is consistent there should not be a significant difference in the recorded results

25
What is emotional intelligence?
The ability to perceive, manage, understand and use emotions
26
What are the 2 ways people have tried to neurologically measure intelligence
1. brain size and structure ( how many convolutions) | 2. brain function ( looking at how fast people respond to spatial problems)
27
What is the difference between aptitude and achievement tests
aptitude: to predict how well a person would do at something achievement: to test how well someone has learnt something
28
What were things tested on the WAIS tests?
1. similarities 2. block design 3. vocabulary 4. letter-number sequencing
29
What is the Flynn effect
The increase in mean IQ scores over the centuries
30
What is predictive validity?
It is when IQ tests are able to predict future performance
31
What is content validity?
When a valid test contains the right criteria
32
What is fluid intelligence?
It is the intelligence that declines with age. Involved in problem solving and logic reasoning
33
What is crystallized intelligence?
Intelligence that increases with age. This involves linguistic and analogy building
34
What is a longitudinal study?
It is a study that follows the same people across some years
35
What is a cross-sectional study
It refers to a study involving people from different ages being sampled at one time
36
What did cross-sectional studies on intelligence show?
A decline in intelligence with age
37
What did longitudinal studies on intelligence show?
A stable level of intelligence with age
38
What does intelligence have to do with life span?
More intelligent people lead healthier and longer lives
39
What is intellectual disability?
It refers to a condition where a person has a limited mental ability. it is indicated by a score of 70 or less
40
What is heritability?
The proportion of differences among individuals that we can attribute to genes.
41
Can the heritability of a trait be different?
Yes it can be varied, as it depends on the range of populations and environment
42
People with down syndrome have an extra chromosome of what # chromosome?
people with down syndrome have an extra chromosome 21
43
What is the conclusion from twin and adoption studies for intelligence testing?
some aspects of intelligence is inherited as twins that are grow up apart and together have more similar IQ scores than that of siblings reared together
44
How does nurture play a role in children's performance?
1. malnutrition would depress the intelligence of children | 2.
45
Is there a difference in intelligence among genders ?
The average IQ scores are about the same, with the range for females being more stable around the average while males have a great number of people at both ends of the spectrum
46
How can an intelligence test be bias?
It would be bias if the performance differences is caused by cultural experiences ( people with certain cultural experiences have greater test scores)
47
What is does it mean for a test to be biased in terms of it's validity
eg. if a test predicts what it is supposed to predict ( SAT may be culturally bias to those having gone through the US system but it still does accurately predict success in college)
48
What is the stereotype effect?
A self-confirming concern that one will be evaluated based on a negative stereotype
49
Is heritability specific to an individual
No. heritability is not specific to an individual
50
What is hereditability?
It is the proportion of performance variance in a sample attributed by the variability in genes
51
How is the heritability of intelligence studied?
1. twin studies 2. adoption studies 3. molecular genetics
52
How many percent of a person's intelligence score variation is inherited?
50-75%
53
What is behavioural genetics?
study of genetic influence on behavior
54
what kind of study are twin and adoption studies?
both rely on correlations between pairs of people who vary in their genetic association
55
What research was done by Tryon and when?
He did selective breeding of rats breeding for maze running abilities in 1942
56
What research did Cooper and Zubek do and when
Done in 1958. Environment can overwhelm genetic differences
57
What can animals be bred for?
-activity levels -exploratory behavior -eating behavior aggressive behavior wariness
58
What are the genetic similarities between: - monozygotic twins - dizygotic twins - parent and child - parent and adopted child
100% 50% 50% 0%
59
What outcomes from twin studies would support that genetics plays a role in intelligence?
- if correlations are higher between monozygotic twins regardless if they were raised apart or reared in different environments
60
What outcomes from twin studies would support that the environment plays a role in intelligence?
if the intelligence scores from MZ and DZ twins are highly correlational when reared in the same environment
61
What is the formula for heritability?
(MZ in same environment-DZ in same environment) = h^2
62
What are the weaknesses with Twin studies?
Identical twins share the same appearance ( may be treated differently due to appearance). MZ are always the same sex; DZ are not cannot tell if there really are environmental differences for twins that are reared apart because adopted families share a lot of similarities
63
what does heritability estimates not tell us?
- does not tell us genetic influence within an individual - does not tell us how genes influence behavior - does not tell us that intelligence can be changed - does not explain for group differences in scores
64
how many generations of rat breeding did it take to see signifcant genetic differences among rats?
7 generations
65
What are the outcomes of twin studies?
in good environments with high SES, heritability scores are higher , shared environment does not explain much in poor environments, genetic heritability is low (no potential for these people to shine). environment explains more
66
what can be used to explain the environmental differences with intelligence scores
1. differences in resources 2. discrimination and bias 3. socialization differences 4. stereotype threats
67
What was the theory proposed by Carol Dweck
There are 2 mindsets on how we think about intelligence
68
What are the 2 mindsets for intelligence
1. Real Mindset(intelligence is fixed) | 2. Growth Mindset( intelligence can be developed)
69
What is another name for growth mindset
incremental theory of intelligence
70
What is another name for fixed mindset
entity theory of intelligence
