Exam 4 Flashcards
What is intelligence?
Intelligence is the general capacity to understand ideas, think abstractly, reason, solve problems, and learn.
How has cognitive science been historically biased against women? Consider phrenology, head circumference and brain weight/volume, and fMRI and how they have been used to promote essential and sexist beliefs about gender.
Phrenology (a pseudoscience): infer intellectual and psychological attributes from skull
Head circumference, brain weight/volume (despite no link to intelligence)
fMRI shows some differences in size/density but overall similarity
Neurosexism (Chapter 2)
Structure =/= function
What is an intelligence quotient (IQ) and how is it interpreted? How does this methodology differ from previous approaches (in design)?
20th century: pivot toward cognitive tests to measure intelligence (eugenics)
Intelligence quotient (IQ): standardized score representing a person’s level of intelligence relative to same-age peers.
This methodology differs from previous approaches, by trying to measure intelligence through a test rather than measuring, fMRIs, and weight/volume of the brain
What does IQ research tell us about sex differences in intelligence?
No differences in men’s and women’s average IQ
What is the Flynn effect? Are there sex differences in this effect?
The Flynn effect is the increase of IQ over time.
Flynn effect shows no sex differences (IQ increasing at similar rate for men and women, no)
What overall conclusions can be made about the history of cognitive ability research?
The history of cognitive ability research has been overall a controversial one, but it is finally being used in a way to show cognitive differences though all on the premise that sex is binary.
What is general intelligence (“g”)? What does it predict? Are there sex differences (explain)?
General intelligence (“g”): ability in one domain (e.g., reading comprehension) should positively correlate with others (e.g., pattern recognition, working memory)
Predicts academic/job performance, health, longevity
Stable over lifespan
Moderately heritable
Most studies find small to no sex differences in “g”
Most IQ tests designed to be unbiased by sex – so the cognitive abilities that are sex differentiated are not tested in IQ tests.
What is an effect size (“d” value)? How is an effect size for a sex difference interpreted, in terms of direction and strength?
- Practice describing the following d values (direction and strength): -.49; .30; .05; -.88
An effect size is a value measuring the strength of the relationship between two variables in a population
Positive d = on average, men perform better than women
Negative d = on average, women perform better than men
0.00-0.10 - close to zero
0.11-0.35 - small
0.36-0.65 - medium
0.66-1.00 - large
> 1.00 - very large
What is the general pattern of sex differences in verbal performance? Quantitative? Visual-spatial?
Verbal, d = -0.11
(small to moderate)
Tends to favor women
Quantitative, d = 0.00
(close to zero or small)
Visual-spatial, d = 0.40
(moderate to large)
Tends to favor men
What is the sex difference in vocabulary (and when does it arise vs. disappear)?
Vocabulary: Small female advantage (early childhood only)
What is meant by verbal fluency? Who does the sex difference favor, men or women?
Verbal fluency (generation of words): female advantage (small to moderate).
What is the sex difference in reading and writing?
Reading: cross-culturally, small to moderate difference favoring girls
Sex difference increases with age and women’s educational opportunities
Writing: Moderate sex difference favoring girls
What is meant by verbal reasoning? How does this sex difference differ from the other verbal skills, and why might this be?
Verbal reasoning (understand and analyze concepts): small male advantage (often involves visual-spatial processing)
Where do women have a small quantitative advantage? At what ages?
Age 5-10: Small female advantage for computational ability
Where do men have a modest quantitative advantage? At what ages?
Age 15-25: Modest male advantage for complex problem solving
What is meant by mental rotation ability? Who does it tend to favor?
Mental rotation ability (being able to mentally rotate an object in one’s mind so that they can compare it to images of that object seeing which ones are the same object): moderate to large, favors men
What is spatial perception? Who does this sex difference favor?
Spatial perception: Male advantage small (childhood) to moderate (adulthood)
Spatial perception: the ability to perceive, understand, and remember spatial relations between objects in 3D space
What is spatial visualization? Are men or women better spatial visualizers, and when does this difference emerge?
Spatial visualization: small male advantage (emerges in teens)
Spatial visualization: ability to represent and manipulate two- and three-dimensional objects mentally; manipulate spatial information sequentially
What is meant by spatial location memory? How does this sex difference differ from other visual-spatial skills?
Spatial location memory (remembering where objects are): Small difference favoring women, differs because it favors women
What is the greater male variability hypothesis? What is the evidence for or against this phenomenon?
Greater male variability hypothesis: men show greater within-group variability in cognitive performance (more outliers) than women.
For:
Math SAT: boys make up higher proportion of top scorers; greater variation than girls
Higher rates of learning disabilities, developmental disorders in males
Alleles on X chromosome linked to sex differences in lower tail (e.g., disability)
Against:
Not present for all cognitive measures (e.g., verbal performance)
Not present across all racial/ethnic groups, cultures
Responsive to nation-level gender equality
What overall conclusions can be made about men vs. women’s cognitive abilities?
There are overall differences in cognitive abilities between men and women though most of them are small or close-to-zero. Also, it could reflect nature or nurture.
Culture can help us infer the extent to which cognitive abilities are due to nurture (e.g., socialization) vs. nature (e.g., genetics). For which sex difference do we see the greatest amount of cross-cultural variation (verbal, quantitative, or visual-spatial)? Which sex differences tend to be more consistent across cultures?
Nurture: sex differences vary across cultures.
Several large-scale studies show cross-cultural variation in the size of cognitive sex differences
Varies based on gender equality
Especially evident with math
Nature: sex differences hold across cultures.
Verbal and visual-spatial differences show less cross-cultural variation
Education debt: what is it? How does it disproportionately disadvantage low-income or racial minorities students?
Education debt: ongoing, cumulative lack of investment in education of low-income and racial minority students
More resources provided to majority White (vs. Black/Latinx) schools
Produces structural inequalities in education
Leads to poorer outcomes and achievement gaps
Math anxiety: what is the sex difference here? Who is more anxious about math vs. who is more confident / positive about math? How can socializers (i.e., parents, female teachers) affect girls’ math stereotypes and performance?
Math anxiety d = -.23
Math self-confidence d = .27
Positive attitudes about math d = .10 - .33
Socializers’ own math anxiety can increase girls’ math stereotypes and worsen math performance
Female teachers
Parents
