psych 315 - M2 Flashcards
History of Intelligence Testing
- Alfred Binet
- public education just started – wanted to identify students who needed more support
- wanted to find children who needed extra support (did not focus on the “why”)
- Louis Terman
- brought intelligence testing from France to North America
- started seeing intelligence as heritable (from genetics)
- adapted into Stanford-Binet Intelligence Test
Common IQ Tests
- Stanford-Binet Intelligence Test
- mean score of 100
- 1 general score from intelligence quotient
- different questions for different ages
- issue: some questions needed to know certian facts
- Wechsler Intelligence Scale for Children (WISC)
- had general score and 5 composite scores
- wanted a test for adults as well
- wanted test that was less linguistic-based and school-based (Binet focused too much on language, verbal abilities and facts from formal schooling
Different Theories of Intelligence
-
General Intelligence: intelligence is one underlying ability – can be split into sub-abilities but contribute overall to your general intelligence
- crystallized intelligence: factual knowledge
- fluid intelligence: ability to think on the spot and solve problems
-
Sternberg’s Theory of Successful Intelligence
- analytical intelligence: analyze and solve problems
- practical intelligence: street-smart
- creative intelligence: divergent thinking (# of solutions)
-
Gardner’s Multiple Intelligences
- 7-9 types of intelligences
- people have different strengths – and we should foster different strengths
- not fully supported (difficult to test)
Why are there individual differences in IQ?
-
gene environment correlations: our genes help us create environments that fit our predispositions
- passive effect: child and parent’s shared tendency leads to environment
- evocative effects: child’s genetic tendency cause them to evoke certain reactions from their environment
- active effects: child’s genetic tendency cause them to actively select environments
-
genetics
- monozygotic twins have similar intelligence levels
- genes get stronger as we get older due to gene environment correlations
-
environment
- school: more schooling = higher IQ scores
- IQ scores similar with grade-peers, not age-peers
- family environment: higher IQ for parents who provide stimulating environment / emotional responses / verbal and language communication / encouragement
-
socioeconomic status: higher SES = higher IQ
- not static: moves with your SES
- time period: i.e. Flynn Effect
- school: more schooling = higher IQ scores
is IQ testing helpful or dangerous?
- (+) predictor for job performance, health, attitudes
- (+) tool for research and policy decisions
- (-) eugenics background caused from IQ testing
- (-) IQ may not actually measure intelligence: sensitive to motivation, coaching / cultural biases
Group Differences in IQ scores
- girls do better in verbal (closer to average)
- boys do better in spatial / math (closer to extreme edges)
- white individuals score higher than black individuals
- why?
- culturally-biased tests
- social differences (different experiences, background, socioeconomic)
- stereotype threat
Stereotype Threat
- a psychological burden caused by the concern that one’s performance might confirm a negative stereotype about one’s group
- awareness of negative beliefs > stress response + negative thoughts (need self-regulation) + monitoring performance > impaired performance
- cognitive load — theres only so much you can focus on
Picho & Schmader (2018)
- comparing teenager expectations on stereotypes + your own beliefs on those stereotypes
- result: own endorsement does not matter, but researcher’s expectations on whether your demographic would do well or not matters
Mindsets about Intelligence
- fixed mindset (= entity theory): intelligence and talent are fixed at birth
-
growth mindset (= incremental theory): intelligence and talent can go up or down
- predicts response to challenges and failures: more resistant, will continue trying, will choose challenging courses
- predict academic outcomes: tend to do better academically
- formed through individual differences, but can be induced
- praise: you’re so good v you’re working so hard
- interventions: giving feedback
How do beliefs about intelligence impact academic achievement?
- children with growth mindset have better academic performance
- children from high SES: more resources → better performance
- children from low SES: less likely to have growth mindset
- BUT, when children low income families have growth mindset
→ good performance are even more pronounced
- BUT, when children low income families have growth mindset
Claro, Paunesku, & Dweck’s (2016)
- growth mindset tampers the effects of poverty on academic achievement
- academic achievement affected by socioeconomic background and psychological factors (= beliefs about ability)
- strong predictor of achievement: family income, growth mindset
- students from low-income are less likely to have growth mindset
- but those that do: acts as buffer on effects of poverty
- done on all 10th graders in Chile through national exam
- students with growth mindset outperform their peers at each family level
What does reading require?
- visual detection: detect symbols
- understanding the language
- symbolic understanding: understand word represents something else
- phonological recoding: symbol-sound correspondence
- visual-based retrieval: whole-word recognition
What does writing require?
- visual detection: detect symbols
- understanding the language
- symbolic understanding: understand word represents something else
- phonological recoding: symbol-sound correspondence
- visual-based retrieval: whole-word recognition
- fine motor skills
- organizing narrative
Stages of reading acquisition
-
stage 0: pre-reading
- [0-3] recognize and pretend to read books
- [3-4] know that letters have names (may know some), recognize print in environment (i.e. “stop” sign) interest in reading books
- [5] recognize upper and lowercase letters
-
phonological awareness: ability to recognize and analyze sound structure of spoken words
(i.e. what rhymes, what words start with same letter)
-
phonological awareness: ability to recognize and analyze sound structure of spoken words
-
stage 1: grade 1-2
- alphabetic principle: one letter corresponds to a sound (use for phonological recoding)
-
stage 2: grade 2-3
- gains reading fluency — faster and more efficient
-
stage 3+: grade 4
- more complex reading abilities
- reading to learn (not learning to read anymore)
Teaching children how to read
- informal: reading to children
- formal:
-
phonics / reading for decoding
- if only based on context, will not have skills to figure out new words in new context
-
whole-language instruction
- expose child to interesting stories, posters, books > will acquire reading from context
-
phonics / reading for decoding
Brain and Reading
-
visual word-form area: as we learn to read, this area starts to specialize and activate towards written words
- forms connections with auditory and visual brain system
-
neuronal recycling hypothesis: as we acquire written language → changes how brain responds to other things
- only so much space in your brain — language takes over what would be happening
- responds less to faces and objects, but now responds more to written words
Dyslexia
- dyslexia: reading ability is lower than expected based on IQ
- old theory: believed to be caused by visual impairment
- current causes:
- genetics
- phonological deficits
- influence of language — more for languages with deep orthographies
Contrasting social development theories
- Focus of stage
- F: each stage has specific zone in body with strongest urge
- E: each stage has central conflict to be resolved
- External contexts
- F: we are all born with powerful urges
- E: social environment interacts to shape development
- B: must take into account context of environment
- Difference in stages
- F: stages
- E: stages
- B: continuous
- Effect of interactions
- F: early interactions set up later development
- E: how we resolve conflict impact how we develop, and goes into adulthood
- B: development occurs within complex system of relationships
Freud’s Psychosexual Theory
-
we are all born with powerful urges
- id: unconscious sexual and aggressive urges that drives us to behave in certain ways (part of personality)
- ego: works to balance drive v societal expectations
- superego: biological drives in conflict with reality and societal expectations (reality and morality aspect of personality)
- how we resolve conflict between id, superego and ego will have continued influence in later development
- stages:
- each stage has specific zone in body with strongest urge
- child has to learn to gratify urges while balancing reality and morality
- not balancing it will have continual impact in development
Stages of Freud’s Psychosexual Theory
- [0-18mo] Oral
- id comes in as pleasure principle
- at end of stage, ego comes in as reality principle
- [18mo-3] Anal
- [3-6] Phallic
- superego comes in as morality principle
becomes more sensitive to morality of society (right v wrong)
- superego comes in as morality principle
- [6-12] Latency
- drives are fairly dormant
- [12+] Genital
Erikson’s Psychosocial Theory
- focused on Freud’s ego
- argues it does more than just balance the id and superego
- social environmental factors interact with ego to shape development to deal with expectations from society
- ego continues to have conflicts beyond childhood - development goes beyond childhood into adulthood
- stages of development
- at each stage, a central conflict has to be resolved
- how we resolve the conflict impacts how we develop
Stages of Erikson’s Psychosocial Theory
- [infancy, 0-1] trust v mistrust: can i trust the world?
- trust: parent will come help when needed
- mistrust: not getting consistency / comfort needed → will impact relationships throughout development
- [toddlerhood, 1-3.5] autonomy v shame/doubt: can i control my behaviours in the way society expects?
- i.e potty training
- [early childhood, 4-6] initiative v guilt: can i be independent from my parents?
- if parents give space: will grow to be independent
- if parents too involved: may develop guilt and not feel independent over behaviours
- [middle childhood, 6-puberty] industry v inferiority: can i master skills i need to adapt?
- mostly school-based: reading, counting, etc
- [adolescence] identity v role confusion: who am i?
- figuring out how to define yourself
- [young adult] intimacy v isolation: can I fully give myself to someone else?
- learn about intimate friendships and romantic relationships
- [middle age] generativity v stagnation: what can i offer generations to follow?
- tied to parenting / future generations
- whether your work has meaning to future generations
- [old age] integrity v despair: have I found contentment and satisfaction?
Bronfenbrenner’s bioecological model
- takes into account context: context impacts all interactions and relate with each other
- development occurs within a complex system of relationships
- Model:
- the child: comes with biologically-based dispositions that actively influence development
-
microsystem: immediate environment
(i.e. family, daycare, neighborhood) -
mesosystem: connection between aspects of microsystem
(i.e. relationship between mom and daycare -
exosystem: indirect environments
(i.e. mom’s stressful job — indirectly affects the child) - macrosystem: cultural values, laws, customs, resources
- chronosystem: time period and child’s age
