EXAM 3 Flashcards
Circle of thought
World -> describe -> elaborate -> decide -> plan -> act ->
(thinking processes are distributed throughout the brain; MAINLY FRONTAL LOBE!)
Concepts
Categories of objects, events, or ideas with common properties, basic building blocks of thought
Formal concepts
Formed by logical, specific rules
(example: square or car)
Natrual/abstract concepts
- No fixed sets of defining facts
- formed by everyday life experiences
(EX: everyday life experiences; beauty; learning to walk)
Prototype (prototypical member)
- typical member of a category
- a member of natural concept that has most (if not all) characteristics
(EI: we view a car w four wheels as prototypical)
Proposition
Mental representations that express relationships between concepts; can be true or false
chips < candy
candy < milkshake
chips < milkshake
Schemas
Sets of propositions that create generalizations and expectations about categories of objects, places, events, and people
(EX: All grandmas are old, have gray hair, and bake cookies; or you can start a car that you have never been in before)
Scripts
Schemas about familiar activities and situations that guide behavior in those situations
(ex: restaurant script - fast food joints have you pay before eating; fancier places make you pay after)
Mental Images
Mental representations of visual information (includes visual, auditory ect)
(ex: hearing a desc. of your blind date give you a mental image of them)
Mental Models
Representations of how concepts relate to each other in the real world; can be correct or incorrect
(think of the driver tossing his cigarette out and it landing back in their car)
Cognitive map
Mental representations of familiar parts of your world
(ex: rerouting to get to class faster if your normal route is blocked)
Formal Reasoning
Logic may be correct, but initial assumption may be incorrect
response to:
all gun owners (A) are people (B)
all criminals (C) are people (B)
JUST BECAUSE A == B AND C == B DOES NOT MEAN A == C
so
All gun owners (A) are all criminals (C)
Is a FALSE statement
Hill climbing strategy
Keep progressing towards the goal; taking what seems like the most straightforward path to reach it
Tower Of Hanoi
A perfect example of the FLAWS OF HILL CLIMBING! In over to solve you must work BACKWARDS
Means end analysis
- Starts by comparing the current state + the goal state
- “Decomposition”- breaking up the problem into “Sub Problems”
Work Backwards
Focusing on the goal rather than the current state + working backward from the goal
(like tower of Hanoi)
Find Analogies
We are reminded of solving similar problems
Mental sets
persistence in using strategies that worked in the past
Functional Fixedness
Think of an object as only functioning in its usual way
(Think of the example of tying string w/ the tools + The matchbox, candle, and screws
Confirmation Bias
Preffeting information that confirms preexisting positions of beliefs, while ignoring contradictory evidence
(the rooster raises the sun when he crows)
Heuristics
Rule of thumb (a mental shortcut)
saves time and effort
Can be useful but can bias our thinking
- anchoring
- availability
- representativeness
Anchoring Heuristics
The initial response sets the stage for subsequent judgments
(It will be used as a reference point, even if it is obviously wrong; they are long-lived and hard to set aside to think differently)
(ex: $600 for a couch, but when we see the context that it USED to be $1080, we think it is a deal)
Availability Heuristic
Judging the likelihood (frequency) of an event based on how readily available other instances are in memory
(Think about how we hear more stories on homicides vs cars running red lights. Homicides are much less likely to happen but we are more likely to hear about them. Same thing for hearing about the few that win the lottery but not the millions that lose it all the time)
Gamblers Fallacy
occurs when an individual erroneously believes that a certain random event is less likely or more likely to happen based on the outcome of a previous event or series of events
(I’m owed a win after losing the coin toss 25 times. The coin doesn’t think so)
Representativeness Heuristic
Estimating the probability of something based on how well the circumstances match (or represent) a previous prototype
(similarity + homogeneity; “like goes with like”; gamblers fallacy)
Loss Aversion
Tendency to be more sensitive to losses vs wins
Dunning-Kruger Effect
Overconfidence due to limited knowledge or competence
(Be curious, stay humble)
Sunk Cost Fallacy
Tendency to stick to a decision we’ve invested time, money, and or energy even if the current costs outweigh the benefits
Fundementla Attriubution Error
“They are sad today.. they’ll be sad tomorrow”
Binet
Developed a set of intellectual tasks that became the model for the current intelligence test
- Children’s mental abilities increase with age
Stanford-Binet Test
Developed by Terman
IQ test
IQ test
Intelligence Quotient
(mental age / chronological age) * 100
Stanford-Binet Test Tasks (Age 2)
Place geometric shapes to corresponding openings; Identify body parts; stack blocks; Identify common objects
Stanford-Binet Test Tasks (Age 4)
Name objects from memory; complete analogies; identify objects of similar shape; answer simple questions
Stanford-Binet Test Tasks (Age 6)
Define simple words; explain differences; Identify missing parts of a picture; count out objects
Stanford-Binet Test Tasks (Age 8)
Answer questions about a simple story; identify absurdities; Explain similarities and differences among objects; tell how to handle certain situations
Stanford-Binet Test Tasks (Age 10)
define more difficult words; give explanations; list as many words as possible; repeat 6-digit numbers
Stanford-Binet Test Tasks (Age 12)
Identify more difficult verbal and pictured absurdities; repeat 5-digit numbers in reverse; define abstract words; fill in a missing word in a sentence
Stanford-Binet Test Tasks (Age 14)
Solve reasoning problems; identify relationships among points of the compass; find similarities in apparently opposite concepts; predict the number of holes that will appear when folded paper is cut and then opened
Stanford-Binet Test Tasks (Adult)
supply several missing words for incomplete sentences; repeat 6-digit numbers in reverse order; create a sentence using several unrelated words; describe similarities between concepts
Wecheslers Test
Picture completion based on EXPERIENCES + seniorious
3 Standards for Psychological Tests
Standardization
reliability == consistency
validity == accuracy
Standardization in Psychological Tests
Establishes norms and uniform procedures for giving and scoring tests
Reliability == Consistency in Psychological Tests
Measure of the consistency and stability of test scores over time
(Consistent results for teenagers + adults [+.85 to +.95])
Validity == Accuracy in Psychological Tests
The ability of a test to measure what it was designed to measure
(good at predicting success in school [+.50])
Intellectual Disability
IQ =
70 - 50 (mild)
49 - 35 (Moderate)
34 - 20 (severe)
Below 19 (profound)
Mental Giftedness
IQ = 135 & Above
What can cause differences in IQ scores?
Brain Differences
Genetic Differences
Environmental Differences
The Bell Curve
Hernstein and Murray
- “IQ is fixed!”
- 40% - 80% heritability of intelligence
Developed Ability
Hereditary + Environment are important & inseparable factors in intelligence development
Neuroplasticity
Neurons can re-organize and “rewire” themselves
(group scores do NOT describe individuals)
Race v. Environment
Evidence suggests that racial/ethnic differences in IQ could be caused by ENVIRONMENT (not genetics)
Poverty
Is related to inferior nutrition, health care, & schooling
Klineberg
Study of african americans born in southern, rural settings
(+ correlation between IQ scores & time spent in a northern urban environment)
Gordon
Measured IQ among a canal-boat culture of England
What is the single best predictor of IQ scores?
“Years of Schooling!”
