Problem Solving and Intelligence Flashcards
Intelligence
the cognitive ability of an individual to learn from experience, reason well, remember important information, and cope with the demands of daily living
Assumptions for intelligence
involves ability to perform cognitive tasks, and capacity to learn from experience and adapt
Deductive reasoning
person works from ideas and general information to arrive at specific conclusions
Inductive
move from specific facts and observations to broader generalizations and theories
Functional fixedness
our difficulty seeing alternative uses for common objects
eg. candle problem
Reliability
measures the extent to which repeated testing produces consistent results
Validity
measures the extent to which a test is actually measuring what the researcher claims to be measuring
Francis Galton
performed a study on reaction time;
established the modern study of intelligence
Alfred Binet
produced first intelligence scale for children;
30 short tasks related to everyday life that were assumed to involve reasoning;
Lewis Terman further adapted the scale
Charles Spearman
single type of intelligence (g), which includes vocabulary, math, special abilities etc.;
advocated that only individuals with a certain “g” should be allowed to vote and reproduce
Howard Gardner
multiple intelligences = linguistic, mathematical, rhythmic, spatial, kinesthetic, interpersonal, intrapersonal, naturalistic;
each type of intelligence is independent from the others
Wechsler scales
standardized to produce an intelligence quotient for each individual;
scoring is based on results of large samples of individuals;
mean receives a score of 100;
standard deviation of 15
Identical and fraternal twins
identical = +0.8 correlation, fraternal = +0.6 correlation
identical raised in different environments = +0.73 correlation
Flynn effect
the observation that raw IQ scores have been on the rise; may be due to increase in quality of life
Assimilation
incorporation of new information into existing schemas
Accommodation
modifying existing schemas to fit incompatible information
Decalage
children sometimes develop some skills out of order of Piaget’s stages of development
Sensorimotor stage
(0-2)
begins to recognize that he can affect change on his environment;
object permanence = realization that objects continue to exist when no longer visible
Preoperational stage
(2-7) egocentric; difficulty with seriation tasks; difficulty with reversible relationships; struggle with conservation tasks
Concrete operational stage
7-12)
child’s schemas are still concrete and based on experiences with the world;
unable to think in abstract terms or reason based on hypotheses
Formal operational stage
(12+)
can do everything that makes up the range of adult cognitive abilities
Confirmation bias
our tendency to seek out information that supports our hypothesis;
testing a hypothesis involves seeking data that could both confirm and refute it
Availability bias
our tendency to make decisions based on the information that is most quickly available to us
Representativeness heuristic
tendency to assume that what we are seeing is representative of the larger category we have in our mind
Bounded rationality
cognitive limitations prevent humans from being fully rational
Rational vs emotional factors
rational = price, quality, feature, reliability, warranty; emotional = look, feel, esteem, brand, safety, fear
System 1
passively view web module, passively highlight textbook, take verbatim notes, memorize given examples for concepts
System 2
pause and review web module, self-test on textbook, summarize notes, create novel examples for concepts; leads to durable learning
Anchoring
the bias to be affected by an initial anchor, even if the anchor is arbitrary
Framing
the bias to be systematically affected by the way in which information is presented
Decision architecture
accounts for human bias to trigger higher participation rates;
people are more inclined to opt out vs. opt in
Fluid intelligence
reflects how well you tackle a new task rather than what facts you possess
Working memory
short term memory, keeps vital information at the ready;
key component in fluid intelligence
Prefrontal cortex
responsible for executive function;
regulates attention, modulates impulses and coordinates information coming from other brain centers
ADHD and fluid intelligence
developed a computer program to exercise working memory;
after 5 weeks, fluid intelligence was increased, lessening of symptoms
