Psychology Chapter 7- Cognition
creativity
combining ideas and behaviors into new ways of doing things
availability heuristic
estimation of likelihood based on memorized examples
natural concepts
formed not as a result of a set of rules, but from real-world experiences
cognitive processing
includes concepts, prototypes, and mental images to identify objects
trial-and-error
mechanical solution through attempting to do something and seeing what works and what doesn't
thinking/cognition
mental activity that goes on in the brain when a person is processing information
Grammar includes _________ and __________.
phonemes and morphemes
confirmation bias
searching for evidence that fits one's beliefs while ignoring any evidence that doesn't support them
language
system for combining symbols so that an infinite number of meaningful statements can be made for the purpose of communicating with others
validity
the degree to which a test measures its intention
Name 3 of Gardner's multiple intelligences
verbal/linguistic, intrapersonal, visual/spacial, musical
intonation
what rhythm and emphasis to use when communicating
Can sentences have the same meaning but different syntax?
yes
morphemes
-smallest units of meaning in language -ex: playing = "play" and "ing"
heuristic
"rule of thumb" simple rule that almost always applies
standard deviation
average variation of scores from the mean
subgoals
breaking tasks into steps to make them seem less overwhelming
formal concepts
has rules and criteria
What are some divergent thinking techniques?
1. brainstorming 2. keeping a journal 3. freewriting 4. mind or subject mapping
Jean Piaget
believed that concepts become pegs for words (concepts come before language)
concepts
ideas that represent a class or category of objects, events, or activities
convergent thinking
logical problem-solving method -STICK TO THE STUFF YOU KNOWWW
ecological validity
measures if an IQ test's score reflects what it's supposed to
pragmatics
practical aspects of communicating with others such as how to take turns in a conversation and use of gestures
standardization
process of giving tests to a large group that represents the right demographic
semantics
rules for determining the meaning of words and sentences
linguistic relativity hypothesis
says that language shapes and influences thoughts -thought processes and concepts within culture are determined by words
Can animals use language?
scientists can agree that animals are capable of communication, but it is highly disputed if they are technically capable of language -all trained animals have only reached 2-year-old level of language ability, requirement is 3
norms
scores from standardization group
alogrithms
step-by-step procedures (mathematical formulas)
syntax
system of rules for combining words and phrases to form grammatically correct sentences
grammar
system of rules governing the structure and use of language
cultural bias
tendency of IQ tests to reflect in language, dialect, and content, the culture of the test designer (Adrian Dove = studied culturally fair tests)
intelligence
the ability to learn from one's experiences, aquire knowledge, and use resources effectively in adapting to new situations or solving problems
cognitive universalism
concepts are universal and influence development of language
phonemes
-basic units of sound in language -ex: the "a" in "car" vs "day"
Name 3 popular IQ tests.
1. Binet's Mental Activity Test 2. Stanford-Binet IQ 3. Wechleser Test
What are the different theories of intelligence?
1. Spearman's theory = g factor, general intelligence, s factor, specific intelligence 2. Gardner's multiple intelligences = you can excel at many things 3. Sternberg's triachtic theory
Sternberg's triachtic theory
1. analytical: break problems down for analysis 2. creative: new ways of solving problems 3. practical: street smarts, use information to increase success
What is diagnosis of intellectual disability based on?
1. deficits in intellectual functioning determined by standardized tests across 3 domains a. conceptual (memory, reasoning, language, reading, math) b. social (empathy, social judgement, interpersonal) c. practical (self-management skills including personal care)
What are the symptoms of intellectual disability?
1. person exhibits deficits in mental abilities (IQ score 2 standard deviations below average, score<70) 2. adaptive behavior (skills for independence) is severely low for person's age -symptoms must begin in developmental period -happens in 1% population
What are the different ways to solve problems?
1. trial-and-error 2. algorithms 3. heuristic
What are the causes of intellectual disability?
1. unhealthy living conditions that can affect brain development such as lead poisoning, PCB exposure, prenatural mercury, and other toxicants 2. can be associated with the malnourishment and poor living conditions of poverty 3. down syndrome, fetal alcohol syndrome, fragile X syndrome 4. lack of oxygen at birth, fetal womb disease, infections, drug use, accident diseases
What IQ range is considered to be gifted?
130 and above, 2% of the population
What IQ range is considered to be genius?
140-145
Binet's Mental Activity Test
Alfred Binet made the test to identify children that couldn't learn so they can get remedial education
Who shattered the "nutty genius" belief?
Lewis M. Terman, who also developed the Stanford-Binet test -proved that gifted children were less susceptible to mental disease, and that they were above normal height, weight, and attractiveness -called Terman's "termites"
Stanford-Binet IQ
Lewis Terman of Stanford adopted William Stern's method for comparing mental and chronological age
functional fixedness
a block to problem solving that comes from only thinking about using things for their normal functions
Who is Kanzi?
a bonobo chimpanzee that reached 2-year-old level of language
emotional intelligence
accurate awareness and ability to manage emotions and facilitate thinking -understanding what others feel -high emotional intelligence correlates with high general intelligence
stereotype threat
being aware of negative stereotypes and individually scoring poorly
Lev Vygotsky
believed that language helps develop concepts and behavior
Standardization of tests
bell curve
prototype
concept that closely matches defined characteristics
natural experiments
circumstances in nature that can be examined to explain some phenomenon
mental set
continuing to use problem-solving techniques that have worked before
divergent thinking
creative and different thinking
script
familiar sequence of activities
representativeness heuristic
groups common characteristics as part of the same category
schemas
mental generalizations about people, places, or things
Wechleser Test
more age-specific intelligence quotient
intellectual disability
neurodevelopmental disorder
heritablity
proportion of change in IQ within a population caused by hereditary factors
Hernstein and Murray
published the book "the bell curve" and failed to address culture, validity, and concepts of heritablity -heritability only applies to differences within a group, not between groups
insight
realizing a solution suddenly ("aha" moment)
mental images
representations that stand in for objects or events and have picture-like quality
Noam Chomsky
says humans can communicate because of LAD (language acquisition device) -LAD listens to language input of an infant's world and begins to produce language in a pattern found across cultures
reliability
test producing consistent results
intelligence quotient
test that measures intelligence
superordinate concepts
the most general forms of a type of concepts, such as "animal" or "fruit"
What are the different levels of diagnosis for intellectual disability?
varies from mild to profound (profound being the worst)
