Thinking and Language (Ch 9), Intelligence (Ch 10), & Personality (Ch 13) Flashcards
prototype
a mental image or best example of a category. matching new items to the prototype provides a quick and easy method for including items in a category (as when omparing feathered creatures to a prototypical bird, such as a robin)
-categories have fuzzy boundaries as we move away from our prototypes. is a tomoato a fruit?
we more quickly agree a “Robin is a bird” than a “goose is a bird”, because a robin more closely fits the bird prototype
algorithm
a methodical, logical rule or procedure that guarantees solving a particular problem
-contrasts w/ the usually speedier - but also more error-prone - use of heuristics
-searching every supermarket aisle to find guave juice, rather than checking the bottled jiuce section ( a heuristic)
Insight
a sudden and often novel realization of the solution to a problem
- it contrasts w/ strategy-based solutions
- provides sense of satisfaction (figuring out a joke)
- burst of activity in right temporal lobe associated w/ insight

confirmation bias
a tendency to search for information that confirms one’s preconceptions
business managers are more likely to follow the successfuly careers of those they once hired than to “track the acheivements of those tey rejected”
An atheist may Google “Proof God doesn’t exist”
a theist may Google “Proof God does exist”
fixation
the inability to see a problem foom a new perspective
an impediment to problem solving
connecting 3x3 grid of dots with 4 connecting lines.
“staying inside of the box”
functional fixedness
a tendency to think of things only in terms of their usual functions; an impediment to problem solving
a person may ransack the house for a screwdriver when a dime would have turned the screw
representativeness heuristic
judging the likelihood of things in terms of how well they seem to represent, or match. particular prototyes may lead one to ignore other relevant information
-identifiend by Amos Tvrsky and Daniel Kahneman
a person is short, slim, and likes to read poetry. Is the person morelikely to be a professor of classics at an Ivy Leagu or a truck driver (representativeness heuristic would lead to false answer: “Ivy professor”)
Framing
the way an issue is posed
- how an issue is framed can significantly affect decisions and judgements
- those who understand the power of framing can use it to influence our decisions
90% of college students rate a condom as effective if it has a supposed 95% success rate” in stopping HIV spread where as 40% rate it effective if told it has a 5% failure rate
Phoneme
in language, the smallest distinctive sound unit
to say “bat” we say b,a,t
to say “chat” we say ch, a, t
morpheme
- in language the smallest unit that carries meaning
- maybe a word or a part of a word (such as a prefix or suffix)
1 morpheme: I; a; bat
2 morphemes: pre-view; bat-ted
syntax
the rules for combining words into grammatically sensible sentences in a given language
ex: one rule of English syntax says that adjectives usually come before nouns, so we say “white house”
The english rules of syntax allow hte sentence “They are hunting dogs” given the context, semantics will tell us whether it refers to dogs that seek animlas or people who seek dogs
telegraphic speech
early speech stage in which a child speaks like a telegram - “go car” - using mostly nouns and verbs
-the type of speech babies use in their two-word stage, which babies reach when they turn two
Whorf’s Linguistic determinism/ Linguistic Relativity
Whorf’s hypothesis that language determines the way we think
English has a rich vocabulary for self-focused emotions such as anger
- Jaganese has more words for interpersonal emotions such as sympathy
- many bilinguals report they have different senses of self depending on the language they are using
Critical period (for language)
there is a window for learning a language based on age

convergent thinking
- the type of thinking that demands a single correct answer
- intelligence tests measure convergent thinking
- convergent and divergent thinking engage different areas of the brain
“what is 27 x 84”
divergent thinking
creative thinking
injury to certain areas of the frontal lobes can leave reading, writing, and arithmetic skills intact, but destroy imagination
“How many uses can you htink of for a brick?”
language acquisition device
- a “switch box”
- helps us learn language
- part of Chomsky’s Inbon universal Grammar Theory
- Given adequate nurture, language will naturally occur. It just “happens to the child”.
- it as if the switches need to be turned either “on” or “off “ for us to understand and produce language. As we hear languages, the switches get set for the language we are to learn
Broca’s area
- controls language expression - an earea of the frontal lobe usually in the left hemisphere, that directs muscle movements invovled in speech
- controls speech muscles via the motor cortex
- after damage to the Broca’s area, person would struggle to speak words while still being able to sing familiar songs and comprehends speech
someone who broke their Broca’s area would have trouble saying that.
Was that example in my damage to the Wenicke’s area card actually wernickes area???
Belief Perserverance
clinging to one’s initial conceptions after the basis on which they were formed has been discredited
-once beliefs form and get justified it takes more compelling evidence to chang them thatn it did to create them
-once people have explained to htemselves why company Z is a stock worht owning, htey tend to ignore the evidence that undermines the belief
Availability Heuristic
estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common
Because words beginning with k come to mind more easily than words having k as their third letter, most people falsely guess that k appears more frequently as the first letter
overconfidence
the tendency to be more confident than correct - to evrestimate the accuracy of one’s beliefs and judgements
- people who err on the side of overconfidence live more happily, find it easier to make tough decisions, and seem more credible
- if given prompt and clear feedback on the accuracy of their judgements people soon learn to asses their accuracy more realisitically
-presuming how much we’re going to get done, we overestimate our future free time
Noam Chomsky
- linguist
- Inborn Universal Grammar + thought Skinner’s ideas were naive and over simplified
Language will naturally occur, given adaquete nurture, it just happens to hte child
we are born with the OS/hardware for languge, and our linguistic experiences write the software.
Deaf children community where they created a language w/ complex grammar
Receptive language
- the ability for babise to comprehend speech
- segmenting spoken sounds into individual words
- adeptness at this task, as judged by their listening pattern, predicts their language abilities at ages 2 and 5
-the development of this begins when babies prefer to look at a face that matches a osund, so that we can recognize that “ah” comes from wide open lips and “ce” from a mouth with corners pulled back
grammar -
a system of rules that enable us to communicate with and understand others; grammar = semantic + synatx
semantics
the set of rules by which we derive maening from morphemes, words, and sentecnes in given language; also, the study of meaning
ex: a semantic rule - adding “ed” to laugh means it happened in the past
syntax
the rules for combining words into grammatically sensible sentences in a given language
ex: adjectives usually come before nouns
Wechsler Adult Intelligence Scale
- most widely used intelligence test
- contains verbal and performance (nonverbal) subtest
- overall intelligence score, verbal comprehension, perceptual organization, working memory, and processing speed
- WISC - for children, and one for preschool
“Wais your IQ, man?”
Standardization
defining meaningful scores by comparison with the perfomance of a pretested group
-to be widely accepted, psychological tests must be sandardized, reliable, and valid.
Normal curve
the symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes
Flynn effect
- intelligence test scores have been rising since 1920s
- in 20 countries
- from test sophistication? better nutrition? better education? more parental investment?
- recently the trend may be leveling off
img
reliability
- the extent to which a test yelds consistent results, as assessed by consistency of scores on two halves of the test, or on retesting
- to test reliability, researchers retest people
