What are concepts?
Mental representations of a category
Aspects of _____ memory allow us to categorize stimuli we have already encountered
Semantic (general world knowledge we have accumulated)
Downsides of concepts are “_____”
stereotypes
One way we learn concepts: ______ strategy - responding to all attributes of a conceptual class or category
wholist strategy
One way we learn concepts: ____ strategy - focusing on a single attribute of a conceptual class or category
partist strategy
_____- hypothesis testing about a concept by making guesses about which attributes are essential for defining the concept
concept learning
Categorize novel stimuli, fast and efficient understanding, inferences of knowledge not explicitly stated, relationship to language? - _____ of concepts
functions of concepts
____ - concepts in which members must posses both of two separate attributes
conjunctive concepts
_____- concepts in which members must posses either one of two separate attributes
disjunctive concepts
Members of a concept share in common - _____ resemblances; for example birds
family
____ level: the most generic and inclusive of conceptual category: for example a plant
superordinate level
____ level: the most useful level of a concept, characterized by neither too much not too little information: for example a tree
basic level
___ level: the most restrictive, specific level of conceptual category: for example a palm tree
subordinate level
___ view - where people create and use categories based on a system of rules; necessary and sufficient features
classical view
What are the two theories that make up ‘probabilistic approaches’
Prototype theory and exemplar theory
_____ theory - people abstract the common elements of a particular concept and then store abstracted prototypical representation in memory
prototype theory
The pros of ______: No set rules, generability - account for individual differences - fast decisions
the prototype theory
The cons of ____: hard to explain categories when individuals are very different
prototype theory
______- people take into account each encounter that they experienced w the members of that category; based on similarity among members and comparison to standards
exemplar theory
What are the pros of exemplar theory?
very good at explaining broad concepts
what are the cons of exemplar theory
need a lot of time to describe a concept
what are semantic networks?
Structure for how info is stored in long term memory, semantic memory specifically. Concepts are nodes and connected by links and pathways. Activation of pathways spread from one concept to another
The strength activation of nodes, which are concepts in the semantic network, depend on what?
Time, distance, and # of concepts activated
___- when concepts are activated in memory, activation spreads to semantic related concepts, making them easier to fully activate if needed
semantic priming
What are the four types of categories?
natural, artifact, ad hoc, and metaphorical
What are natural categories?
Occur naturally in the world, members of category share characteristics and features - plants
What are artifact categories?
Objects designed or invested by humans to serve particular functions - bowls and plates
What are ad hoc categories
Formed to meet a special demand - what to pack on vacation
What are metaphorical category
Category where there is a common underlying “theme” that unites members of category - things that are a “waste of time”
____- natural and essential characteristics that are inherited, innate, and unchanging
essentialist approach
_____ - highly structure symbol that allows for creative and meaningful communication
language
_____- discipline devoted to understanding the properties of human language and the mechanisms responsible for language acquisition
psycholinguistics
____- all the words (symbols) that allow for communication and comprehension - dimension of semantic memory - each representation include more than the meaning like the sound, written form
mental lexical
____ - process by which an individual produces a specific word from his or hers mental lexical or recognizes when used by others
lexical access
____- elements of a language that convey meaning
semanticity
___- the connections bt linguistic units and concepts or meanings are not predictable
arbitrariness
____- language allows us to talk about times other the immediate present
displacement
_____- the ability that language allows us for misrepresentation and deception
prevarication
_____- the ability that language allows to reflect on language itself
reflectiveness
____ - an infinite # of sequences can be produced by applying the rules of language
productivity
______ - features and characteristics that universally true of all human languages - universals are used to distinguish human language from animal communication
linguistic universal
_____- made up of phonology, pragmatics, morphology, semantics and syntax (think of diagram)
levels of analyses
_____ - analyses of the sounds of language as they are articulated and comprehended in speech
phonology
What are phonemes?
basic sounds that compose a language
_____- involves continuous flow of air through the vocal tract
vowel phonemes
