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
