Term
memory store
Definition
a set of neurons that serves to retain info over time
Term
sensory memory
Definition
a memory store that holds a large amount of perceptual info for avery brief time, typically less than 1 second
Term
short term memory
Definition
a memory store that holds relatively little info for only a few seconds also called immediate memory
Term
chunk
Definition
an organized unit of info such as a digit letter or word
Term
central executive
Definition
set of processes in wm that transforms and interprets info in one or another of two specialized stms during planning, reasoning, and problem solving
Term
working memory
Definition
the memory system that includes two specialized stms and a central executive that operates on info in the stms to plan reason or solve a problem
Term
long term memory
Definition
a memory store that holds a huge amount of info for a long time
Term
primacy effect
Definition
increased memory for the first few stimuli in a set, reflecting storage of info in ltm
Term
recency effect
Definition
increased memory for the last few stimuli in a set, reflecting storage of info in stm
Term
consolidation
Definition
the process of converting info stored dynamicaly in ltm into a structual change in the brain
Term
depth of processing
Definition
the number and complexity of the mental operation used when processing; deeper processing occurs when more-- or more complex-- operations are used during encoding
Term
transfer appropraite processing
Definition
processing used to retrieve material that is the same type as was used when the material was orginally studied, which improves memory retrieval
Term
breadth of processing
Definition
processing that organizes and integrates new info into previously stored info often by making associations
Term
intentional learning
Definition
learning that occurs as a result of tring to learn
Term
incidental learning
Definition
learning that occurs without the intention of learning
Term
flashbulb memory
Definition
an unusually vivid and detailed memory of a dramatic event
Term
articulatory loop
Definition
type of stm that holds articulatory sounds  like a continuous play tape recorder, need to rehearse repeatedly to continue to store sounds in the loop
Term
visuospatial sketch
Definition
different type of stm that holds visual and spatial info. like a notepad with patterns drawn in fading ink, briefly retains mental images of the location of objects
Term
implicit memory
Definition
cannot be voluntarily called to mind, but influence behavior or thinking
Term
explicit memory
Definition
can be retrieved at will and represented in stm as words or images
Term
semantic memory
Definition
memories of the meanings of words, concepts and facts
Term
episodic memory
Definition
memories of events associated witha particular time place and circumstance
Term
long term potentiation
Definition
the strengthening of the connections between the sending and receiving neurons that underlies memory storage
Term
language production
Definition
the ability to speak or otherwise use words phrases and sentences to convey info
Term
generative
Definition
creation and generation of new sentences; dont simply retrieve and repeat stored sentences
Term
phonemes
Definition
basic building blocks of speech sounds
Term
aphasia
Definition
a dsiruption of language due to brain damage
Term
broca's aphasia
Definition
problems with producing language following brain damage to the left frontal lobe
Term
wernicke's aphasia
Definition
problems with comprehending language following brain damage typically to the left posterior temporal lobe
Term
semantics
Definition
the meaning of a word or sentence
Term
morphemes
Definition
smallest units of meaning in a language
Term
propositional representations
Definition
mental sentences that represent the unambiguous meaning of assertions
Term
pragmatics
Definition
the way that language conveys meaning indirectly, by implying rather than asserting
Term
overextension
Definition
an overly broad use of a word to refer to a new object or situation
Term
underextension
Definition
an overly narrow use of a word to refer to a new object or situation
Term
biological basis
Definition
the readiness for language development as a normal phase of development, and or a gene or sets of gene responsible for language
Term
critical period
Definition
a narrow window of time when a certain type of learning is possible
Term
algorithm
Definition
set of steps guaranteed to reach a solution
Term
heuristic
Definition
rule of thumb that may offer a shortcut but is not guaranteed to reach a solution
Term
insight
Definition
a new way to look at a problem that implies the solution
Term
incubation
Definition
processing that occurs when a person is not consciously working on solving a problem and that can lead to improved thinking about the solution
Term
cognitive control
Definition
the processes that guide attention, thought, and action in the service of accomplishing a specific task
Term
logic
Definition
the process of applying the principles of correct reasoning to reach a decision or evaluate the truth of a claim
Term
deductive reasoning
Definition
applies the rules of logic to a set of assumptions to discover whether certain conclusions follow from those assumptions
Term
mental models
Definition
an image of a specific situation used to reason about an abstract entity
Term
inductive reasoning
Definition
uses examples to figure out a rule that governs them
Term
confirmation bias
Definition
a tendency to seek only information that will confirm a rule
Term
representativeness heuristic
Definition
the more similar something is to a prototype stored in memory, the more likely it is to belong to that category
Term
availability heuristic
Definition
the easier event or objects are brought to mind, the more likely, common, or frequent they are judged to be
Term
emotion
Definition
a positive or negative reaction to a perceived or remembered object, event, or circumstance, accompanied by a subjective feeling
Term
social learning
Definition
even with "basic" emotions, the contribution of the genes which produce inborn tendencies connot be considered in isolation from events at the levels of the person (such as learning) and group (such as whether one is a member of a specific race and culture)
Term
evolutionary psychology
Definition
hardwired goals survival of the fittesets, skills that are available to the specimens that pass on their genes
