Term
Declarative Memory
Definition
(knowing that) memories which can be consciously recalled such as facts and events
Term
Semantic Memory
Definition
factual information
Term
episodic memory
Definition
specific personal experiences
Term
Procedural Memory
Definition
(knowing how) memory for how to do things. resides below the level of conscious awareness. long-term implicit memory
Term
retroactive interference
Definition
newly learned information interferes with and impedes the recall of previously learned information
Term
Proactive interference
Definition
past memories inhibit an individuals full potential to retain new memories
Term
interference theory
Definition
stored memory is intact but unable to be retreived due to compitition created by newly acquired information
Term
method of loci
Definition
memorize information by walking around a garden or building in the minds eye and placing cues around the space
Term
retrograde memory loss
Definition
memory loss due to traumatic injury
Term
Ribot's Law
Definition
memories closest to the traumatic incident are more likely to be forgotten then more remote memories
Term
"Fan Effect"
Definition
participants were taught a new fact about a well known historical figure. later experimenters would describe an actual fact, a new fact or a false fact. they measured the time it took for the participant to identify if the fact was true or false.  the time it took to identify as true or false increased with the number of new facts learned-> new facts create competition
Term
Three levels of Human cognition
Definition

1) subjective experience of our own minds

2) the computaitional or functional analysis of mental representations and processes (regardless to ther relations to consciosuness) 

3) the neural substrate [underlying elements] of these

Term
why NOT introspective reports
Definition

1) of little use in analyzing how we preform practiced skills 

2) provide at best partical/ at worst misleading info about 

Term
alphabetic
Definition

graphemes represent phonemes (not always transparently) 

ex. greek, english, hebrew, arabic

Term
syllabic
Definition

graphemes represent syllables 

ex. japanese kana, korean, mongolian 

Term
ideographic/ logographic
Definition

graphemes represent meaning units

ex. japanese kanji, chinese 

Term
eye tracking
Definition
where, when and how long the eyes fixate during reading
Term
serial search model
Definition
Term
parallel comparison model
Definition
Term
computational model
Definition
simulated by a computer -> enforce precision and enables prediction
Term
dual- route model
Definition
Term
three modern views
Definition

1) feature theories- no one feature is needed only a sufficient combination 

2) computing resemblance of object to a prototype 

3) instance theories: resemblance of new objects to previously experienced instances 

 

Term
prototype theory
Definition
categorize the (previously unseen) prototype faster than previously seen instances and stands the passage of time better
Term
free recall
Definition
having a distracting tasks between learning list and recall
Term
Flashbulb memories
Definition
vivid memories of emotionally salient events
Term
iconic memory
Definition
persistence of visual information beyond the stimulus (<1 second)
Term
retro-active interference
Definition
recall strongly dependent on the amount of similar information encoded
Term
major reasons for forgetting
Definition
1) failure initially to encode the information deeply or elaborately
2) disruption of process of consolidating the memory trace
3) associative interference at retrieval
4) mismatch between the context of encoding and retrieval
Term
depth processing
Definition
processing the meaning of information instead of just the surface form/features
Term
associative interference
Definition
learning a second response to the same cue was particularly productive of "retroactive interference"
Term
encoding specificity
Definition
state dependent learning. increase in recall when context is the same at acquisition and test
Term
false memories
Definition
'recall'/'recognise' events that one did not experience
Term
speech act
Definition
the intent behind what people say (ie to request info, to provide info, to insult, to complement, etc.)
Term
lexical ambiguity
Definition
many spoken/ written words have more then one dictionary meaning so one must decide which is intended (ie. bank, right)
Term
exhaustive access
Definition
retrieve all meanings for each word and see what fits best with the meanings of the previous words
Term
selective access
Definition
retrieve only the meanings most related to prior context and try another if it doesn't fit
Term
semantic priming effect
Definition
Term
syntactic ambiguity
Definition
ambiguous sentence structure
Term
deductive reasoning
Definition
solving logical or mathematical problems when there is a right answer
Term
inductive reasoning
Definition
making probabilistic/ statistical generalizations predictions or inferring general rules from available data (ie. experience)
Term
problem solving
Definition
how to get from start to end goal via intermediate states, in states where there maybe many ways to get to the goal but some ways are better than others (ie tower of hanoi)
Term
heuristic
Definition
specialized for a specific kind of inferencing important to our evolutionary history, casual inferencing about physical and biological environment and detecting violations of social rules
Term
availability heuristic
Definition
estimation of frequency baed on experience- estimates are contaminated b/c of factors other than frequency (ie. R and K as first or third letter)
Term
representative heuristic
Definition
people judge the probability/ frequency of a hypothesis by concidering how much the hypothesis resembles available data as opposed to calculations (ex. laid back, long hair= cali)
assume similarity in one area leads to similarities in other aspects
Term
mental model
Definition
imagined concrete examples
- conform to the premises and get to conclusions by testing against the model
-may not capture the full range of possibilities
Term
dichotic listening
Definition
having two streams of different sounds pled one in each ear
Term
focused attention
Definition
pay attention to all but one source of stimulus
Term
divided attention
Definition
attempt to pay attention to multiple stimuli (poor comprehension)
Term
spotlight
Definition
anticipate a stimulus and focus our attention there
Term
working memory
Definition
mechanism for holding in mind, in an active , highly available state a small amount of information
Term
sensory memory
Definition
ability to retain sensory information after the original stimulus has ended
Term
long term memory
Definition
a system for permanently storing, managing and retrieving information for later use. items may be available for a lifetime
Term
recency effect
Definition
it is easier to remember more recent information then older information
Term
dual trace theory
Definition
retrieval after a short interval mediated by temporary rapidly decaying trace; retrieval after longer interval mediated by a more permanent trace
Term
single trace theory
Definition
trace decays rapidly to start with, then more slowly
Term
double dissociation
Definition
Term
retention
Definition
Term
phonological buffer
Definition
Term
neuropsychological dissociations
Definition
Term
amnesic syndrome
Definition
normal working memory but little or no ability to commit new facts/events to permanent memory
Term
iconic
Definition
memory for images
Term
echoic
Definition
memory for sounds
Term
attended words
Definition
identified and represented in a limited capacity short term store
Term
proactive interference
Definition
previously learned information prevents the acquisition of new information
Term
source amnesia
Definition
retrieval of information coupled with the inability to remember its source
Term
reconstructive memory
Definition
fragments of actual experience recovered from memory get combined with other information in memory whose source is lost
Term
extralinguistic cues
Definition
body language, eye movement, etc
