Q

encoding specificity principle

A

the idea that a retrieval cue can be an effective reminder when it helps recreate the specific way in which info was initially encoded

25
state dependent retrieval
the process whereby info tends to be better recalled when the person is in the same state during encoding and retrieval
26
transfer appropriate processing
the idea that memory is likely to transfer from 1 situation to another when the encoding and retrieval contexts of the situations match
27
retrieval induced forgetting
a process by which retrieving an item from long term memory impairs subsequent recall of related items
28
explicit memory
the act of consciously or intentionally retrieving past experiences.
29
implicit memory
the influence of past experiences on later behavior and performance even without an effort to remember them or an awareness of the recollection
30
procedural memory
the gradual acquisition of skills as a result of practice, or "knowing how" to do things
31
priming
an enhanced ability to think of a stimulus, such as a word or object, as a result of recent exposure to that stimulus during an earlier study task
32
semantic memory
a network of associated facts and concepts that make up our general knowledge of the world
33
episodic memory
the collection of past personal experiences that occurred at a particular time and place
34
transience
forgetting what occurs with the passage of time
35
retroactive interference
interference with retention of old info due to acquisition of new info
36
proactive interference
interference with acquisition of new info due to previous learning of info
37
absentmindedness
a lapse in attention that results in memory failure
38
prospective memory
remembering to do things in the future
39
blocking
a failure to retrieve info that is available in memory even though you are trying to produce it
40
source memory
recall of when, where, and how info was acquired
41
false recognition
a feeling of familiarity about something that hasn't been encountered before
42
suggestibility
the tendency to incorporate misleading info from external sources into personal experiences
43
bias
the distorting influences of present knowledge, beliefs, and feelings on recollection of previous experiences.
44
persistence
the intrusive recollection of events that we wish we could forget
45
flashbulb memories
detailed recollections of when and where we heard about shocking events
46
memory illusion
false but subjectively compelling memory
47
retention interval
a period during which the learning or practice pf a behavior does not occur
48
interference
loss of info from memory because of competition from additional incoming info
49
decay
fading of info from memory over time
50
magic number
the assumed span of short term memory ; 7 + or - pieces of new info
51
maintenance rehearsal
repeating stimuli in their original form to retain them in short term memory
52
elaborative rehearsal
linking stimuli to each other in a meaningful way to improve retention of info in shorty term memory
53
levels of processing/ depth processing
a model of memory that posits the more deeply we process info, the better we are at remembering it ( transferring it to LTM). has 3 levels; structural ( visual), phonological (auditory), semantic (its meaning).
54
permastore
type of long term memory that appears to be permanent
55
primacy effect
tendency to remember words at the beginning of a list especially well. traditionally thought to reflect LTM processes
56
recency effect
tendency to remember words at the end of a list especially well. traditionally thought to reflect STM processes.
57
repeated retrieval
repeatedly trying to recall/ use material over time. i.e. quizzing yourself
58
semantic priming
semantically relating words will result in faster reaction times
59
memory as a network of associations
theory that memory can be represented as a network of associated concepts. each concept is represented by a node, and lines between each node represent associations.
60
engram
hypothesized, physical trace of a memory with in the brain. Karl Lashley, trained rats in a maze. lesioned brain areas
61
Hebbian learning
Donald Hebb. hypothesized that when axon of cell 1 is close enough to excite cell 2 and does this continuously, some growth process/ metabolic change takes place in one or both cells. such that cell 1's efficiency is increased
62
Alzheimer's disease
degenerative brain disease that results in dementia. language and other body processes deteriorate. strong genetic component associated with neurological abnormalities like deterioration of acetylcholine neurons in cortex
63
infantile amnesia
inability of adults to remember personal experiences that took place before an early age . occurs for events before 2-3. may be due to underdeveloped hippocampus
64
crypto amnesia
failure to recognize that our ideas originates with someone else. may be result of source monitoring confusion/ lack of clarity of origin of memory
65
misinformation effect
creation of fictitious memories by providing misleading info about an event after it takes place
