Q

differences between automatic and effortful processing

A

effortful processing is usually disrupted when a person has to pay attention to other stimuli

Q

memory span

A

maximum number of items that can be recalled in the correct order

25
chunking
grouping bits of information together to increase ability to remember "1980 03 12" instead of "19800312"
26
explicit memory
memories that you can consciously bring to mind ex. your middle name
27
implicit memory
memory that a person is not consciously aware of (skills, habits etc.)
28
explicit memory categories
1. semantic memory= facts and knowledge 2. episodic memory= personal experiences
29
implicit memory categories
1. procedural memory (motor skills and habits such as riding a bike) 2. classically conditioned memory (ex. conditioned responses to stimuli such as phobias) 3. priming= activated memories based on previous events (ex. heightened fear after watching a horror movie)
30
retrieval cues
words, sights or other stimuli that remind us of information we need to retrieve from our memory
31
priming
activating one piece of information, which then leads to the activation of another piece, and then the activation of a memory
32
recognition tasks
memory tasks in which people are asked to identify if that have or have not seen a particular item before
33
recall tasks
memory tasks in which people are asked to produce information using little/no retrieval cues
34
context effecct
the original location where you first learned a concept or idea, rich with retrieval cues that will make it more likely you will be able to recall that information later if you are in that same location or context ex. lists learned underwater were best recalled underwater, and that lists learned on land were best retrieved on land
35
encoding specificity principle
memory retrieval is more efficient when the information available at retrieval is similar to the information available at the time of encoding
36
state-dependent memory
memory retrieval facilitated by being in the same state of mind in which you encoded the memory in the first place
37
flashbulb memories
tailed and near-permanent memories of an emotionally significant event, or of the circumstances surrounding the moment we learned about the event ex. during 9/11 most people could remember where they were
38
decay theory
theory of forgetting, suggesting that memories fade over time due to neglect or failure to access over long periods of time
39
interference theory
theory that forgetting is influenced by what happens to people before or after they take information in -retroactive -proactive
40
retroactive interference (backward acting)
new info interferes with old info ex. every time you learn a new fish name you forget the name of a student in class
41
proactive interference (forward acting)
old info interferes w new info ex. refer to new boyfriend using old boyfriend's name
42
interference only occurs when information
conflicts
43
repression
process in which we unconsciously prevent some traumatic events from entering our awareness so that we do not have to experience the anxiety or blows to our self-concept that the memories would bring
44
source misattribution
remembering information, but not the source it came from; can lead to remembering information from unreliable sources as true
45
prefrontal cortex
brain structure located just behind the forehead and implicated in working memory
46
hippocampus
converts explicit memories into long term memory
47
memory consolidation
process by which memories stabilize in the brain
48
potentiation
synchronous networks of cells firing together
49
long-term potentiation (LTP)
a phenomenon where repeated stimulation of certain nerve cells in the brain greatly increases the likelihood that the cells will respond strongly to future stimulation
50
prospective memory
ability to remember content in the future
51
retrospective memory
ability to remember content from the past
52
amnestic disorders
organic disorders in which memory loss is the primary symptom
53
retrograde amnesia
inability to remember things that occurred before an organic event
54
anterograde amnesia
ongoing inability to form new memories after an amnesia-inducing event
55
dementia
severe memory problems combined with losses in at least one other cognitive function, such as abstract thinking or language
56
Alzheimer’s disease
most common form of dementia, usually beginning with mild memory problems, lapses of attention, and problems in language, and progressing to difficulty with even simple tasks and recall of long-held memories
57
neurofibrillary tangles
twisted protein fibres found within the cells of the hippocampus and certain other brain areas
58
senile plaques
sphere-shaped deposits of a protein known as beta-amyloid that form in the spaces between cells in the hippocampus, cerebral cortex, and certain other brain regions, as well as in some nearby blood vessels
59
transfer/context dependent processing
memory transfers from one situation to another when the context of the encoding situations match
