Q

Rehearsal

A

Repeating information over and over again. This keeps the information “alive” as long as we keep repeating, but is ultimately uneffective for long term retrieval.

Q

Elaborative rehearsal

A

We elaborate on stimuli, applying meaning. This takes more mental effort and will likely stick better in our memories.

Three ways short-term and long term memories differ

A

25
Two types of Explicit Memory
Semantic, Episodic
26
Four types of Implicit Memory
Priming, Habituation, Procedural, Conditioning
27
Three processes of memory
encoding, storage, retrieval
28
Encoding
Process of getting information into our memory
29
Next-in-line effect
So focussed on what you were going to say that you weren't paying attention to the person in front of you and can't remember what they said
30
mnemonic
learning aid that enhances recall, often a phrase that uses the same letters as something that needs to be remembered "every good boy deserves fudge - EGBDF musical notes" or Roy G Biv for the rainbow
31
Pegword method
Type of mnemonic that uses rhyming.
32
Which type of memory has been demonstrated in 32 week fetuses?
Habituation
33
How best to remember all the letters in CARBEDDOGCATEATPIE?
Chunking
34
Mnemonics will be most helpful as encoding devices if we...
...practice them on a regular basis
35
What kind of memory is used for trivia
Semantic
36
Sensory memory has a larger _____ than short term, but smaller ______
Capacity, duration
37
Remembering an event that never actually occured demonstrates the role of ____ in producing false memories
Plausible events
38
Why do people generally find multiple choice questions easier than fill in the blank?
MC provides more retrieval cues for the correct answer
39
Bobby remembers important events but forgets where he puts his keys is an example of the...
paradox of memory
40
If you close your eyes, you can still "see" the last thing you looked at. This is known as...
iconic memory
41
Shannon is trying to take notes in and is able to write down what the professor just said due to her...
echoic memory
42
System of memory that is comprised of our immediate visual and auditory experience is known as...
sensory memory
43
If emotional reaction to memories is inhibitied, which area of the brain was likely damaged ?
Amygdala
44
When someone can remember something from 20 years ago, that information is...
in permastore
45
Harry Bahrick found that memory declined...
rapidly for about two years, then gradually after.
46
Hyperthymestic syndrome
When a person can recall every detail in great detail including the dates.
47
An important source of false memories comes from...
source monitoring confusion
48
Source monitoring confusion
lack of clarity about the origin of a memory
49
Tip of the tongue phenomenon
knowing you know something, but can't recall it.
50
Anterograde amnesia
inability to encode new explicit memories
51
Which drug has been used to blunt the negative emotional effects of traumatic experiences?
Propranolol
52
Propranolol
drug used to treat PTSD
53
Serial Position Curve
U-shaped learning curve that is normally ovtained while recalling a list of words due to greater accuracy of recall of words from the beginning and the end of the list than the middle of the list.
54
Storage
process of keeping information in memory
55
Schema
organized knowledge structure or mental model that we've stored in memory (frame of reference for interpreting new situations, ex script - restaurant ordering sequence)
56
Retrieval
Third process of memory, fetch it from long-term memory banks.
57
Retrieval cues
hints that make it easier for us to recall information
58
3 ways psychologists assess people's memory
Recall, recognition, relearning
59
Recall
Generating previously remembered information on our own.
60
Recognition
selecting previously remembered information from an array of options
61
Relearning
how much more quickly we learn information when we study something we've already studied relative to when we studied it the first time.
62
Ebbinghaus
Created the curve of forgetting
63
Curve of forgetting
created by Ebbinghaus, how much faster we forget things right away, and then how the forgetting slows down.
64
Percent savings
What percentage of learned information is remembered for how long, and how this affects how much faster relearned information sticks.
65
Why is relearning a more sensitive measure of memory than recall or recognition?
Because relearning offers a basis for comparison. (How much faster was the material learned the second time?)
66
What is another (other than relativity) advantage of measuring memory through relearning?
Rather than just right or wrong, we can use it to measure procedures like driving a car or playing piano.
67
Law of distributed vs massed practice
We remember things better when spread over long intervals (distributed) rather than packing it into short intervals (massed practice)( (ebbinghaus)
68
Encoding specificity
more likely to remember something when the conditions at the time of encoding are present at the time of retrieval
69
Context-dependent learning
superior retrieval when the external context of the original memories matches the retrieval context.
70
State-dependent learning
superior retrieval of memories when the organism is in the same physiological or psychological state as it was during encoding.
71
Mood-dependent learning
Related to state-dependent, can create a retrospective bias, remembering bad times more clearly or skewed when angry or depressed. (Can also be a result of an unfortunate upbringing creating a more angry or depressed adult)
72
Long-term potentiation
long lasting strengthening of the connections between two neurons after synchronous activation
73
LTP
Long Term Potentiation
74
Where does LTP (long term potentiation) occur in the brain?
Hippocampus, and amygdala and neocortex to a lesser extent. More specifically, where the sending neuron releases the neurotransmitter glutamate into the synaptic cleft.
75
Synaptic cleft
space between sending and receiving neurons.
76
Which receptors do the glutamate activate?
NMDA and AMPA
77
LTD
Long term depression
78
Long term depression
occurs when repeated low frequency patterns of activation of synaptically connected neurons, resulting in "less wiring together"
79
LTD vs LTP
LTD acts to balance out LTP and help synaptic connections reset, allowing for new and updated information to be encoded. Otherwise we could potentially reach a maximal point and no more learning could occur.
80
Important structure for the processing of emotion, especially fear
amygdala
81
Important structure for the formation of new memories
hippocampus
82
Retrograde amnesia
lost memories of the past
83
anterograde amnesia
lose capacity to form new memories, most common of the amnesias
84
Generalized amnesia
loss of all details of one's past, very very rare
85
HM (3 points)
- Man who had left and right hippocampi removed at 26 to prevent violent seizures, which resulted in complete anterograde amnesia. - He did, however, seem to retain implicit memory in some cases. - surrounding cortex and amygdala were also damaged during surgery
