28
Define memory and list the 3 mental processes that allow memory functions
Memory is the ability to
Encode, Store, and Retrieve information
29
Define encoding
Any learning strategy that allows you to form a memory
30
Define storage
Keeping the memory for some amount of time
31
Define retrieval
Recalling the memory when you need it
32
Give an example of encoding nuerodiversity
Some students need to repeatedly study the same thing over and over whereas other students only need to go over the material once
33
List 1 thing that can enhance your encoding abilities
Use the personal relevance strategy and relate information to your life/life experiences
34
List 8 active encoding strategies for students
1) sitting in front row helps stay focused
2) turning off phones prevents distraction
3) writing notes on paper more effective for most
4) formatting notes to isolate key terms
5) staying engaged with class discussion
6) asking questions to clarify
7) sharing notes or study groups
8) making flashcards
9) deciding information is important useful and want to remember
35
What is the Von Restorff effect?
When you make something stand out in your notes such as highlighting or circling it
36
Explain the distributed approach to encoding
Managing your time and studying the material repeatedly over many days (avoid cramming)
37
What is maintenance rehearsal?
Rote repetition without truly valuing the information (like children memorizing the pledge of allegiance without understanding the words)
38
What is elaborative rehearsal?
Repetition of material but deciding information is very valuable and useful to you, this focus helps you truly understand and learn in less time
39
Define encoding capacity
The amount of information you can actively encode before you start forgetting (before writing down to study later)
40
What was the encoding capacity of humans in the 1950s
7 +/- 2
41
Who did 1950s research on encoding capacity of humans?
George Miller
42
What was the encoding capacity of humans in more recent years according to multiple researchers?
4 +/- 1
43
What does research indicate is the cause of humans having less encoding capacity now than in the 1950s
Reliance on technology rather than their own brains
44
What happens to your brain if you rely on electronics devices rather than your brain?
Your brain becomes less able to encode, store and retrieve information (your memory gets worse)
45
Define storage capacity
The amount of information you can store in your brain (the brain is built to grow and expand; plasticity)
46
True or false. Humans have an unlimited storage capacity for memories?
True
47
Define storage duration
The length of time you can hold information in your brain (with maintenance the brain can store for unlimited time)
48
What usually prevents humans from keeping all of the memories they have stored?
We don't make time to occasionally review the information
49
What is required to keep memories we have stored?
Maintenance, you must occasionally use/review/think about them or you will lose them
50
What is a retrieval cue?
Anything that triggers a memory to pop up into your consciousness
51
List 6 things that can help you retrieve stored memories
1) a question
2) a smell
3) a location
4) a color
5) time of year/holiday
6) a person
52
What are memory tags?
Aspects/features that you are unconsciously attaching to a memory when you encode it
53
Why is it better to have more memory tags?
The more memory tags you form along with the main memory, the easier it is to retrieve that memory. (Memory tags turn into retrieval cues and help recall your memory)
54
Give an example of an auditory tag
Reading questions in your professors voice during an exam or when you think of someone talking you hear their voice
55
Define or give an example of the encoding/retrieval specificity principle
The way you encode impacts the way you retrieve. If you only encode in one specific way that may be the only way you can retrieve that information
Ex: listing months of the year alphabetically
56
Define or give an example of the context effect
We often form a memory tag related to our surrounding when we form a memory so it's easier to recall information when we return to that location/context/setting.
Ex: if you lose your keys retrace your steps and when you back into the right room you'll remember where you put them
57
Define or give an example of the mood congruence effect
We often form a memory tag related to our mood when we form a memory so it's easier to recall information when we get in the same mood.
Ex: when you are sad you tend to think of negative things and find it hard to think of positive things
58
Define or explain the Serial Position effect
We tend to remember the beginning and end of things; if we remember the beginning only that's the primacy effect whereas the end only is the recency effect
Ex: remembering the begining/ending of a movie but not all the character development in the middle
59
Define or give an example of the state-dependant effect
We tend to encode our physical state along with the information so it's easier to recall that information when we return to the same physical state.
Ex: if you are always hungry when you study you should take a test when you are hungry
60
What are explicit memories?
Conscious memories that are easy to talk about/explain/declare verbally
61
What is an episodic explicit memory?
Memories of our personal life events (often linked with some emotional content)
62
What an Autobiographical explicit memory?
Episodic memories with a running time-line of non-emotional elements (the year, location, weather etc)
63
What is a semantic explicit memory?
Factual or knowledge-based information (non-emotional content) stuff you learn in classes
64
What is a flashbulb explicit memory?
Memories with intense emotions (often trauma-induced) you can feel like you're reliving the moment when you have the memory
65
What are implicit memories?
Unconscious memories (you're not aware of and therefore can't explain them easily)
66
What is a procedural implicit memory?
Muscle memories, your body's muscles learn how to do things so that you don't have to consciously think about walking, writing etc (anything you can do without conscious thought)
67
What is an echoic implicit memory?
Auditory memories; you're unconsciously storing overlapping sounds... These usually become memory tags but they're also available in case you need to retroactively recall a recent sound
68
What is an iconic implicit memory?
Visual memories you're unconsciously storing overlapping images... These usually become memory tags but they are also available if you need to retroactively recall a recent visual
69
What is a sensory implicit memory?
All your senses can become memories and memory tags; you're unconsciously storing smells, touch/sensations, tastes etc. (echoic and iconic are also examples of sensory memories)
70

77
What is the relationship of the Olfactory bulb to memory?
Smell-related aspects of memories
78
What part of the brain is most used for memory?
Hippocampus
79
Explain memory according to the Semantic Network Model
This model says memory is like a complex network of association based on the idea that memory builds upon itself (using scaffolding techniques)
80
Give an example of scaffolding in relationship to memory
A teacher explains a concept (e.g. adding) then demonstrates how to use that information and challenges students with a task using that knowledge (e.g. homework or a test). Once a student has displayed solid understanding, the teacher can build on that foundational knowledge to explain higher level knowledge (e.g. multiplication)
81
True or false. Memories distort over time?
True
82
What is a schema?
Performed ideas based on past experiences that allow you to fill in gaps of your memory when you reconstruct a memory
83
Give an example of a schema in relation to memory
You can roughly tell me what you "remember" about the Halloween seven years ago (not be sure you remember that specific Halloween but because You've had so many of them you know what usually happens)
84
Explain the Memory Consolidation Model
This model says memory is like making jello... A process that starts when you encode (mix ingredients together), store (refrigerate until mix is solid) and finally retrieve (use/eat after consolidated) if something interferes with the process, you don't form a memory or lose it (like if you take jello out of the refrigerator too soon)
85
List 2 things your brain needs to consolidate memories
Sleep and repeatedly reviewing memories. The consolidation process for human memory occurs when you sleep and repeatedly review memories
86
What happens if you don't do the 2 things your brain needs to consolidate your memories?
If don't get proper rest after forming a memory or don't occasionally review your memories you lose them
87
What 2 things interfere with your consolidation process?
Not getting enough sleep
Not occasionally reviewing your memories
88
List the 3 stages in the Stage Model of Memory
Sensory memory
Short term memory
Long term memory
89
Describe sensory memory and it's capacity and duration in the stage model of memory
Large capacity but small duration (you must be paying attention to something in order for it to move into the next stage)
90
Describe short term memory and it's capacity and duration in the stage model of memory
4-7 item capacity and ~20 second duration (active encoding strategies help)
91
Describe long term memory and it's capacity and duration in the stage model of memory
Unlimited capacity and unlimited duration... You can keep adding new memories (they do not replace old ones) as long as you occasionally review them, you won't lose them
92
What is highly superior autobiographical memory?
A rare type of memory where the person has extremely accurate autobiographical memories... If you ask about a random day 20yrs ago they can recall almost every detail
93
List 4 things all memory models agree on
1) much of what we experience isn't encoded
2) we neglect to maintain our stored memories and lose them
3) we often can't retrieve what is stored

True or false. Your encoding of events and information is different than someone next to you having the same experience
True
97
Who is one of the top memory research psychologists regarding memory distortion?
Elizabeth Loftus
98
Explain the memory distortion concept, the misinformation effect
If when you are recalling a memory, you get some false or misleading information, it will distort the recollection/reconstruction of that memory
Ex: remembering bug bunny at Disney land
99
Explain the memory distortion concept of imagination inflation
If you imagine something is true you can form and entire false memory of it; unlike the misinformation effect which distorts an existing memory, this feature of memory allows you to create a memory of something that never happened without your conscious awareness.
Ex: remembering a terrifying experience of being lost in a mall that never actually happened
100
Explain the memory distortion concept of change blindness
Humans don't pay attention to things changing directly in front of them and therefore don't notice those changes
Ex: changes in a set between scene in a movie
101
Explain the memory distortion concept of color & sound interpretation/perception
Human brains process sensory information uniquely depending on a wide variety of factors which is why two people looking at the same thing or listening to the same thing will report seeing/hearing different things
Ex: blue/black or white/gold dress
102
True or false. Most eye witness testimonies are extremely accurate?
False
103
List 5 steps to avoid distorting the memory of an eye witness
1) do not offer multiple choice
2) have eyewitness go through photos one at a time
3) inform the. Your database is limited and might not have the person they saw
4) time them to ensure true recognition occurs which happens <20secs
5) if they select someone do not say anything
6) use an impartial person to ask open ended questions
104
Explain the Decay Theory of Memory loss
As you age your mind naturally starts to lose a variety of cognitive functioning including memory, so we should expect memories will decay over time/your lifespan
105
Explain the Inhibited Retrieval Theory of Memory loss
Memory loss isn't necessarily a natural part of aging. Many people report that they suddenly remember something that they haven't thought about for 30yrs. This indicates memories may still exist even if we can't retrieve them... Memory loss may just be about retrieval que problems
106
Who did research resulting in the "forgetting curve"?
Hermann Ebbinghaus
107
What are 2 findings in the forgetting curve?
1) Humans experience rapid forgetting shortly after a learning opportunity (due to ineffective encoding)
