Q

Long Term Memory

A

Hold information for hours, days, weeks, or years

  • hippocampal region of the brain is critical for putting new information into the long term store
  • some information may be lost over time

Q

Multiple Forms of Memory

A

Explicit and implicit memories are distinct from each other. Thus, a person with amnesia may lose explicit memory yet display implicit memory for material that she or he cannot consciously recall learning.

Q

Recognition

A

encoding an input and matching it to a stored representation

(i.e. reading something over and over again)

(typically easier than recall)

25
Semantic Network
mental grouping of concepts that share similar properties * leads to easier retrieval of similarly related ideas * easier to remember and retrieve things if they are organized into semantic networks
26
Anterograde Amnesia
the inability to transfer new infor from the short term store into the long term store.
27
Retrograde Amnesia
The inablity to retrieve infor thtat was acquired before a particular date, usually the date of an injury or peration
28
Consolidation
a process by which memories become stable in the brain * a boost from sleep * thinking, recalling, and talking about it contributes to consolidation
29
Reconsolidation
Memories can become vulnerable to disruption when they are recalled, thus requiring them to be consolidated again * Memories aren't given perfect tenure after all
30
"Cells that fire together wire together"
sending signals across the synapse strengthens the connection between neurons * happens in the _hippocampus _ * which is crucial for storing long term memory
31
Long-Term Potentiantion (LTP)
a process whereby communication across the synapse between neurons strengthens the connections making further communication easier * Properties * Occurs within several pathways of the hippocampus * induced rapidly * lasts for a long time
32
NMDA Receptor
* influences the flow of information between neurons by controlling the initiation of LTP in most hippocampal pathways
33
Retrieval Cue
* external information that is associated with stored information and helps bring it to mind
34
Encoding Specificity Principle
A retrieval cue can serve as an effective reminder when it helps re-create the specific way in which information was intitally encoded
35
State-Dependent retrieval
The tendency for information to be better recalled when the person is in the same state during encoding and retrieval * lose keys drunk? get drunk to refind keys
36
Transfer-Appropriate processing
Memory is likely to transfer from one situtation to another when the encoding context of the situations match * taking a test in the room where you learned the information
37
Info about Retrieval
Retrieval can strengthen a retrieved memory, making it easier to remember that information at a later time
38
Retrieval-induced forgetting
a process by which retrieving an tiem from long-term memory impairs subsequent recall of related items
39
Sucessful vs. Unsucessful Recall
Sucessful: High levels of recall = hippocampus increased activity Unsucessful: Low levels of recall = the left frontal love showed increased activity
40
Explicit Memory
Occurs when people consciously or intentionaly retrieve past experiences
41
Implicit memory
past experiences influence later behavior and performance, even though people are not trying to recollect them and are not aware that they are remembering them
42
Procedural Memory
the gradual acquistion of skills as a result of a practive or "knowing how" to do things
43
Priming
an enhanced ability to think of a stimulus, such as a word or object, as a result of a recent exposure to the stimulus * associated with reduced activity in various regions of the cortex that are activiated when people perform and unprimed task * perceptual priming * reflects implicit memory for the sensory features of an item (right cerebral hemisphere) * Conceptual Priming * implicit memory for the meaning word or how you would use an object (left hemisphere)
44
Semantic Memory
a network of associated facts and concepts that make up our knowledge of the world
45
Episodic Memory
The collection of the past personal experiences that occured at a particular time and place
46
Hippocampus info
the hippocampus is not necessary for acquiring new semantic memories
47
Transience
forgetting what occurs when later learning impairs memory for information acquired earlier * shift from specific to general memories
48
Retroactive Interference
Occurs when later learning imparis memory for information acquired earlier * example: work on monday, keep working until friday and then forgot what you did on monday
49
Proactive Interference
the situations in which earlier learning impairs memory for information acquired later * park in the same parking lot every day, one day you go to get your car and you can't remember where you parked it because you've done it so often
50
Absentmindedness
A lapse in attention that results in memory failure
51
Frontal Lobe info
Greater activity in lower left frontal region during encoding is associated with better memory
52
Prospective memory
remembering to do things in the future
53
Blocking
A failure to retrieve information that is available in memory even though you are trying to produce it * damange to parts of the left temporal lobe on the surface of the cortex, most often as a result of a stroke * Strong activation of regions within the temporal lobe when people recall proper names
54
Memory Misattribution
assigning a recollection or an idea to the wrong source
55
Source Memory
recall of when, where, and how information was acquired
56
True or False: the frontal lobes play a significant role in effortful retrieval processes
True
57
False recognition
a feeling of familiarity about something that hasn't been encountered before
58
Suggestibility
the tendency to incorporate misleading information from external sources into personal recollections
59
Bias
the distorting influences of present knowledge, beliefs, and fellings on recoolection of previous experiences
60
Persistence
the intrusive recollection of events that we wish we could forget
61
Flashbulb Memories
detailed recollection of when and where we heard about shocking events * Damaged amygdala patients do not remember emotional events any better than non emotional events
62
Shollow process vs. Deeper Processing
Shallow = leads to little memory Deeper = leads to greater memory We are better able to remember things if there is a deeper processing of it
63
Three Stage Memory Model
* Sensory Memory * Hear, smell, see something * Short Term * stores in short term * 30 seconds or less * Long Term * After you think about it * relatively permanent but not necessarily accesible * Info goes from LTM to STM to be used
64
The Flow of Information through the Memory System
Information moves through several stages of memory as it gets encoded, stored, and made available for later retrieval.
65
Elaborative Rehearsal
memory technique that involves thinking about the meaning of the term to be remembered, which leads to the creation of a semantic network
66
Various Areas of the Brain and their relationship to Memory
* Amygdala * Emotional Memory * Basal Ganglia & Cerebellum * Creation and storage of basic memory and implicit memories * Hippocampal Formation * Memory Recognition * Implicit/Explicit Memory * Declarative LTM * Thalamus * Formation of new memories * spatial and working memory * Cortex * Encoding of explicit memory * Storage of memory * Skill learning, priming, working memory
67
Confabulation
Honest Lying people with alzheimer's or damage to frontal lobe make up stories to compenstae for loss of memory about certain facts
68
7 Sins of Memory
1. Transience 2. Absentmindedness 3. Blocking 4. Memory Misattribution 5. Suggestibility 6. Bias 7. Persistence
