Q

levels of processing theory

A

The idea that memory depends on how information is encoded, with better memory being achieved when processing is deep than when processing is shallow.

Q

shallow processing

A

Repetition with little attention to meaning, usually associated with maintenance rehearsal, attention is focused on a word’s physical properties

Q

deep processing

A

Involves attention to meaning and relating an item to something else, usually associated with elaborate rehearsal, results in better memory

Q

paired-associate learning and what it is used to test

A

A learning task in which participants are first presented with pairs of words, then one word of each pair is presented and the task is to recall the other word. used to test whether visual imagery can enhance memory

Q

how can memory be enhanced?

A

memory for a word can be increased by (a) forming visual images, (b) linking words to yourself, (c) generating the word during acquisition, (d) organizing information, (e) rating the word in terms of survival, and (f) practicing retrieval

Q

Effective studying techniques

A

1.Elaborate; relating info to things you already know,
2.Generate and test yoursef,
3. Organize; ex. trees, grouping similar facts/principles, chunking,
4. Take breaks,
5. Avoid illusions of learning; ex. farmiliarity effect
6. Be an active note taker; don’t take notes on the computer

Q

spacing effect

A

enhanced performance caused by shorter study sessions and taking breaks

19
Q

free recall

A

participant asked to recall stimuli

20
Q

cued recall

A

recall with retrieval cues, typically words or phrases

21
Q

encoding specificity

A

match context in which coding and retrieval occur; we learn info together with its context, ex. coding memories at a house and then remembering upon returning to that house, diving experiment

22
Q

state-dependent learning

A

match internal mood/awareness present during encoding and retrieval

23
Q

transfer-appropriate processing

A

match the cognitive task involved in encoding and retrieval/ matching the type of processing in encoding and retrieval, ex. focusing on the sound of a word vs. the meaning
memory is enhanced when the type of coding during acquisition matches the type of retrieval on a memory test

24
Q

consolidation

A

the process that transforms new memories from a fragile state, in which they can be disrupted, to a more permanent state, in which they are resistant to disruption, ex. learning lists of non-sense syllables with vs. without a delay

25
synaptic consolidation
structural changes at synapses that take place over minutes or hours
26
systems consolidation
gradual reorganisation of neural circuits in the brain over months or years
27
Hebb's theory about formation of memories
synaptic changes provide a record of experience; formation of memories is associated with structural changes at the synapse, translated into LPT
28
long-term potentiation (LPT)
outcome of structural change at the synapse; strengthening of synaptic transmission/ increases firing in a neuron due to prior activity at the synapse
29
standard model of consolidation
Proposes that memory retrieval depends on the hippocampus during consolidation, but that once consolidation is complete, retrieval no longer depends on the hippocampus, but on cortex
30
reactivation
A process that occurs during memory consolidation, in which the hippocampus replays the neural activity associated with a memory. During reactivation, activity occurs in the network connecting the hippocampus and the cortex. This activity results in the formation of connections between the cortical areas. helps form direct connections between the cortical areas. especially strong during sleep
31
retrograde amnesia
loss of memory for what happened prior to and injury or traumatic event, can extend back to minutes or years
32
graded amnesia and what does it correspond to
characteristic of retrograde amnesia, amnesia tends to be most serve for events happening closer to the injury than for earlier events, corresponds to the standard model
33
anterograde amnesia
amnesia for events that occur after an injury (inability to form new memories)
34
multiple trace model of consolidation
hippocampus is involved in the retrieval of remote memories (especially episodic) vs. standard model which proposes hippocampus is only involved in the retrieval of recent memories
35
when do hippocampus responses change
for stimuli that have lost their episodic character
36
multivoxel pattern analysis and what did it show?
procedure for determining pattern of voxel activation that is elicited for specific stimuli within various structures, showed hippocampus is active for retrieval of remote memories
37
classifier
computer program trained to recognise patterns of voxel activation
38
memory and structures of the brain
more info about remote vs. recent memories was in the prefrontal cortex, hippocampus contain info about remote and recent memories, with more info on remote memories in the posterior hippocampus and recent memories in the anterior hippocampus
39
why does sleep after learning enhance memory?
eliminates environmental stimuli that interfere with consolidation
40
memory is stronger when
when you are expected to be tested, we selectively consolidate memories that might be useful
41
reconsolidation
when a memory is retrieved it becomes fragile again and needs to be consolidated again updating memories, Nader rate experiment
42
practical outcome of reconsolidation training
alleviate symptoms of PTSD, propranolol
43
temporal context model
old contexts can become associated with new memories , contextual associations
