Q

how is the amygdala involved in classically conditioned emotional memories

A

the amygalda encodes the memory of a response learnt through the assocition of a neutral stimulus and unconcious response to produce a concious response

Q

how does the amygdala strengthen explicit memories (specific/neurohormone related)

A
  • during heitghened emotional arousal, the FFF response releases adrenaline
  • adreniline triggers the release of noradrenline in the amygdala
  • noradrenline then stimulates the amygalda to send neural signals to the hippocampus to store the relevant emotional detials of explict memores

Q

what does the basil ganglia communicate with and why

A
  • the cerbellum as it is also involved in encoding and tempory storage of implicit procedual memoires

Q

where is the cerebellum located

A

at the base of the brian

15
what is the main role of the cerebellum (same as basil)
to enconde and temporalily store implict procedual memoires
16
what is the other role of the cerrebumllum that is unique
the cerebullum is responsible for reflex responses learnt through classical conditioning such as blinking
17
does the cerebullum store anything in the long term
no, implicit procedual memoires are stored in the long term in the neocortex
18
what is memory
memory is the processing, storage and retrivial of information through learning
19
what is encoding
encoding is the conversion of information into a usable form so that it can be neurologically represented in memory in the brain
19
what is storage
storage is the retention of encoded information
20
what is retrivial
retrivial is brining stored info into our concious awareness
20
what does the attkinson and shiffrin model of memory suggest
- memory involves multiple systems - there are 3 different stores of memory
21
what are the 3 seperate memory stores
- sensory memory - short term memory - long term memory
22
what is sensory memory
sensory memory is the entry point for all incoming information
22
how is sensory memory stored
in its raw form
22
what is the capacity of sensory memory
unlimted
22
are we conciosuly aware of our sensory memory
we are NOT conciouslly aware of our sensory memory
23
what are the two main forms of sensory memory that we are studying
- inconic memory - echoic memory
24
what is iconic memory
iconic memory is our visual sensory memory
25
what is the duration of our iconic memory
0.3 seconds
26
what is echoic memory
echoic memory is our auditory sensory memory
27
what is the duration of our echoic memory
3 seconds
28
what is the role of short term memory
short term memory stores an encoded version of the information transfered from our sensory memory or retrieved from our long term memory for a period of time
28
what is the duration of short term memory
30 seconds
29
what is the capacity of short term memory
7+-2 (5-9)
29
is short term memory concsious
yes, our short term memory is our only conscious memory store
30
what does chunking do
chunking allows for more information to be stored in short term memory beyond the limit of 7+-2, by chunking information into items
31
how is the capacity of short term memory increased
chunking
32
how is the duration of short term memory increased
maintence rehersal
33
what is maintaince rehersal
maintance reheral is repeating the content in short term memory over and over to increase duration beyond 30 seconds
34
what is the capacity and duration of long term memory
unlimted
35
what is elaborative rehersal
elaborative rehersal is the process in which memoires are encoded from STM into LTM
35
is long term memory concsious or unconcsious
unconcious
36
how does/can elabortive rehersal work
- linking new information to already stored infromation into LTM - using meaningul/personal memoires in LTM to make connections
37
what is retrivial
retrivial is the process in which memories are transferred from our LTM into our concsious awareness, STM
38
how can memories be retrieved
- retrvial cues (song, scent) - context ( same enviroment) - recognition (multi-choice questions)
39
what are some strengths of the attkinson and shiffrin model of memory
- the model distinguishes between the different stores involved in memory - the model outlines that each memory store has a different capacity and duration - findings from memory studies support the distinction between STM and LTM outlined in the model
40
what are some limitations of the attkinson and shiffrin model of memory
- the model may be considered oversimplified espicailly concering LTM
