Q

The method of Bahricks high school photograph study (1975)

A

Bahrick tracked down gradutates over a 50 year period
392 graduates were tested
half where in the recall group to name people in there year book without a list of names
the other were in the recognition group asked to match the name to the persons photo with a list of names

Q

What did Miller develop to find upon the short term memory’s capacity?

A

The digit span technique and immediate serial recall found that people’s STM can only hold 7+/- 2 items

Participants listened to an 11 digit number string and immediately had to recall what they heard in the correct order
Digit span was the amount of numbers they could correctly remeber.

Q

The method of Peterson and Peterson’s study

A

Participants would be flashed a consonant trigram (3 consonant letters) and would have to count back in 3s from a number to prevent rehearsal and then after 3,6,9,12,15,18 seconds later would have to recall it

After 18 seconds only 10% could recall there trigrams,. Thus STM duration isnt longer then 18 seconds

Q

what are the 3 types of LTM?

A

Procedural - our knowledge of how to do things (associated with the cerebellum and frontal cortex)
Episodic memories- memories of specific life events and have been time stamped in our lives ( associated with the hippocampus and temporal lobe)
Semantic memory- our general knowledge of the world ( associated with the anterior temporal lobe)

Q

How does Clive wearing suggest there are multiple stores to the LTM?

A

has badly damaged episodic memory as cannot remember anything specific to himself but can remember how to play piano so has intact procedural memory

Q

what is the primacy and recency effect?

A

Proved the STM and LTM as separate stores
Beginning information presented would have been transferred to the LTM so can easily be recalled (primacy effect)
Information called out last would still remain in the STM so can be recalled ( recency effect) shown by the dip in the middle position where info has decayed

Q

what are flashbulb memories?

A

They are stored instantly and do not require rehearsal. However in the MSM storage in the LTM can only occur in rehearsal. memories with emotional significance can be remembered without rehearsal.

17
Q

Who created the MSM theory?

A

Atkinsons and Atkinsons

18
Q

Describe the central executive

A

It is to receive information from the visuospatial sketchpad, phonological loop and the long term memory to create and form decisions or actions
It has a very limited capacity and also is modality free

19
Q

Describe the phonological loop

A

Holds sounds that and rehearse words currently being considered
It has two stores
the phonological store to hold acoustically encoded items briefly
and the articulatory system which allows repetition

20
Q

Describe the visuo-spatial scratch pad

A

This stores visual information
with a capacity of 3-4 objects
Has two parts
the visual cache- stores information about shape and form
inner scribe - stores information about somethings position

21
Q

Describe the episodic buffer

A

This links the executive central and the LTM and links the the LTM to wider processes when the visual and acoustically encoded information combine

22
Q

What is proactive interference?

A

when past learning interferes with learning something new

23
Q

what is retroactive interference?

A

when current learning interferes with recalling something old

24
Q

what was the case of HM?

A

A patient who had his hippocampus removed
unable to form new LTMS but had functioning STMS

25
Q

What was the findings and conclusions of postmans investigations on retroactive interference ?

A

The group who were only asked to recall one group of words (control group) were more accurate then the experimental group
This suggests that learning items in the second list interfered with participant ability to recall the list

26
Q

What did chandler (1989) state

A

That students who study similar subjects at the same time often experience interference

27
Q

what were the findings of underwoods (1957) explanation on proactive interference

A

When the group who learnt a list of nonsense syllables and numbers had a lower rate of forgetting then those who had learnt multiple nonsense lists of syllables

28
Q

The findings of John McGeohand and william Mcdonald study on proactive interference

A

Compared to the control group, those who remembered the least had the synonym group as the second list (most similar)

29
Q

what is a retrieval cue?

A

A stimuli that can help you retrieve a certain memory such as the setting or mood

30
Q

What is the encoding specificity principle?

A

The idea that when a cue is present during the encoding of information and when it needs to be retrieved
The closer the cue to the target word the better the overall recall

31
Q

The findings of Tulving and Pearl stone

A

Participants would be presented with 48 words that belonged to 12 categories
When a cue was present the recall was 60%
when cue was not present the recall was 40%

32
Q

What is context dependent forgetting?

A

When retrieval failure cues due to the context of the place or the action being described

33
Q

what were the findings for Godden and Baddeley

A

Deep sea divers had a list of 40 words to remeber
some remembered them on land and some remembered them under water
When in the same place deep sea divers could recall more
Context is acting as the cue

34
Q

What were the limitations of GOoden and Baddelys experiment

A

The extreme difference between on land and under water , is rare in real life
so context probably plays a minimal role in aiding recall

35
Q

what is state dependent forgetting?

A

When our state of mind during encoding can also act a cue

36
Q

what evidence did Carter and Cassidy provide for state dependent forgetting?

A

Carter and cassidy gave anti-histamines which gave a seditiative effect to the control group followed by a recall task

Found the best recalled words were when they were in the same state as they encoded them in

37
Q

Limitations of the encoding specificity principle

A

The principle does not explain how some people can remeber without a cue despite either for context or state dependent forgetting

38
Q

What is a schema

A

In psychology, a schema is a cognitive framework or concept that helps organize and interpret information. Simply put, a schema describes patterns of thinking and behavior that people use to interpret the world.
