Q

Describe the Mcgeoch and Mcdonald case study

A

-studied retroactive interference
-ppt learned list of words
-ppt given a 2nd list of either words or numbers to learn
-ppt asked to recall first list
-the more similar the second list to the first the worse the recall of the first

Q

What’s a strength and a limitation of the Mcgeoch and Mcdonald case study

A

A- supports theory, new list interfering recall of old list
D- Low external validity, the time gap between learning and recall in the study is very short, so there’s an exaduration of the effects of interference

Q

Describe the procedure and findings of Baddeley and Hitches study

A

-asked rugby players to recall all matches in season (inc team names and scores)
-players had better memory of the teams if they had played less games
-but how long ago the matches were wasn’t important

findings
-Shows interference is due to similarity rather than time

Q

What are 2 strengths of Baddeley and Hitches study?

A

-Supports interference, shows similarity increases interference as more games planed inc interference
-natural study, high external validity shows interference occurs in real life

Q

What’s 2 strengths of Burke and Skrull’s study?

A

In real-life applications, advertisers know not to place similar products near each other or people may forget
-Uses real-life material so high external validity

Q

How does research into the effects of interference have useful real-life applications?

A

in advertising, we know not to place similar adverts close together as people more likely to forget the products

when revising choose different topic areas rather than revising similar theories close together

15
Q

how is time between learning a disadvantage of the interference theory?

A

time between learning- most studies have a short time between learning the two sets of materials so it exaggerates the effects of interference

17
Q

What 3 things effect interference?

A

-similarity
-time between learning
-use of cues

18
Q

How do all 3 studies support interference theory?

A

They all prove similarity increases inteference

19
Q

Describe the case study of Marvin

A

-Marvin takes french and Spanish and he mixes up the word ‘chair’ as they are similar languages- shows similarity inc interference

20
Q

What is retrieval failure?

A

The reason for forgetting in LTM

It occurs when the material to be recalled is available but it isn’t accessible because of a lack of a suitable cue

21
Q

What is meant by context-dependent forgetting?

A

forgetting information because you’re in a different place to when you learned the information

22
Q

What is meant by state-dependent forgetting?

A

forgetting information as you’re in a different internal state to when you learned the information

23
Q

What is meant by the encoding specificity principle?

A

Tulving
This states that a cue that helps us recall information has to be present at encoding (learning) and at retrieval. If not forgetting can occur

24
Q

describe the procedure of Godden and Baddeley’s study

A

Studied- context depending forgetting
Divers learned and recalled a list of words in 4 conditions
1-learned on land recalled in water
2-learned on land recalled on land
3-learned in water recalled on land
4-learned in water recalled in water

25
Q

describe the findings of Godden and Baddeley’s study

A

-ppt recalled best if they learned and recalled in the same context/place which shows context acts as a cue for recall

26
Q

Give a strength of Godden and Baddeleys study

A

it supports retrieval failure as it shows context/place acts as a cue for recall

27
Q

What are 2 limitations of Godden and Baddeleys study

A

-low external validity, don’t often learn word lists underwater
-exaggerated effects of retrieval failure, being on land and in water are 2 very different contexts from each other.

28
Q

describe the procedure of Goodwin et al 1969 study

A

he tested for state-dependent forgetting
-asked PPT to learn and recall a variety of tasks (word association) in diff states;
1-learn sober, recall sober
2-learn sober, recall drunk
3-learn drunk, recall sober
4-learn drunk, recall drunk

29
Q

describe the findings of Goodwin et als study and explain why

A

groups 1 and 4 performed best because their internal state is the same at learning and recall

30
Q

what does goodwins study tell us about state-dependent forgetting?

A

that internal state ascts as a cue for recall so if the state is different at learning and recall this leads to retrieval failure

31
Q

give a strength of Goodwins study

A

he was backed up by other researchers
-one found that chewing gum in a lesson and chewing the same flavor gum in an exam on that info acted as a cue

32
Q

give a limitation of Goodwins study

A

low mundane realism as the tasks do not reflect things we forget in every day life

33
Q

what 2 types of cues are there?

A

context-dependent cues
state-dependent cues

34
Q

What are context-dependent cues?

A

Relate to the place we are in when we encode new memory. being in this place when recalling the memory will act as a cue

35
Q

What are state-dependent cues?

A

relate to how learners feel when they encode new memories. Being in this state when trying to recall the memory will act as a cue

36
Q

How do the findings of either of these studies support the effects of state-dependent forgetting memory?

A

Goodwin- having the same internal state when learning acts as a cue for recall
Godden- recalling in the same place/context as info is learnt acts as a cue for recall

37
Q

what are 2 strengths of retrieval failure?

A

-lots of studies to support (Godden and goodwin)
-lots of real-life examples of cues aiding memory

38
Q

How does research into the effects of retrieval failure have useful real life applications?

A

Abernathy- found students do better in exams if they do them in the same room where they learned the info
Smith- found thinking about the room you learned it is just as effective

39
Q

What are 2 limitations of retrieval failure?

A

-retrieval cues don’t always work
-circular explanation of encoding specificity principle

40
Q

Why don’t retrieval cues always work?

A

relying on things like state or context as a retrieval cue isn’t always effective as many things we learn and complicated and multi-faced (more than 1 layer to it) so cues are rarely effective when helping us to remember them

41
Q

Why is the encoding specifically principle difficult to test?

A

because Baddeley argued that a lack of cues may not be the reason that forgetting has occurred so we cannot be sure
