What did Miller (1956) find out about human memory?
Answer
That it is very limited in capacity
That it can only store 7 plus or minus 2 items or 'chunks'
Question 2
Question
Which research study showed that the duration of STM is limited to under 30 seconds, if items are not rehearsed?
Answer
Walker et al. (2003)
Peterson & Peterson (1959)
Baddeley (1966)
Question 3
Question
Which of the following is a type of long-term memory (LTM)?
Answer
Episodic - memory for events
Semantic - memory for facts
Acoustic - memory for sounds or words
Procedural - memory for skills
Question 4
Question
What were the conclusions of Walker et al.'s (2003) study?
Answer
There are 3 processes of memory - encoding, storage and retrieval
Unbroken sleep is important for memories to be consolidated
When retrieved, procedural memories can be changed/edited
Question 5
Question
Which of the following is a definition of the memory process 'storage'
Answer
Retaining information for period of time, until it is needed
Putting information into a memory store in the correct 'code'
Getting required information from a store when needed
Question 6
Question
Which type of memory retrieval is generally easier to do - recognition or free recall?
Answer
Recognition
Free recall
Question 7
Question
If you see a picture of a celebrity and try to remember his/her name, what type of retrieval is this?
Answer
Recognition
Free recall
Question 8
Question
In Baddeley's (1966) study of encoding, what type of items did participants make a lot of errors with in STM?
Answer
Acoustically similar e.g. 'can, cab...'
Semantically similar e.g. 'large, huge...'
Question 9
Question
Why did Baddeley (1966) find a difference between semantic/acoustic encoding in STM and LTM?
Answer
Because both stores use the same type of encoding but use them for different lengths of time
Because STM mainly uses acoustic encoding and LTM uses semantic encoding
Because STM cannot hold more than 7 items
Because people generate a visual image in the task, and it's hard to visualise semantically similar items
Question 10
Question
Which of the following evaluation points apply to many early studies of memory e.g. Peterson & Peterson (1959, Baddeley (1966)
Answer
They lack ecological validity because they used artificial tasks
They were field experiments, and so there were many distractions such as background noise
They focused on verbal information and can't tell us much about visual memory
They were highly unethical
They were conducted before researchers understood that there are different stores within both STM and LTM
Question 11
Question
Which of the following is an example of episodic LTM?
Answer
Remembering the name of the capital of Germany
Remembering where you went for your last summer holiday
Remembering how to drive
Question 12
Question
Scenario: You are asked for the name of a theory in Psychology, and although you are sure that you know it, you can't remember what it is called. You think that it is a short word, and if you heard the first letter you would probably remember it.
What is this problem with retrieval called?
