Paper 1 Memory Flashcards
What are the 5 stages of memory?
- Input (Info enters the memory process using all 5 senses)
- Encoding (The way info is represented in the memory store)
- Storage (Holding info until it is needed)
- Retrieval (Locating info in memory and getting it out when needed)
- Output (Memories)
Define Sensory memory?
A number of memory stores which hold incoming sensory information for very short periods of time
Define STM?
Situations/ events that take place in the present or immediate past
Define LTM?
Events that occurred in the distant past
Define Capacity?
How much memory can be stored
Define Duration?
How long the memory lasts
Encoding
The way in which information is changed so that it can be stored in the memory. 3 main ways: visual, acoustic, semantic
Define Attention?
The cognitive process of selectively concentrating on one aspect of the environment while ignoring other things
Define Rehearsal?
Repetition of information
Sensory memory- duration, capacity and encoding?
Duration: Millieseconds/ brief
Capacity: Very large
Encoding: Multimodal/ sense specific
STM memory- duration, capacity and encoding?
Duration: 18 seconds
Capacity: 7+/- 2 items
Encoding: Acoustic
LTM memory- duration, capacity and encoding?
Duration: Unlimited
Capacity: Unlimited
Encoding: Semantic
STM- Who conducted research into duration, capacity and encoding?
Duration: Peterson and Peterson
Capacity: Jacobs
Encoding: Baddeley
LTM- Who conducted research into duration, capacity and encoding?
Duration: Bahrick
Capacity: N/A
Encoding: Baddeley
Describe the multistore model of memory?
It is a linear model that explains the process of creating a memory.
It consists of 3 stores which are unitary and separate and 4 processes.
Information from the environment enters the sensory memory store (key features). Information then enters STM (Key features) through the attention process which selects what information will pass into STM by filtering out unnecessary information. To enter LTM (Key features) memories go through maintenance rehearsal, the more it’s rehearsals the better it can be remembered. In order to get information out of LTM back into STM it must go through the retrieval process.
Evaluate the MSM?
Positive: Serial position effect
Positive: Brain damage case studies
Negative: Flashbulb memory
Negative: KF case study
Describe the working memory model?
Only a model of short term memory.
Information enters the central executive through the attention process in which it is then directed to one of 3 slave store; phonological loop, visuo-spatial sketchpad or the episodic buffer.
Features of the central executive?
Directs attention to particular tasks. Controls the other slave systems. Determines how resources will be allocated. Drives the system. Decides how attention is directed. Allocates the resources.
Features of the phonological loop?
Controls auditory information.
Subdivided into the phonological store (Inner ear) and the articulatory process (Inner voice)
Inner ear: holds info in speech based form for 1-2 seconds.
Spoken words enter directly.
Eg. Listen to someone speak.
Inner voice: written words enter indirectly after being converted sub-vocally.
Rehearsal takes place here.
Eg. Read a book.
Features of the Visuo-spatial sketchpad?
Processes visual and spatial info.
How things look and where they are, relationship between things.
Holds info for a very short time.
Eg. Catching a ball.
