memory Flashcards
State what memory involves and what memories are
Memory involves encoding, storage and retrieval of information. Memories include past experiences, knowledge and thoughts
Describe the route that information can take when entering the brain
All information entering the brain passes through sensory memory and enters short-term memory (STM). Information is then either transferred to long-term memory (LTM) or is discarded
explain what sensory memory is
Sensory memory retains all the visual and auditory input received for a few seconds and only selected images and sounds are encoded into the short-term memory
Explain what short term memory (STM) is
Short-term memory (STM) has a limited capacity and holds information for a short time
explain chunking
The capacity of STM can be improved by “chunking”. Chunking involves grouping items together to make a single item e.g. phone numbers
explain working memory model
STM can also process data, to a limited extent, as well as store it. This “working memory model” explains why the STM can perform simple cognitive tasks e.g. counting door in your house from memory.
explain STM rehearsal, displacement and decay
Items can be maintained in your STM by rehearsal and lost by displacement and decay.
explain the serial position
The serial position effect influences items entering the STM. Those items that enter first and last are better recalled than the intermediate items.
Explain what long term memory (LTM) is
Long-term memory (LTM) has an unlimited capacity and holds information for a long time.
explain LTM rehearsal
Rehearsal is regarded as a shallow form of encoding (converting nerve signals into a form the brain can receive) and involves repetition.
explain LTM organisation
Organisation is a method of encouraging transfer of information to LTM by adding structure e.g. grouping similar items together.
explain LTM elaboration
Elaboration is regarded as a deeper form of encoding which leads to improved information retention. Elaboration involves adding meaning/picture to things
explain contextual cues
Retrieval is aided using contextual cues. Contextual cues relate to the time and place when the information was initially encoded into the LTM.
