Memory Flashcards
Memory
The brain can capture images of sights, sounds, smells, tactile sensations, and emotions all experiences at one time and retain them as memories
Memory Levels
Information entering the brain passes through
-Sensory memory
-Short term memory
-Long term memory
Sensory Memory
Retains all of the visual or auditory input and lasts for a few seconds
Short Term Memory
Limited capacity and can only hold a limited amount of information
Chunking
Improves the capacity of short term memory, this is when several units are put together to create one meaningful unit
Working Memory Model
The short term memory can also process data to limited extent as well as store it, this explains why the short term memory can preform simple cognitive tasks
Serial Position Effect
Investigation memory span when shown a list of items, items at the beginning have been transferred into the LTM. Items at the end are still held in the STM, Items in the middle have been displaced by new information
Transfer of information from STM and LTM
Information from STM is either, transferred to long term memory or lost by displacement or decay
Displacement
Information is lost due to pushing out old information by new info
Decay
Information is lost due to a breakdown of a memory trace
Long term memory
Unlimited capacity and can hold information for a long time
Promotion of transfer of information from STM to LTM
Transfer of information from STM to LTM can be promoted by the process of rehearsal, organisation and elaboration of meaning
Rehearsal
Involves repeating a task over and over again, regard as shallow form of encoding information into the LTM
Organisation
Involves organizing information into logical categories, making it more easily transferred from the STM and the LTM
Elaboration
Involves adding meaning of the information to be memorized
