memory Flashcards
memory
the ability to encode, store and retrieve information, this includes past experiences, knowledge and thoughts
sensory memory
retains all visual and auditory input but only for 1-2 seconds. only selected information is encoded into the short term memory
short term memory
has a limited storage space of 7 items. can hold these pieces of information for around 30 seconds, this is known as memory span. can be extended by chunking and rehearsal
chunking
grouping pieces of information together
rehearsal
involves repeating the information over and over. this helps encode into the long term memory but this is a shallow method
long term memory
has an unlimited storage space
organisation
deep form of encoding, involves putting the information into logical categories
elaboration
deep form of encoding, involves associating the information with meaning or linking it with a previous memory
working memory
allows us to process information from the short term memory and helps us carry out simple cognitive tasks such as counting
memory loss from the short term memory
displacement is the loss of information as new information enters
decay is the breakdown of the memory trace
serial position effect
when an individual is given a list of items they will be able to recall the first few items due to rehearsal and the last few items due to recency. they will not be able to recall the middle few items due to displacement
retrieval
the ability to recall a memory. this can be done as memories are stored in logical categories. contextual cues can also aid retrieval
