Chapter 6 - Models For Human Memory Flashcards
Encoding
Encoding is the process of converting information into a useable form so that it can be represented and stored in memory.
Memory
Defined as the processing, storage, and retrieval of information acquired through learning.
Storage
Storage is the retention of information in memory over time.
Retrieval
Retrieval is the process of locating and recovering the stored information from memory so that we are consciously aware of it.
Atkinson and Shiffrin’s multi-store memory
Memory consisting of 3 separate components: sensory register, short term store and the long term store.
Control processes (Atkin)
in the Atkinson–Shiffrin multi- store model, an activity that is consciously performed to assist the memory process, such as attention and maintenance rehearsal
Sensory Memory
Entry point of memory where new information is stored for a very brief period. Info received by each sensory system is retained as an exact copy of its original “RAW” sensory form.
Ionic memory
- visual memory
- images are held in retina for 0.2-0.3 seconds
- unlimited capacity
- allows fluid vision of moving subjects
Echoic memory
- registers and retains all kinds of sound
- duration of 3-4 seconds
- unlimited capacity
Short term Memory (STM)
- limited capacity 7+-2 items
- limited duration: 18-25 seconds
- contains everything that you are consciously aware of at any moment and paying attention to.

MAINTENANCE REHEARSAL
Elaborative rehearsal
- linking new information to old information in LTM
- meaningfully linking together two or more pieces of new info
- linking new info to real life (everyday examples)
Maintenance rehearsal
Involves repeating the information being remembered over and over again so that it can be retained in STM or Working memory.
Working memory
Emphasises the part of memory where information is temporarily held and actively “worked on” as we undertake our everyday tasks.
