Psychology Module 2 Flashcards
What does input mean in regards to human memory?
The sensory information received from our environment
What does encoding mean?
Turning input into memory that can be used by the brain
What are the three most common types of encoding?
- Visual encoding (sight)
- Acoustic encoding (hearing)
- Semantic encoding (meaning)
What does output mean in regards to human memory?
The information recalled/retrieved, i.e behavioural response
What is the duration and capacity of short term memory?
Duration: 18 seconds
Capacity: 7 items
What is the duration and capacity of long term memory?
Duration: Few minutes - entire lifetime
Capacity: Potentially limitless
What is rehearsal?
When information is repeated - a method to transfer short term memory to long long term memory
How are short term memories forgotten?
- Displacement (when capacity is exceeded old memories are pushed out)
- Decay (memory trace unused)
How are long term memories forgotten?
- Decay
- Interference (old info overwritten by new info)
- Retrieval failure (memory still there, unable to be recalled)
What is retrograde amnesia?
A memory condition that damages the ability to recall long term memories prior to brain damage
What is anterograde amnesia?
A memory condition that damages the ability to form new long term memories (memories before incident undamaged)
What is Bartlett’s Theory of Reconstruction?
Memories are interpretations of events based on schemas, which is why details are changed/omitted upon recall
What is Atkinson and Shiffrin’s Multi-Store Model of Memory?
Memory is split into long-term, short-term, and the sensory register, and can be retained for longer through rehearsal
What was the procedure of Barlett’s War of the Ghosts study?
Participants asked to read War of the Ghosts story, then later retell it. Some through serial reproduction (retell verbally) other through repeated reproduction (recall story and write it).
What were the results of Barlett’s War of the Ghosts study?
- Basic outline of story remained
- Rationalisation (added details to make sense of information)
- Omission (unpleasant/unfamiliar details left out)
