Memory Flashcards
What are the 3 stages of memory
> Encoding
Storage
Retrieval
What are the 3 types of storage’s?
> Sensory
Short term
Long term
What are the 3 parts to long term memory
> Episodic
Semantic
Procedural
What part of memory is damaged in dementia?
> Short term
What is superior memory?
> Recency effect
>Remember words later in a list
What is enhance memory?
> Primary effect
>Remember words earlier in a list
Describe echoic memory
> Recency persists
>Sound lingers> persists for loner
Describe Iconic memory
> No recency effects
>Images fades quickly
What is the capacity of short term memory?
> 7 +/- 2 digits
What is chunking?
> Memory method
>Organise info into larger meaningful units
What happens when you count backwards?
Lose info by displacement
>Lose recency effect
>Lose superior memory for words later in list, gain for those earlier
>Short term memory replaced by numbers you have to keep in your head while reading backwards
What does rehearsal do?
> Improves primacy
Maintains maintenance
Maintains & elaborates> linked to long term
What is episodic
> events related to you
What is semantic?
> General knowledge
What is procedural?
> Skills based
Methods for encoding in long term memory
> Meaningful connections
Elaboration
Mnemonics
What is Synaesthesia?
> Crossing of sensory modalities> multiple percepts
What is the Luria’s caste study (Synaesthesia)
Edetic imagery >Memory and visual percepts Method of loci >Journey method >Told & visualised story to help memorise
What is Hyperthymia
> Highly superior autobiographical memory HSAM
> Irrepressible stream of memories impairs cognitive performance
Retrieval from LTM
> Recall vs recognition
Context effects

Give me 2 examples of short term memory
> Echoic
>Iconic
Who came up with the multi-store memory model?
Baddeley
look at diagram in notes
What is the serial position curve
> Position of word in list influences ease of recall
What are the 2 alternative descriptions of memory systems
> Explicit (knowing that)
>Implicit (knowing how)
Process of explicit memory
>The cognitive system >Explicit >Working memory PFC >Consolidation Hippocampus >Long term memory TOP >Episodic/ semantic
Process of implicit memory
> Implicit
Basal ganglia/ cerebellum
Skills/ classical conditioning
