7.1 - memory systems
Cards in this deck (28)
- 1StoresRetaining info in memory without using it for a specific purpose
- 2Control processesShift info from one memory to another
- info from senses enter sensory memory --> control processes of attn select which info passes onto STM - 3Encoding- process of storing info in LTM
- transform sensory/perceptual info into memory traces - 4Retrieval- Bring info from LTM back to STM
- Accessing memorized info and returning it to STM - 5Sensory memoryMemory store that holds perceptual info for a brief time
- 6STMmemory store with limited capacity and duration
- 7Chunkingorganizing smaller units of info into larger more meaningful units
- experience/expertise plays role
- STM - 8LTMmemory store that holds info for extended periods of time, permanently
- 9Serial position effectPeople tend to remember the first few and last few words from a list, and only 1 or 2 in between
- 10Primacy effectRemember first few words bc already in LTM
- 11Recency effectRemember last few words bc still in STM
- 12Proactive interferenceThe first info learned occupies memory, leaves fewer resources to learn newer info
- 13(Serial) retroactive interferenceMore recent info overshadows older memories that haven't made it into LTM yet
- 14RehearsalRepeating info until don't need to remember anymore
- 15Working memorySTM that includes memory components that temp store info for short periods of time
- 16Working memory - 4 components- episodic buffer
- phonological loop
- visuospatial sketchpad
- central executive - 17Phonological loop- Relies on rehearsal
- Stires info as sounds/auditory code - 18Visuospatial sketchpad- maintains visual images, spatial layouts in visuospatial code
- 19Episodic bufferCombines images of PL and VS into coherent episodes
- 20Central executiveCoordinates attention and exchange of info bw EB, VS, PL
- seeks out what is relevant to goals, interests, prior knowledge - 21Feature binding- chunking in visuospatial memory
- items stored in visuospatial memory can be counted based on shapes, colours, textures
- can retain 4 whole objects regardless of # of features on those objects - 22LTM - 3 components- declarative (explicit)
- nondeclarative (implicit)
- procedural - 232 types of declarative memory- episodic = personal experiences
- semantic = facts - 24Long term potentiationincrease in connectivity and TM or neural signal bw nerve cells that fire together
- 25Consolidationconverting STM into LTM
- when LTP continues long and often enough, neurons adapt and make the changes more permanent - 26Amnesiaprofound loss of at least one form of memory
- 27Retrograde amnesiamemory for events preceding trauma/injury = lost
- 28Anterograde amnesiainability to form new memories for events occurring after brain injury
