Memory Flashcards
What is confabulation?
The invention of plausible and detailed false memories in response about personal life and public events to fill in memory gaps.
What is memory?
The process by which we take something we have observed (encountered) and convert it into a form we can store, retrieve and use.
What are the processes of memory?
- Encoding
- Storage
- Retrieval
What are representational modes?
They are like languages that permit conversation with the mind.
What is a mental representation?
A mental model of a stimulus or category of stimuli,
- Sensory representations
- Verbal representations
- Motoric representations
What is a sensory register?
Hold information about a perceived stimulus for a fraction of a second after the stimulus disappears.
What are two types of sensory register?
- Iconic storage
2. Echoic storage
What is Iconic storage?
Momentary storage of visual information
What is Echoic storage?
Momentary storage of auditory information.
What is Short-term memory?
Holds a small amount of information (limited capacity of approximately 7 items) for a short period of time (limited duration of approximately 20-30 seconds).
How can you keep information in STM longer?
Rehearsal / Elaborative rehearsal (Thinking about the information whilst rehearsing.
What is Long-term memory?
The representations of facts, images, actions and skills that may persist over a lifetime (potentially limitless duration).
What is the process of extracting information from the LTM?
Retrieval.
What is the best way to keep information in the LTM?
Keep it in the STM for as long as possible.
What is the Serial Position Effect?
The tendency to remember information at the beginning and end of a list rather than in the middle.
What are ways in which thinking about memory has no evolved?
- No longer a serial processing model.
- Memory is now thought of to be a number of modules which are discreet but interdependent.
- Remembering is not always conscious and retroactive.
- Not thought of as a computer.
- LTM must engage before STM.
What is working memory?
The temporary storage and processing of information.
What is working memory used to do?
- Solve problems
- Respond to environmental demands
- Achieve goals.
Working memory is comprised of what three memory systems?
- Central executive (flow and processing of information)
- Visual memory store (visual sketchpad)
- Verbal memory store (phonological loop).
What are two separate aspects of working memory?
- Storage capacity
2. Processing capacity.
What neural region is thought to control working memory?
The prefrontal cortex
What is a LTM deficit?
Person shows normal working memory though cannot transfer information to LTM
What is working memory deficit?.
Person has a memory span of 2 digits though normal LTM.
How should working memory be viewed?
As a conscious workspace for accomplishing goals rather than a way station or gateway to LTM.
