Module 8: Memory Flashcards
Memory
storage and retrieval of information
Search metaphor
A way of describing processes involved in memory using terms and phrases that relate them to around in physical or virtual space
Failure of search
The way that an inability to remember something is often described
Reconstruction metaphor
describes how we primarily use memory to formulate a useful response using both what we known and the surrounding situation
Encoding
The process of how information is initially learned
Encoding problem
The problem the brain must solve to transform an experience into a memory
storage
The process of maintaining information about an event over time weather short or long
Storage problem
The problem the brain must solve to maintain information in the brain over time short or long
Sensory memory
The system that keeps information translated by the senses briefly in unaltered form, allowing us to perceive the world as whole rather than staggered
iconic memory
fleeting after images in visual system
echoic memory
echoes that last a few seconds after auditory signals… sometimes allowing you to recall end of conversation you were not paying attention too
immediate memory
A system that actively holds on to a limited amount of information so that it can be manipulated and processed
3 properties of immediate memory
representation, duration, and capacity
representation
The kind of information a memory system contains. often this described in terms of how the information is represented of coded
inner voice
The mental experience of hearing yourself talk in your head - evidence for verbal representation in immediate memory
inner eye
The mental experience of seeing something using your imagination - evidence for visual representation in immediate memory
Rehearsal
The process of repeating information to yourself, helping you rehear the information over again
Duration
How long a memory system can contain information before its forgotten, duration is indefinite with rehearsal but without rehearsal is only three seconds or so
Capacity
How much information can be held in a memory system at any one time, capacity is consider to whatever you can rehearse in around 2 seconds
Range of information a person can hold in mind at any given time
7 plus/minus 2 (5-9)
memory span
The number of items that can be kept active in immediate memory at one time
Chunking
process of arranging information into compact meaningful chunks so that they can be more easily rehearsed in immediate memory
Working memory model
A model of immediate memory that emphasizes its role as a system for manipulating information in consciousness
phonological loop
A system within the working memory model that temporarily stores and manipulates auditory and verbal information
visuospatial sketchpad
A system within the working memory model where visual and spatial information is stored and manipulated
Central Executive
Hypothetical portion of the working memory that directs the activities of working memory and flow of information between working and long term memory
Long term memory
Memory system used to store and recall information over extended periods of time (indefinite split into subsections)
