(7.1) Memory Systems
Memory: Collection of several systems that store information in different forms for different
amounts of time
The Atkinson-Shiffrin Model
Stores Retain information in memory without using it for any specific purpose
(Sensory Memory -> Short-Term Memory -> Long-Term Memory)
Control Processes Shift information from one memory store to another
o Information enters sensory memory through vision, hearing, and other senses
then CP selects which info to pass onto STM
Encoding Process of storing information in the LTM system
Retrieval Brings information from LTM back into STM
Sensory Memory: Memory store that accurately holds perceptual info for very brief amount of
time
1. Iconic memory: Visual form for ½ - 1s
Two conditions (Whole report and partial report)
Could hold 12 letters as mental image
2. Echoic memory: Auditory form for 5s
Short-Term Memory (STM): Memory store with limited capacity and duration (<min)
Long-Term Memory (LTM): Memory store that holds information for extended periods of time,
if not permanently
The Serial Position Effect: Memory for order of events is often better for first few items
(primacy effect) and last few items (recency effect)
Proactive Interference: First information learned occupies memory, leaving fewer resources
left to remember the newer information
Retroactive Interference: Most recently learned information overshadows some older
memories that have no yet made it into LTM
The Working Memory Model: An Active STM System
Working memory:
Model of short-term remembering that includes a combination of memory components
that can temporarily store small amounts of information for short period of time
1. Phonological Loop: Storage component of working memory that relies on
rehearsal and stores information as sounds or auditory code
2. Visuospatial Sketchpad: Storage component of working memory that maintains
visual images and spatial layouts in a visuospatial code
3. Episodic Buffer: Storage component of working memory that combines the
images and sounds from the other two components into coherent, story-like
episodes
