ATKINSON AND SHIFFRINS MULTI STORE MODEL
135
MEMORY
136
Active information processing system that receives, organises stores and recovers information
137
138
Encoding
139
• Converting information into a useable form of storage
140
Storage
141
• Retaining information over time for future use
142
Retrieval
143
• Accessing previously stored information for use
144
145
Atkinson-Shiffrin multi store model
146
Provides a framework for the process of memory, has three categories
147
Ø Sensory memory
148
Ø Short-Term memory
149
Ø Long-Term memory
150
151
Sensory Memory
152
• Entry point or first stage of memory, info in our environment is received by our senses
153
• Sensory memory has unlimited capacity but only at brief duration, info held in sensory memory has not yet entered awareness
154
• Two examples are iconic memory and echoic memory
155
156
Iconic sensory memory
157
• Visual sensory memory, stores exact copy of all visual information
158
• Lasts for about 0.2-0.4 seconds (e.g. floppy pencil)
159
160
Echoic sensory memory
161
• Refers to auditory (sound) sensory memory & equivalent of visual sensory memory
162
• Echoic memory is retained for 3-4 seconds and stores and exact copy of all auditory information
163
164
Short Term Memory
165
Store of memory which holds information that is consciously being attended to and actively manipulated
166
167
• Duration of short term memory is 12-30 seconds
168
• Capacity of short term memory is 5-9 items
169
170
Rehearsal and chunking
171
Chunking: Process by which you can group 'chunks' of info into larger 'chunks' in order to hold more info in STM
172
Maintenance rehearsal; involves repeating new information over and over again to keep the information in the STM for as long as possible
173
174
Long Term Memory
175
LTM is relatively permanent memory system that holds vast amounts of information for a long period of time, possibly indefinitely
176
• For something to move from STM to LTM it must be encoded, if this does not occur the memory will be displaced
177
178
How it works
179
Ø Unlimited duration
180
Ø Unlimited capacity
