memory
the retention and retrieval of information or experience over time
3 processes of memory
1: encoding
2: storage
3: retrieval
encoding
information gets into memory
depth of processing
levels of processing
-level of memory processing
- shallow, intermediate, deep
- deeper processing producing better memory
shallow processing
intermediate processing
giving stimulus a label
- as in reading the word mom
deep processing
thinking about the meaning of a stimulus
- thinking about the meaning of the word mom and about your own mother
elaboration
(deep processing)
formation of a number of different connections around the stimulus at any given level of memory
self-reference
relating material to your own experience
- helps to elaborate deeply on information
- drawing links to your own life
hippocampus activated:
when individuals are using elaboration during encoding
mental imagery
Paivio’s argument
memory is stored in one of two ways: verbal code (word or label) or image code
dual code hypothesis
(Paivio)
memory for pictures is better than memory for words and pictures
- pictures are stores in both image codes and verbal codes
storage
encompasses how information is retained overtime and how it is represented in memory
Atkinson-Shiffrin theory
memory storage involved 3 separate systems
1: sensory memory: time frames of a second to several seconds
2: short-term memory: time frames up to 30 seconds
3: long-term memory: time frames up to a lifetime
sensory memory
holds information from the world in its original sensory form for only an instant
echoic memory
(echo)
auditory sensory memory
iconic memory
(icon = image)
retained for about one-quarter of a second
short-term memory
individuals are limited in how much information they can keep without external aids
range of 7 +- 2
chunking
grouping or “packing” information into higher-order units
- can be remembered as single units
working memory
combination of components
3 part model of working memory
