Memory and Encoding By Farid and Kim
Memory processes Encoding: Transforming sensory information into a meaningful memory. Storage: Creating a biological trace of the encoded information in memory, which is either consolidated or lost. Retrieval: Using the stored information
Encoding types of Memory
Imagery Memory Taken from brief sensual interference with the environment Through visual or auditory interaction Baddeley and Hitch (1974) – “Visuospatial scratchpad”
Procedural Memory Memory for knowing how to do things Walk, talk, eat Unable to consciously describe how we do them Highly resistant to forgetting
Declarative Memory Concerns all the information that we can describe or report Semantic memory: general facts and knowledge Eg. Knowing that Obama is president Episodic: “knowing when” memory Eg. Through association Lindsay and Norman (1977) – based upon personal experience
Duration types of Memory
Sensory Memory Comes from senses and has a limited capacity of less than a second It could be iconic memory or echoic memory Sperling – Iconic Memory
Short-Term Memory Information selected by attention from sensory memory, may pass into short-term memory (STM) Allows us to remember long enough to use Lasts between 15-30 seconds and has a limited capacity of 7 (+/- 2) chunks of information Mostly encoded acoustically Peterson and Peterson (1959)
Long-Term Memory Ranges between minutes and a lifetime Although the capacity cannot be measured, it is almost limitless Mainly encoded through the meaning (semantic memory), also retains procedural skills and imagery Baddeley (1966) – Semantic memory
