Memory is the process involved in retaining, retrieving, and using information about stimuli, images, events, ideas and skills after the original information is no longer present. It is important for dealing with day-to-day events, and cases such as clive wearing"s illustrate the important of memory in normal functioning: sensory memory = fraction of a second. Atkinson & shiffron"s modal model of memory consists of 3 structural features sensory memory, stm, and ltm. Another feature of the model is control processes such as rehearsal and attentional strategies: e. g. Sparkler light being moved = perception of a trail of light. The duration of visual sensory memory (iconic memory) is less than 1 second, and of auditory sensory memory (echoic memory) is about 2-4 seconds: shot term memory (stm) - 5-7 items, for 15-20 seconds.
