Multi-store model

• Sensory Memory Environmental stimuli are captured by sensory memory (SM). This first memory store may be sub-divided into - the iconic (ie visual, captured through the eyes) - echoic (auditory, captured through the ears) memory. - duration less than half a second - high capacity, for example over one hundred million cells in one eye. Information is only transferred to STM if it is paid attention to.
• Short Term Memory (STM). Information is held for immediate tasks - Limited duration (a matter of seconds) - Limited storage capacity. - Information will disappear if new information enters (displacement)
• Long Term Memory (LTM) Some memories are transferred to the LTM through a process of elaborative rehearsal. - Unlimited capacity - Unlimited duration
• Retrieval When required, memories can be recalled from the LTM and brought into the STM where they can be accessed by a process called retrieval.
• Maintenance rehearsal – retaining information in ST for as long as it is required (seconds)
• Elaborative rehearsal – transferring memories into LT via deep learning
