multi store model

• Atkinson and Shiffrin (1968) proposed a three-stage model of memory.
• Atkinson & shiffrin used an information processing approach where memory is characterised as a flow of information through a system
• the system is divided into stages that information passes through in a fixed sequence

• sensory register - information from the environment received by sensory stores (iconic store - visual information, echoic store - auditory, haptic store - tactile input). some information is attended and subconsciously processed.
• sensory register - holds information for fractions of a second and has very large capacity
• STM - holds a limited amount of information and only for limited time. Items are usually held as sounds but other methods of encoding are possible. some information is processed further
• LTM - information is transferred from STM is rehearsed. LTM is thought to have unlimited capacity and duration. information is encoded mainly in terms of meaning
• Researchers later suggested there are two types of rehearsal: maintenance rehearsal - acoustically repeating information keeps it in STM. to move information from STM to LTM requires elaborative rehearsal - involves meaning
