However if memories aren’t accessed then we can lose them, which is called decay.Īttention: Taking notice of an event or information. Information can be retrieved from the LTM so we are able to recall things from the past. Long term memories are believed to be mainly semantic memories- those with meanings.
Your long term memory can hold information for up to a lifetime (duration) and has a limitless capacity. If the information is rehearsed for long enough then it gets transferred into our LTM. If we rehearse the information we are able to store it for longer. If we have too much information in the short term store the older information is pushed out (displaced). Here it can be stored for between 18-30 seconds (this is known as the duration of STM). Information that we pay attention to gets transferred to our short term memory (STM). However, you don’t pay attention to all of it, just the person talking to you. We do not pay attention to all of the information around us.įor example, if you’re at a party you register noise around you such as people talking and the music playing.
If you think about all of the sensory information around you in your environment (everything you see, touch, taste, hear, smell) you can understand that we register a lot of information briefly. They looked at the findings from memory experiments conducted by other researchers and were able to identify 3 different stores in our memory system: The sensory register, Short term memory and Long term memory. Richard Atkinson and Richard Shiffrin developed the multi-store model of memory in 1968. behavioural response Theories of Memory Multi Store Model of Memory (MSM) Semantic Encoding: Storing meaningful information Visual Encoding: Storing visual information Input: Sensory information in the environmentĮncoding: Turning sensory information in to a form that can be storedĪcoustic Encoding: Storing sounds in memory
