Psychology- memory

• The multi-star model of memory was proposed by Richard Atkinson and Richard Schiffrin in 1968 to explain how information from the environment can make it into our long-term memory.
• The multi-star model proposes that there are multiple or separate stores for three types of memory: sensory, short-term, and long-term.
• Sensory memory and short-term memory are thought to be unitary stores, forming a single unit or store.
• According to the multi-star model, information from the environment is received by the sensory register, which is then passed to short-term memory when attention is paid to it.
• Information in short-term memory can be rehearsed, which allows it to be temporarily kept in memory for a short period of time, a process known as maintenance rehearsal.
• For information to go from short-term memory to long-term memory, it needs prolonged rehearsal.
• The multi-star model is an example of a linear model, with the processing of the memory happening sequentially in a series of stages going from one store to the next.
• Theoretical models like the multi-star model allow psychologists to provide testable theories about mental processes which can then be studied scientifically.
• The multi-star model has been extensively researched to test its accuracy in explaining memory.
• The sensory register encodes information according to the sense or mode in which it is received, which is modality specific.
• The length of time that sensory memories last varies slightly depending on the format in which it is coded, with iconic memories thought to last around 250 milliseconds or a quarter of a second.
• The length of time that sensory memories last for varies slightly depending on the format in which it is coded, with iconic memories thought to last around 250 milliseconds or a quarter of a second.
• The length of time that sensory memories
• Capacity is the amount of information that the store can hold.
• Sensory memories have a very short duration and fade away very quickly.
• The length of time the memory lasts for or how long it is kept in the store before it's forgotten is referred to as duration.
