Answer:
According to the model of memory proposed by Atkinson and Shiffrin, the Short Term Memory is a memory system that can hold about seven items for about 30 seconds.
Step-by-step explanation:
The Atkinson and Shiffrin model is a theory of human memory, proposed by Richard Atkinson and Richard Shiffrin in 1968. It explains that short-term memory is related to information memories that are absorbed by our senses over time enough to be used. The study showed that Short-Term Memory lasts less than 30 seconds unless attention is paid to the information within that time. Miller's 1956 study explained that seven (plus or minus two) pieces of information can be learned in that 30-second period.
