What is the difference between working memory and long-term memory?
Instead, working memory involves the process of active maintenance of a limited amount of information. Long-term memory is also needed to support performance as soon as attention is diverted, even when the amount of material to be learned is limited and even when it is amenable to rehearsal.
What is the capacity and duration of long-term memory?
Theoretically, the capacity of long-term memory could be unlimited, the main constraint on recall being accessibility rather than availability. Duration might be a few minutes or a lifetime. Suggested encoding modes are semantic (meaning) and visual (pictorial) in the main but can be acoustic also.
What is the difference between long-term memory and short-term memory?
While long-term memory has a seemingly unlimited capacity that lasts years, short-term memory is relatively brief and limited. Since short-term memory is limited in both capacity and duration, the retention of memories requires transferring the information from short-term stores into long-term memory.
What are the duration and capacity of short-term and long-term memory?
Short-term memories last only for about 18-30 seconds while long-term memories may last for months or years, or even decades. The capacity of long-term memory is unlimited in contrast to short-term and working memory.
