1. Short-term memory is viewed as a
rapidly decaying system. Most psychologists believe that short-term
memory does not involve permanent changes in the brain. However, some
temporary changes occur in this case. The physiological nature of the
traces is such that they fade quickly. The long-term memory appears to
be permanent. A permanent change occurs in our brain when we remember
things for a longtime. Long-term memory has a more or less enduring
impression on the brain. Because of the consolidation of traces, the
traces are relatively permanent.
2. Short-term memory has limited storage
capacity resistant to overcrowding in any form. It just cannot take any
overload. On the other hand, long-term memory is limitless for all
practical purposes. Any information transferred from short-term memory
to long-term memory will have a place for permanent storage.
3. Short-term memory is an active system
involving rehearsal. We need to keep the items actively in STM
relearning them constantly. On the other hand, the long-term memory is
rather passive in nature; it is not easily disturbed by interruption,
unlike short-term memory.
