Which measure of memory retention assesses?
Speed of relearning is one measure of memory retention (From Baddeley, 1982). Tests of recognition and of time spent relearning demonstrate that we remember more than we can recall.

It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
How is memory encoded?
Encoding is achieved using chemicals and electric impulses within the brain. Neural pathways, or connections between neurons (brain cells), are actually formed or strengthened through a process called long-term potentiation, which alters the flow of information within the brain.

What is the duration of echoic memory?
When your ears hear a sound, they transmit it to the brain where echoic memory stores it for about 4 minutes. In that short time, the mind makes and stores a record of that sound so that you can recall it after the actual sound has stopped. This process is ongoing, whether you are aware of the sounds or not.
