Today we will be reviewing the concept of memory.
00:06
There are three different types of memory.
00:10
The first one is sensory memory.
00:12
It's very brief.
00:14
We keep that information in the original sensory form.
00:18
Usually we think about it in terms of visual or auditory information, and we keep it in our memory, in our sensory memory, for less than one second.
00:29
The second type of memory is short -term memory, or some people call it working memory.
00:38
And this is also very limited, but we can keep it for a little bit longer than our sensory memory.
00:45
We can remember information in short -term memory for approximately 20 seconds.
00:52
We can keep information in our short -term memory by rehearsing it to ourselves and just repeating it to ourselves.
01:01
That's why people also referred to short -term memory as working memory...
