Memory is how we remember things, and it can be pretty complicated. There are three main types we should know about: sensory memory, short-term memory, and long-term memory. Let’s break down the differences in a simple way:

1. How Long They Last:

   • Sensory Memory: This type of memory only lasts for a very short time—just a fraction of a second.
   • Short-term Memory: This one holds onto information a bit longer, usually for about 15 to 30 seconds.
   • Long-term Memory: This is where we store information for a really long time, sometimes even our whole lives!

2. How Much They Can Hold:

   • Sensory Memory: It can take in tons of information, but just for a quick moment.
   • Short-term Memory: This type usually remembers around 7 items (plus or minus 2).
   • Long-term Memory: There’s practically no limit! It’s like a huge backpack that can fit billions of pieces of information.

3. How We Remember:

   • Sensory Memory: This type mostly uses our senses, like what we see and hear.
   • Short-term Memory: Here, we often repeat things out loud to help us remember them.
   • Long-term Memory: This type favors understanding things and making connections, which helps us remember better.

Knowing the differences between these types of memory helps us understand how we think and remember things. It shows us that memory is a big part of how our brains work!
