Understanding the Three Systems of Memory

TLDRMemory consists of three main systems: sensory memory, short-term memory, and long-term memory. Information passes from sensory memory to short-term memory to long-term memory. Sensory memory lasts a few seconds or less, short-term memory lasts a few seconds to a minute, and long-term memory stores facts, experiences, and skills for longer periods. Working memory refers to information actively being processed in short-term storage. Reviewing and rehearsing information in short-term memory can move it into long-term memory. Memory is a complex system that involves multiple storage subsystems and a central executive system to manage the flow of data.

Key insights

📚Sensory memory stores information from the senses for a few seconds or less.

Short-term memory stores information for a few seconds to a minute.

🔒Long-term memory stores facts, experiences, and skills for longer periods.

💡Working memory refers to information actively being processed in short-term storage.

Q&A

What are the three main systems of memory?

The three main systems of memory are sensory memory, short-term memory, and long-term memory.

How long does sensory memory last?

Sensory memory lasts a few seconds or less.

What is the difference between short-term memory and long-term memory?

Short-term memory stores information for a few seconds to a minute, while long-term memory stores facts, experiences, and skills for longer periods.

What is working memory?

Working memory refers to information actively being processed in short-term storage.

How can information move from short-term memory to long-term memory?

Reviewing and rehearsing information in short-term memory can move it into long-term memory.
