Structure and process of memory

Question 1

Describe the structure and the process of memory?

Answer 1

• Information is input via our senses
• The brain processes the information received from our senses
• Brain stores the information by encoding the input into a memory trace which can be stored/used by the brain
• Memory system holds the information for a few seconds or for an entire lifetime
• Output/retrieval of memories is by a behavioral response in humans

Question 2

How is data stored in the short term memory (STM) ?

Answer 2

• Data enters the short term memory store, (a temporary store that lasts for 18 seconds and holds seven items of information.)
• STM encodes information acoustically through repetiton. By rehearsing the information, it can be stored in the STM for many minutes.

Question 3

Duration and capacity of the LTM store?

Answer 3

• LTM can last for minutes or up to an entire lifetime
• Holds unlimited amout of information
• Encoding in the LTM is mainly semantic but can also be visual and acoustic
