Short and Long Term Memory Flashcards
What is coding and what types of coding are there?
Coding is the way in which information is changed so that it can be stored in memory after entering through the senses.
- Visual (pictures)
- Acoustic (sounds)
- Semantic (meaning of experience)
What is duration?

What is long term memory? What is the coding, duration and capacity?
Long-term memory is for that have happened in the past.

Coding- mainly semantically
What is short term memory? What is the capacity, duration and coding?

Coding - acoustically
What is capacity?
