Encoding Flashcards
Name three types of encoding.
Visual, acoustic and semantic
What is encoding?
HOW information is stored in the brain
How is information encoded in short-term memory?
Visual / acoustic
How is information encoded in long-term memory?
Semantically
What did Baddeley want to investigate?
How encoding differs between STM and LTM
What did Baddeley test?
The effect of acoustic and semantic similarity of words on short and long term recall
What 4 groups did Baddeley use?
- Acoustically similar
- Acoustically dissimilar
- Semantically similar
- Semantically dissimilar
How many words did Baddeley’s participants have to recall?
12 sets of 5 words
How did Baddeley’s participants have to recall the words?
In the correct order
What did Baddeley find for STM?
Poorer recall for acoustically similar words
What did Baddeley find for LTM?
Poorer recall for semantically similar words
How does Brandimote et al. (1992) challenge Baddeley?
Found STM used visual encoding - if given a visual task and prevented any verbal rehearsal
How does Wickens et al. (1976) challenge Baddeley?
Found STM used semantic encoding
How does Frost (1972) challenge Baddeley?
Found LTM used used visual and semantic encoding
How does Nelson and Rothbart (1972) challenge Baddeley?
Found LTM used acoustic encoding
