What does semantically similar mean?
Words that have similar meaning. eg.massive,big,huge
What does semantically dissimilar mean?
Words with different meanings. eg. good, tiny, yummy
How did Baddeley investigate STM and what did he find?
He instructed the ppts to recall the list in order immediately. He found that ppts did worse with acoustically similar words
What does this suggest for coding in STM?
STM is coded acoustically
How did Baddeley investigate LTM and what did he find?
Ppts were instructed to recall the list in the correct order after 20 minutes. He found that ppts did worse with semantically similar words
What does this suggest for coding in LTM?
LTM is coded semantically.
