Short Term & Working Memory

Question 1

Chunking (recoding)

Answer 1

Grouping small units into larger, more meaningful units that can be single items and easier to recall

Question 2

Brown-Peterson Paradigm

Answer 2

Subject given 3 constants; asked to count backwards by 3s from random number; then asked to recall after delay.

-shows effects of proactive interference

Question 3

Theories of forgetting

Answer 3

Decay hypothesis and interference hypothesis

Question 4

What is the primary source of forgetting in STM?

Answer 4

Proactive interference

Question 5

Proactive Interference

Answer 5

Old learning interferes with new learning

Question 6

Retroactive interference

Answer 6

New learning interferes with remembering things from old learning
