A cognitive psychologist conducted a laboratory experiment to investigate encoding in Short-Term Memory (STM). She used a sample of 32 participants.
Two lists of 10 words were presented to the participants:
All 32 participants studied List A and were asked to perform an immediate recall task. After a suitable break, the same procedure was repeated with List B.
| List A (Acoustically similar) | List B (Acoustically dissimilar) | |
|---|---|---|
| Mean | 4.6 | 7.8 |
| Standard deviation | 1.4 | 1.1 |
Explain what the mean scores in Table 1 suggest about encoding in Short-Term Memory (STM).
