A cognitive psychologist investigated coding in short-term memory using a repeated measures design.
To ensure short-term memory was tested, participants were asked to recall the words immediately after presentation.
Table 1: Mean number of words recalled and standard deviations after immediate recall
| Words that sounded different (acoustically dissimilar) | Words that sounded similar (acoustically similar) | |
|---|---|---|
| Mean | 8.4 | 4.6 |
| Standard deviation | 1.3 | 0.8 |
What do the mean values in Table 1 suggest about coding in short-term memory? Justify your answer.
