A researcher investigated coding in long-term memory using a repeated measures design.
To ensure long-term memory was tested, participants performed a 20-minute distractor task before being asked to recall the words.
Table 1: Mean number of words recalled and standard deviations after a 20-minute delay
| Words with different meanings (semantically dissimilar) | Words with similar meanings (semantically similar) | |
|---|---|---|
| Mean | 11.4 | 6.8 |
| Standard deviation | 2.3 | 1.1 |
What do the mean values in Table 1 suggest about coding in long-term memory? Justify your answer.
