One group of participants was asked to recall a list of abstract words, while another group was asked to recall a list of concrete words. The mean number of words correctly recalled for each condition is shown in the table below:
| Condition | Mean Number of Words Recalled |
|---|---|
| Abstract Words | 12.4 |
| Concrete Words | 17.8 |
