A cognitive psychologist investigated the capacity of the phonological loop using a word recall task. Participants were presented with lists of 25 phonologically similar words and asked to recall as many as possible. The distribution of recall scores for the sample of 120 participants is shown in Table 2 below.
| Number of words correctly recalled (out of 25) | Frequency |
|---|---|
| 1 – 5 words | 15 |
| 6 – 10 words | 25 |
| 11 – 15 words | 40 |
| 16 – 20 words | 30 |
| 21 – 25 words | 10 |
