A cognitive psychologist conducted a study to investigate if playing low-fi background music whilst reading a complex text affects comprehension recall performance. An independent measures design was used, testing a small group of 12 students. Half of the participants read the text in silence, whilst the other half listened to low-fi background music. The data representing recall scores (out of a maximum of 15 points) is shown in the table below.
| Recall score (max 15) when reading under different auditory conditions | |||
|---|---|---|---|
| Background Music | Silence | ||
| Participant | Score | Participant | Score |
| 1 | 12 | 1 | 11 |
| 2 | 11 | 2 | 7 |
| 3 | 13 | 3 | 14 |
| 4 | 9 | 4 | 6 |
| 5 | 14 | 5 | 10 |
| 6 | 11 | 6 | 8 |
