Question 361

Scenario

Psychologists designed an experiment to test the effects of fast-tempo background music on concentration and focus. They recruited a sample of 40 university students and asked them to complete two proofreading tasks. Both tasks involved reading a 300-word academic text and finding as many grammatical errors as possible within a 3-minute time limit.

Each participant completed both tasks:

  • Task A: completed whilst listening to fast-tempo instrumental synthwave music through headphones.
  • Task B: completed in silence, with no auditory distractions.

The order in which they completed the tasks was counterbalanced.

Question

Identify one potential extraneous variable in this experiment. Explain how this variable might have influenced the results of the study.
