Question 282

Auditory Ergonomics and Cognitive Load

An ergonomic researcher investigated the effect of auditory masking on cognitive performance using a repeated measures design.

  • Condition 1: Participants completed a high-difficulty programming task while listening to a naturalistic biophilic soundscape (simulated rain and wind). The researcher measured the time taken to find bugs in a script.
  • Condition 2: The same participants completed a high-difficulty programming task of equivalent complexity while listening to a continuous synthetic pink noise mask. The researcher measured the time taken to find bugs in a script.

In experiments using repeated measures designs, researchers often use counterbalancing.

Explain how the researcher might have used counterbalancing in this study.
