Distraction: Definition and Examples
What is a Distraction?
Distractions take attention away from what an operator needs to do when performing a task. Distractions can be external (such as noise) or internal (such as fatigue, rumination, or stress).
Distractions may be caused by a number of factors, including the loss of interest in the primary activity, inability to pay attention due to various reasons, or intensity of the distractor.
