Based on the results, taking rest is best for maintaining vigilance. A different perspective can proffer an explanation for this:
Differing tasks which interrupt one during a vigilance task may both utilize distinctly unique resources and require different amounts of resources. The tasks may have elicited different levels of cognitive load.
There exist on-going debate about the origins of vigilance decrement . The best known is based on resource theory. However critics think it is a circular mode of reasoning .
Current findings suggest that vigilance decrement comes from repeated use of executive resources. There may be domain specific interference when the primary task and activities during a break make use of the same resources.
The findings by Ariga do not support the idea that vigilance decrement is due to task under-load.  Knowing why resting can assist with refocusing is difficult. Perhaps, rest allowed participants to engage in day dreaming which eliminated task monotony.
