Intensive Meditation Training Increases the Ability to Sustain Attention

Vigilance tasks require an observer to note when a target occurs. Much research has been done in this area due to important military and security applications. For example, an observer might need to detect enemy planes approaching on the radar scope. Or it might be security personnel monitoring baggage at an airport. Moreover, there is need to distinguish dangerous from benign targets on the scope. Although this is obviously a very important task, it would also appear to be a very simple task. The problem is that over prolonged periods of time performance drops off. In spite of all the research that has been done, techniques for sustaining attention have been found lacking. A recent article1 presented research that found that intensive meditation training can aid sustained attention. Other research2 has found that vigilance requires hard mental work and is stressful. Research using questionnaires and measurements of cerebral blood flow velocity have documented that vigilance is stressful and hard mental work. Attentional resource theory has been used to account for the vigilance decrement. The notion is that attentional resources are rapidly depleted by the demands of the vigilance task.

The meditation training used in the first article was quite intensive. It involved going to a retreat. Shamantha3 meditation training was used in at least five three day retreats. The meditation training was found to sustain vigilance for a longer time, presumably by increasing attentional resources.

You might ask, so what? My job does not involve vigilance tasks. The relevance to you is that meditation apparently does increase attentional resources. Meditation training has been found to be beneficial to temporal attention, attentional alerting, and visual discrimination. Moreover, readers of the Healthymemory Blog should be well aware of the critical role of attention in cognitive performance, and that many failures and breakdowns in cognitive processing are due to limited attentional resources.
