Continuous Partial Attention – Life of Pipeline Controller

Posted May 18th, 2009

“When we constantly monitor everything while never focusing on anything” is a description of continuous partial attention. Linda Stone, a software executive, is quoted in the book iBrain. I read about the concept somewhere else.  If one reads some job descriptions for pipeline controllers, one will see these phrases:

• Maintain a high level of attention for extended periods of time
• Flawless operation of SCADA system
• Ability to remain focused under highly stressful situations

How does a controller do those things if the concept of continuous partial attention applies in control rooms?  I believe it does apply because control room operators must continuously monitor everything on the display screens.

What is the effect on our brains, and on our performance?  Because we are waiting on an event, planned or unplanned, our brains are stressed.  If an unplanned event(alarm, phone call) occurs at the same time as a planned event, the person has to address the one with the highest priority while still paying attention to the other event.  He or she also has to monitor the rest of the system.

Continuous Partial Attention:  Could it be the precursor to an error or accident?
