A term that is new, yet widely used today: Multi-Tasking.  Hmmph.  It didn’t even exist when I was in college.  Well, maybe it did – in a laboratory somewhere.  But you would never have heard it in conversation intermixed with discussions of Jefferson Airplane, Haight-Ashbury, and the like.  We were waaaaaay too busy not trusting anyone over thirty.

This term: Multi-Tasking got its birth in a computer lab.  Here is a short history lesson.   In prehistoric times (like the 70’s), computers could only do one task at a time.   The inventor of Windows was in kindergarten.  There was no task bar, no icons and no mouse.  Egads!  No mouse??!

Monitors displayed only text and that was often green or orange letters on a black background.  (I can hear you shrieking, now)  One program at a time.  My college roommate majored in computer sciences.  He would encrypt his program on IBM cards. He would then make an appointment to get the program tested at the computer center at 3:00AM – because it was the only time available.  Computers – even very large ones – only ran one program at a time.

As the technology became more sophisticated users demanded more than the one-program-at-a-time approach.  Voila!  We have the invention of Multi-Tasking.

Sorry to say: computer processors could still only do one thing at a time.  That remains true to this very day.   We’ve been hoodwinked; bilked, as it were.  Hold on a minute … before you return your brand new techno-gear … here’s the rest of the story.


 Software coders started lacing programs with “interrupts.”  Allow me to be a little technical. For example: the processor is doing one thing, i.e. running Microsoft Outlook.  The programmers built interrupts into Outlook telling the processor, “you can pause working for me at this spot in order to check and see if anyone else wants something.”

The processor quickly switches to something else, if needed, and when it hits an interrupt in that program, it switches back to Outlook.  We humans get fooled.  We think the computer is doing two things at once because it is happening so fast.  Uh-uh.

So, how does this term Multi-Tasking affect humans?  The result of clinical research shows this:

Because the brain cannot fully focus when multitasking, people take longer to complete tasks and are predisposed to error. When people attempt to complete many tasks at one time, “or alternate rapidly between them, errors go way up and it takes far longer—often double the time or more—to get the jobs done than if they were done sequentially,” states Meyer. This is largely because “the brain is compelled to restart and refocus.”

Multi-Tasking hits CONCENTRATION



I know.  Cops are expected to: drive safely, stay aware of bad stuff happening in their immediate area, attend to the radio, run tags in the computer, answer calls, react instantly to a text, make sure the video camera is working and talk on the cell phone to their wife, girlfriend – or both.   (Ahem)

I also realize that humans are truly able to multi-task.  We do it by stratifying all of the events coming our way.  We put familiar, comfortable, repeatable stuff at a very low priority.  The more new, more dangerous, more unfamiliar an activity demands focused attention.

Some stuff just falls into what I term, “ambient awareness.”  Ever ride with a brand-new driver?  Remember when you were one?   Your eyes were glued to the road. Not so much, anymore.  Why?  Because driving has become familiar and comfortable.  You can attend to it as a peripheral item which allows you to simultaneously focus on other stuff around you.

Texting seems to be a frequent diversion for drivers around here. (ahem)


You can take that fact to the bank.  The limit comes from your total ability to process information at one time.  It could be a lot from a single source, i.e. a very intense video game, a gun battle, etc. or it could be a little stimuli from many places, like driving and all the other stuff mentioned earlier.

Here’s what is likely to kick your ass: your capacity drops as you run out of energy.  The body concentrates dwindling energy supplies on vital organs, like the heart.   Hence, your brain does without.  Worse, your senses get slashed in the process, too.

The Myth of Multi-Tasking


Yup, you got it!  If you are really tired or hungry: there may be stuff happening right in front of you that you don’t hear and you don’t see.  Sorry, Charlie.  That’s the way we are designed.

While hunger can usually be fixed rapidly, lack of rest cannot.  Therefore, when those energy supplies get low, you need to lay low until they are restored.

Happily, you can also expand your capacity to handle stimulus through exercise.  Just like making your arms too big for your uniform shirt by exercising them hard at the gym, you can do the same to your brain.


 If you saw the movie Rain Man you watched the depiction of an individual with what is called Savant Syndrome.  In the movie, Dustin Hoffman’s character can recall the number of matches dropped on the floor in a single glance. We probably know someone who can perform incredible feats that we “normal” creatures would find impossible.

Scientists don’t know what the exact top-end capacity of the human brain is.  They have found that we use a small portion of the brain’s potential and that we can grow, develop and build its capabilities.  The brain can be trained to see and distinguish objects at lightening speed and improve accurate retention.

Clearly, this kind of speed improvement would be a tremendous benefit in meeting today’s demands for Multi-Tasking.

During World War II, the military was having a problem with American pilots shooting down our own aircraft because at high speed they could not distinguish the difference between friendly and enemy aircraft.  

 A psychologist developed a system to flash visual images of both enemy and friendly aircraft at fractions of a second.  As the pilots practiced watching the images, their brains began to adapt to seeing them at high speeds.  With practice, they were able to instantly distinguish enemy vs. friendly aircraft at hyper speeds.

Training for cops is available today: Rapid Threat Recognition™.  This skill-based program requires using a different part of the brain than we normally employ. That is what makes it so effective. You begin using the part of your brain that can recognize images many times faster than the cognitive part of the brain allows.

Multi-Tasking SUPERMAN


Here is an exercise you can try as you are on patrol.  Look very quickly at a license number of a car in front of you.  Quickly look away and try to recall the entire number. Now look back and see if you are correct.  With practice your brain will begin to adapt to see the tag as a whole number.

You are learning to quickly switch between tasks.  You are learning to recognize elements of your environment without logically evaluating them.  You are improving the speed at which you are processing stimuli in your environment.  Sounds terrific, eh?


Your ability to Multi-Task is greater than a computer.  The machine can only handle one thing at a time.  Your brain truly can Multi-Task.   But, you do have limits.  Too much high-intensity stuff will blow your mental circuit breakers.  Also, low energy supplies cut your “mental strength.”   Handling 315 lbs. on the mental bench press won’t cut it when you are tired.  Don’t try that maneuver or you’re likely to end up with the bar on your brain’s neck.

Bodily needs and raw emotions drain you, as well.

  • Do you desperately need a bathroom break?
  • Are you so hungry that your stomach growls louder than the radio?
  • Did you have a big fight with your wife just before the shift?
  • Are you so horny that getting laid is all you can think about?
  • Are you feeling stressed-out over money or something else?

This is the time to keep your head down.  You are not mentally ready to become the town hero, at the moment.

Recognize the symptoms.  Listen to your mind, body and soul.  If it is screaming “overload,” you truly need to pay attention to that message.  We have all been there – even if you won’t admit it to yourself.  We understand.

I’d rather see a brother take a short break than to be visiting him in the hospital or worse, the funeral home.  That’s a show-stopper, pal.

After all, it’s all about saving just ONE life.


The Rapid Recognition System™ has been developed by Observation On Demand (O2D), specifically for Law Enforcement.  It helps cops to multi-task more safely and recognize threats more quickly.  For further, contact John Demand at jdemandjr@aol.com or (847) 275-9590.


COPS-L is an On-Line Roll Call in your inbox each day

THE COPS LIST is a simple, single source for law enforcement news from the major news-feeds:  Calibre Press, Department of Justice/legal updates, Federal Informer on case law, Law Officer, National Law Enforcement Officers Memorial News, Officer Down Memorial Page (ODMP), Officer.com, PoliceOne and other relevant sources of LE news.

Officers across the nation get LE news and exchange information here.  Don from Boston PD, “I get important information days (or weeks) earlier than from roll call.”  Chris in Chicago, “I get information about the LE national community which we would otherwise not learn,” and Bob in Dallas said it’s a concise, single news source automatically delivered to my INBOX each day.”

Originally designed nearly twenty years ago for the LEO who worked part time.  It grew rapidly to include those who don’t have a daily group roll call.  Today, about 1,000 cops: career officers, part-time, active, reserve / auxiliary, retired, non-sworn and other LE support staff are welcome on COPS-L.  There is NO COST and a member can opt-out at any time.
