Lesson Course 3. Paying Attention

How attentive are you? One way to check is to run this little thought experiment: sit quietly in a chair, with a second-hand watch or clock nearby, close your eyes, and check to see how long you can go without thinking of anything. If you can go more than 5 seconds without any thought, that is far better than average.

What does this little test say about attention? Actually, you are not paying attention as such, you are paying attention to not paying attention. In other words, you just measured your limited capacity to resist distraction. Resisting distraction is the other side of the focus coin. If you can resist distraction, you can focus on any object of thought without being distracted. So what? Being able to focus is a skill that is crucially important to developing your ability to remember.

         There are ways to develop the ability to focus. Before I get into that, however, let me illustrate a related point. You perhaps have heard the instruction: “Do not think about pink elephants.” I tell you now, “Do not think about pink elephants.” Were you able to not think about pink elephants? Unlikely. Real elephants are not pink. A pink elephant is such a compelling image so that you are hard pressed to not see it in your mind’s eye.

Make Memory Targets Compelling

This makes a point about focus. If the target of focus is compelling, it is hard not to focus on it. Thus, whatever you need and want to focus on is easier to attend if you make it compelling. If a target of focus is compelling, it becomes encoded more strongly. You learned in Lesson 1 that encoding is the first crucial step in the memorization process cycle. One of the best ways for a compelling focus of attention is to make a target of attention a mental image, either a literal simulation of the actual target or a metaphorical representation of it. Generally, the most robust images are not literal but those that are ridiculously exaggerated (like pink elephants). This tactic is the basis used by “memory athletes” who compete in international contests to see who can memorize the most material in the shortest amount of time. I will say much more about specific mental imagery tactics in Lesson 9 where mnemonics are explained.

The other obvious way to make compelling memory targets is to motivate yourself to remember. As I explained in my book on The Learning Skills Cycle, the centerpiece hub of the cycle is motivation to learn. Approach learning tasks with a zeal that drives you to do all things needed to memorize and the success in learning then strengthens the motivation to learn more. As I explained in the story about my “conversion” in the 7^th grade, once I learned how to get to the top of the class and how good that felt, I was motivated to achieve that standing every year.

Avoiding Distraction

While it is true that the brain processes information in parallel, conscious memorization operates serially. That is, you consciously attend one thing at a time, switching at high speeds from one targets of attention to another. Any time you switch targets, you disrupt the processes of encoding and initiation of consolidation. This explains why multi-tasking greatly impairs memorization.

School environments are notorious for creating distractions. Students in a classroom have to make special effort to stay focused on instructional material.

Learning to Focus

Conscious focus of attention is a skill that can be learned through deliberate practice. The best proof comes from Hindu ascetics who do such astonishing things as voluntarily regulating their heart rate and blood pressure or lying on a bed of nails. The Buddhist meditation practices provide a practical way for anybody to train their brains to focus—you don’t have to be a Buddhist. The technique that works for me is called “mindfulness meditation.” The objective is to be mindful of what you are thinking and to force yourself to think of only one thing, usually slow, deep breathing. All extraneous silent mental chatter and images are pushed out of consciousness.

See how long you can sustain sole focus on your breathing and keep out all intruding thoughts. Notice all things associated with the breathing, but nothing else. At first you may feel aches and pains you have not been attending because you were thinking of other things. Ignoring these aches consciously during meditation adds to the value of the exercise. Hear the sound of the moving air with each breath. Feel the pulse in your neck. If you don’t feel it, crook your neck or lie down to feel it in your back or hear it by turning your ear to a pillow. Notice the rhythm and the gradual slowing of breathing. Feel your clothes shifting position and the tension flowing out of your muscles, first in the jaw, then back and legs. The first time you try it, you likely will lose focus within a couple of seconds. But after a few days of 15-minute sessions, you will realize your brain has learned how to focus for several minutes or more. Not only does this kind of meditation teach your brain how to concentrate, it also lowers blood pressure, reduces memory-impairing stress, and contributes to peace of mind.

As you develop the capacity to focus, reinforce the training by being more attentive to every target of attention that you are trying to memorize. Also, notice what is associated with the information you are trying to memorize. If you are learning about an historical event, like the First Continental Congress, notice what is going on in the meeting hall, where it took place, why that place was chosen, what prompted the meeting, who stood out in the meeting, and so on. In short, notice the context in which things exist. Paying attention to such details at the time of initial encoding provides huge numbers of cues that strengthen the encoding and can serve as handles to help you retrieve the information in the future. The context obviously aids in understanding as well. Sometimes, just the understanding helps you figure out something you actually failed to remember.

Summary:

•   1 To strengthen encoding and the initial stages of memory consolidation, make memory targets compelling. The best way is to represent the targets as mental images.
•      Do not multi-task. Alter you learning environment as best you can to reduce distracting stimuli and thoughts.
•      Train your brain to focus. Make time for a 15-minute mindfulness meditation session every day and try to focus on your every experience throughout the day.
•      Don’t go around in a mental fog. Notice things. Be consciously aware of everything.

Next Lesson: Week 4. Think and Get Smart

The Perils of Multi-tasking

We live in the age of multitasking. Though a phenomenon of the young, older folks are being dragged into the age by the digital revolution in mobile electronic devices. Youngsters, as digital natives, are wired to multi-task, but they don't realize how multitasking impairs their impaired thinking skills. We call our phones "smart," but they can actually make us dumb. This may be one of the reasons that under performance in schools is so common.

Older folks tend to be amazed and awed by the multitasking ability of the young. But those in all generations should realize that multitasking does not make you smarter or more productive.

In school, multitasking interferes with learning. In the workplace, multitasking interferes with productivity and promotes stress and fatigue. Multitasking creates an illusion of parallel activity, but actually it requires mental switching from one task to another. This drains the glucose fuel needed by the brain, making the brain less efficient and creating the feeling of being tired.

Neuroscientist, Dan Levitan, reminds us that multitasking is stressful, as indicated by increased secretion of cortisol and adrenalin. He cites work showing that IQ can temporarily drop 10 points during multitasking. A brain-scan study showed that new information gets processed in the wrong parts of the brain and not in the hippocampus where it should go in order to be remembered. The most insidious aspect of multitasking is that it programs the brain to operate in this mode, creating a debilitating thinking habit that is permanent.

Constant switching creates a distractible state of never being fully present. It trains the brain to have a short attention span and shrinks working memory capacity. This is especially pernicious in young people, who are most likely to multi-task and whose brains are the most susceptible to programming of bad habits.

Multitasking not only becomes a habit, it is addictive. I see many youngsters who seem to have withdrawal symptoms if they can't check their phone messages every few minutes. Mail messages send an associated signal that someone thinks you are important enough to contact. This provides powerfully reward personal affirmation. Worse yet, like slot-machine payoffs, the reinforcement occurs randomly, which is the most effective way to condition behavior. It turns us into trained seals.

Why does anybody engage in behaviors that can turn them into a trained seal? One study indicates that susceptibility to task switching depends on the existing mental state. The researchers monitored 32 information workers, of near-equal gender, in the work environment for five days. Workers were more likely to switch off task to Facebook or face-to-face conversations when they were doing rote tasks, which were presumably boring. When they were focused, they were more likely to switch to e-mail. Time wasting in Facebook and e-mail increased in proportion to the amount of task switching. Over-all, the workers witched to Facebook an average of 21 times per day and to e-mail 74 times. Though the total time spent off-task was small (about 10 minutes on Facebook and 35 min on e-mail, the excessive task switching must surely have degraded the productivity of the primary work tasks. Why does anybody need to check Facebook 21 times a day or e-mail 74 times a day? This is compulsive behavior that has affected the entire workforce like an infectious disease.

How does on break the multitasking habit? The most obvious way is to reduce the opportunity. Turn off the cell phone. You do not have to be accessible to everyone at every instant. Don't launch the mail app, and when it is on, turn off the feature that notifies you about the arrival of each new message. If you don't need to use a computer or the Internet for the task you are working on, don't turn on your electronic devices. If a computer is needed, don't launch the browser until you actually need it.

Be more aware of your current mental state, because it affects your distractibility. If doing boring work, find ways to make it less boring and thus less tempting to switch tasks. If you are doing work that is engaging, make it a goal to stay focused for longer and longer times on such work. Set goals for increasing the time spent on task. You should at least be able to sustain focus for 30 minutes. Just as multitasking can condition bad habits, mental discipline can condition good attentiveness and thinking habits.

More Bad News for Multi-tasking

Memory formation is often prevented when one event follows too soon after an initial learning event. It is also true that memory of initial learning events can be blocked if you try to learn two things at once. In fact, learning may be disrupted for both things.

In a recent test of this phenomenon, a group of 29 people (17 to 30 years of age) was trained to discriminate two sound pips that differed in length by a fraction of a second. In one group of subjects, the training occurred consecutively, which ordinarily produces some inefficiency with learning because the second task interferes with remembering the first. In this study, some learning did occur, in spite of the sequential tasks. However, results from another group of subjects revealed that when practice on the two tasks was interleaved, there was no learning on either condition.

This indicates that acquistion (initial learning) is vulnerable to multi-tasking, perhaps even more so than when learning of one task is followed too soon by another learning task. In other words, multi-tasking can interfere with initial learning, just as it does with formation of memory.

Multi-tasking May Damage the Brain

We older adults tend to be awed at how young people today can multi-task. They seem to text message on cells phones, watch TV, listen to music, play a video or computer game, carrying on a conversation, and maybe even study their school lessons all simultaneously with apparent ease. Many adults, and even teachers, encourage multi-tasking because they think it is good stimulus for the brain and that learning how to multi-task is a useful skill. But I have already identified many research reports that show multi-tasking to impair formation of memory. Multi-tasking prevents the focused attention and reduction of distractions that are necessary for good memory.

Now there is a research report suggesting that the brain itself may be damaged by multi-tasking. Investigators at Stanford University gave questionnaires to their subjects to identify how much multi-tasking each person did. Nineteen subjects were "heavy multi-taskers" and 22 were "light multi-taskers." Comparison of how these two groups in thinking control tasks revealed that heavy media multi-taskers were more susceptible to interference from irrelevant environmental stimuli and from irrelevant representations in memory.In other words, they were more distractible. Then researchers tested the subjects for ability to filter relevant information from the environment and from their memories and to switch thinking tasks. A typical filtering test, for example, required subjects to detect changes in red triangles on a screen while ignoring blue triangles in the same pictures.

The heavy multi-taskers performed worse, even though their experience and presumed skill at multi-tasking should have made them more effective at these tasks. The heavy multi-taskers believed that they were good at multi-tasking, when in fact they were bad at every task that required multi-tasking.

It is not clear how much physical deterioration has occurred in brain from chronic multi-tasking. But at a minimum, multi-tasking is likely to reduce the brain's ability to develop concentration and thinking skills. Why do I suggest diminished thinking skills? Thinking is done with an orderly progression of items in working memory. Multi-tasking bombards working memory with scrambled and unfocused information and probably keeps the brain from learning how to optimize focus and orderly sequencing of thoughts through what I call the brain's "thought engine."
