Learning To Be Stressed

People are constantly exposed to stressful situations. These may be physical (like participating in marathons, being exposed to radiation, and, perhaps surprisingly, exposed to sedatives or anesthetics). But stress can also be mental, wherein we become anxious and worried over certain events, existing or anticipated. Whether physical or mental, stress activates a brain network involving most directly the hypothalamus, the pituitary gland, and the adrenal cortex to release stress hormones. Such hormones include several cortisone-like compounds called glucocorticoids, and the most prominent one in humans is cortisol.

Glucocorticoids have profound effects on both body and brain. Regulation of glucocorticoids is accomplished by the brain, and learning experiences have profound effects on this control system. Most of what was initially known about glucocorticoids was their effect on the body. I had the great thrill of visiting the pioneer in this field, Hans Selye, in his laboratory complex at the University of Montreal. He had a whole room full of medals, awards, and honorary doctorate diplomas. He won practically every research accolade there was, except the Nobel Prize, one of several grievous slights by the Nobel committee. Dr. Selye wrote an autobiography for my book, Discovery Processes in Modern Biology.

Effects on the Body

Selye’s research led him to formulate the widely accepted concept of the glucocorticoid system as accounting for a “General Adaptation Syndrome,” which basically explained how the brain and body respond to stress. He discovered that glucocorticoids are “Goldilocks” compounds. That is, a little doesn’t do much, a lot is damaging, and intermediate levels are “just right.”

A moderate amount of cortisol is what is normally released every morning before you awaken. By the way, this is the reason surgeons want to operate early in the morning. This release helps prepare the body for the day’s activities by mobilizing blood glucose, typically by breaking down fat and, if needed, protein stores. Glucose is especially important for the brain, which has huge demands for energy, and which can only burn glucose for energy. Neurons are energized and memory ability is enhanced. Another useful thing cortisol does is to reduce the release of cellular chemicals that cause inflammation.

However, the hormone also inhibits systems that channel resources for growth and reproduction, impairs bone formation, and inhibits the immune system. Basically, the idea is that glucocorticoids help brain and body to respond to temporary emergencies by assigning lower priority to other physiological needs.

The rub comes when stress is prolonged. Selye discovered that the beneficial adaptation to temporary stress cannot be sustained in chronic stress. The system becomes exhausted and control breaks down.[1] Under chronic stress, body muscle mass decreases because the system has been breaking down proteins in order to generate energy. Inflammation bathes cells in toxic chemicals. Infections increase because the immune system has been compromised. In obese people, glucocorticoid levels cumulatively increase in fat cells, increase fat deposits still further, and increase the likelihood of type 2 diabetes and cardiovascular disease.[2]

Effects on the Brain

In the case of brain, persistent high levels of glucocorticoid often causes depression. Memory ability is impaired. Brain degeneration and cognitive decline accelerate. Many neurons are actually killed. What I want to stress here is that chronic high levels of cortisone change the neural circuitry that regulates its release. In other words, the brain learns a new way of functioning if constantly bathed in high levels of cortisone.

Effects of Learning

Few people make the connection between glucocorticoid control and learning. The neuronal circuits that control hormone secretion learn from stressful experience, just as all neurons learn from whatever they experience. What neurons in the cortisol control circuit learn in chronic stress is that the usual controls can’t work any more.

A typical response to a repeated stress of a certain type (for example, constant quarrels with a spouse or repeated job failures) can be habituation. It’s like “tuning out.” Repeated exposure to the same stress teaches the neurons to stop responding as much as usual. Thus, there is less of the benefits that glucocorticoids provide.

At the same time, the hormone control system becomes hypersensitive to other stresses, especially unpredictable or especially severe stresses. The control system learns to over-react to everything other than the stress to which it has habituated. Now, the damaging effect of too much glucocorticoid becomes pervasive, both for body and brain.

Whether the brain learns stress-coping strategies depends on conscious over-ride of hyper-active responses to stress, because the neural system (the limbic system) that operates our emotions also regulates the glucocorticoid control system. We can not only reduce excessive glucocorticoid but also teach our brain better ways to deal with stress by doing the following:

·         Simplify and organize our life,

·         Do one thing at a time and finish it,

·         Find pleasure in the little things,

·         Learn to have a more positive attitude,

·         Laugh and be happy,

·         Suppress anxiety,

·         Be more rational and less emotional,

·         Develop supportive social relations,

·         Reduce exposure to stressors.

Does Humor Make You Live Longer?

I just attended a “Laughter is Good Medicine” seminar put on by a local hospital. The speaker pointed to evidence showing that laughing has such good effects as:

·         Reduce blood pressure

·         Lower blood glucose

·         Dull pain

·         Alleviate stress and anxiety

·         Improve feeling of well being

and it even burns substantial calories.

I suspect humor also improves longevity, though I only have anecdotal and presumptive evidence for that. But the evidence seems hard to dismiss. Think about how long so many classic stand-up comedians of the

preceding generation lived.

Most of these comedians were actively performing right up to their last days. Here is a listing of comedians most people in my generation will recognize and their age when they finally died.

Bob Hope, 100

George Burns, 100

Phyllis Diller, 95

Milton Berle, 94

Henny Youngman, 92

Victor Borge, 91

Dick Van Dyke, 88 (still alive)

Jimmy Durante, 87

Jerry Lewis, 87 (still performing)

Bea Arthur, 87

Groucho Marx, 87

Jonathan Winters, 86

Jack Paar, 86

Red Skelton, 84

Bob Newhart, 84 (still performing)

Soupy Sales, 83

Rodney Dangerfield, 83

Mel Blanc, 81

Johnny Carson, 80

Jack Benny, 80

These comedians obviously had good memories, because even in their old age they could spout a steady stream of jokes from memory without a teleprompter. To have a good memory, you have to have a healthy brain, and a healthy brain often is healthy because the body is healthy. Healthy bodies live longer.

Let’s also remember that some of these people led a hard life, mostly on the road, in an era when people in general did not live that long.

One thing is for sure. Whether or not humor makes you live longer, it surely does make you live happier.

Older People Make Better Decisions

In an earlier post, I reviewed research showing that seniors compensate for any loss of memory ability by having developed learning and memory schemas over the years. Such schemas are ingrained strategies and ways of efficient learning that improve with experience and age.

Now I have come across recent research that shows another age-developed skill: improved decision-making ability. Teenagers are notorious for poor decision-making. Of course that is inevitable, given that their brains are still developing and they have had relatively little life experience to show them what works and what doesn’t. Unfortunately, what doesn’t work often has more emotional appeal, and most of us at any age are more susceptible to our emotions than to cold, hard logic.

Seniors also are prone to poor decision-making if senility has set it. Unscrupulous people take advantage of such seniors because a brain that is deteriorating has a hard time making wise decisions.

In between teenage and senility is when the brain is at its peak for good decision making, especially improving as one gets older. Some Eastern cultures venerate their older people as generally being especially wise. After all, it you live long enough, and are still mentally healthy, you ought to make good decisions because you have a lifetime of experience to teach you what future choices are likely to work and which are not.

Much of that knowledge comes from learning from one’s mistakes. On the other hand, some people, especially the young, can’t seem to learn from their mistakes. In any case, the best strategy of all is to learn from somebody else’s mistakes so you don’t have to make them yourself.

Learning from your mistakes can be negative if you fret about it. Learning what you can to avoiding repeating a mistake is one thing, but dwelling on it erodes one’s confidence and sense of self worth. I can never forget the good advice I read recently from, of all people, T. Boone Pickens, who has lost and regained fortunes several times. He was quoted in an interview as saying that he was able to re-make his fortune on multiple occasions because he didn’t dwell on the failures. He credited that attitude to his Oklahoma State basketball coach, who told the team after each defeat, “Learn from your mistakes, but don’t dwell on them. Learn from what you did right and do more of that.”

A key reason seniors make better decisions is that they have a richer store of knowledge and experience. Any choice among alternative options is affected by how much information for each option the brain has to work on. When the brain is consciously trying to make a decision, this often means how much information the brain can hold in working memory. Working memory is notoriously low-capacity, so the key becomes remembering the sub-sets of information that are the most relevant to each option. People are more likely to remember items they value and to forget low-value items.[1]

It turns out, apparently, that older people are more likely to remember the most useful information and thus make better conclusions and decisions. The National Institute of Aging began funding decision-making research in 2010 at Stanford University’s Center on Longevity. Results of their research are showing how older people often make better decisions than younger people.[2]^,[3]

As one example, older people are more likely to make rational cost-benefit analyses. Older people are more likely to recognize when they have made a bad investment and walk away rather than throwing more good money after bad.

A key factor seems to be that older people are more selective about what they remember. For example, one study from the Stanford Center compared the ability of young and old people to remember a list of words. Not surprisingly, younger people remembered more words, but when words were assigned a number value, with some words being more valuable than others, older people were better at remembering high-value words and ignoring low-value words. It may be that older people selectively remember what is important, which could explain why they make better decisions.

Working Memory Executive Control

Do you consciously monitor your working memory? That’s the limited-capacity memory you use when looking up a phone number, for example. If you fail to keep the numbers actively in mind while dialing, you may have to look up the number again. In other words, do you check yourself to see if you are still paying attention to what is in your working memory? Is your mind wandering away from what you are trying to hold in working memory? The cure is to deploy your brain’s innate capacity for executive control over working memory.

For more complicated memory chores than dialing a phone number, are you consciously aware of updating what is in your working memory at a given moment with new information? Do you think about being able to recall information you have just received—as when you are reading? Or do you ever willfully suppress what is in your working memory—as for example, expunging an unpleasant thought.

These questions deal with how well you are consciously aware of the likelihood you can recall what you are experiencing. I suspect that most of us exert some conscious executive control over working memory, but not nearly as efficiently as we could or should. Does it matter? Well yes, because controlling what is in your working memory affects the ongoing thought processes that are using the information that is in working memory. Moreover, how well you monitor your working memory affects how well the information registers in your brain and how well it can become consolidated into a more lasting memory.

I explain the consolidation process and ways to enhance it in my book, Memory Power 101.

Executive control of memory is relatively new in memory research, but one group reports studies suggesting that such research will prove fruitful. A year or so ago, this group’s poster presentation at the Society of Neuroscience meeting intrigued me, and I am delighted that the work has now been formally published.

One of their experiments evaluated listeners’ ability to monitor their moment-to-moment working memory storage capacity as new information arrived. As they listened to recorded word lists, experimenters told the subjects to pause the input at the maximum point that would still allow them for perfect real-time memory recall. That is, they pressed a key to pause the input of words in the list at the latest point at which they believe they would have perfect recall. Interestingly, all subjects paused the recording consistent with their known working memory span, as had been determined in pre-experiment testing. In a follow-up experiment, experimenters reduced the sound volume of the word list so that more effort had to be exerted to perform the task. Under these conditions, subjects were much less accurate in matching their listening to their natural working memory capacity and thus their learning was not optimal.

Obviously, such results suggest that making tasks more difficult can degrade thinking and learning. Teachers and professors who speak softly or with foreign accents should take note. Whatever benefit accrues from the challenge to pay better attention under difficult situations is offset by limitations in working memory storage capacity. Examples of degrading influences in addition to sound volume in listening to information include:

Listening is made more difficult by:

·         Extraneous noise

·         Unfamiliar speech accents

·         Speaking too rapidly

·         Speaking too softly

·         Simultaneous presence of visual stimuli that conflict or distract

·         Irritating or distracting mannerisms of the speaker

Reading is made more difficult by:

·         Font and page design selection

·         Convoluted syntax, awkward sentence structure

·         Unfamiliar vocabulary

·         Distracting visuals

·         Wordiness, poor grammar

·         Poor reading technique (tracking with finger movements, random eye fixations, small fixation span (a few letters or one word at a time)

In all situations, an important factor is whether the listener or reader has control over the speed of information presentation. Thinking and learning are compromised if a person has no control over chunking of information input and matching the input to their working memory storage capacity.

Another factor, not considered in this study, is the likelihood that people differ significantly in conscious executive control capability. We know, for example, that some people can hold focus much better than others can, and this certainly affects their ability to optimize working memory storage of information input.

Can working memory executive control be trained? There are already effective training protocols for expanding working memory capacity (as in the number of items you can hold in working memory). I suspect that we will soon see training programs to enhance executive control of working memory.

To summarize, you can optimize thinking and learning by willfully controlling the ease and convenience of information input as well as by how well you have developed a habit of conscious executive control.

Memorization Is Not a Dirty Word

School is ending for the year, and students surely welcome the break. But they will do well to think on how they learn to learn so that next Fall they can be more successful with less effort. Interesting how that reminds me of my e-book for students, Better Grades, Less Effort.

In my experience with students, both the college students I teach and the secondary students that teachers tell me about, the biggest weakness students have is that they either try to remember school material by rote memorization or have no strategy at all, relying on some kind of magical mental osmosis.

 Even among students who rely on rote memory, they generally lack much of a strategy for memorizing, relying on varying degrees of casual “looking over” the instructional material until they think they can remember it. Experiments show that students routinely over-estimate how much they remember and under-estimate the value of further study. Moreover, many educators at all levels have disdain for memorization, stating that we should focus education on teaching students to think and solve problems, as if you can think and solve problems without knowing anything. Too many teachers regard memorizing as old-fashioned and even destructive of enlightenment.

Disdain for memorization is a relatively new phenomenon in education. In ancient times, people took great pains and pride in memorizing huge quantities of information. The advent of printing greatly reduced the need to memorize history and cultural mores. In modern times, we have the Internet, where you can just Google what you need to know. So who needs to get brain-strain trying to remember things?

Now we have a book by Samuel Arbesman, The Half-Life of Facts: Why Everything We Know Has an Expiration Date, where he argues that there are no lasting facts. They all have a half life, that is, the number of years it takes to falsify half of what you think are facts. He argues that new “facts” are made all the time, often replacing what we had previously thought were facts. He argues we should just stop memorizing and look up whatever current facts we need on the Internet. But if there are no lasting facts, how are those you find on Google any more valid than those you memorize and can deploy in real time.

There are some serious errors in Arbesman’s position.

1.      Many facts are immutable; that is, they don’t have a half-life. Events in history did actually occur, and while revisionist writers of school history textbooks may change the reporting of those events, the facts remain true. Nixon covered up Watergate, Obama obfuscated Benghazi. The fact of DNA as a basis for heredity is not likely to change.

2.      Many facts that do change will not change in a given person’s lifetime and thus will be useful in daily living.

3.      The Internet is flooded with error, propaganda, and un-vetted assertions.

4.      You don’t always have Internet access.

5.      In many situations, it is not practical to look up what you need. Ever try to read or speak a foreign language where you have to look up most of the words? Ever try to use computer software where you have to repeatedly refer to the instruction manual?

6.      Expertise in any field of endeavor requires a great deal of memorized “facts.” And if you want to succeed in life, it pays to be an expert.

I can easily make a strong case for memorization, especially for schools. Here is a list supporting the importance of memorizing:

1.      Memorized information is always with you, even when you lack the time or access to sources where you could look it up.

2.      We think and solve problems with what is in working memory, which in turn is memory of currently available information or recall of previously memorized  information. The process of thinking is like streaming video on the Internet: information flows in as short frames onto the virtual scratch pad of working memory, successively replaced by new chunks of information from real-time or recalled memory. Numerous studies show that the amount of information you can hold in working memory is tightly correlated with IQ and problem-solving ability.

We think by shuttling small batches of information as we experience it or from memory onto a  virtual  scratchpad called working memory. These batches are shuttled  sequentially into our  processing networks ("thought engine"). How well we think depends on what is on the scratch pad. From Klemm, 2011. Atoms of Mind, Springer.

3.      Memorization provides exercise for the mind. This is the reason schools used to require students to memorize poems, Bible verses, famous speeches, etc. The true advantage of such exercise is that generates mental industriousness. Any teacher will tell you that many students today are mentally lazy. Memorization also trains the mind to pay attention and focus intensely. Such skill also seems to be lacking in many youngsters, which is most obvious in the growing number of kids diagnosed with ADHD.

4.      Memorization trains the brain to develop learning and memory schemas that facilitate future learning. Learning schemas develop as you acquire competence in an area—call it skill A. Now, when you need to learn a new and related skill, B, you mind says to itself, “I don’t know how to do B. But I do know how to do A, and some of that can be applied to learning B.” Memory schemas are memorized frames of reference and association, where having memorized fact A, you have an association handle for memorizing fact B.

5.      If you learn strategies for memorization, as opposed to the rote memory approach of looking information over repeatedly, you accelerate the ease, speed, and reliability of learning new things.

Bottom line: the more you know, the more you can know!

Regardless of where you stand on the importance of memory, most people believe that learning is a good thing. But what good is learning if you don’t remember it?

If you are convinced that you or your loved ones could benefit from better memory, many ways to do it are explained in my books, Better Grades, Less Effort (e-book for students) and Memory Power 101 (paperback from SkyhorsePublishing.com). 

New Discoveries on Optimizing Memory Formation

As each of us goes through life, we remember a little and forget a lot. The stockpile of what we remember contributes greatly to define us and our place in the world. Thus, it is important to remember and optimize the processes that make that possible.

People who compete in memory contests (“memory athletes”) have long known the value of associational cues (see my Memory Power 101 book). Neuroscientists have known for a long time about memory consolidation (converting short-term memory to long-term form) and the value of associational cues. But now, important new understanding is arising from a research lab at Northwestern that links cueing to “re-consolidation” and reveals new possibilities for optimizing long-term memory formation.

The underlying research approach is based on such well-established memory principles as:

1. When information is first acquired, it is tagged for its potential importance or value.
2. Such tagging is influenced by multiple factors such as repetition, attention, emotion, or purpose.
3. Valuable memories get preferentially rehearsed, either through conscious will or by covert (implicit) brain processes.
4. Rehearsal episodes reactive the memory and enhance long-term remembering because each re-consolidation episode builds on prior ones and strengthens the neural circuits that store the memory.
5. Effectiveness of recall during rehearsal is promoted by use of relevant cues, that is, information that was associated with the original learning material.
6. Such cues are effective, even when delivered during sleep.

The pioneering study involving sleep learning appears to have been done by John Rudoy and colleagues in 2009 [1}. They showed that people recalled locations of memorized objects better if they heard sounds associated with the locations during their sleep that had been earlier associated with the learning of object locations. The basic finding was replicated in a follow-up study [2].

Most recently, a study by another group also confirmed and extended this concept of using cues during sleep to promote memory formation.The study involved 60 people in their early 20s, screened for good memory ability.[3] All subjects participated in a four-hour learning period beginning in late morning. The learning consisted of 72 images placed in specific locations on a tile-like screen and presented one at a time. As each image appeared a corresponding sound was associated, intended to serve as a learning cue. For example, a dog picture would be associated with barking, cat with meow sound, etc. To create a value bias, each image had a superimposed number representing how important it was to remember this item and its location upon later testing. Subjects were given financial reward for how well they remembered, and thus remembering high-value images was a priority. Half of the images had high value assignments, while the rest had low values.

 Subjects were assigned to four groups:  

1. Groups 1 and 2 were tested to see how well they could remember where each object had appeared during the learning phase. They then took a 90 min nap while their EEGs were recorded. Half of these subjects heard white noise while the other have was presented the original sound cues of low-value images during non-REM sleep at a level that did not cause awakening. At the end of the nap, recall was again tested.
2. The procedure in two other groups was similar except that these subjects did not nap. One of these groups watched a movie during the 90 minutes after the learning session, while the other group listed to the low-value sound cues while performing a working memory task.

Not surprisingly, the studies revealed that high-value images were remembered better, irrespective of whether or not a nap was taken. The practical point is that we remember better the things we value and find to have positive reward value. This reminds me of the sage saying that T. Boone Pickens repeated from his basketball coach, who told players after each game: “Don’t dwell on your mistakes. Think about what you did right and do more of that!”

In the study, half of the low-value associations were rescued by cueing during wakefulness and all of them were rescued by cueing during sleep, even though only half of the images were cued. Notably, the best effects occurred during the deepest stage of sleep. No explanation was given to explain the sleep benefit, but I suspect it is because the sleeping brain is not distracting itself with irrelevant thoughts. This is consistent with the finding that low-value memories were not rescued well during REM sleep, when the brain is busily engaged in dreaming. The REM-sleep finding is at variance with other studies that reported a memory consolidating benefit of REM sleep. Apparently, the test conditions make a difference and more research is needed here.

Low-value associations were preferentially forgotten in the group that was not allowed to nap. This likely signifies that a brain busily engaged with other thoughts is less able to selectively consolidate memories, and only high-value items are likely to survive. This accords with the long-held theory that distractions and multi-tasking interfere with memory consolidation.

In summary, memory optimization would seem to require one to:

1.    Create associations that can serve as memory cues.

2.    Place a high value on the cues and their targets.

3.    Repeatedly present the cues and replay the initial information. When awake, present the cues in self-test mode. When asleep, even better results would obtain if cues were presented at a level that does not cause awakening during the early night sleep when sleep is deepest and there is little dreaming.

10 Ways to Make Memory Rehab Work

Physical exercise can rehabilitate bodies that have grown soft and flabby. Can mental exercise rehabilitate brains that have deteriorated because of disease or age? Maybe.

A published scholarly review has examined the research literature on this issue and arrived at several useful conclusions:

1.      Focus, Reduce Distractions. The two common causes of forgetting, in both normal people and those with impaired memory, are a) failure to register new information effectively, and b) interference from conflicting sensations and thoughts.

2.      Customize the Rehabilitation Needed. Rehab need to take into account the type of memory therapy and the cause and severity of the impaired memory capability.

3.      Learn in Small, Frequently Repeated Chunks. New information has to be re-packaged for memory-impaired people so that it is in simple, concrete form, in small chunks, and repeated frequently — with patients required to re-state the information and make explicit associations with what they already know. (Notice how this sounds like the way one needs to teach young children).

4.      Practice Attentiveness. Attentiveness to new information can be enhanced by self-cueing, wherein patients remind themselves to be more attentive at crucial moments. This can even be done by creating a conditioned reflex in which a cue signal conditions greater attentiveness. (Notice how this sounds like how you “clicker” train dogs).

5.      Uses Mnemonics. Mnemonic tips and tricks can help. This includes using acronyms, rhymes, stories, and constructing mental images.

6.      Find Ways to Compensate. Even in patients with severe impairments, some aspects of memory, such as subliminal or implicit memory, may have been spared and can be exploited to compensate for the lost ability.

7.      Spread Rehearsals Over Time. Memory rehearsal is more effective if it is spread out over time rather than bunched into a few closely spaced sessions.

8.      Manipulate the Cues. Be more aware of cues you are using. A “vanishing clues” approach can help. For example, in a rehearsal session, cued retrieval might begin with cueing the first three letters of a target word, then repeating later with two, then  one, and eventually no letter cues.

9.      Minimize Error, Lest you Learn the Errors. Trial-and-error learning is generally less effective than learning conditions that minimize error, because error responses can get stored as memories that compete with the right answers. In short, it is better to not know than to generate wrong answers.

10.  Use Memory Crutches. Using external memory aids (sticky notes, wall charts, notebooks, etc.) should help, bearing in mind, however, that using such aids may themselves be a memory task. It is like having a schedule calendar and forgetting to check the calendar. Smart phones and radio paging devices (“NeuroPage”) can be especially helpful because they remind the patient when to check on the stored information. In some patients, repeated use of such aids develops a habit for target tasks and these may even generalize to certain non-target tasks.

These ten approaches are some of the same approaches that work especially well in people with normal memory capabilities. To make them work in patients with impaired memory just takes more effort, patience, and time.

Getting Out of a Rut

Why is it so hard to change behavior, or attitudes, or personality? I’ll tell you why. These things are habits. Habits are well learned and they persist from mindlessness.

Our behavior, attitudes, and personality are predisposed by genetics but also ingrained by repeating and reinforcing them over long periods. Thus, the older you get the more inflexible you get. But I see teenagers stuck in ruts too, and they are less likely to have the fronto-parietal cortex executive control to impose changes on themselves.

Regardless of age, being in a rut comes from learning to the point of creating a habit. Habits are really hard to change. Wendy Wood, in her review of the recent book, The Power of Habit, points out that contextual cues trigger habitual behavior. In other words, when you are in a rut, you have mindlessly outsourced your brain’s executive control to these cues. You run on auto-pilot. It is easier to respond to such cues reflexively than think about it and do something else.

Cures for reforming habits require attention to the triggering cues as the core of self-control strategies. When an unwanted response is activated from memory, it needs to be inhibited. Bad habits, unlike responses to temptations, are controlled most effectively through spontaneous introspective awareness and executive control (“Why am I doing this?”…“I don’t want to be doing this”… “don’t do it”… “am I backsliding?”) Vigilant self-awareness and monitoring apparently do not change the strength of the habit memory but are effective because they enhance executive control processes. Wood suggests that the most promising way to break a habit is to “disrupting habit cues so that the old response is not brought to mind and new habits can be learned.”

Some examples of cue awareness and disruption include:

1.    If you over-eat, use smaller plates or put smaller helpings on the plate.

2.    If you can’t focus and your mind wanders, notice distractions for what they are. Practice meditation.

3.    If you are hyper-critical or argumentative, recognize the instant you disagree.

4.    If you are lazy, be aware of your environment when you aren’t doing anything.

5.    If you are boastful, notice the situation that makes you want to boast.

If you want to get out of a rut, another important aid is to substitute a new and more desirable habit. I learned this years ago when I tried to quit smoking. I succeeded many times—in other words, I failed to really quit. Only when I decided to take up jogging and forced myself to do it persistently, was I able to substitute the positive reinforcement of nicotine with the positive reinforcement of the endorphins that are released during jogging.

To substitute a better habit, you must pick something that is likewise reinforcing and repeat it enough for it to become a habit. It also helps to simultaneously remove the cues that trigger the old bad habit. For example, when I finally quit smoking, I made myself go jog when I had a strong urge to smoke. Even though I had an urge to smoke many times a day yet only jogged once daily, this single substitution act seemed sufficiently helpful.

Some examples of habit substitution include:

1.    If you eat more meat than you want, find tasty vegetarian menus.

2.    If you gossip, restrict all gossip to praise talk.

3.    If you procrastinate, create a habit of doing the hard things first.

4.    If you whine, make yourself provide positive interpretations.

5.    If you associate with people who are dragging you down, spend more time with new associates who can lift you up.

Finally, we have to stop making excuses. Our usual attempts to blame things on “bad genes,” are misleading. In recent years, scientists have discovered that most of our DNA does not have a coding function. They used to call it “junk” DNA, presumably just carried along as useless sludge in the stream of evolution. Now they discover that “junk DNA” actually controls the expression of the coding genes. New discoveries in the field of “epigenetics” are showing that what we think and do influence if and when many of our coding genes are expressed.
