M.I.T. Explains Why Bad Habits Are Hard to Break 231

Ant writes "CNET News.com says habitual activity (e.g., smoking, eating fatty foods, gambling, etc.) changes neural activity patterns in a specific region of the brain when habits are formed. These neural patterns created by habit can be changed or altered. But when a stimulus from the old days returns, the dormant pattern can reassert itself, according to a new study from the M.I.T., putting an individual in a neural state akin to being on autopilot... The neural patterns get established in the basal ganglia, a brain region critical to habits, addiction and procedural learning."

    Disclaimer: posting on slashdot is a hard habit to break... I can't stop.

    Interesting article, but a little thin on details. But if true in some ways I sigh in relief cuz it helps explain:

    • why I always jump to make an early slashdot post
    • why I always used bulleted lists in my posts (check it out!)
    • why "You" always mod me troll or flamebait
    • dupes
    • why I edit everything with vi(m)
    • why crime show dramas beget crime show dramas (just how many nights a week are CSI and Law and Order on these days?)
    • why the Yankees are a perennial playoff team
    • why the Cubs never make the World Series
    • why Larry King marries wife #X
    • why Donald Trump fires Apprentice #X
    • why Steve Ballmer throws chairs across the room
    • why Bob Dylan mumbles instead of sings (kidding)
    • why people wait at all costs and discomfort to get home and take a dump

    Another mystery solved perhaps.

    My followup question is, is it possible to break these patterns, ever? Or are we destined for eternity to be creatures of our own habits? Should we stop buying self-help books?

    • why I always jump to make an early slashdot post - You fail it.

      On a behavioral level, this finding is nothing new. Hermann Ebbinghaus [yorku.ca] introduced the idea of savings in relearning [google.com] in the 19th century. This finding has been replicated countless different ways, including being replicated in neural network simulations.

      Nor is it news that this involves neurons. Hint to cnet: all of mental life involves neurons.

      What's scientifically interesting is which neurons are involved. The researchers are trying to map out the circuits involved in order to better understand the underlying process. That is at least potentially interesting.

      My followup question is, is it possible to break these patterns, ever? Or are we destined for eternity to be creatures of our own habits? Should we stop buying self-help books?

      One way to break an association is to develop a competing association. If Stimulus A triggers Response B, then you develop a new association between Stimulus A with Response C. That makes it harder to fall victim to the savings-in-relearning effect when you're faced with Stimulus A in the future, because you won't just be left hanging to try to suppress your impulse to respond with B.

      And yes, you should stop buying self-help books.

    Hell, any former smoker could tell you this much. I smoked for less than a decade, and I quit over 5 years ago, no relapses. However, sometimes an almost reflex gets triggered by the smell of tobacco, or just seeing a cigarrette, and it's like my arm itches to go through the motions, what I've seen described as a "ritual" of sorts, of lighting a smoke. This all occurs in my mind a split second before the conscious mind kicks in and realizes what is occurring, and takes control again.

    Trust me, this is a very accurate description of how some of these habits ingrain themselves into your mind.

    • Aye, I'm an ex-smoker, too, and your words ring true.

      From TFA:

      The neural patterns get established in the basal ganglia, a brain region critical to habits, addiction and procedural learning.

      Not sure if it's what you're looking for, but since addiction and procedural learning reside in the same area of the brain, dealing with cravings by performing a different procedure ( i.e. doing something else until the craving passes ) might help.

Concentration itslef can be a hypnotic function, and when people worry and struggle with a problem they are actually deepening the psychic hold it has.

    This came out of alzheimer's research about 15 years ago.

    Your brain optimizes to think what it thinks about a lot. (Why Slashdot readers don't morph into female genitalia or came controllers shows that human thought can't change matter.)

    When you try to "break" an old habit, it's easy at first. After a few days, the brain realizes the optimizations are starting to disappear and it works to reinforce those structures.

    The good side of this is that you don't have to re-learn how to use the toilet, eat, talk, etc. The bad side is you can't choose which thoughts are reinforced other than brute force to get past the recovery period. Even so, it's easy to go back to old optimizations. Think of it as being similar to a fold in a piece of paper. The fold can't ever be removed, just made less prominent. The paper will still have the tendency to fold at that position.

      The parent makes a very inaccurate assumption of why habits are hard to break.

      The brain does not independently attempt to reinforce any particular pattern of its own accord - not even the subconsciousness performs this level of autonomous subversive activity.

      However - the limbik region responsible for manifesting motivation and associating that motivation with behavior makes it feel that way. Which is to say, if someone smokes to relieve stress, and then stops smoking, that stress no longer has the familiar outlet. As the stress then continues to build, the limbik system increases the negative pressure associated with the typical relief and the urge to resume the habit also increases. However, if the stress (or whatever outlet or positive association [such as socialization or pleasurable sensation]) resumes a separate outlet, the motivation is satiated and the originally satisfying habit is more easily overridden.

      The brain does not have an effective back-end cron process for optimization - it does well what it does *frequently*, and is a very very reactive organ.

    Here is a link to the primary article. [nature.com]
     
    And here is the abstract:
    Learning to perform a behavioural procedure as a well-ingrained habit requires extensive repetition of the behavioural sequence, and learning not to perform such behaviours is notoriously difficult. Yet regaining a habit can occur quickly, with even one or a few exposures to cues previously triggering the behaviour. To identify neural mechanisms that might underlie such learning dynamics, we made long-term recordings from multiple neurons in the sensorimotor striatum, a basal ganglia structure implicated in habit formation in rats successively trained on a reward-based procedural task, given extinction training and then given reacquisition training. The spike activity of striatal output neurons, nodal points in cortico-basal ganglia circuits, changed markedly across multiple dimensions during each of these phases of learning. First, new patterns of task-related ensemble firing successively formed, reversed and then re-emerged. Second, task-irrelevant firing was suppressed, then rebounded, and then was suppressed again. These changing spike activity patterns were highly correlated with changes in behavioural performance. We propose that these changes in task representation in cortico-basal ganglia circuits represent neural equivalents of the explore-exploit behaviour characteristic of habit learning.

    Fascinating findings. I find that gathering information is a bad habit of mine. My dad once described himself as an encyclopedia of useless information. As they say, the apple doesn't fall far from the tree. He drives a crosscountry rig now (no longer a computer field service technician repairing motherboards as he did in the early 80's and earning far more money) so he's avoided the terrible lure of the internet (except on weekends). I find myself abusing RSS technology to feed this habit of mine. I can't believe how much more info I cram into my brain because of RSS...

    Of course, for many these scientific findings produce a "duh" response. Often science is filled with elaborate studies that simply prove what we already commonly believed or "knew". But no harm done. I think it's exciting to understand the process more fully. I wrote a blog about another study that was done on addictive behavior (ADD: Addicted to Information [blogspot.com]) - specifically drugs - last March. That research worked on showing how this effect of losing willpower to addictive behavior occurs physically/neurologically in the brain. Fascinating stuff. I related it to my addiction for information - an insight of my wife's, btw. I'm not nearly as insightful or clever.

    What I'd like to see, however, is more work being done on how to unlearn habits. How to retrain the mind to not need whatever fix ails it. For instance, I'd like to reclaim an hour of my day without feeling compelled to read more and more news as is the problem this week, or watching too much TV as was the problem last month. My ADDled mind shakes off one habit only to pick up another. I try to build barriers, but as an earlier poster pointed out by example of Brian Eno, we simply bypass the artificial detours we construct. It would be better to retrain ourselves and eliminate those neural pathways that fire up upon familiar stimulus.
