A recipe for happiness or procrastination?

January 19, 2009 in Blogs, Psychology Today by Psychology Today

A  story today in the New Zealand Herald reports that the CALM (Computer Assisted Learning Method) Web site allows students to download audio files that provide information about long-lasting happiness – ways to harness mental resilience, healthy relationships and finding meaning in life. Do these downloads have a downside? Even this short news story indicates that they might. Based on positive psychology, Dr. Tony Fernando ( Department of Psychological Medicine, University of Auckland ) originally designed the Web site for medical students. As William Liando quoted Dr. Fernando in today’s New Zealand Herald, "A lot of them are incredibly smart and gifted young people, but what they often don’t know is there’s a very high level of stress [in their academic life]." Dr. Fernando wanted to help by providing resources for students to cope with this stress. The content of the Web site is certainly based on what recent research tells us about happiness (e.g., it’s not what we own that makes us happy), and it’s not my purpose today to comment on the Web site per se. What caught my attention in this brief news report was a concluding quote of a student user. Liando writes, "Third-year medical student Phillip Chao is a convert and told the Herald the site helped him most before and during exam time. ‘Instead of listening to music or doing other things when I feel like I’ve had enough of studying, I can go to the CALM website and listen to a few meditation sessions.’ However, the 19-year-old, who downloads the audio files to his iPod for convenience, warned it could also be a tool of procrastination. He said he occasionally used his time on the website to stay away from his books " (emphasis added). Ah, the irony of seeking happiness on the Internet, the procrastination superhighway. Although there is much to be gained, potentially, in taking the time to learn about ways to harness mental resilience, healthy relationships and finding meaning in life, to the extent that this pursuit derails the successful pursuit of our personal projects – in this case Phillip’s medical studies – we really may undermine our happiness. How so? Other research has also demonstrated that the successful pursuit of our goals is a route to happiness (see Goal Progress and Happiness and Getting off to a good start: An upward spiral of happiness ). Procrastination on the other hand is associated with negative emotions, particularly guilt . Avoiding the online procrastination trap Monitor your time on line. Most of us make rational decisions (e.g., it will only take a minute to download that file to my iPod) over irrationally short periods of time (i.e., a minute later, we face the same decision). Without realizing it, hours can slip by as we take the same rational decision – " it will only take a minute "  – one minute at a time. Consider doing the following: Put a clock somewhere prominent to make time salient to you. Set a time limit on your Internet browsing and stick to it. Acknowledge that you are actually taking a break from the task at hand, so that you’re honest with yourself that you’re not really on task anymore even though you’re still at your desk. As Neil Postman has argued so well in books such as Technopoly and Amusing Ourselves to Death , technology is a "double-edged" sword. It takes thought and strategies to use it wisely, even in the pursuit of happiness. © 2009 Psychology Today. This RSS Feed is for personal non-commercial use only.

The High-Functioning Alcoholic: Blog Goals and Intentions

January 18, 2009 in Blogs, Psychology Today by Psychology Today

I have created this blog to increase awareness about high-functioning alcoholics (HFAs) and to help to change the stereotype of the "typical" alcoholic. Alcoholics all suffer from the same disease, but it manifests in different ways. The homeless person and the high-powered executive can both be alcoholics-alcoholism does not differentiate among socioeconomic class, race, education level and appearance. However, because the HFA has the ability to perform and succeed, the treatment often comes too late or not at all. This blog came to fruition as a result of my book Understanding the High-Functioning Alcoholic: Professional Views and Personal Insights to be released March 1, 2009 ( www.highfunctioningalcoholic.com ). Professionally as a therapist, I hope to help others make sense of their own alcoholism or that of a loved one, because they do not fit the "skid row" alcoholic image that remains so pervasive in our society. I want to show that being successful and being alcoholic are not mutually exclusive, but that HFAs need help regardless of their seeming exterior success and functioning. My aim is to help end the denial that so many HFAs and their loved ones have, because these individuals are able to succeed in so many areas of their lives. Personally as a sober alcoholic, a blog such as this and my book are something that I could have used throughout my recovery. I welcome your feedback, questions and discussion around this topic. It is through our stories and truths that lives may be touched and hopefully the seeds of change will be planted. © 2009 Psychology Today. This RSS Feed is for personal non-commercial use only.

Caffeine, hallucinations and an odd ghost obsession

January 16, 2009 in Blogs, Mind Hacks by Vaughan

A recent study hit the headlines reporting a link between caffeine intake and susceptibility to hallucinations. I’ve just read the paper and it’s an interesting well-conducted correlational study, but what struck me was the wackiness of the headlines it generated. The study, led by researcher Simon Jones , was inspired by previous scientific work that has found a link between the stress-related hormone cortisol and psychosis. Caffeine is known to interact with stress to increase cortisol levels further, so the researchers wondered whether there would be a direct link between caffeine intake and psychosis-type changes in thoughts and perception in people without a mental illness. They asked 219 students to fill in well-validated standardised questionnaires relating to caffeine intake, stress, persecutory thoughts and hallucinatory experience and found that caffeine intake was associated with a small but reliable increase in susceptibility to hallucinations. Actually, stress accounted for more hallucination susceptibility than caffeine, but as the first study to show an association between perceptual distortion and the world’s most popular stimulant in healthy people, it’s useful research. I will now recount some of the headlines: Coffee addicts see dead people Caffeine, Responsible For Hallucinations Did You See That Pink Elephant? Too Much Coffee Can Cause You To Freak Out, Man Coffee may make you see ghosts Coffee linked to ‘visions’ ‘Coffeeholics wake the dead’ If you think I’m cherry picking, these are actually fairly typical . The news stories are a strange mix between an obsession with ghosts, which came from God knows where, and a profound confusion between correlation and causation. UPDATE: I notice Bad Science has just picked up on the same study, and the same media obsession with ghosts, but also looks at a common element of the stories claiming that 7 cups of coffee a day ‘triples’ the risk of hallucinations – which didn’t appear in the paper but was apparently sourced from a bit of ad-hoc jiggery pokery for the press-release.

The Miracle of Marriage

January 14, 2009 in Blogs, Psychology Today by Psychology Today

The setting of Jesus’ first miracle-his transmuting water into wine-is a wedding ceremony in Cana. "All marriages take place at Cana," says a faithful Thomas Moore. Therefore all marriages are miracles. At the unhappy end of the spectrum, others join Montaigne, who says, "The land of marriage has this peculiarity, that strangers are desirous of inhabiting it, whilst its natural inhabitants would willingly be banished thence." But it isn’t the marriage that causes the dissatisfaction, it’s the problems of the people involved in the relationship. Marion Solomon, in her book on the power of positive dependency in intimate relationships, identifies these disturbances under the rubrics of defensive dependency, anxious attachment, boundary busting, fragile connection, and defensive distancing. An even greater poison in relationships is the issue of mistrust, earned or not. An old Sufi parable, "The Ancient Coffer," as told in Moore, is a case in point: A very respected man named Nuri Bey had married a much younger woman. A faithful servant reported to him that the wife was behaving suspiciously-sitting alone guarding an old wooden trunk that was big enough to contain a body (i.e., another man). When he asked her to unlock the large chest, she refused to do so because it would mean acceptance of his mistrust. Instead she handed him the key to do so himself. After pondering the situation, Nuri Bey and his servants carried the unopened coffer far away and buried it. What was buried in that cold and lonely place was the soul of their marriage. Most marriages start with some healthy ambivalence but also with good intentions. Two people faithfully enter an arrangement seeking many unspoken, if not unrecognized, fulfillments. They may end up with blissful epiphanies or bitter struggles. If an individual is expecting the partner to actualize his or her potential, that individual will frequently find that the partner falls short of that expectation, especially if the other is suffering from the same illusion. It is probably our idealization of relationships that causes marriage to be so vulnerable. One has to establish a healthy balance. If couples did not expect marriage to be their ultimate source of satisfaction, they would not be so susceptible to its disappointments. However, if their expectations are too low, even the marital relationships of people who relate well will take second place to work (mostly in men), children (mostly in women), or some other primary agenda. Marriage at its best puts couples in a confusing dilemma: the attempt to have a union with someone else while maintaining an independent sense of self. Ambrose Bierce’s Devil’s Dictionary defines marriage as "the state or condition of community consisting of a master, a mistress, two slaves, making in all, two." The more the individual is undifferentiated, the greater the conflict with the partner. Marriage is a fertile ground for individuation as well as for union, but first one must be differentiated, just as a prisoner who wishes to help free his imprisoned companions must first break out of his own chains. Marriage requires attachment and individuation simultaneously, rather than sequentially, as it occurs in our early developmental years. Adapted from The Art of Serenity © 2009 Psychology Today.

Lies Addiction Experts Tell, #2 — alcoholics are addiction experts

January 5, 2009 in Blogs, Psychology Today by Psychology Today

Addiction differs from such DSM-IV disorders as, say, schizophrenia, in that having the condition qualifies a person as an expert. "What alcohol does to me is reality," alcoholics believe, "and so I know all about alcoholism." Susan Cheever, who added her not especially insightful 1999 book, Note Found in a Bottle , to the massive first-person literature on alcoholism, is considered an alcoholism expert. In truth, Ms. Cheevers’ condition actually expresses her, and our cultural, confusion about alcoholism. On a broader scale, Americans believe that the drinking they see around them is how all humans experience alcohol. Human beings are social animals pluperfect. What they and the people they know do is the way the world is. And this myopia is nowhere more apparent than with alcohol. The three major determinants of people’s drinking experiences are: (1) the people they know (friends and family), (2) their social class and cultural group, (3) their historic era. Cheever seems to recognize the social causes of her problem in the New York Times post, Proof , when she described wanton and destructive drinking at the parties she used to frequent. These experiences represented the impact of all major social factors in Cheever’s life – social group, family, historic era. While she and her friends once drank with abandon, however, Cheever and the United States are now undergoing an anti-alcohol cultural wave. That the Times publishes so many Proof posts by recovering alcoholics and active problem drinkers is actually proof of one thing: we are undergoing a national reaction against drinking. Per our current cultural view of addiction, Cheever considers herself an unavoidable victim of the disease of alcoholism – her heritage MADE her an alcoholic. Reviewing her biographical memoir about her father, novelist John Cheever, Home Before Dark , Goodreads declared, "Anyone not convinced of a genetic trait for alcoholism should read this. Cheever’s father, mother and brother were all heavy drinkers if not frank alcoholics." Obviously, therefore, the Cheever family are genetic alcoholics. But this distinctly American view is not consistent with Cheever’s own descriptions, nor with scientific material she relates. In her post to the Proof blog, Cheever describes Bruce Alexander’s famous Rat Park experiment, where animals were habituated to narcotics in an isolated cage, then placed in a large enclosure with other rats and rodent amusements (e.g., a ferris wheel). The addicted rats totally eschewed morphine solution in favor of plain drinking water in Rat Park. This does not support a disease perspective on addictions, as I made clear in The Meaning of Addiction . If simple-minded animals respond to a rich, socially-engaging setting by quitting narcotics cold rat, then how much more likely is human drinking and drug-taking to reflect people’s social milieus? Cheever feels her book will warn others like her of the dangers of alcohol and enable them to avoid the traps she fell into. But the existence of so many similar volumes before hers (including such best-sellers in recent memory as Jill Robinson’s Bed Time Story and Caroline Knapp’s Drinking: A Love Story ) without a notable reduction in alcoholism suggests her hopes won’t be realized. Indeed, remarkably, while Americans drink less currently, more of them report having alcoholic symptoms (with which Americans are now well familiar)! How is this paradox possible? The vision of inescapable alcoholism Cheever depicts is not one that is universally shared – in some cultures the whole idea is completely absent. Here’s the rub – cultures without this image have lower alcoholism rates. In his book The Natural History of Alcoholism , George Vaillant found when following the lives of inner-city Boston men from adolescence to seniority that Irish-Americans in his sample were almost ten times as likely to become alcoholic as their Italian, Jewish, and Greek neighbors! The Irish Americans Vaillant studied had an extravagant view of alcohol. According to Vaillant: "It is consistent with Irish culture to see the use of alcohol in terms of black or white, good or evil, drunkenness or complete abstinence." Conveying the idea of alcohol’s irresistible power, and in fact drinking that way, is to convince people their drinking is uncontrollable and to encourage such drinking. Here’s the irony: to the extent that people read and believe views like Cheever’s – make them a part of their internal baggage like they are a part of Cheever’s – they will be susceptible to alcoholism. © 2009 Psychology Today.

Understanding numbers: let me count the ways

December 31, 2008 in Blogs, Mind Hacks by Vaughan

The latest edition of The Economist has an interesting article about whether our ability to count and estimate quantity is an innate ability that we have from birth. The article covers studies on babies, people who speak languages that only have number words for “one”, “two”, “few” and “many”, people who have never developed certain maths skills and others who have lost specific number abilities after brain injury: Lisa Cipolotti , a neuropsychologist, studied a Signora Gaddi, who used to run a hotel and keep its accounts. After a stroke she could find the number of things in a small group only by counting—when asked how many arms a crucifix had, she got Dr Cipolotti to hold out her arms so she could count them. Signora Gaddi’s problems seemed to affect only numbers. She could still read, speak and reason, remember historical and geographical facts, and order objects by their physical size. In fact, Signora Gaddi’s difficulties went even deeper than Charles’s. The stroke which damaged her innate understanding of small numbers also robbed her of the entire numerical edifice built on that foundation. For her, numbers stopped at four. When asked to count up from one, she got to four and no further. If there were more than four dots on a page she could not count them. She could not say how old she was or how many days were in a week, or even tell the time. Link to Economist article ‘Easy as 1, 2, 3′.

Is this the end of the mystery of self-awareness?

December 30, 2008 in Blogs, Mind Hacks by Vaughan

Edge has an interesting essay by V.S. Ramachandran arguing that while we may not be any closer to understanding consciousness, an understanding of the neuroscience of ‘the self’ may be within our grasp as demonstrated by studies showing how our perception of self-awareness breaks down in curious ways after brain injury. There are lots of wonderful examples of how the self can become warped, but I’m not sure that it is entirely held together with Ramachandran’s long held enthusiasm for the explanatory power of mirror neurons. However, it’s an entertaining and provocative read and well worth your time despite, and probably because of, the somewhat expansive tone in places. There is one odd section though, the second section of bullet-pointed text, where he refers to the “anterior cumulate” which almost certain should refer to the frontal brain area the ‘ anterior cingulate ‘, as the anterior cumulate doesn’t exist (an example of Bell’s Frontal Nomenclature Hypertrophy syndrome I wonder?). Following that paragraph is another where he suggests akinetic mutism is the lack of visual consciousness, which is exactly what it isn’t. In fact, it’s the inability to independently initiate action without external prompting, linked to anterior cingulate damage, and one of the defining features is that the problems are not caused by visual impairments. Link to Edge on ‘Self Awareness: The Last Frontier’.

New book on the psychology and engineering of traffic

December 23, 2008 in Blogs, Cognitive Daily by Cognitive Daily

Two summers ago in Paris, I was astounded at the volume of traffic that somehow managed to negotiate the traffic circle at the Arc de Triomphe without incident. Here’s the (poor quality) video I made to document traffic flow there: I learned to drive in my 20s in New York City. Like Paris, New York has a traffic rhythm all its own, where lane markings are mere suggestions. In New York, parking is tolerated nearly anywhere, as long as traffic isn’t unduly impeded. I’ve seen people double-parked, triple-parked, parked on corners, on sidewalks, you name it. Driving into Manhattan several times a week also helped me developed what I liked to call “highway justice” — the sense that if someone did something “unjust” as a driver, they would deserve whatever punishment the others meted out to them in traffic. The biggest injustices in New York always seemed to revolve around highway merges. If traffic was merging onto a busy highway, justice dictated that they should be allowed in every-other-car. If mergers tried to double up, or if highway drivers didn’t allow cars in, they were violators who deserved to be punished (although I was smart enough not to attempt to mete out this justice myself). But it was completely acceptable to wait until the last second to merge (if, for example, a lane was closing ahead due to construction). Highway space was at a premium, so why not use it all? Once I moved to North Carolina, however, I soon learned there was a very different sense of justice. Late merging and horn-honking were considered rude, and the worst injustice was driving too slowly in the left lane. So which justice system is better — North Carolina’s, or New York’s (or Paris’)? Surely science has something to say about all this. Of course it does, and Tom Vanderbilt does a fantastic job negotiating through the vast array of studies about traffic and driver behavior in his book Traffic: Why We Drive the Way We Do .
