How Ivan Pavlov Handled a Piece of Steak

Most psychology students recognize the name of Ivan Pavlov, one of the great minds of psychology, who developed the theory of classical conditioning (dogs salivating when he rang a bell). From the Yale Alumni magazine comes this wonderful tidbit of a story:

“In mid-August 1929, the Harvard Medical School hosted the Thirteenth International Physiological Congress, one of the largest gatherings of scientists ever convened in the United States. Pavlov, the doyen of experimental physiology at almost 80 and honored by a Nobel Prize a quarter-century earlier, was the lion of the gathering. His pioneering work on conditioned reflexes had been crucial to understanding brain function, and he was keen to see the Harvard neurosurgeon Harvey Cushing ’91 operate. The preeminent brain surgeon and father of modern neurosurgery as a field, Cushing, two decades younger than Pavlov, was at the top of his game. Performing for Pavlov in a theater at the Peter Bent Brigham Hospital, Cushing removed a large tumor of the left hemisphere from a cancer patient’s brain. The patient later recalled that Cushing introduced him to Pavlov, saying, “You are now shaking hands with the world’s greatest living physiologist.”

Pavlov was captivated by the new electrosurgical knife Cushing used in the operation, and at the end of the procedure, Cushing got a piece of beef so that the elder scientist could try his hand. After making a few incisions, Pavlov inscribed his name into the meat. “I asked him whether he wanted me to eat the meat in the hope of improving my conditional reflexes,” Cushing wrote in his journal, “or whether we could keep it in the museum, the latter we will proceed to do—’Pavlov’s beef-steak.'” A collector of old medical books and of brain tumors, when he died in 1939 Cushing bequeathed both to Yale, where his rare books would become the cornerstone for creating the Medical Historical Library.”

Anyway, I love this story, especially the concept of him eating the steak, to “improve his conditional reflexes!”

Next time I throw a barbecue party I’ll serve the Pavlov-Steak sandwich…

New Study Suggests You Can Reprogram Your Brain in Four Days!

Many previous studies have shown through the use of neuroimaging that meditation can change the brain. But most of those studies have looked at medium to long-term meditators. Some looked at monks who had meditated for decades, and some looked at new meditators who had meditated daily for 6 to 8 weeks. At least this much meditation practice was thought to be necessary to create measurable changes in the brain.

But a new study at the University of North Carolina at Charlotte suggests that brain changes may happen much more quickly, in as few as four days!

Student volunteers were randomly assigned to either practice mindfulness meditation or listen to the reading of JRR Tolkien’s The Hobbit, for 20 minutes a day, for four days. The groups were tested using behavioral tests of mood, memory, visual attention, attention processing, and vigilance. The meditative practice was a simple mindfulness technique.  Participants were told to focus on their breath, and that when thoughts distracted them to notice the thought, and then refocus on the breathing.

What were the results? Both groups improved in mood, but only the meditation group improved in cognitive measures. In one challenging mental task, the meditation group did 10 times better than the reading group. It appeared that meditation improved the ability to sustain attention and vigilance.

This is an exciting study which hopefully will be replicated and expanded with their neuroimaging to see if there are functional or structural brain changes after brief meditation practice.

To summarize, it appears that a brief four-day practice of mindfulness meditation can significantly improve cognitive functioning that is related to attention and vigilance.

How lasting is this effect? Does it wear off in hours, days, etc.? What is the dose response ratio of meditation to cognitive functioning improvement? For instance, would eight days of meditation practice create even more cognitive improvement?

In any case, it’s worth practicing meditation at least briefly to see its effects on your mind and your emotions. Commit to 20 minutes a day for one week, and see what happens for you.

Now I’m off to meditate…

Does Money Buy Happiness? No, And The Answer Of What Does Buy Happiness May Surprise You

Posted on by

It is often said that money can buy happiness, and as I’ve blogged in earlier articles, this is true, but only up to a basic middle-class economic status. Above that, money doesn’t seem to add much happiness. (See my posts here and here.)happiness

So what does buy happiness? We have a surprising answer from our friends across the pond, at the University of Warwick in England. A new study published online Nov. 18 in the journal Health Economics, Policy and Law surveyed thousands of people on their levels of happiness and correlated it with external factors such as a pay raise or winning a lottery prize, and compared this to receiving psychotherapy.  Astonishingly, even to me, a psychologist, the increase in happiness from a $1329 course of therapy was so large that to equal it people had to get a pay raise of more than $41,542! That’s a ratio of 32 times! That means a dollar spent on therapy boosts happiness 32 times more than the same dollar received in a pay raise or lottery prize.

As the study author Chris Boyce, of the University of Warwick, summarized:  “Often the importance of money for improving our well-being and bringing greater happiness is vastly over-valued in our societies. The benefits of having good mental health, on the other hand, are often not fully appreciated and people do not realize the powerful effect that psychological therapy, such as non-directive counseling, can have on improving our well-being.”

Bravo, Chris! Now when patients ask me whether therapy is worth the money, I can confidently say that research suggests it might be one of the best investments you can make in yourself and your own happiness. (And it’s okay to get a raise, as long as you spend it on therapy!)

The only problem I can see with this article being published is that it may lower MY happiness, as I might get busier, perhaps earning more money, but not having time to see my own therapist!

So to answer the original question, does money buy happiness? Money doesn’t buy happiness; it buys psychotherapy, which yields 32 times more happiness than money!

Why do Most Psychologists Ignore Science Based Therapy? Evidence Based Psychotherapy and the Failure of Practicioners

Posted on by

A new article in Newsweek magazine titled Ignoring the Evidence documents how most psychologists ignore scientific evidence about treatments such as cognitive behavioral therapy which have been proven to be effective.

A two-year study which is going to be published in November in Psychological Science in the Public Interest, found that most psychologists “give more weight to their personal experiences then to science.”

The Newsweek article has a wonderful quote,

“Thanks to clinical trials as rigorous as those for, say, cardiology, we now know that cognitive and cognitive-behavior therapy (teaching patients to think about their thoughts in new, healthier ways and to act on those new ways of thinking) are effective against depression, panic disorder, bulimia nervosa, obsessive-compulsive disorder, and -posttraumatic-stress disorder, with multiple trials showing that these treatments-the tools of psychology-bring more durable benefits with lower relapse rates than drugs, which non-M.D. psychologists cannot prescribe. Studies have also shown that behavioral couples therapy helps alcoholics stay on the wagon, and that family therapy can help schizophrenics function. “


The article documents how most psychologists fail to provide empirically proven treatment approaches and instead use methods which are often ineffective. The truth is there is very little evidence for most of the types of therapy commonly performed in private practices by psychologists and by Masters level therapists. If you are shopping for the most effective types of therapy you need to find a practitioner who is skilled at cognitive behavioral therapy (CBT) which is one of the few psychotherapy approaches that has been proven to work on a variety of problems.

Another interesting article in Newsweek about evidence-based treatment discussed bulimia. Here’s the summary:

“On bulimia (which affects about 1 percent of women) and binge eating disorders (2 to 5 percent), the verdict is more optimistic: psychological treatment can help a lot, and cognitive behavioral therapy (CBT) is the most effective talk therapy. That’s based on 48 studies with 3,054 participants. CBT (typically, 15 to 20 sessions over five months) helps patients understand their patterns of binge eating and purging, recognize and anticipate the triggers for it, and summon the strength to resist them; it stops bingeing in just over one third of patients. Interpersonal therapy produced comparable results, but took months longer; other therapies helped no more than 22 percent of patients. If you or someone you love seeks treatment for bulimia, and is offered something other than CBT first, it’s not unreasonable to ask why. Cynthia Bulik, director of the University of North Carolina Eating Disorders Program, summarized it this way: “Bulimia nervosa is treatable; some treatment is better than no treatment; CBT is associated with the best outcome.”

So the bottom line is this:

1. Most psychologists who don’t practice Cognitive Behavioral Therapy (CBT) are just winging it, using treatments that haven’t been shown to work by scientific studies. It’s as if you went to a regular physician and got treatment with leaches!

2. Many psychologists claim to use CBT but haven’t really trained in the use of CBT, or have taken a weekend workshop. Unless they prescribe weekly homework that involves writing down thoughts, and learning skills to analyze and change your thoughts, then they aren’t really doing CBT, and I recommend you find someone else.

3. If you have an anxiety disorder, depression, bulimia, or obsessive compulsive disorder, and haven’t been offered CBT, then you are not receiving state of the art treatment.

How to Deal with Teenage Depression: A New Study of Adolescent Depression and its Treatment

A new study reported in the Journal of the American Academy of Child and Adolescent Psychiatry found some interesting results of a study of teenage depression and its treatment.

This study of 439 teenage children with major depression, done at the University of Texas Southwestern Medical Center at Dallas tested anti-depressant medication (fluoxetine or Prozac), cognitive behavioral therapy (CBT), and a combination of both (COMB). They found that only 23% of the patients had their depression cured by 12 weeks of therapy. But 9 months of therapy was much more effective, with 60 percent going into remission.

The bad news though is that this means that almost half of the teenagers (40%) were still depressed after 9 months of therapy.

The good news is in terms of relapse. Of those who responded quickly to treatment, two-thirds retained the benefits of treatment over 9 months. The same was true of those who took longer to respond.

Which treatment was better? That is an interesting picture.

It depends at which time point you are looking at. At 12 weeks, the results for percentage fully remitted (cured) of depression were: combined drug and CBT therapy (37%), drug therapy only (23%), and CBT therapy only (16%). The combined therapy was significantly better than the other therapies. But note that overall, only 23% of the teenagers had recovered at 12 weeks, which means that 77% were still suffering!

But at nine months the outcomes look quite different. The combination therapy is still the best, but by less of a margin. The results for remission at at 9 months were: combination, 60%; drug, 55%; cognitive-behavioral therapy, 64%; and overall, 60%. By 24 weeks all the treatments were working well. But a full 40% of the teenagers were still depressed.

So the right answer to the question of which treatment works better is neither. Both drugs and cognitive behavioral therapy were equally effective, over the long term. But the combination of both was worked more quickly. As the researchers said, “choosing just one therapy might delay many teenagers’ recovery by 2 or 3 months.” As the saying goes, candy is dandy, but liquor is quicker, and we might conclude that drugs or CBT are dandy, but combined therapy is quicker.

So what does this mean to parents of depressed teenagers? Here are my takeaway messages:

  1. Don’t expect treatment for depression to work quickly. It may take more than 9 months of weekly treatment before your teenager responds to therapy. This means at least 40 sessions of therapy.
  2. Be patient, and set reasonable expectations for both yourself and for your child. Tell them that therapy will help, but it may take a while. Let support networks such as school counselors or trusted teachers know to be patient.
  3. Although medications and cognitive behavioral therapy were equally effective in the long run, the combination of both tended to work much more quickly. So if you can afford it, and have access to good practitioners who do cognitive behavioral therapy, use both.
  4. Be aware that in other studies, the relapse rate for medication treatment of depression was significantly higher than for cognitive behavioral therapy, once the medications are discontinued. So choosing medications only may increase the risk that your teenager will relapse into depression.
  5. Be aware that much teenage depression can be a reaction to social environments. This includes the family, the school, and peers. Be sure that your teen’s therapist is attuned to family, school, and peer issues. They should meet with the whole family at least several times.
  6. Take teenage depression seriously. It’s not just a phase. Teenage depression, when serious, can greatly increase the risk of suicide. All suspected depression should be evaluated by a professional and treated if present.
