In today’s show, adapted from an article published on the Oscar Web site written by Amber Davis, we look at UVA psychologist Amori Yee Mikami, her research of ADHD, and how intervening factors have made this disorder more complex and detrimental for young females.

In studies conducted on the effects of Attention Deficit Hyperactivity Disorder in young children, researchers often turn to the most likely exhibitors of the impulsive and aggressive behaviors associated with the ailment — young males. What University of Virginia psychologist Amori Yee Mikami sought to uncover in researching ADHD, however, were the intervening factors that made this disorder more complex and detrimental for young females.

Mikami said, “We know a lot about boys with ADHD, partially because the disorder is three times more common in boys. Many research studies on ADHD have focused on how the disorder affects young boys. What I became interested in was how ADHD affected girls’ behaviors, particularly in adolescence.”

Since her original research at the University of California Berkley — where she found evidence supporting the hypothesis that ADHD contributes to social isolation — Mikami has focused on untangling the gender differences in children suffering with ADHD. Her most recent study, published in the Journal of Abnormal Psychology, concludes that girls with ADHD are at a greater risk for the binge eating and purging behaviors associated with bulimia nervosa.

Mikami said, “We know that children with ADHD have increased risk for delinquency, aggressive behavior problems, drug use and depression in adolescence, and now this study suggests they may also be at risk for an eating disorder problem. Since eating disorders are 10 times more common in females, and the effects of ADHD on girls are not as widely understood, the link between eating disorders and ADHD may have gone unnoticed or untreated.”

According to Mikami, the impulsive behaviors common in ADHD can make it difficult to maintain healthy eating habits and a healthy weight, leading girls to become self-conscious about their body image. Meanwhile, current ADHD medications on the market such as Ritalin may actually exacerbate the problem.

Mikami, who is currently conducting research to determine potential effects of these medications on bulimia nervosa symptoms said, “These drugs tend to make youth a little thinner because a common side effect of stimulant medications is appetite suppression. What I’m testing is whether this medicine is something that might discourage or encourage eating disorder problems.”

Mikami’s research plans include studying whether young males with ADHD have similar potential to develop eating disorders.

In addition to her ongoing research, Mikami oversees the “Friendship Clinic” in Charlottesville, which offers children with ADHD and their parents an eight-week program in which both parents and children learn how to cope with the disorder together. The clinic allows Mikami to observe how children with ADHD interact with their peers while introducing them to an environment that encourages typical social behavior.

Mikami said, “Early intervention is one of the most effective ways to combat the negative effects of ADHD. Girls with ADHD are often teased and rejected by their peers. Childhood peer problems seem to predict eating disorder symptoms in adolescence. Getting parents and teachers involved might help prevent these instances.”

How did you react the last time you had a fight with that significant someone in your life? With couples, the woman might apologize, or the man might make a joke or express understanding. By doing this, they subtly and briefly lighten the tension as they work their way through a disagreement.

Psychology Professor James Coan discovered a long time ago that by doing this, even when couples fight, they take care of each other. This interplay was significant when Coan designed a study exploring what happens in people’s brains when they behave emotionally or observe other people’s emotions. Coan said, “what we are learning is our emotions are more heavily involved in our day-to-day physical health than we previously thought.

How we deal with our relationships is closely tied to how long we live, how frequently we go to the doctor, how rapidly we recover from injury, how happy we tend to be in our lives.” With his colleagues, Hillary Schaefer and Richard J. Davidson from the University of Wisconsin, Coan sought to demonstrate the neurobiological basis of emotional expression and regulatory processes.

In the study, they used MRI technology to view these responses at the level of glucose metabolism and blood oxygenation in the brain. Because of the importance of emotional connectedness to the study, 16 happily married, heterosexual couples were recruited as test subjects. Wives were placed in the scanner so brain activity could be recorded as each was exposed to the anxiety-producing possibility of an electric shock to the ankle.

Researchers wanted to see what effect different types of emotional support would have in areas of the brain related to the body’s normal fight-or-flight stress response. Readings were taken when the woman was alone in facing this challenge, When a stranger, a male, was present to support her And when her husband offered support. Coan stated, “the scanning environment is pretty hostile to looking at interactions between people.” The MRI machine surrounds the subject’s body and restricts movement. The women weren’t even able to see the support person during the scanning process.

Having the man offer his hand for the woman to hold was about the only intervention possible in this setting. Not surprisingly, the results show there was a healthy reduction in the stress response when test subjects were supported. Stimulation in the regions of the brain that regulate physiological arousal and coordinate large muscles and joints was significantly decreased, no matter who was holding the woman’s hand. However, when it was her husband’s hand she was holding, the response was significantly greater.

Coan said, “When you’re holding a spouse’s hand, you get down-regulation in all of those same systems. But all the other systems that have to do with the conscious regulation of your emotions — having to pay attention to what’s happening with your body and having to become more vigilant for future dangers — all of these other systems come down as well. Your brain doesn’t work as hard when it’s your spouse. What surprised Coan and his colleagues most was the relaxation response demonstrated by what they called “super couples.” In those couples with exceptionally high-quality relationships, “Hand-holding had a significantly greater effect on soothing their brains.”

Tests showed differences involving two structures that were not affected at all in other test subjects. They observed evidence of reduced release of stress hormones by the hypothalamus. These hormones are responsible for inhibiting immune response and other activities that have critical implications for health and well-being.

Of greater interest was the reduction of activity in the right anterior insula. This brain structure modulates the amount of pain stimulus one experiences subjectively. Reduction of activity in this area means test subjects actually felt less pain when they held their husband’s hand.

So it can be said, having someone you love hold your hand really can take the hurt away.


The Happiness Hypothesis

When social psychologist University of Virginia in 1995, he prepared by reading Thomas Jefferson’s writings and making the requisite pilgrimage to Monticello. Little did he realize the impact this Jeffersonian indoctrination would have on his own research.

Haidt’s area of specialization is moral emotions, but before coming to U.Va., he focused his studies on cross-cultural experiences of disgust. He read ancient Buddhist texts and spent time in India, exploring how the beneficial biological aspects of disgust became codified as religious imperatives and keys to social order. 

Then he came across Thomas Jefferson’s letter to Robert Skipwith, in which Jefferson describes how “witnessing acts of beauty and moral goodness — whether in literature or reality — swells the chest and inspires a desire to lead a better life.”  Suddenly Haidt began thinking about the antithesis of disgust, the psychological effect of uplifting experiences, an emotion he termed “elevation.” Haidt said,“That letter fundamentally changed the course of my research.” 

In a moment of zeitgeist, Haidt’s inquiry into elevation coincided with the burgeoning of the academic field, positive psychology, which studies how people find meaning and happiness in life. His research into what prompts elevation and the resulting physical and motivational effects won him psychology’s largest monetary award, the John Templeton Prize for Positive Psychology, in 2001.

While researching elevation, Haidt continued teaching a large undergraduate survey course introducing the study of psychology. In the classroom, he has found it useful to cite quotations and examples from ancient philosophy and world religion to make his points more memorable. Haidt’s colleague, psychology professor Gerald Clore stated, “This penchant for asking what it all means makes him very appealing as an undergraduate lecturer in Introductory Psychology.”

Having received several university and state awards for teaching, Haidt decided to apply his ancient wisdom approach to a study of happiness. Looking at the relationship between what religious and philosophical traditions say about fulfillment and what scientists have discovered about the biological processes involved in the brain’s response to stimuli, Haidt gleaned 10 psychological truths from ancient religious and philosophical texts, which he examines in the 10 chapters of his 2006 book, The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom.

Throughout the work, Haidt analogizes the conscious mind to a rider straddling the elephant of the unconscious mind, trying to guide the giant beast where the rider wants it to go. He cited numerous psychological experiments that demonstrate how at odds the conscious and unconscious minds often are, despite the conscious mind’s skill at rationalizing choices and behavior. His book suggests that by understanding ancient wisdom’s insights into our divided nature, we have a chance of establishing a more harmonious relationship between the conscious and unconscious, gently training our elephants to do as we wish.

Haidt, who has also established an accompanying website, Happinesshypothesis.com , said, “every good idea I’ve ever had in my life is in this book, the book is really a gateway to everything I want to work on for the rest of my life.”  Although Haidt spent 2005-2006 at Princeton University as the Laurence S. Rockefeller Visiting Professor of Ethics at the Center for Human Values, his heart remains in Charlottesville. Haidt said,“it really was because of U.Va., because of Jefferson, that I came to study this completely neglected area of emotion.”

Haidt is currently studying the foundations of moral judgment in liberals and conservatives in order to understand how political appeals might be better crafted. In addition, he’s researching how the application of elevation can be used to increase trust in relationships, especially among married couples.
