“Willy Wonky & The Chocolate Fetish”: Why Do Depressed People Eat More Chocolate?
People who are depressed appear to eat more chocolate than those who aren’t
Researchers at UC San Diego and UC Davis examined chocolate consumption and other dietary intake patterns among 931 men and women who were not using antidepressants. The participants were also given a depression screening test. Those who screened positive for possible depression consumed an average of 8.4 servings of chocolate — defined as one ounce of chocolate candy — per month. That compared with 5.4 servings per month among people who were not depressed.
Those who scored highest on the mood tests, indicating possible major depression, consumed an average of 11.8 servings per month. The findings were similar among women and men.
When the researchers controlled for other dietary factors that could be linked to mood — such as caffeine, fat and carbohydrate intake — they found only chocolate consumption correlated with mood.
It’s not clear how the two are linked, the authors wrote. It could be that depression stimulates chocolate cravings as a form of self-treatment. Chocolate prompts the release of certain chemicals in the brain, such as dopamine, that produce feelings of pleasure.
There is no evidence, however, that chocolate has a sustained benefit on improving mood. Like alcohol, chocolate may contribute a short-term boost in mood followed by a return to depression or a worsened mood. A study published in 2007 in the journal Appetite found that eating chocolate improved mood but only for about three minutes.
It’s also possible that depressed people seek chocolate to improve mood but that the trans fats in some chocolate counteract the effect of omega-3 fatty acid production in the body, the authors said in the paper. Omega-3 fatty acids are thought to improve mental health.

Another theory is that chocolate consumption contributes to depression or that some physiological mechanism, such as stress, drives both depression and chocolate cravings.
“It’s unlikely that chocolate makes people depressed,” said Marcia Levin Pelchat, a psychologist who studies food cravings at the Monell Chemical Senses Center in Philadelphia. She was not involved in the new study. “Most people believe the beneficial effects of chocolate are on mood and that they are learned. You eat chocolate; it makes you feel good, and sometime when you’re feeling badly it occurs to you, ‘Gee, if I eat some chocolate I might feel better.’ ”
Chocolate is popular in North America and Britain, she said. But in other cultures, different foods are considered pleasure-inducing pick-me-ups.
“In the United States, people consider chocolate really tasty,” Pelchat said. “It has a high cultural value. It’s an appropriate gift for Valentine’s Day. But in China, you might give stuffed snails to someone you really like.”

All By Myself…The Tyranny of The Loneliness Epidemic
Credit Dr Ronald Pies, M.D. via psychcentral.com
The recent controversy over the still-developing DSM-5 — that compendium of mental disorders the media love to call, inappropriately, “The Bible of Psychiatry” –has gotten me thinking about loneliness. Now, thankfully, nobody has seriously proposed including loneliness in the DSM-5. Indeed, loneliness is usually thought of as simply an unpleasant part of life — one of the “slings and arrows” that pierce almost all of us from time to time. Loneliness, in some ways, remains enmeshed in a web of literary and cultural clichés, born of such works as Nathaniel West’s darkly comic novel, Miss Lonelyhearts, and the Beatles’ whimsical anthem, “Sgt. Pepper’s Lonely Hearts Club Band.”
But loneliness turns out to be a serious matter. And as psychiatry debates the diagnostic minutiae of DSM-5, all of us may need to remind ourselves that millions in this country struggle against the downward tug of loneliness. Yet even among health care professionals, few seem aware that loneliness is closely linked with numerous emotional and physical ills, particular among the elderly and infirm.
It’s easy to assume that loneliness is simply a matter of mind and mood. Yet recent evidence suggests that loneliness may injure the body in surprising ways. Researchers at the University of Pittsburgh School of Medicine studied the risk of coronary heart disease over a 19-year period, in a community sample of men and women. The study found that among women, high degrees of loneliness were associated with increased risk of heart disease, even after controlling for age, race, marital status, depression and several other confounding variables. (In an email message to me, the lead author, Dr. Rebecca C. Thurston, PhD, speculated that the male subjects might have been more reluctant to acknowledge their feelings of loneliness).
Similarly, Dr. Dara Sorkin and her colleagues at the University of California, Irvine, found that for every increase in the level of loneliness in a sample of 180 older adults, there was a threefold increase in the odds of having heart disease. Conversely, among individuals who felt they had companionship or social support, the likelihood of having heart disease decreased.
The young, of course, are far from immune to loneliness. Researchers at Aarhus University in Denmark studied loneliness in a population of adolescent boys with autism spectrum disorders (an area of great controversy in the proposed DSM-5 criteria). More than a fifth of the sample described themselves as “often or always” feeling lonely—a finding that seems to run counter to the notion that those with autism are emotionally disconnected from other people. Furthermore, the study found that the more social support these boys received, the lower their degree of loneliness. We have no cure for autism in adolescents–but the remedy for loneliness in these kids may be as close as the nearest friend.
And lest there be any doubt that loneliness has far ranging effects on the health of the body, consider the intriguing findings from Dr. S.W. Cole and colleagues, at the UCLA School of Medicine. These researchers looked at levels of gene activity in the white blood cells of individuals with either high or low levels of loneliness. Subjects with high levels of subjective social isolation—basically, loneliness — showed evidence of an over-active inflammatory response. These same lonely subjects showed reduced activity in genes that normally suppress inflammation. Such gene effects could explain reports of higher rates of inflammatory disease in those experiencing loneliness.

Could inflammatory changes, in turn, explain the correlation between loneliness and heart disease? Inflammation is known to play an important role in coronary artery disease. But loneliness by itself may be just one domino in the chain of causation. According to Dr. Heather S. Lett and colleagues at Duke University Medical Center, the perception of poor social support — in effect, loneliness — is a risk factor for development, or worsening, of clinical depression. Depression may in turn bring about inflammatory changes in the heart that lead to frank heart disease. This complicated pathway is still speculative, but plausible.
Loneliness, of course, is not synonymous with “being alone.” Many individuals who live alone do not feel “lonely.” Indeed, some seem to revel in their aloneness. Perhaps this is what theologian Paul Tillich had in mind when he observed that language “… has created the word “loneliness” to express the pain of being alone. And it has created the word “solitude” to express the glory of being alone.” Conversely, some people feel “alone” or disconnected from others, even when surrounded with people.
Let’s admit that not everybody is capable of experiencing the “glory of being alone” or of transforming loneliness into “solitude.” So what can a socially-isolated person do to avoid loneliness and its associated health problems? Joining a local support group can help decrease isolation; allow friendships to form; and give the lonely person an opportunity both to receive and to provide help. This reciprocity can bolster the lonely person’s ego and improve overall well-being. Support groups geared to particular medical conditions can also help reduce disease-related complications. Although there are always risks in going “on line” to find support, Daily Strength appears to be a legitimate and helpful website for locating support groups of all types, including those for loneliness. Psych Central also provides opportunities to exchange ideas and “connect” with many individuals who feel isolated or alone. For those who feel lonely even in the midst of friends, individual psychotherapy may be helpful, since this paradoxical feeling often stems from a fear of “getting close” to others.
No, loneliness is not a disease or disorder. It certainly shouldn’t appear in the DSM-5 — but it should be on our minds, as a serious public health problem. Fortunately, the “treatment” may be as simple as reaching out to another human being, with compassion and understanding.

Winners Are Grinners: Even If There’s Nothing to Win!
Whether it’s for money, marbles or chalk, the brains of reward-driven people keep their game faces on, helping them win at every step of the way. Surprisingly, they win most often when there is no reward.
That’s the finding of neuroscientists at Washington University in St. Louis, who tested 31 randomly selected subjects with word games, some of which had monetary rewards of either 25 or 75 cents per correct answer, others of which had no money attached.
Subjects were given a short list of five words to memorize in a matter of seconds, then a 3.5-second interval or pause, then a few seconds to respond to a solitary word that either had been on the list or had not. Test performance had no consequence in some trials, but in others, a computer graded the responses, providing an opportunity to win either 25 cent or 75 cents for quick and accurate answers. Even during these periods, subjects were sometimes alerted that their performance would not be rewarded on that trial.
Prior to testing, subjects were submitted to a battery of personality tests that rated their degree of competitiveness and their sensitivity to monetary rewards.
Designed to test the hypothesis that excitement in the brains of the most monetary-reward-sensitive subjects would slacken during trials that did not pay, the study is co-authored by Koji Jimura, PhD, a post-doctoral researcher, and Todd Braver, PhD, a professor, both based in psychology in Arts & Sciences. Braver is also a member of the neuroscience program and radiology department in the university’s School of Medicine.
But the researchers found a paradoxical result: the performance of the most reward-driven individuals was actually most improved – relative to the less reward-driven – in the trials that paid nothing, not the ones in which there was money at stake.
Even more striking was that the brain scans taken using functional Magnetic Resonance Imaging (fMRI) showed a change in the pattern of activity during the non-rewarded trials within the lateral prefrontal cortex (PFC), located right behind the outer corner of the eyebrow, an area that is strongly linked to intelligence, goal-driven behavior and cognitive strategies. The change in lateral PFC activity was statistically linked to the extra behavioral benefits observed in the reward-driven individuals.
The researchers suggest that this change in lateral PFC activity patterns represents a flexible shift in response to the motivational importance of the task, translating this into a superior task strategy that the researchers term “proactive cognitive control.” In other words, once the rewarding motivational context is established in the brain indicating there is a goal-driven contest at hand, the brain actually rallies its neuronal troops and readies itself for the next trial, whether it’s for money or not.
“It sounds reasonable now, but when I happened upon this result, I couldn’t believe it because we expected the opposite results,” says Jimura, first author of the paper. “I had to analyze the data thoroughly to persuade myself. The important finding of our study is that the brains of these reward- sensitive individuals do not respond to the reward information on individual trials. Instead, it shows that they have persistent motivation, even in the absence of a reward. You’d think you’d have to reward them on every trial to do well. But it seems that their brains recognized the rewarding motivational context that carried over across all the trials.”

The finding sheds more light on the workings of the lateral PFC and provides potential behavioral clues about personality, motivation, goals and cognitive strategies. The research has important implications for understanding the nature of persistent motivation, how the brain creates such states, and why some people seem to be able to use motivation more effectively than others. By understanding the brain circuitry involved, it might be possible to create motivational situations that are more effective for all individuals, not just the most reward-driven ones, or to develop drug therapies for individuals that suffer from chronic motivational problems.Their results are published April 26 in the early online edition of the Proceedings of the National Academy of Science.
Everyone knows of competitive people who have to win, whether in a game of HORSE, golf or the office NCAA basketball tournament pool. The findings might tell researchers something about the competitive drive.
The researchers are interested in the signaling chain that ignites the prefrontal cortex when it acts on reward-driven impulses, and they speculate that the brain chemical dopamine could be involved. That could be a potential direction of future studies. Dopamine neurons, once thought to be involved in a host of pleasurable situations, but now considered more of learning or predictive signal, might respond to cues that let the lateral PFC know that it’s in for something good. This signal might help to keep information about the goals, rules or best strategies for the task active in mind to increase the chances of obtaining the desired outcome.
In the context of this study, when a 75-cent reward is available for a trial, the dopamine-releasing neurons could be sending signals to the lateral PFC that “jump start” it to do the right procedures to get a reward.
“It would be like the dopamine neurons recognize a cup of Ben and Jerry’s ice cream, and tell the lateral PFC the right action strategy to get the reward – to grab a spoon and bring the ice cream to your mouth,” says Braver. “We think that the dopamine neurons fires to the cue rather than the reward itself, especially after the brain learns the relationship between the two. We’d like to explore that some more.”
They also are interested in the “reward carryover state,” or the proactive cognitive strategy that keeps the brain excited even in gaps, such as pauses between trials or trials without rewards. They might consider a study in which rewards are far fewer.
“It’s possible we’d see more slackers with less rewards,” Braver says. “That might have an effect on the reward carryover state. There are a host of interesting further questions that this work brings up which we plan to pursue.”

Remember What Happened? Only In Your Dreams!
It is by now well established that sleep can be an important tool when it comes to enhancing memory and learning skills. And now, a new study sheds light on the role that dreams play in this important process.
Led by scientists at Beth Israel Deaconess Medical Center (BIDMC), the new findings suggest that dreams may be the sleeping brain’s way of telling us that it is hard at work on the process of memory consolidation, integrating our recent experiences to help us with performance-related tasks in the short run and, in the long run, translating this material into information that will have widespread application to our lives. The study is reported in the April 22 On-line issue of Current Biology.
“What’s got us really excited, is that after nearly 100 years of debate about the function of dreams, this study tells us that dreams are the brain’s way of processing, integrating and really understanding new information,” explains senior author Robert Stickgold, PhD, Director of the Center for Sleep and Cognition at BIDMC and Associate Professor of Psychiatry at Harvard Medical School. “Dreams are a clear indication that the sleeping brain is working on memories at multiple levels, including ways that will directly improve performance.”
At the outset, the authors hypothesized that dreaming about a learning experience during nonrapid eye movement (NREM) sleep would lead to improved performance on a hippocampus-dependent spatial memory task. (The hippocampus is a region of the brain responsible for storing spatial memory.)
To test this hypothesis, the investigators had 99 subjects spend an hour training on a “virtual maze task,” a computer exercise in which they were asked to navigate through and learn the layout of a complex 3D maze with the goal of reaching an endpoint as quickly as possible. Following this initial training, participants were assigned to either take a 90-minute nap or to engage in quiet activities but remain awake. At various times, subjects were also asked to describe what was going through their minds, or in the case of the nappers, what they had been dreaming about. Five hours after the initial exercise, the subjects were retested on the maze task.
The results were striking.
The non-nappers showed no signs of improvement on the second test – even if they had reported thinking about the maze during their rest period. Similarly, the subjects who napped, but who did not report experiencing any maze-related dreams or thoughts during their sleep period, showed little, if any, improvement. But, the nappers who described dreaming about the task showed dramatic improvement, 10 times more than that shown by those nappers who reported having no maze-related dreams.
“These dreamers described various scenarios – seeing people at checkpoints in a maze, being lost in a bat cave, or even just hearing the background music from the computer game,” explains first author Erin Wamsley, PhD, a postdoctoral fellow at BIDMC and Harvard Medical School. These interpretations suggest that not only was sleep necessary to “consolidate” the information, but that the dreams were an outward reflection that the brain had been busy at work on this very task.
Of particular note, say the authors, the subjects who performed better were not more interested or motivated than the other subjects. But, they say, there was one distinct difference that was noted.
“The subjects who dreamed about the maze had done relatively poorly during training,” explains Wamsley. “Our findings suggest that if something is difficult for you, it’s more meaningful to you and the sleeping brain therefore focuses on that subject – it ‘knows’ you need to work on it to get better, and this seems to be where dreaming can be of most benefit.”
Furthermore, this memory processing was dependent on being in a sleeping state. Even when a waking subject “rehearsed and reviewed” the path of the maze in his mind, if he did not sleep, then he did not see any improvement, suggesting that there is something unique about the brain’s physiology during sleep that permits this memory processing.
“In fact,” says Stickgold, “this may be one of the main goals that led to the evolution of sleep. If you remain awake [following the test] you perform worse on the subsequent task. Your memory actually decays, no matter how much you might think about the maze.
“We’re not saying that when you learn something it is dreaming that causes you to remember it,” he adds. “Rather, it appears that when you have a new experience it sets in motion a series of parallel events that allow the brain to consolidate and process memories.”
Ultimately, say the authors, the sleeping brain seems to be accomplishing two separate functions: While the hippocampus is processing information that is readily understandable (i.e. navigating the maze), at the same time, the brain’s higher cortical areas are applying this information to an issue that is more complex and less concrete (i.e. how to navigate through a maze of job application forms).

“Our [nonconscious] brain works on the things that it deems are most important,” adds Wamsley. “Every day, we are gathering and encountering tremendous amounts of information and new experiences,” she adds. “It would seem that our dreams are asking the question, ‘How do I use this information to inform my life?’”

Families, Alcohol, Recovery & ‘The Limits Of Love’
I have re-posted this article from psych central as it is a thorough, well written and balanced view of the impact of alcoholism in families, the hope for recovery and the role of families and the community in helping those with substance over-use illnesses: Please read!Gredit: psychcentral.com
On April 25th, Hallmark Hall of Fame will broadcast the movie “When Love Is Not Enough — The Lois Wilson Story,” starring Winona Ryder and Barry Pepper (CBS, 9:00 pm ET). The movie, which portrays the life of Lois Wilson, co-founder of Al-Anon Family Groups and wife of Alcoholics Anonymous co-founder Bill Wilson, is based on William G. Borchert’s 2005 book, The Lois Wilson Story: When Love Is Not Enough.
Borchert’s earlier screenplay was the basis of the acclaimed movie My Name is Bill W. which starred James Woods, James Garner, and JoBeth Williams. The premiere of the movie also falls during the National Council on Alcoholism and Drug Dependence, Inc.’s (NCADD) 24th Annual Alcohol Awareness Month with its theme, “When Love Is Not Enough: Helping Families Coping With Alcoholism.”
Lois Wilson fell in love with a man whose alcoholism brought his life and their relationship to the brink before he began his personal recovery and helped found Alcoholics Anonymous. Lois and many of the other wives of early AA members also began to band together for mutual support, formalizing these meetings into Al-Anon Family Groups in 1951.
When Love is Not Enough is the story of Lois Wilson and her life with Bill Wilson. The reach of her and their stories is unfathomable and inseparable from the larger stories of AA and Al-Anon and the influence their lives would exert on the larger story of the professional treatment and recovery of individuals and families affected by addiction to alcohol and other drugs. As William Borchert suggests:
“In the end, Bill Wilson’s alcoholism proved not to be the tragic undoing of this brilliant and loving couple, but rather the beginning of two of the twentieth century’s most important social and spiritual movements- Alcoholics Anonymous and Al-Anon Family Groups.”
There are presently more than 114,500 Alcoholics Anonymous groups (with a combined membership of more than 2 million) and more than 25,000 Al-Anon/Alateen groups (with a combined membership estimated at more than 340,000) hosting local meetings worldwide.
When Love is Not Enough is clearly more than a love story, though it is surely that. Readers of Psych Central and the people they serve will discover in this movie six profound lessons about the impact of alcoholism and alcoholism recovery on intimate relationships and the family.
1. Prolonged cultural misunderstandings about the nature of alcoholism have left a legacy of family shame and secrecy. Centuries of debates between those advocating religious, moral, criminal, psychiatric, psychological, medical and sociological theories of alcoholism failed to offer clear guidance to individuals and families affected by alcoholism. When Love is Not Enough is in part a poignant history of the hidden desperation many families experienced before the birth of Alcoholics Anonymous, Al-Anon, and modern alcoholism treatment. Lois Wilson and Anne Bingham helped change that history in 1951 when they organized 87 groups of wives of AA members into the Al-Anon Family Groups.
2. Alcoholism is a family disease in the sense that it also wounds those closest to the alcohol dependent person; transforms family relationships, roles, rules, and rituals; and isolates the family from potential sources of extended family, social, and community support. And, it has far reaching, long-lasting effects on the physical and emotional health of the family and children. When Love is Not Enough conveys the physical and emotional distress of those struggling to understand a loved one who has lost control of drinking and its consequences.
It vividly portrays the disappointment, confusion, frustration, anger, resentment, jealousy, fear, guilt, shame, anxiety and depression family members experience in the face of alcoholism. The recognition that significant others and their children become as sick as the person addicted and are in need of a parallel pathway of recovery were the seeds from which Al-Anon and Alateen grew.
3. The family experience of alcoholism is often one of extreme duality. When Love is Not Enough poignantly conveys this duality: brief hope-inspiring interludes of abstinence or moderated drinking, periods of peacefulness, moments of love and shared dreams for the future — all relentlessly violated by explosive bouts of drinking and their devastating aftereffects. Memories of that lost person and those moments and dreams co-exist even in the face of the worst effects of alcoholism on the family.
It is only in recognizing this duality of experience and the character duality of the alcoholic that one can answer the enigmatic question that is so often posed about Lois Wilson’s contemporary counterparts, “Why does she/he stay with him/her?” As clinicians, we can too often forget that these family stories contain much more than the pathology of alcohol or drug dependence (White, 2006).
Click image to read reviews
4. Family recovery from alcoholism is a turbulent, threatening and life-changing experience. The hope of all families and children wounded by alcoholism is that the drinking will stop and with it, the arrival of an idyllic family life. Lois Wilson’s story confirms what research on family recovery from addiction is revealing: recovery from alcoholism can destabilize intimate and family relationships. Stephanie Brown and Virginia Lewis (1999), in their studies of the impact of alcoholism recovery on the family, speak of this as the “trauma of recovery.”
People recovering from alcoholism, their families, and their children can and often do achieve optimum levels of health and functioning, but this achievement is best measured in years rather than days, weeks, or months. That recognition in the life of Lois Wilson underscored the need for sustained support for families as they went through this process.
5. We cannot change another person, only ourselves. If there is a central, singular message from Lois Wilson’s life and from the Al-Anon Family Groups program, this may well be it. Al-Anon’s defining moments came when family members stopped focusing on how they could change and control their addicted family member and focused instead on their own need for regeneration and spiritual growth, the overall health of their families and the comfort and help they could offer each other and other families similarly affected.
Their further discovery that AA’s twelve step program of recovery could also guide the healing of family members marks the birth of the modern conceptualization of family recovery. The 2009 Al-Anon Membership Survey confirms the wide and enduring benefits members report experiencing as a result of their sustained involvement in Al-Anon—irrespective of the drinking status of their family members.
6. The wonder of family recovery. As a direct result of Lois’s groundbreaking work in co-founding Al-Anon and the impact it has had on the field of alcohol and drug treatment, family recovery from alcoholism is a reality for millions of Americans today, and the hope, help, and healing of family recovery has become the most powerful way to break the intergenerational cycle of alcoholism and addiction in the family.
The growing interest in the lives of Bill and Lois Wilson — as indicated by a stream of memoirs, biographies, plays, and films — is testimony to the contributions that Alcoholics Anonymous and Al-Anon Family Groups have made to personal and family recovery from alcoholism and to the ever-widening adaptation of the Twelve Steps to other problems of living (Wilson, 1994).
Psych Central readers will find much of value in “When Love Is Not Enough — The Lois Wilson Story,” including the power of Al-Anon as a tool of support for clients living with someone else’s alcoholism. A DVD of the movie and a Viewer’s Guide, for use as a tool in family and community education, will be available at www.hallmarkhalloffame.com on April 25th, the day of the movie’s premiere.

Violent Video Games & Kids: Definitive Study Shows Both Short & Long Term Harmful Effects
Iowa State University Distinguished Professor of Psychology Craig Anderson has made much of his life’s work studying how violent video game play affects youth behavior. And he says a new study he led, analyzing 130 research reports on more than 130,000 subjects worldwide, proves conclusively that exposure to violent video games makes more aggressive, less caring kids — regardless of their age, sex or culture.

“We can now say with utmost confidence that regardless of research method — that is experimental, correlational, or longitudinal — and regardless of the cultures tested in this study [East and West], you get the same effects,” said Anderson, who is also director of Iowa State’s Center for the Study of Violence. “And the effects are that exposure to violent video games increases the likelihood of aggressive behavior in both short-term and long-term contexts. Such exposure also increases aggressive thinking and aggressive affect, and decreases prosocial behavior.”
The study was conducted by a team of eight researchers, including ISU psychology graduate students Edward Swing and Muniba Saleem; and Brad Bushman, a former Iowa State psychology professor who now is on the faculty at the University of Michigan. Also on the team were the top video game researchers from Japan — Akiko Shibuya from Keio University and Nobuko Ihori from Ochanomizu University — and Hannah Rothstein, a noted scholar on meta-analytic review from the City University of New York.
Meta-analytic procedure used in research
The team used meta-analytic procedures — the statistical methods used to analyze and combine results from previous, related literature — to test the effects of violent video game play on the behaviors, thoughts and feelings of the individuals, ranging from elementary school-aged children to college undergraduates.
The research also included new longitudinal data which provided further confirmation that playing violent video games is a causal risk factor for long-term harmful outcomes.
“These are not huge effects — not on the order of joining a gang vs. not joining a gang,” said Anderson. “But these effects are also not trivial in size. It is one risk factor for future aggression and other sort of negative outcomes. And it’s a risk factor that’s easy for an individual parent to deal with — at least, easier than changing most other known risk factors for aggression and violence, such as poverty or one’s genetic structure.”
The analysis found that violent video game effects are significant in both Eastern and Western cultures, in males and females, and in all age groups. Although there are good theoretical reasons to expect the long-term harmful effects to be higher in younger, pre-teen youths, there was only weak evidence of such age effects.
Time to refocus the public policy debate
The researchers conclude that the study has important implications for public policy debates, including development and testing of potential intervention strategies designed to reduce the harmful effects of playing violent video games.
“From a public policy standpoint, it’s time to get off the question of, ‘Are there real and serious effects?’ That’s been answered and answered repeatedly,” Anderson said. “It’s now time to move on to a more constructive question like, ‘How do we make it easier for parents — within the limits of culture, society and law — to provide a healthier childhood for their kids?'”

But Anderson knows it will take time for the creation and implementation of effective new policies. And until then, there is plenty parents can do to protect their kids at home.
“Just like your child’s diet and the foods you have available for them to eat in the house, you should be able to control the content of the video games they have available to play in your home,” he said. “And you should be able to explain to them why certain kinds of games are not allowed in the house — conveying your own values. You should convey the message that one should always be looking for more constructive solutions to disagreements and conflict.”
Anderson says the new study may be his last meta-analysis on violent video games because of its definitive findings. Largely because of his extensive work on violent video game effects, Anderson was chosen as one of the three 2010 American Psychological Association Distinguished Scientist Lecturers

The Internet, Facebook, Pornography & Affairs: A Talkback Podcast Of Real-Life Stories
On Sunday 12th March I took part in an amazing talk-back discussion on Peter Jan
etzki’s “Talking Life” radio program on which I am a regular guest. The discussion, which involved a number of stories from listeners calling in, was about the darker side of the internet and social networking. A number of people spoke of the tragic circumstances of losing their relationships through affairs, in which Facebook and other social networking sites where involved.

Brain Training Or Just Brain Straining?: The Benefits Of Brain Exercise Software Are Unclear
You’ve probably heard it before: the brain is a muscle that can be strengthened. It’s an assumption that has spawned a multimillion-dollar computer game industry of electronic brain-teasers and memory games. But in the largest study of such brain games to date, a team of British researchers has found that healthy adults who undertake computer-based “brain-training” do not improve their mental fitness in any significant way.
Read The Original Research Paper (Draft POF)
The study, published online Tuesday by the journal Nature, tracked 11,430 participants through a six-week online study. The participants were divided into three groups: the first group undertook basic reasoning, planning and problem-solving activities (such as choosing the “odd one out” of a group of four objects); the second completed more complex exercises of memory, attention, math and visual-spatial processing, which were designed to mimic popular “brain-training” computer games and programs; and the control group was asked to use the Internet to research answers to trivia questions.
All participants were given a battery of unrelated “benchmark” cognitive-assessment tests before and after the six-week program. These tests, designed to measure overall mental fitness, were adapted from reasoning and memory tests that are commonly used to gauge brain function in patients with brain injury or dementia. All three study groups showed marginal — and identical — improvement on these benchmark exams.
But the improvement had nothing to do with the interim brain-training, says study co-author Jessica Grahn of the Cognition and Brain Sciences Unit in Cambridge. Grahn says the results confirm what she and other neuroscientists have long suspected: people who practice a certain mental task — for instance, remembering a series of numbers in sequence, a popular brain-teaser used by many video games — improve dramatically on that task, but the improvement does not carry over to cognitive function in general. (Indeed, all the study participants improved in the tasks they were given; even the control group got better at looking up answers to obscure questions.) The “practice makes perfect” phenomenon probably explains why the study participants improved on the benchmark exams, says Grahn — they had all had taken it once before. “People who practiced a certain test improved at that test, but improvement does not translate beyond anything other than that specific test,” she says.
The authors believe the study, which was run in conjuction with a BBC television program called “Bang Goes the Theory,” undermines the sometimes outlandish claims of many brain-boosting websites and digital games. According to a past TIME.com article by Anita Hamilton, HAPPYneuron, an example not cited by Grahn, is a $100 Web-based brain-training site that invites visitors to “give the gift of brain fitness” and claims its users saw “16%+ improvement” through exercises such as learning to associate a bird’s song with its species and shooting basketballs through virtual hoops. Hamilton also notes Nintendo’s best-selling Brain Age game, which promises to “give your brain the workout it needs” through exercises like solving math problems and playing rock, paper, scissors on the handheld DS. “The widely held belief that commercially available computerized brain-training programs improve general cognitive function in the wider population lacks empirical support,” the paper concludes.

Not all neuroscientists agree with that conclusion, however. In 2005, Torkel Klingberg, a professor of cognitive neuroscience at the Karolinska Institute in Sweden, used brain imaging to show that brain-training can alter the number of dopamine receptors in the brain — dopamine is a neurotransmitter involved in learning and other important cognitive functions. Other studies have suggested that brain-training can help improve cognitive function in elderly patients and those in the early stages of Alzheimer’s disease, but the literature is contradictory.
Klingberg has developed a brain-training program called Cogmed Working Memory Training, and owns shares in the company that distributes it. He tells TIME that the Nature study “draws a large conclusion from a single negative finding” and that it is “incorrect to generalize from one specific training study to cognitive training in general.” He also criticizes the design of the study and points to two factors that may have skewed the results.
On average the study volunteers completed 24 training sessions, each about 10 minutes long — for a total of three hours spent on different tasks over six weeks. “The amount of training was low,” says Klingberg. “Ours and others’ research suggests that 8 to 12 hours of training on one specific test is needed to get a [general improvement in cognition].”
Second, he notes that the participants were asked to complete their training by logging onto the BBC Lab UK website from home. “There was no quality control. Asking subjects to sit at home and do tests online, perhaps with the TV on or other distractions around, is likely to result in bad quality of the training and unreliable outcome measures. Noisy data often gives negative findings,” Klingberg says.
Brain-training research has received generous funding in recent years — and not just from computer game companies — as a result of the proven effect of neuroplasticity, the brain’s ability to remodel its nerve connections after experience. The stakes are high. If humans could control that process and bolster cognition, it could have a transformative effect on society, says Nick Bostrom of Oxford University‘s Future of Humanity Institute. “Even a small enhancement in human cognition could have a profound effect,” he says. “There are approximately 10 million scientists in the world. If you could improve their cognition by 1%, the gain would hardly be noticeable in a single individual. But it could be equivalent to instantly creating 100,000 new scientists.”
For now, there is no nifty computer game that will turn you into Einstein, Grahn says. But there are other proven ways to improve cognition, albeit only by small margins. Consistently getting a good night’s sleep, exercising vigorously, eating right and maintaining healthy social activity have all been shown to help maximize a brain’s potential over the long term.
What’s more, says Grahn, neuroscientists and psychologists have yet to even agree on what constitutes high mental aptitude. Some experts argue that physical skill, which stems from neural pathways, should be considered a form of intelligence — so, masterful ballet dancers and basketball players would be considered geniuses.
Jason Allaire, co-director of the Games through Gaming lab at North Carolina State University says the Nature study makes sense; rather than finding a silver bullet for brain enhancement, he says, “it’s really time for researchers to think about a broad or holistic approach that exercises or trains the mind in general in order to start to improve cognition more broadly.”
Or, as Grahn puts it, when it comes to mental fitness, “there are no shortcuts.”

“I Saw It Happen”: Children Who Witness Bullying Can Be Traumatized Too
Students who witness bullying of their peers may suffer more psychologically than the victim or the bullies.
Read The Original Research Paper (PDF)
2002 students ages 12 to 16 were surveyed at public schools in England. The survey asked them whether they’d committed, witnessed, or been the victim of several types of bullying behavior (e.g., kicking, name-calling, threatening, etc.) and whether they had experienced psychological stress symptoms such as anxiety, depression, or hostility.
Why bystanders suffer more than victims of bullying
As reported in the article, previous research shows that children who witness bullying feel guilty, presumably for not doing anything to help the victim.
In addition, they may have felt more stressed by vacillating between doing what they thought they should do (i.e., help the victim) on the one hand, and being afraid of being victimized themselves, on the other. Being in this type of “approach/avoidance” conflict has been shown in numerous studies to create high levels of stress.
The combination of guilt and fear among witnesses that they will experience the same thing may be another reason why they are more affected by bullying than the actual victims.

Uncertainty, especially combined with feelings of fear or guilt, contributes to stress. Stress leads to depression, anxiety, and other mental disorders.
Sitting down and discussing feelings of fear and guilt with your child may help to minimize the destructive force and ultimate impact of those emotions on mental health. Practical “survival” tips about how to avoid, distract, or other means of handling bullies would help, too, giving kids options if they are cornered by or are a witness to bullies in action.

Too Sexy Too Soon! PART ll – Are Sexual Images Now An Inescapable Part Of Children’s Lives?

THE professional body for Australia’s psychiatrists says the self-regulation of advertising and other media industries has failed to protect children from an onslaught of sexualised content.
Today’s generation of kids faced the “widespread use of sexual images to sell anything from margarine to fashion”, Professor Newman, the president of The Royal Australian and New Zealand College of Psychiatrists, said.
She said risque images were now an “inescapable” part of a child’s environment and pointed to billboard and TV advertising, magazines and music videos and even the posters in department stores.
Prof Newman is calling for a new regime of restrictions to protect children from both targeted and inadvertent exposure to sexualised media content.
She said more Australian research was needed to gauge its effect, though the anecdotal evidence was troubling.
The exposure appeared to push typically teenage and adult concerns about body image, “sexiness” and of being a “worthwhile individual” well into a child’s first years of life.

“I’ve seen four-year-olds and pre-schoolers who want to diet … going on intermittent food refusal,” she said.
Introducing sexualised themes to children could be overt, Prof Newman said, such as the move by a British retailer to sell a child’s pole dancing kit or “tween” magazines that offer advice to girls on how to be more attractive to the opposite sex.
But in many cases it was inadvertent.
“If you go into a 7-Eleven, at child’s eye-view will be Ralph magazine next to cartoons,” she said.
“The child might be attracted to the cartoons but what they are bombarded with are all these really quite unusual women with breast implants.
“It is sending a message that this is sexual attraction, this is what gets you on the front of a magazine.”
Prof Newman said it was natural for children to be inquisitive about bodies, and eventually about sex, though these matters should be discussed within a family at a developmentally appropriate time.
“They don’t need to know about adult sexual themes, and that’s the concern,” she said.
Prof Newman will speak on the issue at the Australian Conference on Children and the Media, in Sydney on Friday.
