Regina Nuzzo The gut may know better than the head whether a marriage will be smooth sailing or will hit the rocks after the honeymoon fades, according to research published today in Science1. Researchers have long known that new love can be blind, and that those in the midst of it can harbour positive illusions about their sweetheart and their future. Studies show that new couples rate their partner particularly generously, forgetting his or her bad qualities, and generally view their relationship as more likely to succeed than average2. But newlyweds are also under a lot of conscious pressure to be happy — or, at least, to think they are. Now a four-year study of 135 young couples has found that split-second, 'visceral' reactions about their partner are important, too. The results show that these automatic attitudes, which aren’t nearly as rosy as the more deliberate ones, can predict eventual changes in people’s marital happiness, perhaps even more so than the details that people consciously admit. The researchers, led by psychologist James McNulty of Florida State University in Tallahassee, tapped into these implicit attitudes by seeing how fast newlyweds could correctly classify positively and negatively themed words after being primed by a photo of their spouse for a fraction of a second. If seeing a blink-of-the-eye flash of a partner’s face conjures up immediate, positive gut-level associations, for example, the participant will be quicker to report that 'awesome' is a positive word and slower to report that 'awful' is a negative one. Researchers used the difference between these two reaction times as a measurement of a participant’s automatic reaction. © 2013 Nature Publishing Group

By Victoria Stern A trolley is hurtling down a track, and if nobody intervenes it will hit and kill five people. Psychologists use variations on this hypothetical situation to gauge people's gut reactions about morality. Here are three scenarios: The driver could switch the train to another track, on which one man stands. Should the driver reroute the trolley? Now suppose the trolley is driverless and you are a bystander. Should you hit a switch to divert the trolley so it hits the lone man? You are standing above the tracks on a bridge. You could stop the trolley and save the five people by pushing a large man to his death in front of the trolley. Would you push him? Most people say that the driver should reroute the train and that they would reroute the train with the switch but that they would not push the man to his death. This typical decision is associated with increased activity in the medial prefrontal cortex (green), which indicates a strong negative emotional reaction, as well as activity in the amygdala (red), which is involved in processing emotions and stressful events. © 2013 Scientific American

By Jesse Bering Disgust, in its most familiar form, is our response to something vile in the world—spoiled food, a dirty floor or rats cavorting in the subway. It is a contamination-avoidance mechanism that evolved to help us make biologically adaptive decisions in the heat of the moment. Yet disgust has also come to have powerful symbolic elements. When left unchecked, these symbolic qualities can have devastating impacts on our mental states. Consider, for example, the often dramatized, heartbreaking image of a woman crouched in the corner of a shower and frantically trying to scrub her body clean after being raped. Empirical evidence supports the characterization. Seventy percent of female victims of sexual assault report a strong impulse to wash afterward, and a quarter of these continue to wash excessively up to three months later. For women, simply imagining an unwanted advance can turn on this moral-cleansing effect. Psychiatrist Nichole Fairbrother of the University of British Columbia Hospital and her colleagues looked more closely at the phenomenon of mental pollution in a study published in 2005. Two groups of female participants were told to close their eyes and picture being kissed. The members of one group were instructed to imagine being aggressively cornered and kissed against their will. The members of the other group were asked to envision themselves in a consensual embrace. Only those women in the coercive condition chose to wash up after the study. In many cases, it seems as though a person's sense of self has become contaminated. © 2013 Scientific American

by Bruce Bower Thomas Jefferson defended the right to pursue happiness in the Declaration of Independence. But that’s so 237 years ago. Many modern societies champion everyone’s right to be happy pretty much all the time. Good luck with that, says psychologist Joseph Forgas of the University of New South Wales in Sydney. A lack of close friends, unfulfilled financial dreams and other harsh realities leave many people feeling lonely and forlorn a lot of the time. But there’s a mental and social upside to occasional downers that often goes unappreciated. “Bad moods are seen in our happiness-focused culture as representing a problem, but we need to be aware that temporary, mild negative feelings have important benefits,” Forgas says. Growing evidence suggests that gloomy moods improve key types of thinking and behavior, Forgas asserts in a new review paper aptly titled “Don’t worry, be sad!” For good evolutionary reasons, positive and negative moods subtly recruit thinking styles suited to either benign or troubling situations, he says. Each way of dealing with current circumstances generally works well, if imperfectly. New and recent studies described by Forgas in the June Current Directions in Psychological Science illustrate some of the ways in which periods of sadness spontaneously recruit a detail-oriented, analytical thinking style. Morose moods have evolved as early-warning signs of problematic or dangerous situations that demand close attention, these reports suggest. © Society for Science & the Public 2000 - 2013.

By Jason G. Goldman Scientists love yawning. No, that’s not quite right. Scientists love doing research on yawning. It seems to be of interest to folks in fields ranging from primatology to developmental psychology to psychopathology to animal behavior. If the notion of scientifically investigation the purpose of yawning makes you, well, yawn, then you’re missing one of the more interesting debates in the social cognition literature. To understand why yawning is about more than feeling tired or bored, we have to go back a few years. Once upon a time, scientists thought that yawning might be process through which the brain keeps itself cool (PDF). Yawning is associated with increases in blood pressure, and the consequential increase in blood flow might mean that the vascular system acts as a radiator, replacing the warm blood in the brain with cooler blood. It could also be that the deep inhalation of cold air during a yawn can, through convection, alter blood temperature which in turn could cool the brain. Even if it turns out that some yawns can be explained through purely physiological means, yawning is also contagious for humans and other species. If someone watches someone else yawning, they’ll be likely to yawn as well. That means that there is social component to yawning, and it might be related to empathy. It turns out that there’s a correlation between a person’s self-reported empathy and their susceptibility to reacting to a yawn contagion, and those who are more skilled at theory of mind tasks are also more likely (PDF) to yawn contagiously. © 2013 Scientific American

by Stephanie Pappas, LiveScience Apes orphaned by the African bushmeat trade lack the social savvy of apes raised by their mothers, a new study finds. The study links the emotional development of bonobos (Pan paniscus), one of humans' closest living relatives, with the ability to interact nicely with others, echoing how human emotions develop. Bonobos who are good at soothing themselves out of a bad mood are more likely to comfort other bonobos in distress, researchers report today (Oct. 14) in the journal Proceedings of the National Academy of Sciences. "By measuring the expression of distress and arousal in great apes, and how they cope, we were able to confirm that efficient emotion regulation is an essential part of empathy," study researcher Frans de Waal, of Emory University's National Primate Research Center, said in a statement. PHOTOS: How Santino, the Chimp, Attacks Visitors Though animal emotions "have long been scientifically taboo," de Waal said, he and his colleagues suspected that emotions might have evolved similarly before the bonobo and human lines split about 6 million years ago. The researchers observed juvenile bonobos at a sanctuary near Kinshasa in the Democratic Republic of the Congo. They watched as the young primates fought, threw tantrums and comforted one another by hugging or stroking. (See Video of a Bonobo Hug) In 373 post-distress interactions (318 caused by fights and 55 caused by tantrums), the researchers found that the better a bonobo was at soothing his or her own emotions, the more likely he or she was to rush to aid a friend in need. A similar pattern is seen in human interactions, the researchers reported. © 2013 Discovery Communications, LLC.

By Matthew D. Lieberman The popular conception of human nature emerging from psychology over the last century suggests that we are something of a hybrid, combining reptilian, instinct-driven motivational tendencies with superior higher-level analytic powers. Our motivational tendencies evolved from our reptilian brains eons ago and focus on the four Fs: fighting, fleeing, feeding, and fooling around. In contrast, our intellectual capacities are relatively recent advances. They are what makes us special. One of the things that distinguishes primates from other animals, and humans from other primates, is the size of our brains—in particular, the size of our prefrontal cortex, that is, the front part of the brain sitting right behind the eyes. Our big brains allow us to engage in all sorts of intelligent activities. But that doesn’t mean our brains evolved to do those particular things. Humans are the only animals that can learn to play chess, but no one would argue that the prefrontal cortex evolved specifically so that we could play the game of kings. Rather, the prefrontal cortex is often thought of as an all-purpose computer; we can load it up with almost any software (that is, teach it things). Thus, the prefrontal cortex seems to have evolved for solving novel hard problems, with chess being just one of an endless string of problems it can solve. From this perspective there might not be anything special at all about our ability and tendency to think about the social world. Other people can be thought of as a series of hard problems to be solved because they stand between us and our reptilian desires. Just as our prefrontal cortex can allow us to master the game of chess, the same reasoning suggests that our all-purpose prefrontal cortex can learn to master the social game of chess—that is, the moves that are permissible and advantageous in social life. From this perspective, intelligence is intelligence whether it’s being applied to social life, chess, or studying for a final exam. The creator of one of the most widely used intelligence tests espoused this view, arguing that social intelligence is just “general intelligence applied to social situations.” This view implies social intelligence isn’t special and our interest in the social world is just an accident—a consequence of the particular problems we are confronted with. © 2013 Salon Media Group, Inc

By R. Douglas Fields Human beings are utterly dependent on a complex social structure for their survival. Since all behavior is controlled by the brain, human beings may have evolved specialized neural circuits that are responsible for compliance with society’s rules. A new study has identified such a region in the human brain, and researchers can increase or decrease a person’s good behavior by electrodes on the scalp that stimulate or inhibit this brain circuit. Individuals must adhere to rules of society, which are ultimately enforced by punishments ranging from peer criticism to severe legal sanctions. “Our findings suggest a neural mechanism that is specialized for social norm compliance,” says Christian Ruff, one of the researchers in this new study published in the October 4, 2013 edition of the journal Science. In addition to illuminating the neurobiological basis for the evolution of social structure in humans, this new finding suggests new therapeutic treatments for people who have problems complying with normal social behavior. “That this mechanism can be upregulated by brain stimulation indeed suggests that targeted influences on these neural processes (by brain stimulation or pharmacology) may help to ameliorate problems with social norm compliance in medical and forensic contexts,” he says. It was already known from fMRI studies that neural activity increased in a specific part of the human cerebral cortex when participants comply with social norms. This region is located in the prefrontal region of the right cerebral hemisphere, called the right lateral prefrontal cortex (rLPFC). However, a correlation between brain activity and behavior does not prove that this neural circuit causes people to comply with social norms. Such proof would require manipulating electrical activity in this brain region to see if people altered their behavior in terms of complying with social expectations. © 2013 Scientific American

By PAM BELLUCK Say you are getting ready for a blind date or a job interview. What should you do? Besides shower and shave, of course, it turns out you should read — but not just anything. Something by Chekhov or Alice Munro will help you navigate new social territory better than a potboiler by Danielle Steel. That is the conclusion of a study published Thursday in the journal Science. It found that after reading literary fiction, as opposed to popular fiction or serious nonfiction, people performed better on tests measuring empathy, social perception and emotional intelligence — skills that come in especially handy when you are trying to read someone’s body language or gauge what they might be thinking. The researchers say the reason is that literary fiction often leaves more to the imagination, encouraging readers to make inferences about characters and be sensitive to emotional nuance and complexity. “This is why I love science,” Louise Erdrich, whose novel “The Round House” was used in one of the experiments, wrote in an e-mail. The researchers, she said, “found a way to prove true the intangible benefits of literary fiction.” “Thank God the research didn’t find that novels increased tooth decay or blocked up your arteries,” she added. The researchers, social psychologists at the New School for Social Research in New York City, recruited their subjects through that über-purveyor of reading material, Amazon.com. To find a broader pool of participants than the usual college students, they used Amazon’s Mechanical Turk service, where people sign up to earn money for completing small jobs.

If you look at the facts and figures on the mental health charity Mind's website, you'll find that around 1 in 4 people will experience some sort of mental health problem each year. About 10% of these people will see their doctor and be diagnosed as having a mental health problem, and of this group, a small proportion will in turn be referred to specialist psychiatric care. Of these people, precisely none resemble the breathtakingly ignorant costumes that have recently been withdrawn from Tesco and Asda. If you want to know what someone with a mental health issue looks like, just look around you. One of the most common types of mental health issue is anxiety – about 9% of people in Britain meet the criteria for mixed anxiety and depression, for example. We all feel anxious from time to time, and that's not necessarily a bad thing. Isaac Marks and Randy Nesse argued in 1994 that anxiety is an important emotion that has been shaped during the course of human evolution. If we are in a potentially dangerous environment, being anxious increases our awareness of our surroundings and puts us in a state of physiological readiness to deal with any threats. However, when an anxiety response kicks in too often, and in situations where it is not needed, it becomes a debilitating problem. In serious cases, anxiety can make it incredibly hard for the person to function. There's now a wealth of research that is trying to tap into the mechanisms involved in both sub-clinical and clinical forms of anxiety. By understanding what happens when we become anxious, we might be able to get a clearer idea of how and why things go wrong in anxiety disorders. For example, a new study published this week in the Journal of Neuroscience has suggested one potential contributing factor – how smells are processed. © 2013 Guardian News and Media Limited

Eliot Barford A parasite that infects up to one-third of people around the world may have the ability to permanently alter a specific brain function in mice, according to a study published in PLoS ONE today1. Toxoplasma gondii is known to remove rodents’ innate fear of cats. The new research shows that even months after infection, when parasites are no longer detectable, the effect remains. This raises the possibility that the microbe causes a permanent structural change in the brain. The microbe is a single-celled pathogen that infects most types of mammal and bird, causing a disease called toxoplasmosis. But its effects on rodents are unique; most flee cat odour, but infected ones are mildly attracted to it. This is thought to be an evolutionary adaptation to help the parasite complete its life cycle: Toxoplasma can sexually reproduce only in the cat gut, and for it to get there, the pathogen's rodent host must be eaten. In humans, studies have linked Toxoplasma infection with behavioural changes and schizophrenia. One work found an increased risk of traffic accidents in people infected with the parasite2; another found changes in responses to cat odour3. People with schizophrenia are more likely than the general population to have been infected with Toxoplasma, and medications used to treat schizophrenia may work in part by inhibiting the pathogen's replication. © 2013 Nature Publishing Group,

// by Jennifer Viegas Certain animals may weep out of sorrow, similar to human baby cries, say animal behavior experts. Many may have wondered if this was true after news reports last week described a newborn elephant calf at Shendiaoshan Wild Animal Nature Reserve in eastern China. The calf reportedly cried inconsolably for five hours after being stomped on by his mother that then rejected the little elephant. The calf, named Zhuang-zhuang, has since been "adopted" by a keeper and is doing well, according to the news site Metro. "Some mammals may cry due to loss of contact comfort," animal behaviorist Marc Bekoff explained to Discovery News. An ape's laugh is similar to a human one, according to new research exploring the evolution of laughter. "It could be a hard-wired response to not feeling touch," added Bekoff, former professor of ecology and evolutionary biology at the University of Colorado, Boulder. © 2013 Discovery Communications, LLC.

Bird species with larger than average brains have lower levels of a key stress hormone, an analysis of nearly 200 avian studies has concluded. Such birds keep their stress down by anticipating or learning to avoid problems more effectively than smaller-brained counterparts, researchers suggest. Birds in the wild lead a stressful life. Constantly spotting predators lurking in the trees or sensing dramatic changes in temperature is essential for survival, but can leave birds on the edge of a nervous breakdown. Reading these cues triggers changes in the birds’ metabolism, particularly increases in the stress hormone corticosterone. A sharp release of the hormone within 1 to 2 minutes after a cue triggers an emergency response and prepares birds to react quickly to the threat. However, regular exposure to the dangers of the wild and, hence, to high levels of this hormone, has serious health consequences and shortens life expectancy. Not all birds respond to stress in the same way, however, notes Daniel Sol an ornithologist at the Centre for Ecological Research and Forestry Applications in Cerdanyola del Vallès, Spain. He and colleagues have for years looked at the differences between big-brained birds, such as crows and parrots, and those with smaller brains, such as chickens and quails. The former survive better in nature and are also more successful at establishing a community in a new environment. In their new work, they connect brain size to handling stress. Sol; Ádám Lendvai, an evolutionary biologist at the College of Nyíregyháza in Hungary; and colleagues scoured the avian research literature to find studies that had measured corticosterone levels in birds in varying situations. © 2012 American Association for the Advancement of Science

By Michele Solis Loneliness is bad for our health, according to a robust body of research. And isolation is known to shorten lives—but experts were not sure if the real culprit was the pain and stress of loneliness, as opposed to a lack of social connectedness. Now psychologists have untangled the two factors and discovered that even superficial contact with other people may improve our health. Led by Andrew Steptoe of University College London, the study surveyed 6,500 people aged 52 or older about their social contacts and experiences of loneliness. After seven years, the researchers followed up to see who had died. Initially, people rated as highly lonely seemed to die at a higher rate than those with low or average scores. Yet this difference disappeared when taking into account a person's health. Greater social isolation, however, came with an increased incidence of death: 21.9 percent of people ranked as highly isolated died compared with 12.3 percent of less isolated people. After taking into account health and other demographic factors, this difference amounted to a 1.26-fold increase in mortality associated with high social isolation. The findings, published online on March 25 in the Proceedings of the National Academy of Sciences USA, suggest that even brief social contact that does not involve a close emotional bond—such as small talk with a neighbor or a bus driver—could extend a person's life. Although the results hint that city living or group homes may be beneficial, Steptoe says they do not negate the downside of loneliness. “There's ample evidence that loneliness relates to well-being and other health outcomes besides death,” he says. “But our study suggests a broader view of beneficial social relationships. They're not simply to do with close emotional relationships.” © 2013 Scientific American,

Piercarlo Valdesolo Public opinion towards science has made headlines over the past several years for a variety of reasons — mostly negative. High profile cases of academic dishonesty and disputes over funding have left many questioning the integrity and societal value of basic science, while accusations of politically motivated research fly from left and right. There is little doubt that science is value-laden. Allegiances to theories and ideologies can skew the kinds of hypotheses tested and the methods used to test them. These, however, are errors in the application of the method, not the method itself. In other words, it’s possible that public opinion towards science more generally might be relatively unaffected by the misdeeds and biases of individual scientists. In fact, given the undeniable benefits scientific progress yielded, associations with the process of scientific inquiry may be quite positive. Researchers at the University of California Santa Barbara set out to test this possibility. They hypothesized that there is a deep-seated perception of science as a moral pursuit — its emphasis on truth-seeking, impartiality and rationality privileges collective well-being above all else. Their new study, published in the journal PLOSOne, argues that the association between science and morality is so ingrained that merely thinking about it can trigger more moral behavior. The researchers conducted four separate studies to test this. The first sought to establish a simple correlation between the degree to which individuals believed in science and their likelihood of enforcing moral norms when presented with a hypothetical violation. Participants read a vignette of a date-rape and were asked to rate the “wrongness” of the offense before answering a questionnaire measuring their belief in science. Indeed, those reporting greater belief in science condemned the act more harshly. © 2013 Nature Publishing Group

By GRETCHEN REYNOLDS Our genes may have a more elevated moral sense than our minds do, according to a new study of the genetic effects of happiness. They can, it seems, reward us with healthy gene activity when we’re unselfish — and chastise us, at a microscopic level, when we put our own needs and desires first. To reach that slightly unsettling conclusion, researchers from the University of North Carolina and the University of California, Los Angeles, had 80 healthy volunteers complete an online questionnaire that asked why they felt satisfied with their lives. Then the researchers drew their blood and analyzed their white blood cells. Scientists have long surmised that moods affect health. But the underlying cellular mechanisms were murky until they began looking at gene-expression profiles inside white blood cells. Gene expression is the complex process by which genes direct the production of proteins. These proteins jump-start other processes, which in the case of white blood cells control much of the body’s immune response. It turned out that different forms of happiness were associated with quite different gene-expression profiles. Specifically, those volunteers whose happiness, according to their questionnaires, was primarily hedonic, to use the scientific term, or based on consuming things, had surprisingly unhealthy profiles, with relatively high levels of biological markers known to promote increased inflammation throughout the body. Such inflammation has been linked to the development of cancer, diabetes and cardiovascular disease. They also had relatively low levels of other markers that increase antibody production, to better fight off infections. Copyright 2013 The New York Times Company

Philip Ball He is sometimes called the first rock star. He would whip his long hair around as he played, beads of sweat flying into the audience, and women would swoon or throw their clothes on to the stage. This is not Mick Jagger or Jimmy Page, but Franz Liszt, the nineteenth-century Hungarian pianist whose theatrical recitals made the composer Robert Schumann say that “a great deal of poetry would be lost” had Liszt played behind a screen. But who cares about the histrionics — it’s the music that matters, right? Not according to the latest study, which shows that people’s judgements about the quality of a musical performance are influenced more by what they see than by what they hear. The findings, reported this week in the Proceedings of the National Academy of Sciences by social psychologist Chia-Jung Tsay of University College London1, may be embarrassing and even shocking to music lovers. The vast majority of participants in Tsay’s experiments — around 83% of both untrained participants and professional musicians — insisted at the outset that sound was their key criterion for assessing video and audio recordings of performances. Yet it wasn’t. The participants were presented with recordings of the three finalists in each of ten prestigious international competitions, and were asked to guess the winner. With just sound, or sound and video, novices and experts both guessed right at about the same level as chance (33% of the time), or a little less. But with silent video alone, the success rate for both was about 46–53%. The experts did no better than the novices. © 2013 Nature Publishing Group

By Bruce Bower NEW YORK CITY — Psychiatrists regularly get criticized for turning typical life problems into medical disorders. But in an odd reversal, many mental health clinicians are trying to transform one certified mental illness, borderline personality disorder, into a label for needy, manipulative people who don’t need treatment, a sociologist reported at the American Sociological Association’s annual meeting on August 11. Patients with borderline personality disorder, unlike people with schizophrenia or other serious mental conditions, are often viewed by mental health providers as having cynically planned out rash acts and even suicide attempts, sociologist Sandra Sulzer of the University of North Carolina at Chapel Hill found in extensive interviews with 22 psychiatrists and psychologists in the United States. The condition includes difficulty controlling emotions, intense but unstable relationships, recklessness, cutting and other acts of self-harm, along with attempted and completed suicides. Before Sulzer’s study, little was known about how mental health professionals discuss and deal with this troubling set of symptoms. “Clinicians frequently view borderline personality disorder symptoms as signs of badness, not sickness, and as a code to route patients out of mental health care,” Sulzer said. That finding goes a long way toward explaining why many borderline personality disorder patients receive no treatment despite the availability of effective forms of psychotherapy (SN: 6/16/07, p. 374), she suggested. © Society for Science & the Public 2000 - 2013

A stroke patient has developed a rare neurological condition nine months into his recovery that leaves him disgusted by words printed in a certain shade of blue and lifted to ecstasy by the sound of music by brass instruments, a Toronto neuroscientist says. The case, described in today's issue of the medical journal Neurology, involves an anonymous 45-year-old patient in Toronto who was initially frightened by the conflicting senses he began to experience. It is only the second known case of a patient developing the neurological condition after a brain injury. High-pitched brass instruments like those played in the theme from James Bond movies elicited feelings of ecstasy and created light blue flashes in his peripheral vision. They also caused large parts of his brain to light up in tests, the report says. "I heard it one day some time after the stroke and I went for a ride that was, it was cosmic in its voyage and it was wonderful," the patient said in a hospital YouTube interview. In contrast, when the euphonium was played in the study, the man said the response was cut off. Synesthesia is a neurological condition in which one sense, such as hearing, is simultaneously perceived by one or more additional senses, such as sight. The word synesthesia comes from two Greek words, syn (together) and aisthesis (perception); literally, "joined perception." People who report such experiences are known as synesthetes. © CBC 2013
