High-Testosterone People Feel Rewarded By Others' Anger

High-Testosterone People Feel Rewarded By Others' Anger, New Study Finds
ScienceDaily (May 12, 2007) — Most people don't appreciate an angry look, but a new University of Michigan psychology study found that some people find angry expressions so rewarding that they will readily learn ways to encourage them.


•"It's kind of striking that an angry facial expression is consciously valued as a very negative signal by almost everyone, yet at a non-conscious level can be like a tasty morsel that some people will vigorously work for," said Oliver Schultheiss, co-author of the study and a U-M associate professor of psychology.

The findings may explain why some people like to tease each other so much, he added. "Perhaps teasers are reinforced by that fleeting 'annoyed look' on someone else's face and therefore will continue to heckle that person to get that look again and again," he said. "As long as it does not stay there for long, it's not perceived as a threat, but as a reward."

The researchers took saliva samples from participants to measure testosterone, a hormone that has been associated with dominance motivation.

Participants then worked on a "learning task" in which one complex sequence of keypresses was followed by an angry face on the screen, another sequence was followed by a neutral face, and a third sequence was followed by no face.

Participants who were high in testosterone relative to other members of their sex learned the sequence that was followed by an angry face better than the other sequences, while participants low in testosterone did not show this learning advantage for sequences that were reinforced by an angry face.

Notably, this effect emerged more strongly in response to faces that were presented subliminally, that is, too fast to allow conscious identification. Perhaps just as noteworthy, participants were not aware of the patterns in the sequences of keypresses as they learned them.

While high-testosterone participants showed better learning in response to anger faces, they were unaware of the fact that they learned anything in the first place and unaware of what kind of faces had reinforced their learning.

Michelle Wirth, the lead author of the study and now a postdoctoral researcher at the University of Wisconsin, Madison, added: "Better learning of a task associated with anger faces indicates that the anger faces were rewarding, as in a rat that learns to press a lever in order to receive a tasty treat. In that sense, anger faces seemed to be rewarding for high-testosterone people, but aversive for low-testosterone people."
She said the findings contribute to a body of research suggesting that perceived emotional facial expressions are important signals to help guide human behavior, even if people are not aware that they do so.

"The human brain may have built-in mechanisms to detect and respond to emotions perceived in others," she said. "However, what an emotional facial expression, such as anger, 'means' to a given individual—whether it is something to pursue or avoid, for example—can vary."

U-M psychology researchers Michelle Wirth and Schultheiss, the authors of the study, published their findings in the journal Physiology and Behavior.

Do Angry Men Get More Attention? Anger And First Impressions

Do Angry Men Get Noticed?
Science Daily (June 7, 2006) — By comparing how quickly human facial expressions of different types are detected in a crowd of neutral faces, researchers have demonstrated that male angry faces are a priority for visual processing -- particularly for male observers. The findings are reported by Mark Williams of the Massachusetts Institute of Technology and Jason Mattingley of the University of Melbourne, Australia, and appear in the June 6th issue of Current Biology.

In evolutionary terms, it makes sense that our attention is attracted by threat in the environment. It has long been hypothesized that facial expressions that signal potential threat, such as anger, may capture attention and therefore "stand out" in a crowd. In fact, there are specific brain regions that are dedicated to processing threatening facial expressions. Given the many differences between males and females, with males being larger and more physically aggressive than females, one might also suspect differences in the way in which threat is detected from individuals of different genders.

In the new work, Williams and Mattingley show that angry male faces are found more rapidly than angry female faces by both men and women. In addition, men find angry faces of both genders faster than women, whereas women find socially relevant expressions (for example, happy or sad) more rapidly. The work suggests that although males are biased toward detecting threatening faces, and females are more attuned to socially relevant expressions, both sexes prioritize the detection of angry male faces; in short, angry men get noticed. The advantage for detecting angry male faces is consistent with the notion that human perceptual processes have been shaped by evolutionary pressures arising from the social environment.

If You Have Internet Access In Your Home You Are More Likely To Be In A Relationship

Internet Access at Home Increases the Likelihood That Adults Will Be in Relationships, Study Finds
Science Daily (Aug. 19, 2010) — Adults who have Internet access at home are much more likely to be in romantic relationships than adults without Internet access, according to research to be presented at the 105th Annual Meeting of the American Sociological Association.

"Although prior research on the social impacts of Internet use has been rather ambiguous about the social cost of time spent online, our research suggests that Internet access has an important role to play in helping Americans find mates," said Michael J. Rosenfeld, an associate professor of sociology at Stanford University and the lead author of the study, "Meeting Online: The Rise of the Internet as a Social Intermediary."

According to the study, 82.2 percent of participants who had Internet access at home also had a spouse or romantic partner, compared to a 62.8-percent partnership rate for adults who did not have Internet access. The paper uses data from Wave I of the How Couples Meet and Stay Together (HCMST) survey, a nationally representative survey of 4,002 adults, of whom 3,009 had a spouse or romantic partner.

In addition to finding that people are more likely to be in romantic relationships if they have Internet access in their homes, Rosenfeld and study co-author Reuben J. Thomas, an assistant professor of sociology at the City University of New York, found that the Internet is the one social arena that is unambiguously gaining importance over time as a place where couples meet.

"With the meteoric rise of the Internet as a way couples have met in the past few years, and the concomitant recent decline in the central role of friends, it is possible that in the next several years the Internet could eclipse friends as the most influential way Americans meet their romantic partners, displacing friends out of the top position for the first time since the early 1940s," Rosenfeld said.

The study also found that the Internet is especially important for finding potential partners in groups where the supply is small or difficult to identify such as in the gay, lesbian, and middle-aged heterosexual communities.

Among couples who met within two years of the HCMST Wave I survey in the winter of 2009, 61 percent of same-sex couples and 21.5 percent of heterosexual couples met online.

"Couples who meet online are much more likely to be same-sex couples, and somewhat more likely to be from different religious backgrounds," Rosenfeld said. "The Internet is not simply a new and more efficient way to keep in touch with our existing networks; rather the Internet is a new kind of social intermediary that may reshape the kinds of partners and relationships we have."

People Who Lie On Online Dating Services Likely Are People-Pleasers Who Want To Present Themselves In The Most Favorable Light To Get Someone To Like

Online Daters Behave Similarly to Those Who Meet Face-to-Face, Researcher Says
ScienceDaily (Mar. 8, 2010) — People who lie on online dating services likely are people-pleasers who want to present themselves in the most favorable light to get someone to like them -- just as they would in face-to-face dating, according to a University of Kansas researcher.

Jeffrey Hall, assistant professor of communication studies, surveyed more than 5,000 participants in a national Internet matchmaking service to determine what kinds of people are most likely to lie during the online dating process. He asked them how likely they were to lie about topics such as assets, relationship goals, personal interests, personal attributes, past relationships, age and weight.

"What people lie about depends on what kind of people they are," Hall said. "For example, if you're an extrovert, you might downplay the number of past relationships you've had because chances are you've had more relationships than an introvert."

Those most likely to lie during online dating experiences are "high self-monitors" -- people who have an acute sense of what people like and control their behavior to achieve social ends. Their actions are not necessarily manipulative, Hall said, but rather reflect a desire to be liked and to fit in.

Hall's research was published in the February issue of the Journal of Social and Personal Relationships.

In the study, men admitted to lying more overall, but women were most likely to lie about their weight. Because online daters hope to meet face-to-face eventually, the amount of lying is quite small, Hall said.

"Online daters shouldn't be concerned that most people are presenting a false impression of themselves," Hall said. "What influences face-to-face dating influences the online world

Communication In Hospitals. What happens When There Is Hand Off From One Shift To The Next?

Communication Often Fumbled During Patient Hand-Offs in Hospital Science Daily (Mar. 13, 2010) — As shifts change in a hospital, outgoing physicians must "hand off" important information to their replacements in a brief meeting. But a new study of this hand-off process finds that the most important information is not fully conveyed in a majority of cases, even as physicians rate their communication as successful. -------------------------------------------------------------------------------- See Also: Health & Medicine •Today's Healthcare •Smoking •Staying Healthy •Medical Imaging •Disability •Diseases and Conditions Reference •Pediatrics •Bone scan •List of medical topics •Palliative care The research, published by University of Chicago researchers in the March issue of Pediatrics, highlights the importance of educating doctors about successful communication skills during hand-offs. 

The results also emphasize the risk inherent in increased hand-offs necessitated by restrictions on medical resident work hours, even as further work limits are being discussed. "When resident hours are shortened, you have more hand-offs," said Vineet Arora, MD, assistant professor of medicine at the University of Chicago Medical Center. "You could have concerns about either a tired physician who knows the patient or a well-rested physician that may not know the patient. The trade-off is between fatigue and familiarity." Conducted through a unique collaboration between physicians and psychologists at the University of Chicago, the study observed hand-off communication between pediatric interns -- first-year residents -- at Comer Children's Hospital at the University of Chicago. Interns at the end of an overnight shift would spend a total of 10-15 minutes sharing information about hospitalized patients with the resident relieving them in a designated hand-off room.

 Both the outgoing and incoming interns were then asked by researchers about what they thought was the most important information conveyed during the hand-off about each patient. Surprisingly, what the outgoing intern identified as the most important information was not successfully communicated to the incoming intern 60 percent of the time. The rationale for certain medical decisions -- such as why a patient is on a particular drug or why the primary care physician should be contacted -- was also not understood by the receiving intern in a majority of cases. But despite these miscommunications, interns on both sides of the hand-off consistently rated the quality of their communication as very high. Boaz Keysar, Ph.D., a professor of psychology at the University of Chicago and co-author of the paper, said that this disconnect between perceived and actual success of communication is common in other settings. "You would imagine the kind of miscommunication we discover elsewhere actually might be reduced when the stakes are high in a clinical setting because it matters so much," Keysar said. "But the opposite is true, which I think is counter-intuitive and important to know." The results were even more striking given the optimal hand-off conditions for interns at Comer Children's Hospital. In each hand-off, a conversation takes place in a designated room under supervision by more experienced physicians. In previous research, Arora found that many hospitals and programs have much less organized hand-off procedures -- if they occur at all. In illustrating the communication breakdowns that plague even best-case hand-off conditions, Arora and Keysar hope to inform medical centers and schools of the need for better education about hand-offs. The study found that "anticipatory guidance" -- offering to-do items or if-then advice -- was a more effective way of communicating information between interns than passing on knowledge items in bulk. Currently, Arora and colleagues are working on a simulation exercise for fourth-year medical students to train more effective hand-off communication skills. 

 Such training, they hope, will be more effective than relying upon computer programs and electronic medical records to facilitate hand-off communication. A verbal exchange of information remains important so that young doctors can make quick, informed decisions about patients, Arora said. "IT solutions cannot substitute for a successful communication act," Arora said. "We aren't at the point where computers are going to do that for us. Technology solutions can help so that you have the information that you need when you need it, but to look at that information and be able to make a judgment about what to do, is what the hand-off conversation is for." But while researchers look for the best way to improve those conversations, Arora and Keysar hope that medical policymakers are aware of the risks inherent in the current hand-off model. As the Accreditation Council for General Medical Education ponders further restrictions upon the number of hours residents and interns can work, the consequences of those reduced hours must be acknowledged, they said. "We tend to be very myopic in the way we think about this problem," Keysar said. "Reducing hours is good, but there's a cost that is not obvious at all, and this study really spells that cost out. It's very difficult for us to gauge how well we are understood, and this should be taken into account in the trade-off between a number of work hours and fatigue."
