'Financial infidelity'

What defines it, who is at risk, and what are the consequences?

Romantic partners aren’t always honest about money in their relationships, but when does hiding purchases, debt and savings constitute “financial infidelity”? Research by professors at four universities, including Indiana University, defines the concept and provides a means for predicting its occurrence within relationships.

Love, Lies and Money: Financial Infidelity in Romantic Relationships,” in the Journal of Consumer Research, is the first systematic investigation of financial infidelity in committed romantic relationships.

The professors define financial infidelity as “engaging in any financial behavior that is expected to be disapproved of by one’s romantic partner and intentionally failing to disclose this behavior to them.” It involves both the financial “act” and the subsequent concealment.

It differs from secret consumption and merely hiding spending because it involves a broader set of financial behaviors, including seemingly “positive” actions such as saving extra income in a personal bank account.

“Financial infidelity has the potential to be as harmful for relationship health and longevity as sexual infidelity, as conflicts over money are also a primary reason for divorce,” said co-author Jenny Olson, assistant professor of marketing at the IU Kelley School of Business. “Given the role that finances play in the health of relationships, consumers benefit from being aware of financial infidelity and its consequences.”

Growing in popularity is financial therapy, which combines finance with emotional support to help individuals and couples think, feel and behave with money to improve their overall well-being, make logical spending decisions and face financial challenges.

“An understanding of financial infidelity can benefit financial services companies and advisors, clinical therapists and relationship counselors, all of whom play a role in promoting consumer well-being,” Olson said. “If couples seek professional financial advice, they must be willing to openly discuss their spending and savings habits, debts and financial goals. It is clear that financial infidelity is a barrier to effective planning, as well as to a healthy relationship.”

The researchers developed a “financial infidelity scale (FI-Scale)” using a dozen lab and field tests. Key findings included:

  • Whether the financial act is expected to elicit any level of disapproval was more important than the degree of disapproval.
  • Consumers more prone to financial infidelity exhibited a stronger preference for secretive purchase options, such as using a personal credit card versus a jointly held card, and cash over credit.
  • A preference for ambiguous packaging and shopping at inconspicuous stores.
  • A greater likelihood of concealing financial information from their partner in a mobile banking app.

Each choice is relevant to marketers. The prevalence of financial infidelity among consumers and variations along the FI-Scale affect purchasing decisions. It is important that companies be aware of certain consumer segments that may be prone to financial infidelity and thus affect their bottom lines.

For example, the trend of businesses going “cash-free” may affect retailers such as beauty salons and gift shops because of the use of cash to disguise purchases. Consumers strategically using cash may be less willing to make purchases only for their pleasure or personal wants.

Minute Movements of Autistic Children and Their Parents Provide Clue to Severity of Disorder

Researchers measured minute movements as participants repetitively touched a spot on a touch screen.

Imperceptible variations in movement patterns among individuals with autism spectrum disorder are important indicators of the severity of the disorder in children and adults, according to a report presented at the 2014 Society for Neuroscience annual meeting in November.

For the first time, researchers at Indiana University and Rutgers University report developing a quantitative way to assess these otherwise ignored variations in movement and link those variations to a diagnosis.

“This is the first time we have been able to explicitly characterize subtypes of severity in autism spectrum disorder,” said Jorge V. José, Ph.D., vice president of research at Indiana University and the James H. Rudy Professor of Physics in the IU Bloomington College of Arts and Sciences. “We also have determined that a pattern exists in the movement variations in some cases between children with autism and their parents, leading us to surmise that genetics plays a role in movement patterns.”

Positional trajectories show the variations in speed and random movement of (from top) low functioning, non-verbal ASD, age 22; high functioning, verbal ASD, age 25; and adult control, age 22.

In a blinded study, José, who also is a professor of cellular and integrative physiology at the IU School of Medicine, and co-principal investigator Elizabeth B. Torres, Ph.D., an assistant professor in the Department of Psychology in the School of Arts and Sciences at Rutgers University, attached high-sensitivity movement sensors to the arms of study participants to track their micro-movements as they extended and retracted their hand to touch a specific spot on a touch screen.

Using analytics they developed, Drs. José and Torres, together with Di Wu, a Ph.D. graduate student in José’s lab in the physics department at IU Bloomington, evaluated the local spikes in speed — traditionally considered as noise in the data. The sensors recorded 240 movements per second for the 30 people with autism, eight healthy adults and 21 parents of children with autism tested. The participants were asked to touch a spot on a screen moving continuously about 100 consecutive times.

“These variations in the hand’s movement speed produced a pattern that clustered in specific regions of a graph that produced metrics we could use — not only in children with autism but in their parents,” Dr. Torres said. “People with autism are known to have problems with sensing their body motions and sensing their body in general. Our earlier research proved that the random patterns of their speed were significant. What we did not expect was to find random, minute speed fluctuations during the intentional action itself, much less identify this form of intentional tremor in some of their parents.”

That finding was part of the report presented by Wu at the 2014 Society for Neuroscience meeting in November attended by more than 32,000 scientists.

“In healthy adults, the minute fluctuations in the speed of their movements, which we call peripheral spikes or p-spikes, normally occur at the onset or at the end of the arm extension exercise,” Wu said. “They show very few p-spikes during the actual action, as the hand speeds up or slows down en route to the target. However, healthy children in the 3-to-5-year-old range have random patterns of p-spikes, as do adults and children with autism spectrum disorder.”

What this suggests, the researchers said, is that p-spikes normally become more organized with age in typically developing individuals. But, in children and adults with autism, the p-spikes remained random. The researchers tested people with autism between the ages of 3 and 30 and identified an absence of transition that typically developing children undergo after 4 or 5 years of age.

The researchers also tested 14 mothers and seven fathers who have a child with autism. When evaluating the noise from the data produced from the parents, the researchers were surprised to find that some of the parents had random p-spikes clustering in the graph similar to that of their children.

“This finding suggests that genetics may play a role in p-spike patterns,” Wu said. “We will need to further explore this result in other populations with neurodevelopmental disorders of known genetic origins and their family to better understand the surprising findings.”

Drs. José and Torres said the p-spike patterns are useful in determining severity of the disorder.

“Normally, children get more coordinated as they age, but we found that the young children with autism and the adults with autism all produced random p-spikes showing that they do not transition as they develop,” Dr. José said. “We also found a correlation between the randomness of the p-spikes and the severity of the autism disorder. Among those with autism, the more random their p-spikes, the lower spoken language ability they had overall.”

This research was funded by National Science Foundation Cyber-Enabled Discovery and Innovation Type I (Idea), grant number 0941587 — “A novel quantitative framework to study lack of social interactions in Autism Spectrum Disorders” — and by the New Jersey Governor’s Council for Medical Research and Treatment of Autism, grant number CAUT14APL018 — “New objective autism inventory to quantify peripheral plasticity during standard ADOS-2 social exchange.”

Bravest woman that ever lived

Erica Armstrong Dunbar enlists students’ help to tell untold stories of the “bravest woman that ever lived”

In an iconic image, Harriet Tubman stands calmly wrapped in a shawl. But the picture that most people associate with Tubman doesn’t scratch the surface of the strength and determination it took leading 60 to 70 slaves to safety through the Underground Railroad.

Advertisements

With the release of the film Harriet, Rutgers scholar Erica Armstrong Dunbar said it’s a good time to shed light on Tubman’s life not only as the famed Underground Railroad conductor, but as a sister, a daughter, a wife, a mother and a woman.

“What we know about Tubman’s life from history books really only consists of 10 years of her life, and I wanted to present her in a way that is fresh,’ said Dunbar, a Rutgers University–New Brunswick Charles and Mary Beard Professor of History and the author of She Came to Slay: The Life and Times of Harriet Tubman. “The point was to be accessible and have it be modern and contemporary, so it connects to readers across generations to make a story that is over 100 years old feel relevant today.”

Dunbar began with Tubman’s grandmother, a woman named Modesty, who endured the Middle Passage and arrived in colonial Maryland in the late eighteenth century. Tubman’s parents, Harriet “Rit” Green and Ben Ross were enslaved by different families on Maryland’s Eastern Shore. Tubman was born with the name Araminta Ross, and her family was separated as many others were during the slave trade, with her three sisters sold to different plantation owners.

“I wanted to start at the very beginning and talk about the things we don’t often hear,” Dunbar said. “I explore her teenage years and her marriage to John Tubman, who actually left her for another woman once she escaped to Philadelphia. I discuss her adopted child Gertie through her second marriage to Nelson Davis, a man 20 years her junior. A decade later, Tubman led a military expedition during the Civil War and rescued close to 750 enslaved people. After the war ended, she continued to fight for 53 years as an activist for the elderly and women’s rights. It’s important that we see all these different sides, so we can begin to look at her as a whole person.”

To offer this perspective, Dunbar enlisted research associates from various universities, including Rutgers–New Brunswick’s Ashley Council, a second-year graduate student focused on African-American history. Council spent months digging through the Freedmen’s Bureau Archives, 19th century newspapers, census data, civil war letters, black abolitionist papers, speeches and many other historical sources. She faced the complex task of uncovering slave history, much of it told through the lens of white supremacy.

“I researched portions of Tubman’s history like the Combahee River Raid, and I started constructing narratives that challenged me to write in a more accessible way, to touch on the humanity of the reader,” said Council, who plans to become a professor of African-American history. “There is not a lot of archival material about Tubman and the history of the enslaved . Archives weren’t made to make the enslaved visible. So, I had to take history based in white supremacy and find the narratives that were hidden beneath. It isn’t something our discipline always allows and this was an amazing opportunity to be a part of a new way of telling her story.”

Dunbar was invited to attend pre-screenings of the film Harriet, which she invited her graduate student associates to join. Students also discussed Tubman’s life in conjunction with the film release during live podcasts and Twitter chats. While there are some differences between her book and the film, there were moments that shed light on the militant side of Tubman, which Dunbar was happy to see on screen. 

“She was a fierce black woman — and certainly one of the bravest women that ever lived,” Dunbar said. “She made 13 trips along the Underground Railroad, traveling more than 100 miles and never lost one single person. She reminds us of the importance of the strength of leadership in the darkest of times and to stand up for social injustice. Her story offers hope and encouragement in battling the issues happening today.”

Dunbar said it was important to involve students in her research. 

“I want students to have the opportunity to work in the archives and uncover the fragments of history that are untold. It helps them see possibilities in the field of history and the prominence of the Department of History at Rutgers. We are the number one program in African American history in the nation for a reason.”

Unattainable Standards of Beauty for Today's Woman

Victoria Secret models shrink while average US women’s dress size increases

While the average American woman’s waist circumference and dress size has increased over the past 20 years, Victoria’s Secret fashion models have become more slender, with a decrease in bust, waist, hips and dress size, though their waist to hip ratio (WHR) has remained constant.

These findings represent an ideal of beauty that continuously moves further away from the characteristics of the average American woman.

Quantifying female body attractiveness is complex. Perceived attractiveness is influenced by physical and nonphysical traits and is further guided by media exposure and sociocultural standards of the time. One of the more established parameters to evaluate female body attractiveness is the WHR, which measures body fat distribution. Interestingly, WHR has continued to be an ideal beauty trait that has stayed constant over time and cross-culterally.

In order to evaluate trends of physical body attributes, researchers from Boston University School of Medicine (BUSM) measured and compared Victoria’s Secret models from 1995 to 2018. The first Victoria’s Secret runway show debuted 23 years ago and since then has been viewed by millions annually, making it the most watched fashion show worldwide.

The data showed that over time, Victoria’s Secret fashion models have become thinner, with smaller busts, waist, hips and dress size, whereas their WHR remained constant. “Conversely, the average American woman’s waist circumference and dress size has increased and varies between a misses size 16 and 18,” explained corresponding author Neelam Vashi, MD, assistant professor of dermatology at BUSM.

Advertisements

According to the researchers, in parallel with this trend, the percentage of women seeking cosmetic surgical procedures has dramatically increased and may be due to the desire to achieve the ideal WHR, which is a narrow waist set against fuller hips. Buttock and lower body lift has increased by 4,295 percent and 256 percent, respectively since 2000.

“Our results represent a potentially changing weight ideal of beauty that is moving farther away from the characteristics of the average American woman; however, a constant idealized WHR remains intact,” added Vashi, who also is director of the Boston University Cosmetic and Laser Center at Boston Medical Center.

The Surprising History of Christmas Traditions

Wassail, one of the oldest holiday drinks, is named after the Anglo-Saxon phrase “waes hael” or “good health.” Wassail was originally made with mulled ale, curdled cream, roasted apples, eggs, cloves, ginger, nutmeg and sugar

New Brunswick, N.J. (Dec. 19, 2019) – Did you know yuletide caroling began 1,000 years before Christmas existed? Or how about the fact that mistletoe was used to represent immortality long before the holiday reached Europe? And before there was eggnog, the medieval English drank wassail made from mulled ale. 

Advertisements

Maria Kennedy, an instructor of folklore at Rutgers University–New Brunswick’s Department of American Studies in the School of Arts and Sciences, has researched the European holiday traditions that predate – and became an inseparable part of – Christmas.

She shared her insights with Rutgers Today.

What is the origin of Christmas caroling?

The act of going from house to house during the darkest time of the year to spread hope through song has its origins​ throughout Europe and takes many forms including the British tradition of Wassail and Mumming, and the Slavic tradition of Koliada, which began before 998 B.C. In many traditions, people would go door to door and ask for permission to perform. They would recite poetry, sing and sometimes perform a skit. The idea was that these acts would bring about good fortune to influence a future harvest. Many of these visiting rituals were incorporated in the celebration of Christmas and are still performed in modern Ukraine as well as throughout Europe and across the United States.

Why do we associate Christmas with eggnog?

Holiday beverages like eggnog, mulled wine and hot cider often include cinnamon, cloves and/or other spices. In medieval England, these spices were of high value and would have been traded for other goods. They were a sign of wealth, so bringing them out for celebration was equivalent to bringing out the best wine for guests. Drinks with eggs and cream may seem strange to palates today, but these were also common in Medieval England. 

The ancestor of these drinks is wassail, named after the Anglo-Saxon phrase “waes hael” or “good health.” Wassail was originally made with mulled ale, curdled cream, roasted apples, eggs, cloves, ginger, nutmeg and sugar. It was served in huge bowls made of wood, pewter, porcelain, and silver. The act of wassailing would begin on the 12th day of Christmas – Jan. 5 or Jan. 6 – and included bonfires in the orchards, shooting guns to scare away bad spirits, caroling and pouring hot cider into the roots of trees for a good harvest the following year.

Advertisements

Where did mistletoe and evergreen trees become part of the holiday?  

Mistletoe, an evergreen shrub, was used in celebrations dating back to the ancient Druids – Celtic religious leaders – some 2,000 years ago. Mistletoe represented immortality because it continued to grow in the darkest time of the year and bore white berries when everything else had died. Hanging its sprigs over doorways and windows was supposed to keep the evil spirits of disease from entering a house. Farmers found it easiest to remove parasitic mistletoe from apple trees in winter when the branches were barren.

The decorating of evergreen trees is a German custom that began in the 16th century and was popularized in England and America during the reign of Queen Victoria after she married Prince Albert in 1840. Albert would decorate the trees at Windsor Castle with wax candles and sweets. By the 1860s, hundreds of Christmas trees were sold in Covent Garden and eventually the trend made its way into American tradition. Originally, trees would be decorated with oranges stuck with cloves, cinnamon sticks and pine cones. Sometimes, the nut would be removed from a walnut shell and replaced by a small gift or candy before being hung on a tree. 

Art Museum Offers New Tools for Visitors with Sensory-Related Disorders

Items inside sensory inclusive bags from KultureCity

Museum staff are trained to help visitors have a rewarding experience

New Brunswick, N.J. (Dec. 16, 2019) – The Zimmerli Art Museum at Rutgers University-New Brunswick is the first art museum in New Jersey to offer specialized tools to help visitors in the autism spectrum enjoy their visit without stressful sensory overload.

Advertisements

The museum is collaborating with KultureCity, a nonprofit that has also worked with MetLife Stadium, to offer the training and materials needed to provide a more positive experience for those with autism, PTSD or other conditions that may cause sensory overload.

Free sensory inclusive bags include fidget tools (handheld objects that can be squeezed and manipulated to help focus the user’s sense of touch), cue cards that people with verbal impairments can use to communicate their needs and moods, noise-cancelling headphones and weighted lap pads to help direct the user’s feeling of their center of gravity.

“A common misperception is that autism is just a behavioral disorder, but it affects processes in our nervous system, which can create a feeling of vertigo or the sense of a lack of gravity,” said Elizabeth Torres, a Rutgers professor of psychology and director of The New Jersey Autism Center of Excellence at Rutgers–New Brunswick. “Astronauts who return from a long space mission are given weighted suits to bring back their center of gravity until they readjust. In a similar fashion, people with autism can’t always feel their own body weight. For some, the feeling is constant and very disorienting.”

Through the partnership with Kulture City, Zimmerli staff received training on how to recognize when a visitor may have sensory needs, such as covering their ears or flapping their hands, and how to step in and offer them sensory support.

“We’re now better prepared to assist guests with autism and other sensory sensitivities in having the most comfortable and accommodating experience possible when attending any exhibition or program at the museum,” said Thomas Sokolowski, Zimmerli Art Museum Director.

Before adopting the new sensory tools, the Zimmerli offered customized group tours to visitors with autism and related conditions.  A KultureCity app is also available for download that displays available sensory devices at Zimmerli and how they can be accessed, as well as a customized social story, that helps visitors prepare for their visit

 “People with sensory disorders and their families now have the freedom to visit at any time and have confidence they will be assisted properly if they experience sensory overload or otherwise need support,” said Amanda Potter, curator of education at the Zimmerli.

Potter said the sensory tools can help people of all ages. “There is also a necklace that visitors can wear that alerts staff to keep a close eye on a person so they don’t get separated from their group, which can happen not only to children but to people with dementia.”

While the sensory tools are a big first step to helping combat sensory sensitivity, Torres said museums can do more, such as partnering with autism centers and offering information cards to improve public understanding of autism-related disorders.

“We are having exploratory conversations with Rutgers’ Center for Adult Autism Services to find more ways to help the autism community in New Jersey, including by providing job services and creating designated quiet spaces during crowded events, such as Rutgers Day,” Potter said. “Autism services are an area for growth, so we will work to expand our services. This is just the start.”

Rutgers-New Brunswick, is a leader in autism research and services, recently appointing its inaugural director of the Rutgers Center for Autism Research, Education and Services (RUCARES) and CHS-RUCARES, a clinical entity created through Rutgers’ partnership with Children’s Specialized Hospital. The university’s Douglass Developmental Disabilities Center includes an on-campus K-12 day school for children with autism. In addition, the university broke ground on a new state-of-the-art facility for the Rutger Center for Adult Autism Services, which provides employment, vocational training and other services and partners with Children’s Specialized Hospital to operate the New Jersey Autism Center of Excellence.

Combating Human Trafficking

Each year, more than 40 million men, women and children are trafficked worldwide. It manifests in numerous forms and has grown into a multi-billion-dollar illegal enterprise that is difficult to detect, prosecute and examine. Risk analysis is a critical tool for combating human trafficking and is central to informing global policy recommendations and assisting with targeted local and organizational efforts. Several studies will be presented during the Addressing Human Trafficking Risk symposium at the 2019 SRA Annual Meeting at the Crystal Gateway Marriott in Arlington, Virginia.

Many non-governmental organizations (NGOs) work to reduce human trafficking but often fail to understand the context and environment before taking action, resulting in ineffective and sometimes detrimental policies. JD Caddell, U.S. Military Academy, studied how girls were lured and trafficked by reframing the situation as a supply chain and looking at both supply and demand.

Caddell’s study, “Using system dynamics to set strategic priorities to address human trafficking,” revealed that NGO’s actions aimed solely at removing girls from the system yields few long-term benefits and creates more victims in the long run while raid and rescue operations only yields short-term gains.

Advertisements

“Many organizations use raid and rescue models because they provide “results,” in terms of girls saved, which provides validation and a mechanism for future NGO fundraising,” states Caddell. “However, our study showed that focusing on the demand side of the problem is more likely to generate large scale and sustainable progress.”

Because human trafficking is hidden, illegal and dangerous, it is difficult to gather the data needed to develop effective quantitative models and their response to interventions. Kayse Lee Maass, Ph.D., Northeastern University, has been working with survivors, law enforcement personnel and social scientists to better understand the structure and operations of trafficking networks, how they adapt and the dependencies between their cyber and social networks.

Maass’s study, “Modeling operations of human trafficking networks for effective interdiction,” provides non-profits, service providers, policy makers and other anti-trafficking stakeholders with decision support tools to effectively allocate resources to disrupt networks and ensure survivors have access to support services.

Advertisements

Similarly, Julia Coxen, University of Michigan, has approached the problem by decomposing the risks of human trafficking into the risks to public health, to security and to the community. Coxen’s study, “Risk analysis as a critical tool for human trafficking,” helps decision-makers better understand the complexities of human trafficking. The study also highlights the need for more evidence-based and quantitative risk analysis research to combat this global issue that impacts all levels of society.

Black Teens Face Racial Discrimination Multiple Times Daily

Teens in study experience anti-black microaggressions most frequently online, according to Rutgers researcher

Black teenagers experience daily racial discrimination, most frequently online, which can lead to negative mental health effects, according to a Rutgers researcher.

The study, published in the Journal of Applied Developmental Psychology, examined how often black teens experience racial discrimination each day – either personally or vicariously and online or offline.

The researchers surveyed 101 black youth between ages 13 and 17 from predominantly black neighborhoods in Washington, D.C., each day for two weeks about their experiences with racial discrimination and measured changes in their depressive symptoms across that period. The teens reported more than 5,600 experiences of racial discrimination in total – an average of more than five experiences per day.

Advertisements

“This research reflects what researchers and activists have asserted for years: Black adolescents are forced to face antiblack microaggressions on a daily basis. Importantly, this study expands the research on the many ways that discrimination happens, whether it is being teased by peers, asked to speak for their racial group in class or seeing a racist post on social media,” said lead author Devin English, an assistant professor at Rutgers School of Public Health.

Advertisements

The experiences reported in the study, which ranged from teasing about physical appearance to overt discrimination, mainly occurred online and led to short-term increases in depressive symptoms. Examples of discrimination included teasing by peers about wearing their hair natural, seeing jokes about their race online and witnessing a family member or friend being treated poorly due to their race or ethnicity.

“Racial teasing is important because it is one of the most common ways adolescents communicate about race,” English noted. “Critically, young people and adults, such as teachers, often see this teasing as harmless and choose not to address it. Our results, however, show several types of racial teasing are harmful for black adolescents.”

Advertisements

“Although public discourse can indirectly or directly blame health inequities on black youth, our study provides evidence that racial discrimination in society is a fundamental cause of these health inequities,” he continued. “Knowing this, people in positions of power such as clinicians, school administrators and policy makers have a responsibility to consider discrimination as a critical aspect of the daily experience and health of black teens. Racial discrimination prevention should be a public health imperative.”

Children of abused mothers

50% more likely to have low IQ

Children of women who reported domestic violence in pregnancy or during the first six years of the child’s life are almost 50% more likely to have a low IQ at age 8, research finds.

In the study by University of Manchester epidemiologists, 13% of children whose mothers did not experience domestic violence had an IQ of below 90 at 8 years of age.

If their mothers experienced physical violence from their partner either in pregnancy or during the first six years of the child’s life, the figure rises to 22.8%.

Advertisements

The team led by Dr Kathryn Abel from The University of Manchester show the chance of a low IQ rises to 34.6% if the mother was repeatedly exposed to domestic violence.

That means children with mothers who repeatedly suffer domestic violence during pregnancy and the first six years of their child’s life are almost three times more likely to have a low IQ at 8 years of age, find researchers.

Low IQ is defined as an IQ score less than 90, where a normal IQ is considered to be 100.

Advertisements

The study examined the link between domestic violence – also called Intimate partner violence (IPV) – and child intelligence at 8 year’s old, using 3,997 mother child pairs from The University of Bristol’s Avon Longitudinal Study of Parents and Children.

The study, funded by the Wellcome Trust and Medical Research Council, is published in Wellcome Open Research.

ALSPAC follows children from pregnancy, and measures emotional and physical domestic violence – also known as intimate partner violence – from pregnancy until eight years of age.

Advertisements

The intelligence of the children was measured at eight years using the Weschler standardised IQ test.

Dr Abel said: “We already know that 1 in 4 women age 16 and over in England and Wales will experience domestic violence in their lifetime and that their children are at greater risk of physical, social and behavioural problems.

“We also know that intelligence in childhood is strongly linked with doing well in adulthood, though there has been little evidence about the risk of low IQ for these children.

“While we cannot conclude that IPV causes low IQ, these findings demonstrate domestic violence has a measurable link, by mid-childhood, independent of other risk factors for low IQ.”

17.6% of the mothers in the study reported emotional violence and 6.8% reported physical violence.

The findings are independent of other risk factors for low IQ such as alcohol and tobacco use in pregnancy, maternal depression, low maternal education and financial hardship around the child’s birth.

There is some disagreement on whether the IQ test is a complete measure of intelligence, as it only considers verbal and non-verbal intelligence

Advertisements

However, it is regarded as useful by many experts because a high IQ has been demonstrated in many countries and cultures to associate with a broad range of improved social and health outcomes.

Dr Hein Heuvelman, from The University of Bristol added: “Exposure to domestic violence is common for children in the UK and an important and often overlooked risk factor in their life chances.

Advertisements

“So knowing the extent to which these already vulnerable children are further affected is a powerful argument for more, better and earlier intervention.

“Current support for women experiencing domestic violence is inadequate in some areas and absent in others.

“Early intervention with these families protects children from harm, but it may also prioritise their future development.”

How humans make choices in groups and social media?

A method with roots in AI uncovers how humans make choices in groups and social media

The choices we make in large group settings — such as in online forums and social media — might seem fairly automatic to us. But our decision-making process is more complicated than we know. So, researchers have been working to understand what’s behind that seemingly intuitive process.

Now, new University of Washington research has discovered that in large groups of essentially anonymous members, people make choices based on a model of the “mind of the group” and an evolving simulation of how a choice will affect that theorized mind.

Advertisements

Using a mathematical framework with roots in artificial intelligence and robotics, UW researchers were able to uncover the process for how a person makes choices in groups. And, they also found they were able to predict a person’s choice more often than more traditional descriptive methods. The results were published Wednesday, Nov. 27, in Science Advances.

“Our results are particularly interesting in light of the increasing role of social media in dictating how humans behave as members of particular groups,” said senior author Rajesh Rao, the CJ and Elizabeth Hwang professor in the UW’s Paul G. Allen School of Computer Science & Engineering and co-director of the Center for Neurotechnology.

“In online forums and social media groups, the combined actions of anonymous group members can influence your next action, and conversely, your own action can change the future behavior of the entire group,” Rao said.  

Advertisements

The researchers wanted to find out what mechanisms are at play in settings like these.

In the paper, they explain that human behavior relies on predictions of future states of the environment — a best guess at what might happen — and the degree of uncertainty about that environment increases “drastically” in social settings. To predict what might happen when another human is involved, a person makes a model of the other’s mind, called a theory of mind, and then uses that model to simulate how one’s own actions will affect that other “mind.”

While this act functions well for one-on-one interactions, the ability to model individual minds in a large group is much harder. The new research suggests that humans create an average model of a “mind” representative of the group even when the identities of the others are not known.

To investigate the complexities that arise in group decision-making, the researchers focused on the “volunteer’s dilemma task,” wherein a few individuals endure some costs to benefit the whole group. Examples of the task include guarding duty, blood donation and stepping forward to stop an act of violence in a public place, they explain in the paper.

To mimic this situation and study both behavioral and brain responses, the researchers put subjects in an MRI, one by one, and had them play a game. In the game, called a public goods game, the subject’s contribution to a communal pot of money influences others and determines what everyone in the group gets back. A subject can decide to contribute a dollar or decide to “free-ride” — that is, not contribute to get the reward in the hopes that others will contribute to the pot.

If the total contributions exceed a predetermined amount, everyone gets two dollars back. The subjects played dozens of rounds with others they never met. Unbeknownst to the subject, the others were actually simulated by a computer mimicking previous human players.

“We can almost get a glimpse into a human mind and analyze its underlying computational mechanism for making collective decisions,” said lead author Koosha Khalvati, a doctoral student in the Allen School. “When interacting with a large number of people, we found that humans try to predict future group interactions based on a model of an average group member’s intention. Importantly, they also know that their own actions can influence the group. For example, they are aware that even though they are anonymous to others, their selfish behavior would decrease collaboration in the group in future interactions and possibly bring undesired outcomes.”

In their study, the researchers were able to assign mathematical variables to these actions and create their own computer models for predicting what decisions the person might make during play. They found that their model predicts human behavior significantly better than reinforcement learning models — that is, when a player learns to contribute based on how the previous round did or didn’t pay out regardless of other players — and more traditional descriptive approaches.

Given that the model provides a quantitative explanation for human behavior, Rao wondered if it may be useful when building machines that interact with humans.

“In scenarios where a machine or software is interacting with large groups of people, our results may hold some lessons for AI,” he said. “A machine that simulates the ‘mind of a group’ and simulates how its actions affect the group may lead to a more human-friendly AI whose behavior is better aligned with the values of humans.”
