Gay youth today describe themselves as proud, happy, and grateful – something many of us would have found surprising a generation ago. Yet many adults seem skeptical about this change in perceptions and attitudes. What does it mean to be gay today? Professor Ritch Savin-Williams, professor emeritus of developmental psychology in the Cornell College of Human Ecology, observes that huge gaps still remain in our knowledge about gay youth’s basic developmental needs, their sexual and romantic life, and overall well-being. With his new book, Becoming Who I Am: Young Men on Being Gay, Savin-Williams aims to begin filling this void, exploring identity and sexuality as told by today’s generation of gay young men. Through a series of in-depth interviews with teenagers and men in their early 20s, he offers a contemporary perspective on gay lives in present day America. In a Chats in the Stacks book talk at Mann Library in March 2017, Dr. Savin-Williams shared highlights from this work and some thoughts about what his findings suggest for the future of gay youth in an age of growing tolerance.

Researchers in the social sciences have been searching for a holy grail: an accurate way to predict who is likely to engage in problematic behavior, like using drugs. Over the years experts in economics, psychology and public health have designed hundreds of questionnaires in an attempt to understand who will binge drink or have unprotected sex – and why.

Ph.D. ’15, of Vassar College, have just taken a sizable step toward answering those questions.

In a new study, Reyna and Wilhelms have debuted a new questionnaire that significantly outperforms 14 other gold-standard measures frequently used in economics and psychology. The measure’s 12 simple questions ask in various ways whether one agrees with the principle “sacrifice now, enjoy later.” Their study, “Gist of Delay of Gratification: Understanding and Predicting Problem Behaviors,” appeared Aug. 10 in the Journal of Behavioral Decision Making.

“People who get drunk frequently, party with drugs, borrow money needlessly or have unprotected sex disagreed more with the concept ‘sacrifice now, enjoy later’ than people who didn’t do these things,” Reyna said. “Instead, they leaned more toward ‘have fun today and don’t worry about tomorrow.’”

Having fun is generally good, she said. “But not being able to delay gratification can interfere with education, health and financial well-being, and the impact is greater for young people,” she added.

The questionnaire is based on Reyna’s fuzzy-trace theory. It says people boil down their personal values into a simple, qualitative “gist” of an idea – such as “sacrifice now, enjoy later.” When they have to make a life decision, they retrieve that gist and apply it to their situation.

In contrast, prevailing theory, with many questionnaires based on it, says that people make specific, quantitative trade-offs known as “delay discounting.” For example, those measures ask questions like, “Would you like $10 now or $11.50 in a week?”

“People do size up the trade-off, but they don’t make their decisions on that analysis,” Reyna said. “They think, ‘sacrifice now, benefit later.’ And therefore they study for the exam rather than go out to the party. It’s not about the party per se. It’s about the life principle.”

The researchers conducted four studies to get their results, comparing the measure, the Delay-of-Gratification Gist Scale, against 14 others. The Gist Scale’s questions include, “I wait to buy what I want until I have enough money,” “I think it is better to save money for the future” and “I am worried about the amount of money I owe.” Money is used as a “stand-in” or proxy for tempting rewards.

The first study asked 211 college students to take the Gist Scale and other measures that predict poor financial outcomes. The second and third studies, with 845 and 393 college students, respectively, compared the new measure against others involving delay discounting. With 47 teens and adult participants, the fourth study compared the Gist Scale against a widely used measure of impulsivity.

The Gist Scale is not only more accurate, it’s also shorter and simpler – some other measures are more than twice as long. It is also gender and age neutral, meaning it can be taken by anyone.

Reyna points out that cultures all over the world have aphorisms that encourage the ability to delay gratification. That skill can improve with practice, she said.

“Sometimes we send young people very mixed messages about struggle. I think it’s extremely important for them to know that struggle and pain are part of life and to be expected,” she said. “Staying the course, keeping your eyes on the prize – these values make a difference. And they can be taught and they can be practiced.”

Front and side views of two regions of interest for the origins of Alzheimer's disease - the basal forebrain, top, and the entorhinal cortex, bottom.

Alzheimer’s disease is a neurodegenerative disorder for which, despite years of research, there are no effective treatments or cures. However, recent breakthroughs in molecular genetics have shown that the disease may spread, like an infection, across closely connected areas of the brain. These findings underscore the need for research aimed at tracking its spread to the earliest points of origin in the brain, so therapies that target those areas can be developed.

An international collaboration between Nathan Spreng, Cornell assistant professor of human development and the Rebecca Q. and James C. Morgan Sesquicentennial Faculty Fellow in the College of Human Ecology, and Taylor Schmitz of the University of Cambridge’s Cognitive Brain Sciences Unit, sheds light on the basal forebrain region, where the degeneration of neural tissue caused by Alzheimer’s disease appears even before cognitive and behavioral symptoms of the disease emerge.

Their paper, “Basal forebrain degeneration precedes and predicts the cortical spread of Alzheimer’s pathology,” is published Nov. 4 in Nature Communications. Data used for their work were obtained from the Alzheimer’s Disease Neuroimaging Initiative database.

The basal forebrain contains very large and densely connected neurons that are particularly vulnerable to the disease. Schmitz and Spreng show that, as Alzheimer’s progresses, degeneration of the basal forebrain predicts subsequent degeneration in temporal lobe areas of the brain involved in memory. This pattern is consistent with other research showing that Alzheimer’s indeed spreads across brain regions over time, but the study challenges a widely held belief that the disease originates in the temporal lobe.

“We’re hoping that this work pushes a bit of a reorganization of the field itself, to reappraise where the disease originates,” Spreng said. “That could open up new avenues for intervention; certainly it would for detection.”

Their report is the product of a two-year study of a large sample of age-matched older adults. Within this sample, one group was cognitively normal, according to standard tests, while others were characterized by different levels of cognitive impairment:

  • Individuals with mild cognitive impairment (MCI) who did not progress to Alzheimer’s disease;
  • MCI individuals who progressed to Alzheimer’s after one year; and
  • Individuals classified as having Alzheimer’s throughout the duration of the study.

Through analysis of high-resolution anatomical magnetic resonance imaging of brain volumes, taken three times over the two-year study period, the researchers were able to determine that individuals with MCI or Alzheimer’s showed greater losses in gray matter volume in both the basal forebrain and temporal lobe, compared with cognitively normal controls. Intriguingly, they showed that over the two-year period, degeneration of neural tissue in the basal forebrain predicted subsequent tissue degeneration in the temporal lobe, but not the other way around.

A sampling of spinal fluid from healthy adults can detect an abnormal level of beta amyloid, indicative of Alzheimer’s, Spreng said. Test results showed that temporal lobes looked the same regardless of amyloid level, but the basal forebrain showed notable degeneration among those seemingly healthy adults with abnormal amyloid levels.

Spreng admits that being able to predict who will get the disease doesn’t mean a lot without a protocol to treat and, ultimately, cure the disease. “And it might induce more anxiety,” he said. But the more knowledge that can be gained now, he said, the better.

“Future molecular genetics work holds strong promise for developing therapeutic strategies to prevent the spread of pathology at stages of Alzheimer’s preceding cognitive decline,” Schmitz said. “Our clarification of an earlier point of Alzheimer’s propagation is therefore of utmost importance for guiding endeavors to combat this devastating disease.”

This work was funded by grants from the National Institutes of Health and the Alzheimer’s Association.

Marcel Proust’s madeleine cakes have nothing on Instagram and Twitter. But if they did, Proust’s memories could have been even more elaborate and vivid.

A new study – the first to look at social media’s effect on memory – suggests posting personal experiences on social media makes those events much easier to recall.

Qi Wang, Professor in Human Development

Qi Wang, Professor in Human Development

“If people want to remember personal experiences, the best way is to put them online,” said Qi Wang, the lead author of the study and professor of human development in the College of Human Ecology. “Social media – blogs, Facebook, Twitter, and others alike – provide an important outlet for us to recall memories, in the public space, and share with other people.”

Memory researchers have long known that when people write about personal experiences, reflect on them or talk about them with others, they tend to remember those events much better. “The process of writing about one’s experiences in the public sphere, often sustained by subsequent social feedback, may allow people to reflect on the experiences and their personal relevance,” the study said.

The act of posting on social media also plays a role in the construction of the self, said Wang, an expert in personal memory.

“We create a sense of self in the process of recalling, evaluating and sharing with others memories of personal experiences in our lives,” Wang said. “That’s happening when we use social media, without us even noticing it. We just think, ‘Oh, I’m sharing my experience with my friends.’ But by shaping the way we remember our experiences, it’s also shaping who we are.”

That’s especially facilitated by the interactive functions on many social media sites. For example, Facebook periodically shows users photos and posts from previous years to remind them of those events, prompting users to revisit those experiences.

“Memory is often selective. But in this case, the selection is not done by our own mind; it’s done by an outside resource,” Wang said. “So interactive functions on social networking sites can also shape how we view our experiences, how we view ourselves.”

Wang and her co-authors, Dasom Lee ’13, and Yubo Hou of Peking University, asked 66 Cornell undergraduates to keep a daily diary for a week. The study participants briefly described the events that happened to them each day, excluding daily routines such as “had breakfast.” For each event, they recorded whether they had posted the event on social media. And they rated the event’s personal importance and emotional intensity on five-point scales. At the end of the week and a week later, the students took surprise quizzes on how many events they could recall.

The researchers found that the online status of each event significantly predicted the likelihood of it being recalled at the end of both the first and second weeks. This was true even when they controlled for the personal importance and emotional intensity of the events. In other words, events posted online were more likely than those not posted online to be remembered over time, regardless of the characteristics of the events.

The research sheds new light on memory theories and have important implications for the construction of “the autobiographical self” in the digital age, the authors said. “This work is the first step toward a better understanding of the autobiographical self in the internet era where the virtual externalization of personal memories has become commonplace,” the study said.

The research, “Externalizing the autobiographical self: sharing personal memories online facilitated memory retention,” appeared Aug. 17 in the journal Memory.

A large and growing body of research shows that poor kids grow up to have a host of physical problems as adults.

Now add psychological deficits to the list, Cornell researchers say.

Childhood poverty can cause significant psychological deficits in adulthood, according to a sweeping new study. The research, conducted by tracking participants over a 15-year period, is the first to show this damage occurs over time and in a broad range of ways.

Impoverished children in the study had more psychological distress as adults, including more antisocial conduct like aggression and bullying and more helplessness behavior, than kids from middle-income backgrounds. Poor kids also had more chronic physiological stress and more deficits in short-term spatial memory.

Gary Evans, Elizabeth Lee Vincent Professor of Human Development

“What this means is, if you’re born poor, you’re on a trajectory to have more of these kinds of psychological problems,” said Gary Evans, the author of the study and the Elizabeth Lee Vincent Professor of Human Ecology, and professor in the departments of design and environmental analysis, and human development.

Why? In a word, stress.

“With poverty, you’re exposed to lots of stress. Everybody has stress, but low-income families, low-income children, have a lot more of it,” Evans said. “And the parents are also under a lot of stress. So for kids, there is a cumulative risk exposure.”

Evans, a child psychologist who specializes in the effects of stress on children, is the author of “Childhood poverty and adult psychological well-being,” published Dec. 12 in the Proceedings of the National Academic of Sciences (PNAS).

The findings are important because kids who grow up in poverty are likely to stay impoverished as adults, Evans said. For example, there’s a 40 percent chance that a son’s income will be the same as his father’s income. That’s because the United States has the least social mobility of any wealthy Western democracy, he said.

“People walk around with this idea in their head that if you work hard, play by the rules, you can get ahead,” Evans said. “And that’s just a myth. It’s just not true.”

In his study, Evans tested 341 participants, all white, at ages 9, 13, 17 and 24.

Short-term spatial memory was tested by asking adult study participants to repeat increasingly complex sequences of lights and sounds by pressing four colored pads in the correct order – similar to the “Simon” game. The adults who grew up in poverty had a diminished ability to recall the sequences, compared to those who did not.

“This is an important result because the ability to retain information in short-term memory is fundamental to a host of basic cognitive skills, including language and achievement,” Evans wrote.

Although the participants were assessed on this measure only when they were adults, this test had the strongest association with childhood poverty of the four measures.

Helplessnesswas assessed by asking the participants to solve an impossible puzzle. Adults who grew up in poverty gave up 8 percent quicker than those who weren’t poor as kids. Previous research has shown chronic exposure to uncontrollable stressors – such as family turmoil and substandard housing – tends to induce helplessness.

Mental healthwas measured with a well-validated, standardized index of mental health with statements including “I argue a lot” and “I am too impatient.” Adults who grew up in poverty were more likely to agree with those questions than adults from a middle-income background.

Chronic physiological stress was tested by measuring the participants’ blood pressure, stress hormones and body mass index. Adults who grew up in poverty had a higher level of chronic physical stress throughout childhood and into adulthood.

The study has two implications, Evans said. First, early intervention to prevent these problems is more efficient and more likely to work.

“If you don’t intervene early, it’s going to be really difficult and is going to cost a lot to intervene later,” he said.

Second, increasing poor families’ incomes is the most efficient way to reduce a child’s exposure to poverty and, in turn, their risk of developing psychological problems. Evans supports the creation of a safety net, similar to Social Security’s supplemental income for the elderly and disabled. If a family is poor and has children, the federal government should provide them with supplementary income sufficient to participate in society, he said.

“It’s not true you can’t do anything about poverty. It’s just whether there’s the political will, and are people willing to reframe the problem, instead of blaming the person who is poor and – even more preposterous – blaming their children,” he said.

“This is a societal issue, and if we decide to reallocate resources like we did with the elderly and Social Security, we could change the kind of data this study is showing,” he said.

“Could we get rid of poverty? Probably not,” Evans said. “But I think we could change it dramatically.”

The research was supported by the W.T. Grant Foundation, the John D. and Catherine T. MacArthur Foundation and the National Institute for Minority Health and Health Disparities.

Camille Sims '15 says fate brought her to Cornell. And now it has propelled her to reign as Miss New York and to finish second runner-up in September's Miss America competition.

As a teen growing up in Atlanta, Georgia, and Chattanooga, Tennessee, Sims volunteered with her mother in soup kitchens, joining the fight against hunger and homelessness. One day, while checking out books in an Atlanta public library, a Cornell recruiter approached her and encouraged her to attend an information session for the College of Human Ecology. There she discovered "how the college represents improving the human condition, solving social problems, and using research as a means to create social justice and to help people live better," she says.

"After that, I said, 'Mom, this is it, this is my school! I have to be there!'" Sims recalls.

As a freshman and a Meinig Family Cornell National Scholar, Sims sought out Anthony Burrow, assistant professor of human development, whose research on youth purpose and identity she had been tracking since high school. She took "every class that he offered" and conducted research and an independent study through his Purpose and Identity Processes Laboratory. Her project explored how mass incarceration impairs adolescent transitions into adulthood and sparked her to work with Ultimate Re-entry Opportunity of Tompkins County, which supports former inmates.

Today, she continues her work on reintegration and other social justice issues as a coordinator with Cornell Cooperative Extension and the Multicultural Resource Center.

"I wouldn't be doing the work that I am doing now had it not been for the conversations and experiences in Professor Burrow's classes and lab," Sims says.

"Because of her innovative scholarship and passion to contribute to the health of the communities in which she lives, Camille makes a formidable ally to those enduring imprisonment and who will eventually re-enter the community," Burrow says. "Her particular talents are noticeable and effective -- she's the kind of student who demands there always be greater meaning to the assignments in which she engages."

Crowned Miss New York in May, Sims is using her title to raise awareness for her platform, Ensuring Wellness and Fostering Food Justice. Sims was drawn to the cause from her early experiences fighting hunger, as well as her work as a Cornell undergraduate at Ithaca's Southside Community Center, where she has helped low-income families with eating healthfully on a budget. Sims credits Cornell's Public Service Center for matching her with local groups as a freshman and her Human Ecology education with making her more effective as an advocate.

"I took classes in nutrition and health, human development and nearly enough for a minor in policy analysis and management," Sims says. "I've been able to develop an understanding of the food system from all these perspectives and tie that into my Miss America platform."

A jazz singer and songwriter who plans to release her second album this fall, Sims hopes to use her winnings from the Miss New York and Miss America competitions to pay for graduate school, where she plans to continue her research in human development. Ultimately, she hopes to inspire others to engage with their communities and fight for social justice.

"Caring is crucial to moving anything forward," says Sims. "For us to move forward as a society, we must ask questions about the food system and start conversations about inequity. There can't be apathy about inequality and social justice if you want to thrive as a community."

-- Ted Boscia is director of communications and media for the College of Human Ecology.
