Gender plays a strong role in how people remember, a new Cornell study confirms. Research – and many tales from real life – report that women are typically better at remembering past events than men. Why?

“It appears that, compared with men, women may attend to and encode more information during ongoing events, experience similar rates of forgetting, and then show greater ability to access retained event information at recall,” said author Qi Wang, professor of human development in Cornell’s College of Human Ecology.

“Our findings also suggest that the content of memories is reconstructed over time in a gendered fashion,” Wang said. “The findings help us understand gender differences in memory and inform the theoretical debate about where in the memory formation process these differences emerge.”

Her study, “Gender and Emotion in Everyday Event Memory,” is published in the journal Memory (21:4).

Wang tackled the central question of whether women’s superior memory for personally experienced events is due to differences in how men and women initially encode event information in the brain, retain it over time or access it later during retrieval. It also examined how women’s memories become more socially oriented than men’s.

For the research, a culturally diverse group of 60 college undergraduates received three text messages over the course of a week that prompted them to immediately write down what had happened to them during the past 30 minutes. At the end of the week, they were asked to recall as much detail as possible about these events in a surprise memory test.

Compared with men, the women in the study recorded more event details initially and then recalled more details more accurately about the remembered events a week later, even after controlling for the additional detail women originally encoded. And while the men and women in the study recorded similar event content initially, at recall, the women reported their experiences by focusing more on relationships and social interactions than men.

“These findings are provocative in showing that women and men see their worlds differently, likely due to different cognitive styles, and that gendered ideologies come into play in memory reconstruction,” Wang added.

The research was supported in part by federal formula funds received from the Cooperative State Research, Education and Extension Service in the U.S. Department of Agriculture.

College-aged women judge promiscuous female peers – defined as bedding 20 sexual partners by their early 20s – more negatively than more chaste women and view them as unsuitable for friendship, finds a study by Cornell developmental psychologists.

Participants’ preference for less sexually active women as friends remained even when they personally reported liberal attitudes about casual sex or a high number of lifetime lovers.

Men’s views, on the other hand, are less uniform – favoring the sexually permissive potential friend, the non-permissive one or showing no preference for either when asked to rate them on 10 different friendship attributes. Promiscuous men favored less sexually experienced men, however, if they viewed other promiscuous men as potentially interested in stealing their girlfriends.

The findings suggest that women still face a double standard that shames “slutty” women and celebrates “studly” men, said lead author Zhana Vrangalova, a graduate student in the field of human development in the College of Human Ecology. The study, “Birds of a Feather? Not When It Comes to Sexual Permissiveness,” published online May 19 in the Journal of Social and Personal Relationships, reports that promiscuous women, therefore, are at greater risk for social isolation and poor psychological and physical health.

“Sexually permissive women are ostracized for being ‘easy,’ whereas men with a high number of sexual partners are viewed with a sense of accomplishment,” Vrangalova said. “What surprised us in this study is how unaccepting promiscuous women were of other promiscuous women when it came to friendships – these are the very people one would think they could turn to for support.”

She added that prior research shows that men often view promiscuous women as unsuitable for long-term romantic relationships, leaving these women outside of many social circles.

“The effect is that these women are really isolated,” Vrangalova said.

For the study, 751 college students provided information about their sexual experience and views on casual sex. They read a near-identical vignette about a male or female peer, the only difference being the character’s number of lifetime sexual partners (two or 20). When asked about the person on a range of friendship factors, female participants – regardless of their own promiscuity – viewed sexually permissive women more negatively on nine of 10 friendship attributes, judging them more favorably only on their outgoingness.

Permissive men only identified two measures, mate guarding and dislike of sexuality, where they favored less sexually active men as friends, showing no preference or favoring the more promiscuous men on the eight other variables. Even sexually modest men preferred the non-permissive potential friend in only half of all variables.

The authors posit that evolutionary concerns may be leading men and women to disapprove of their bed-hopping peers as friends. They may actually be seeking to guard their mates from a threat to their relationship, Vrangalova said.

In the case of promiscuous women rejecting other women with a high number of sexual partners, Vrangalova suggested that they may be seeking to distance themselves from any stigma that is attached to being friends with such women.

The authors report that the findings could aid parents, teachers, counselors, doctors and others who work with young people who may face social isolation due to their sexual activity.

The study is co-authored by Rachel E. Bukberg ’11 and Gerulf Rieger, postdoctoral associate in human development. It was funded in part by an award from the Human Ecology Alumni Association.

Preschoolers universally recognize that one’s choices are not always free – that our decisions may be constrained by social obligations to be nice to others or follow rules set by parents or elders, even when wanting to do otherwise.

As they age, however, American kids are more prone to acknowledge one’s freedom to act against such obligations compared to Nepalese children, who are less willing to say that people can and will violate social codes, finds a cross-cultural study by Cornell developmental psychologists titled “A Comparison of Nepalese and American Children’s Concepts of Free Will,” published May 20 in the journal Cognitive Science.

The findings, researchers said, suggest that culture is a significant influence on children’s concepts of choice regarding social norms.

“We know that adult views on whether social obligations constrain personal desires differ by culture, so this study helps us to determine when those variations emerge,” said first author Nadia Chernyak, a graduate student in the field of human development. “We can understand which ideas are universal and how culture influences individual ways of thinking.”

Led by Chernyak and Tamar Kushnir, the Evalyn Edwards Milman Assistant Professor in the College of Human Ecology, the research team interviewed children in the two countries to understand their beliefs on free choice and the physical, mental and social factors that limit choice.

Co-author Katie Sullivan ’11, a human development major with a minor in global health, aided the project while studying abroad in 2009 through the Cornell Nepal Study Program – a joint venture with Nepal’s Tribhuvan University. Sullivan took courses, learned the language and immersed herself in the culture before working with Chernyak and Kushnir to adapt their survey into a culturally appropriate version for Nepalese children. Partnering with Rabindra Parajuli, a Nepali research assistant, she worked with village and school leaders to arrange and conduct interviews with children.

Researchers read a series of nine vignettes to 45 Nepalese and 31 American children – hailing from urban and rural areas and ranging in age from 4 to 11 – about characters who wanted to defy various physical, mental and social constraints, asking kids whether the characters are free to follow their wishes and to predict if they will do so.

Nearly all children, across ages and cultures, said the characters could freely choose when no constraints were evident – opting for juice or milk at a meal or whether to draw with a pen or pencil, for example. The children also universally agreed that one is not free to choose to go beyond one’s physical and mental abilities – opting to float in the air or to surpass the limits of one’s knowledge and skill.

Developmental and cultural differences emerged, however, in children’s evaluation of choice in the face of social constraints. Younger children in both cultures said that various social and moral obligations limit both choice and action – that one cannot be mean to others, act selfishly or break rules and social conventions, for instance. But by age 10, American children tended to view these obligations as choices – free to be followed or disregarded based on personal desires. Nepalese children continued to believe that such constraints override individual preference.

“As children become more exposed to their own culture and adult behaviors, they are more likely to adopt their culture’s ways of thinking,” Chernyak said. Chernyak said also that future research could try to define what contributes to these differing views.

Qi Wang, professor of human development, is a co-author on the study, which was funded in part by the James S. McDonnell Foundation Causal Learning Collaborative Initiative. The work was also supported by a Cornell Cognitive Science Dissertation Fellowship awarded to Chernyak.
