(Press-News.org) Getting kids to share their toys is a never-ending battle, and compelling them to do so never seems to help. New research suggests that allowing children to make a choice to sacrifice their own toys in order to share with someone else makes them share more in the future. The new findings are published in Psychological Science, a journal of the Association for Psychological Science.
These experiments, conducted by psychological scientists Nadia Chernyak and Tamar Kushnir of Cornell University, suggest that sharing when given a difficult choice leads children to see themselves in a new, more beneficent light. Perceiving themselves as people who like to share makes them more likely to act in a prosocial manner in the future.
Previous research has shown that this idea – as described by the over-justification effect — explains why rewarding children for sharing can backfire. Children come to perceive themselves as people who don't like to share since they had to be rewarded for doing so. Because they don't view themselves as "sharers" they are less likely to share in the future.
Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids' willingness to share.
"Making difficult choices allows children to infer something important about themselves: In making choices that aren't necessarily easy, children might be able to infer their own prosociality."
To test this, the researchers introduced 3-5 year-old children to Doggie, a puppet, who was feeling sad. Some of the children were given a difficult choice: Share a precious sticker with Doggie, or keep it for themselves. Other children were given an easy choice between sharing and putting the sticker away, while children in a third group were required by the researcher to to share.
Later on, all the children were introduced to Ellie, another sad puppet. They were given the option of how many stickers to share (up to three). The kids who earlier made the difficult choice to help Doggie shared more stickers with Ellie. The children who were initially confronted with an easy choice or who were required to give their sticker to Doggie, on the other hand, shared fewer stickers with Ellie.
"You might imagine that making difficult, costly choices is taxing for young children or even that once children share, they don't feel the need to do so again," Chernyak says. "But this wasn't the case: Once children made a difficult decision to give up something for someone else, they were more generous, not less, later on."
Another experiment supported these findings, illustrating that children are more generous after choosing to share valuable toy frogs compared to non-valuable ripped pieces of paper. Those who initially shared the frogs with Doggie shared more stickers with Ellie later on. Those who readily shared the paper, on the other hand, shared fewer stickers with Ellie. Therefore, children did not benefit from simply choosing to give something up, but rather from willingly choosing to give something up of value.
"Given the high amount of emphasis we place on choice during early childhood, especially in this culture, it is important to delineate specifically what choice might do — and not do — for young children," Chernyak says.
"Children are frequently taught to share, be polite, and be kind to others. In order to bring us closer to one day figuring out how to best teach children these skills, it is important to figure out which factors may aid in young children's sharing behavior," Chernyak concludes. "Allowing children to make difficult choices may influence their sharing behavior by teaching them greater lessons about their abilities, preferences, and intentions towards others."

Effects of Parkinson's-disease mutation reversed in cells
2013-08-17
UC San Francisco scientists working in the lab used a chemical found in an anti-wrinkle cream to prevent the death of nerve cells damaged by mutations that cause an inherited form of Parkinson’s disease. A similar approach might ward off cell death in the brains of people afflicted with Parkinson’s disease, the team suggested in a study reported online in the journal Cell on August 15.
The achievement marks a pharmacologic milestone as the first highly specific targeting of a member of an important class of enzymes called kinases to increase rather than to inhibit ...

Calcium plus vitamin D supplementation does not reduce joint symptoms in postmenopausal women
2013-08-16
Philadelphia, PA, August 15, 2013 – A team of investigators systematically analyzed the effect of calcium and vitamin D supplementation on joint symptoms in a rigorous and controlled study of postmenopausal women. They found that supplementation did not reduce the severity of joint symptoms reported by the participants. Their results are published in the Journal of the Academy of Nutrition and Dietetics.
The influence of low calcium and vitamin D deficiency on joint symptoms has been studied with mixed results. Only some observational studies have associated vitamin D ...
'Reprogrammed' treatment-resistant lymphomas respond to cancer drugs
2013-08-16
PHILADELPHIA — A phase I clinical trial showed diffuse, large B-cell lymphomas (DLBCLs) resistant to chemotherapy can be reprogrammed to respond to treatment using the drug azacitidine, according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research.
Patients whose lymphomas recur after initial chemotherapy are treated with a combination of approaches, including high-dose chemotherapy followed by a stem cell transplant. However, some patients have tumors that do not respond to these extensive second treatments, and many of ...
New flow battery could enable cheaper, more efficient energy storage
2013-08-16
CAMBRIDGE, MA -- MIT researchers have engineered a new rechargeable flow battery that doesn't rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.
The palm-sized prototype generates three times as much power per square centimeter as other membraneless systems -- a power density that is an order of magnitude higher than that of many lithium-ion batteries and other commercial and experimental energy-storage systems.
The device stores and releases energy in a device that relies on a ...
Middle-aged men, women not equal in heart attack risk
2013-08-16
High cholesterol levels are much more risky for middle-aged men than middle-aged women when it comes to having a first heart attack, a new study of more than 40,000 Norwegian men and women has shown.
The study, just published in the September issue of Epidemiology, shows that being a middle-aged male and having high cholesterol levels results in a negative synergistic effect that the researchers did not observe in women. However, current clinical guidelines for treating high cholesterol levels do not differentiate between men and women.
"Our results suggest that in ...
Chemotherapy before radiotherapy for testicular cancer could reduce long-term side-effects
2013-08-16
Giving men with testicular cancer a single dose of chemotherapy alongside radiotherapy could improve the effectiveness of treatment and reduce the risk of long-term side-effects, a new study reports.
As many as 96% of men with testicular cancer now survive at least ten years from diagnosis (1), but more advanced forms need to be treated with combination chemotherapy – which can have serious long-term complications.
Researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust have therefore been searching for new treatments that would ...

Agricultural fires in Mozambique and Malawi
2013-08-16
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected dozens of fires burning in southeastern Africa in mostly Mozambique and Malawi. The fires are outlined in red.
The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality. The main growing season starts with the first ...
