Review finds that men still have better spatial ability than women -- this may be explained by individual differences in gender-role identification

2013-04-04
(Press-News.org) The observation that males appear to be superior to females in some fields of academic study has prompted a wealth of research hoping to shed light on whether this is attributable to nature or nurture. Although there is no difference in general intelligence between the sexes, studies over the past 35 years have consistently found that overall men do much better in tests of spatial ability than women. This difference may have something to do with why there are still fewer women in tertiary education studying science, technology, engineering and math – all subjects where it helps to have good spatial ability.

More in-depth assessment, however, reveals that this might be an over-simplification of the facts. A new review, published in Springer's journal Sex Roles, sheds light on one of the factors contributing to these gender differences in spatial ability, that of gender-roles. Although children are born either male or female, individuals differ in their degree of masculine and feminine identification and endorsement of masculine and feminine gender roles. The review was carried out by David Reilly and David Neumann from Griffith University in Queensland, Australia.

Reilly and Neumann note that studies in their review reported finding larger within-gender variations in spatial ability than between-gender. This then led them to look more specifically at the data on variables within males and females which might be able to explain this.

The researchers analyzed twelve studies which had looked specifically at one aspect of spatial ability, namely mental rotation, in high school pupils, college attendees and young adults. Collectively these studies showed a significant association between masculinity and mental rotation performance for both men and women. In other words, men and women with either a strong masculine or androgynous gender-identity fared better in mental rotation tasks.

The authors suggest that it is the considerable variation in the levels of typically masculine and feminine traits and behaviors, that children of the same sex develop, which account for the inter-gender variability. Masculine identification leads to cultivation of mathematical and scientific skills whereas feminine identification facilitates verbal and language abilities. These gender-roles are not mutually exclusive, with some children of both genders developing a healthy integration of both roles.

Development of spatial ability is refined through play and recreational activities, with traditionally masculine activities helping to promote development of spatial ability. Therefore improving girls' performance in subjects which require good spatial ability may involve the deliberate inclusion of what are commonly seen as stereotypically male activities into their daily lives, rather than encouraging sex-segregation of activities.

The authors conclude: "We have seen many changes in society's beliefs about gender equality in the intervening decades since Sharon Nash proposed her gender-role mediation hypothesis of intellectual development in 1979. However, for spatial ability at least, this association seems as relevant today as when the claim was first made."

Revealing the weapons by which bacteria fight each other

2013-04-04
A new study which was performed jointly at Umeå University and the University of Washington in Seattle, USA, discovered that bacteria can degrade the cell membrane of bacterial competitors with enzymes that do not harm their own membrane. This exciting finding opens the way for the development of new antibacterial drugs to fight bacteria using their own weapons. (NATURE, 2013). During the infection of a host organism, pathogenic bacteria can excrete toxins that cause damage to host cells and tissue. Interestingly, bacteria also use similar mechanisms in competition with ...

Incarceration, marijuana use and suicide attempts may hinder liver transplant eligibility

2013-04-04
Results from an anonymous survey of U.S. transplant providers report that incarceration, marijuana use, and psychiatric diagnoses, particularly suicide attempts, may lower patients' eligibility for liver transplantation. The study published in the April issue of Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, also found that most providers would not offer transplants to patients with advanced age, those severely obese, or with lifetime imprisonment. "For patients with end-stage ...

Bronze warship ram reveals secrets

2013-04-04
Analysis of a bronze battering ram from a 2000 year-old warship sheds light on how such an object would have been made in ancient times. Known as the Belgammel Ram, the 20kg artefact was discovered by a group of British divers off the coast of Libya near Tobruk in 1964. The ram is from a small Greek or Roman warship – a "tesseraria". These ships were equipped with massive bronze rams on the bow at the waterline and were used for ramming the side timbers of enemy ships. At 65cm long, the Belgammel Ram is smaller in size and would have been sited on the upper level on the ...

Notre Dame study finds Asian carp DNA not widespread in the Great Lakes

2013-04-04
Scientists from the University of Notre Dame, The Nature Conservancy, and Central Michigan University have presented their findings of Asian carp DNA throughout the Great Lakes in a study published in the Canadian Journal of Fisheries and Aquatic Sciences. "The good news is that we have found no evidence that Asian carp are widespread in the Great Lakes basin, despite extensive surveys in Southern Lake Michigan and parts of lakes Erie and St Clair," Christopher Jerde, the paper's lead author and a scientist at the University of Notre Dame, said. "Looking at the overall ...

Shift of language function to right hemisphere impedes post-stroke aphasia recovery

2013-04-04
Amsterdam, NL, April 4, 2013 – In a study designed to differentiate why some stroke patients recover from aphasia and others do not, investigators have found that a compensatory reorganization of language function to right hemispheric brain regions bodes poorly for language recovery. Patients who recovered from aphasia showed a return to normal left-hemispheric language activation patterns. These results, which may open up new rehabilitation strategies, are available in the current issue of Restorative Neurology and Neuroscience. "Overall, approximately 30% of patients ...

Body representation differs in children and adults

2013-04-04
Children's sense of having and owning a body differs from that of adults, indicating that our sense of physical self develops over time, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. Many of our senses — vision, touch, and body orientation — come together to inform our perception of having and owning a body. Psychological scientist Dorothy Cowie of Goldsmiths, University of London and colleagues hypothesized that there might be age differences in how these processes come together. To test this hypothesis, ...

Hubble breaks record in search for farthest supernova

2013-04-04
NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago. SN Wilson belongs to a special class called Type Ia supernovae. These bright beacons are prized by astronomers because they provide a consistent level of brightness that can be used to measure the expansion of space. They also yield clues to the nature of dark energy, the mysterious force accelerating the rate of expansion. "This new ...

ORNL's awake imaging device moves diagnostics field forward

2013-04-04
A technology being developed at Oak Ridge National Laboratory promises to provide clear images of the brains of children, the elderly and people with Parkinson's and other diseases without the use of uncomfortable or intrusive restraints. Awake imaging provides motion compensation reconstruction, which removes blur caused by motion, allowing physicians to get a transparent picture of the functioning brain without anesthetics that can mask conditions and alter test results. The use of anesthetics, patient restraints or both is not ideal because they can trigger brain activities ...

For the first time, researchers isolate adult stem cells from human intestinal tissue

2013-04-04
CHAPEL HILL, N.C. – For the first time, researchers at the University of North Carolina at Chapel Hill have isolated adult stem cells from human intestinal tissue. The accomplishment provides a much-needed resource for scientists eager to uncover the true mechanisms of human stem cell biology. It also enables them to explore new tactics to treat inflammatory bowel disease or to ameliorate the side effects of chemotherapy and radiation, which often damage the gut. "Not having these cells to study has been a significant roadblock to research," said senior study author ...

Assessing disease surveillance and notification systems after a pandemic

2013-04-04
WASHINGTON -- Significant investments over the past decade into disease surveillance and notification systems appear to have "paid off" and the systems "work remarkably well," says a Georgetown University Medical Center researcher who examined the public health response systems during the 2009 H1N1 influenza pandemic. The findings are published online today in PLOS ONE. After the Sept. 11 terrorist attacks in the U.S. and the potential threat of bioterrorism, many new advanced systems for disease surveillance and notification have been developed and implemented throughout ...
