Through history women have been the butt of smirking male jokes about their alleged inability to give directions or to read road maps. Now, researchers at the Ruhr University in Bochum, Germany, have discovered that a woman's spatial ability, and hence her ability to read maps, actually increases during her menstrual period.
During most of her monthly cycle, higher levels of the female hormone estrogen are present and these were linked to lower scores on such things as direction finding and map reading. But when levels of the male hormone testosterone were higher, as during their period, women did better.
The interesting evolutionary question is why was it necessary for women to be better spatially orientated during their periods?
If women tended to do more gathering and men more hunting, women should be expected to be better at locating, identifying, and remembering biological kinds. And there is some evidence that this is the case: women perform better at tasks of recalling objects.
The proper domain would of course be plants, but the actual domain appears to include the stationary environment in general, so that this skill may be seen as a spatial ability. The botanical classification systems of primitive tribes bear witness to an impressive memory capacity that may be domain-specific.
The monthly cycle of hormones could conceivably have been linked to cycles of the moon, knowledge of which was vital to early hunters and gatherers.
The research could partly explain the age-old stories about witches collecting herbs during the cycle of the full moon when their "magical" powers of detection were at their peak.
Another advantage that women have is the uncanny ability (from a man's point of view) to read another person's face, and here, too, the Bochum University researchers have come up with some startling findings. Their research suggests that the brain may be functionally specialized for individual emotions.
Neuropsychologist Reiner Sprengelmeyer of Ruhr University in Bochum recently investigated this aspect of the disease by asking patients to identify the changing emotions expressed by a face on a computer screen.
He found that Huntington's patients have problems recognizing all emotions except happiness, but experience the greatest difficulty of all in identifying disgust. Sprengelmeyer believes that disgust is an emotion that arose early in our evolutionary history, perhaps as a non-verbal warning of spoiled food. And as it arose, a specific part of the brain became dedicated to its recognition. This structure, he thinks, may reside in the caudate nucleus, a part of the brain involved in cognition and movement that is always destroyed by Huntingdon's.
"There is a long-standing hypothesis that all emotions are processed by the same brain structure," he said. "Our finding suggests that there are several structures that are important for decoding different emotions."
One unanswered question remains: Why is it men never admit they've misread a road map and refuse to stop and ask somebody for directions?
THE ‘MONSTER’: The Philippines on Saturday sent a vessel to confront a 12,000-tonne Chinese ship that had entered its exclusive economic zone The Philippines yesterday said it deployed a coast guard ship to challenge Chinese patrol boats attempting to “alter the existing status quo” of the disputed South China Sea. Philippine Coast Guard spokesman Commodore Jay Tarriela said Chinese patrol ships had this year come as close as 60 nautical miles (111km) west of the main Philippine island of Luzon. “Their goal is to normalize such deployments, and if these actions go unnoticed and unchallenged, it will enable them to alter the existing status quo,” he said in a statement. He later told reporters that Manila had deployed a coast guard ship to the area
A group of Uyghur men who were detained in Thailand more than one decade ago said that the Thai government is preparing to deport them to China, alarming activists and family members who say the men are at risk of abuse and torture if they are sent back. Forty-three Uyghur men held in Bangkok made a public appeal to halt what they called an imminent threat of deportation. “We could be imprisoned and we might even lose our lives,” the letter said. “We urgently appeal to all international organizations and countries concerned with human rights to intervene immediately to save us from
RISING TENSIONS: The nations’ three leaders discussed China’s ‘dangerous and unlawful behavior in the South China Sea,’ and agreed on the importance of continued coordination Japan, the Philippines and the US vowed to further deepen cooperation under a trilateral arrangement in the face of rising tensions in Asia’s waters, the three nations said following a call among their leaders. Japanese Prime Minister Shigeru Ishiba, Philippine President Ferdinand Marcos Jr and outgoing US President Joe Biden met via videoconference on Monday morning. Marcos’ communications office said the leaders “agreed to enhance and deepen economic, maritime and technology cooperation.” The call followed a first-of-its-kind summit meeting of Marcos, Biden and then-Japanese prime minister Fumio Kishida in Washington in April last year that led to a vow to uphold international
US president-elect Donald Trump is not typically known for his calm or reserve, but in a craftsman’s workshop in rural China he sits in divine contemplation. Cross-legged with his eyes half-closed in a pose evoking the Buddha, this porcelain version of the divisive US leader-in-waiting is the work of designer and sculptor Hong Jinshi (洪金世). The Zen-like figures — which Hong sells for between 999 and 20,000 yuan (US$136 to US$2,728) depending on their size — first went viral in 2021 on the e-commerce platform Taobao, attracting national headlines. Ahead of the real-estate magnate’s inauguration for a second term on Monday next week,
